know, can surprise us at times with some unknown facet of their personality.

Ans .

(b) 8(1+ √2)

1. Explanation :

Since base of each triangle will be counted once,
Sum of perimeters of the triangles = Perimeter of the
square + 2 × (Sum of its diagonals).
But each of the other two sides of the triangles is common
to two triangles, so it will be counted twice.
Area of the square = 4, therefore length of its side = 2
and perimeter = 8.
Also its diagonal = 2√2.
So the required perimeter = (8 + 2 × 4√2) = 8(1 + √2).

Ans .

(b) 31

1. Explanation :

5^6 – 1 = (5^3)^2 – 1 = (125)^2 – (1)^2 = (125 + 1) (125 – 1)
= 124 × 126 = 31 × 4 × 126.
So among the given answer choices, it is divisible by 31.

Ans .

(a) Ram paid Rs.275 to Prem

1. Explanation :

After 2 years, the price of the flat will be (1)(1.10)^2
= Rs.1.21 lakh.
Correspondingly the price of the land will be
(1.1)(1.05)^2 = Rs.1.21275 lakh.
Hence, the price of the plot = Rs.(1.21275 – 1.21) lakh
= Rs.275 more than that of the flat.
Hence, if they exchange, Ram will have to pay this
amount to Prem .

Ans .

(c) Rs.66

1. Explanation :

For questions 54 to 57:
Please note that the best way to solve this question is by working
backwards.
E.g. after the 4th round, each one of them had Rs.32. Since it is
Vibha who lost in this round, all the remaining three must have
doubled their share.
In other words, they would have had Rs.16 each after the 3rd
round.
Since the increase is of Rs.16 in each one’s share, i.e., Rs.48
overall which comes from Vibha's share, her share before the
4th round was (32 + 48) = Rs.80, after the 3rd round.
Working backwards in this manner, we can get the following
table.

Suvarna started with Rs.66.

Ans .

(d) Vibha

1. Explanation :

d It was Vibha who started with the lowest amount, viz.
Rs.10.

Ans .

(a) Suvarna

1. Explanation :

It was Suvarna who started with the highest amount,
viz. Rs.66.

Ans .

(b) 72

1. Explanation :

At the end of the second round, Uma had Rs.72.

Ans .

(c) Rs.5.51

1. Explanation :

Hint: The best way to solve this question is to multiply
the alternatives by 72 and find which one gives you
the middle three digits as 96.7.
To save time, you can multiply 72 by integer values
only.
E.g. 72 × 3 = 216, 72 × 5 = 360 and 72 × 7 = 504.
It is to be noted that when the decimal part of the
increase.
Let us now roughly multiply the decimal values of the
options also by 72. E.g. 72 x 0.2 = 14.4, 72 × 0.1 = 7.2
and 72 × 0.5 = 36.
So option (a) will yield (216 + 14) = 230
(approximately), (b) will yield (360 + 7) = 367
(approximately), (c) will yield (360 + 36) = 396
(approximately) and (d) will yield (504 + 14) = 528
(approximately).
Of these, only option (c) satisfies our requirement ofv 2nd and 3rd digits being 96.

Ans .

(d) 20

1. Explanation :

Let us assume that the person has Rs.100.
With this, he can buy 50 oranges or 40 mangoes.
In other words, the price of an orange is Rs.2 and that of
a mango is Rs.2.50.
If he decides to keep 10% of his money for taxi fare, he
would be left with Rs.90.
Now if he buys 20 mangoes, he would spend Rs.50 and
will be left with Rs.40.
Thus, he can buy 20 oranges.

Ans .

(a) 100

1. Explanation :

The given expression is of the form $$\frac{x^3 + y^3}{x^2 - xy + y^2 }$$
We know, x^3 + y^3 = (x + y)( x^2 – xy + y^2).
Thus, required value = (x + y) = (55 + 45) = 100.

Ans .

(c) 1 : 3 : 6s

1. Explanation :

The largest angle in a right-angled triangle is 90º, which
corresponds to the highest part of the ratio.
Let us evaluate each option.
In (a), the remaining two angles would be 30º and 60º,
which is possible.
In (b), the remaining two angles would be 45º each,
which is again possible.
In (c), the remaining two angles would be 15º and 45º,
which is not possible as the sum of the angles is not
s 180º.

Ans .

(d) Never divisible by 237

1. Explanation :

Since n(n + 1) are two consecutive integers, one of
them will be even and thus their product will always be
even.
Also, sum of the squares of first ‘n’ natural numbers is
given by $$\frac{n(n + 1) (2n + 1)}{6}$$
Hence, our product will always be divisible by this.
Also you will find that the product is always divisible by
3 (you can use any value of n to verify this).
However, we can find that option (d) is not necessarily
true. E.g. If n = 118, (2n + 1) = 237 or if n = 236, then
(n + 1) = 237 or if n itself is 237, etc.

Ans .

(b) 1 or 5

1. Explanation :

The best way to solve this question is by the method of
simulation. Choose any prime number greater than 6 and
verify the result.
When 7 is divided by 6, it gives a remainder 1. So our
answer could be (a) or (b). When 11 is divided by 6, it
gives a remainder 5. Hence, our answer is (b).

Ans .

*

1. Explanation :

There cannot be four or more blue balls.
Case 1: If there are three blue balls, then they can be
only in box 1, 3 and 5.
Case 2: If there are two blue balls, then total number of
cases = 5C2 = 10
But in 4 cases the blue ball will be in adjacent boxes.
These cases are when blue balls in boxes 1 and 2 or 2
and 3 or 3 and 4 or 4 and 5.
Therefore, total number of cases when there are two
blue balls = 10 – 4 = 6
Case 3: If there is one blue ball, then total number of
cases = 5C1 = 5
Case 4: If there is no blue ball, then total number of
cases = 5C5 = 1
Hence, total number of cases = 1 + 6 + 5 + 1 = 13.
* The correct answer is not available in the given
options.

Ans .

(b) 60°

1. Explanation :

In ΔABC, ∠ACB = 180° – 90° – 30° = 60°.
∴ ∠DCE = 30°, since ∠CDE = 90°.
In ΔCED, ∠CED = 180° – 90° – 30° = 60°.

Ans .

(c) Rs.1,500

1. Explanation :

Using alligation, the ratio of the amounts invested at both
the rates = 2 : 1.
Since he has invested Rs.3,000 at 5%, he should further
invest Rs.1,500 at 8% to earn a total interest of 6% per
annum.

Alternative method:
Let the amount invested at 8% be Rs.x.
Then,
= 3000 × $$\frac{105}{100}$$+ x × $$\frac{108}{100}$$=(3000 + x)$$\frac{106}{100} \ ⇒ 0.02x = 30 ⇒ x = 1,500 ∴ He should further invest Rs.1,500 at 5% to earn a total interest of 6% per annum. Ans . (a) 100 1. Explanation : Let there be 100 voters in all. Initially, 40 of these promised to vote for P, while 60 of them promised to vote for Q. On the last day, (15% of 40) = 6 voters went back of their promise and voted for Q. Also, 25% of 60 = 15 voters shifted their interest from Q to P. So finally, P end up getting (40 – 6 + 15) = 49 votes and Q end up getting (60 – 15 + 6) = 51 votes. Hence, margin of victory for Q = (51 – 49) = 2, which is true. Hence, there were 100 voters in all. Ans . \( \frac{π}{3}$$

1. Explanation :

In the given figure, the area of the circle = πr^s2.
To find out the area of the square, we need to find the
length of the side of the square.
We know, OR = OT + TR = OT + OS = 2r.
In right-angled triangle ORS, OR = 2r and OS = r.
So SR^2 = OR^2 – OS^2.
∴SR^2 = Area of the square = 4r^2 – r^2 = 3r^2.
Hence, the required ratio = $$\frac{π}{3}$$

Ans .

(a) 11.11 m

1. Explanation :

In the same time as A runs 200 m in the race, S runs 180
m and N runs 160 m.
In other words, in the same time as S runs 180 m, N runs
160 m.
So in the same time as S runs 100 m, N will run
100 × $$\frac{160}{180= 88.89 m. Hence, in a 100 m race, S will beat N by (100 – 88.89) = 11.11 m.}$$

Ans .

(b) 14

1. Explanation :

If the numbers are (x – 2), x and (x + 2), then
3(x – 2) – 2 = 2(x + 2) ⇒ x = 12
∴ x + 2 = 14.

Ans .

(a) 165

1. Explanation :

If x men were there on day one, there would be (x – 110)
men on the 12th day.
Hence, on an average, there were (x – 55) men.
The job takes $$\frac{3}{2}$$times the normal time.
Hence, the average number of people = $$\frac{2}{3}$$
⇒ x – 55 = $$\frac{2}{3}$$x
Hence, x = 165

Ans .

(a) $$\frac{1}{12}$$

1. Explanation :

Total number of four-digit numbers that can be
formed = 4!. If the number is divisible by 25, then the last two digits are 25. So the first two digits can be arranged in 2! ways. Hence, required probability = $$\frac{2!}{4!}$$= $$\frac{1}{12}$$

Ans .

(c) 10 hr and 8 hr

1. Explanation :

Let the first typist takes X hours and the second takes
Y hours to do the whole job.
When the first was busy typing for 3 hr, the second
was busy only for 2 hr.
Both of them did $$\frac{11}{20}$$of the whole work.
∴ $$\frac{3}{X}$$ + $$\frac{2}{Y}$$ = $$\frac{11}{20}$$
When the assignment was completed, it was revealed
that each typist had done half the work.
∴The first one spent $$\frac{X}{2}$$hr, and the second,$$\frac{Y}{2}$$hr.
And since the first had begun one hour before the
second, we have $$\frac{X}{2}$$ - $$\frac{Y}{2}$$=1

Ans .

(d) 15

1. Explanation :

Since I live X floors above the ground floor and it takes
me 30 s per floor to walk down and 2 s per floor to ride
the lift, it takes 30X s to walk down and 2X s to ride the
lift after waiting 420 s.
⇒ 30X = 2X + 420 ⇒ X = 15.
Alternative method:
X > 14 as time taken to walk has to be greater than
7 min.

Ans .

(d) None of these

1. Explanation :

Since 5-12-13 forms a Pythagorean triplet, the triangle
under consideration is a right-angled triangle with height
12 and base 5.
So area of the triangle =$$\frac{1}{2}$$(12)(5)= 30 sq. units.
If area of the rectangle with length 10 units is 30 sq. unit
Hence, its perimeter = 2(10 + 3) = 26 units.

Ans .

(c) 60

1. Explanation :

Since AD = BC (Opposite sides of a rectangle are equal.)
AB + AC = 5BC and AC – BC = 8 or AC = BC + 8
∴AB = 4(BC – 2)
By Pythagoras’ Theorem, AB^2 + BC^2 = AC^2
Expressing AB and AC in terms of BC we get, BC = 5.
∴ AB = 12 and AC = 13
So area of the rectangle = 5 × 12 = 60.

Ans .

(d) –2

1. Explanation :

If the roots are a and a2, the product of roots = a^3 = –8.
∴ a = –2.
Hence, sum of the roots = k = –(a + a^2) = –(–2 + 4) = – 2.

Ans .

(a) 40°

1. Explanation :

If we draw the imaginary lines AC and BD, we find that
∠CAD and ∠CBD are subtended by the same chord DC.
Thus, ∠DBA = (70° – 30°) = 40°.
Also, ∠DBA and ∠ACD are subtended by the same chord DA.
Hence, ∠ACD = ∠DBA = 40°.

Ans .

(b) 15 m

1. Explanation :

The figure can be drawn as shown above.
Height of the wall = AD = AC = (AB + 3) or AB = (AC – 3).
In right-angled triangle ABC, AB^2 + BC^2 = AC^2.
Thus, (AC – 3)2 + 81 = AC^2.
∴ AC = 15 m.
Hence, height of the wall = 15 m.
Hint: Please note that the same multiple of all the triplets
should also be triplets. E.g. if 3-4-5 is a triplet,
then 3(3-4-5) should also be triplet or 9-12-15 is also a triplet.
Note that the base of the triangle is 9, so other two sides
should be 12 and 15.

Ans .

(b) II

1. Explanation :

Profit percentage in each case is (i) 10%
(ii) $$\frac{100 × 100}{90}$$ = $$\frac{100}{9}$$%
(iii)$$\frac{100 × 1.1-100}{100}$$× 100 = 10%
(iv) $$\frac{10 × 100}{95}$$= $$\frac{200}{19}$$%

Ans .

(b) II

1. Explanation :

Let the length of the escalator be 90 ft.
(There is no loss of generality in making this assumption.)
Let the speed of the escalator be y ft per second and the
man’s walking speed be x ft per second.
According to the question, we get
$$\frac{90}{30}$$= x + y
$$\frac{90}{90}$$= x - y
Adding the above equations, we get 2x = 4, i.e., x = 2. ∴ Time taken by the man to walk up the escalator when it is not moving = $$\frac{90}{2}$$= x + y or 45 s.

Ans .

(a) 3

1. Explanation :

Let one of the numbers be x. So the other number would
be(x + 4).
According to the question, we have $$\frac{1}{x}$$ + $$\frac{1}{x+4}$$= 21 or x = 3.
Hint: Please note that the sum of reciprocals is basically
$$\frac{(Sum of the int egers)}{(Product of the int egers)}$$So we have to find two
integers whose sum is 10 and whose product is 21.
So x + (x + 4) = 10 or x = 3.

Ans .

(b) 4 hr and 48 min

1. Explanation :

The bells will chime together after a time that is equal to
the LCM of 18, 24 and 32 = 288 min = 4 hr and 48 min.

Ans .

(c) 2 < m < 5

1. Explanation :

3m^2 – 21m + 30 < 0
∴ m^2 – 7m + 10 < 0 ⇒ (m – 5)(m – 2) < 0.
So either (m – 5) < 0 and (m – 2) > 0 or (m – 2) < 0 and
(m – 5) > 0 (which is not feasible).
Hence, either m < 5 and m > 2, i.e., 2 < m < 5.

Ans .

(d) 726

1. Explanation :

Required cost = 6[1+$$\frac{1000}{100}$$]^2 = 6(11)^2 = 121 × 6 = 726.

Ans .

c) 3

1. Explanation :

If x = 1, we have min(3, 3) = 3.
If x = 2, we have min(6, 0) = 0.
If x = 3, we have min(11, –3) = –3.
If x = 0.5, we have min(2.25, 4.5) = 2.25.
If x = 0.3, we have min(2.09, 5.1) = 2.09.
Thus, we find that as x increases above 1 and when it
decreases below 1, the value of the function decreases.
It is maximum at x = 1 and the corresponding value = 3.

Ans .

(d) 24

1. Explanation :

Let us choose a town, say A.
If I were to consider this as the base town and construct
two roads such that I connect any pair of towns, I get
the following combinations:
1. AB – BC, 2. AB – BD, 3. AC – CB, 4. AC – CD,
From any of these combinations, if I were to construct a
road such that it again comes back to A, then it would
form a triangle.
To avoid a triangle, the third road that I construct should
not be connected to A but to the third town.
Hence, the combination would be:
1. AB – BC – CD, 2. AB – BD – DC, 3. AC – CB – BD,
4. AC – CD – DB, 5. AD – DB – BC and 6. AD – DC – CB.
Thus, from each town, we can construct 6 such
combinations.
Hence, total number of combinations that we can have
from four towns = (6 × 4) = 24.

Ans .

(a) 1

1. Explanation :

If a = –2 and b = –3, then our expression will be
me(–2 + mo(le(–2, –3)), mo(–2 + me(mo(–2), mo(–3)))
= me(–2 + mo(–3), mo(–2 + me(2, 3)))
= me(–2 + 3, mo(–2 + 3))
= me(1, mo(1)) = me(1, 1) = 1.

Ans .

(d) mo(le(a,b)) = le(mo(a), mo(b))

1. Explanation :

the method of simulation, i.e., select any arbitrary values
in the range given and verify whether the option holds
good. E.g. a = 2, b = 3.
In this case, option (a) LHS = mo(le(2, 3)) = mo(2) = 2.
RHS = (me(mo(2), mo(3)) = (me(2, 3)) = 3. Hence, LHS <
RHS.
(b) LHS = mo(le(2, 3)) = mo(2) = 2. RHS = (me(mo(2),
mo(3)) = (me(2, 3)) = 3. Hence, LHS < RHS.
(c) LHS = mo(le(2, 3)) = mo(2) = 2. RHS = (le(mo(2),
mo(3)) = le(2, 3) = 2. Hence, LHS = RHS.
(d) LHS = mo(le(2, 3)) = mo(2) = 2. RHS = (le(mo(2),
mo(3)) = le(2, 3) = 2. Hence, LHS = RHS.

Ans .

(b) 0 < a

1. Explanation :

specified.
(a) a > 3. Let a = 4.
So me(a2 – 3a, a – 3) = me(4, 1) = 4 > 0.
(b) 0 < a < 3. Let a = 2.
So me(a2 – 3a, a – 3) = me(–2, –1) = –1 < 0.
(c) a < 0. Let a = –1.
So me(a2 – 3a, a – 3) = me(4, –4) = 4 > 0.
(d) a = 3, me(a2 – 3a, a – 3) = me(0, 0) = 0.

Ans .

(d) Both b and c

1. Explanation :

We can work this on the above lines. E.g.
(a) a > 3. Let a = 4. So le(a^2 – 3a, a – 3) = le(4, 1)
= 1 > 0.
(b) 0 < a < 3. Let a = 2. So le(a^2 – 3a, a – 3) = le(–2, –1)
= –2 < 0.
(c) a < 0. Let a = –1. So le(a^2 – 3a, a – 3) = le(4, –4)
= –4 < 0.

Ans .

(a)

1. Explanation :

Statement I suggests that xyz is odd. This is only possible
if all three of them are odd.
Hence, z – x is even.
So only statement I is required to answer the question.

Ans .

(d)

1. Explanation :

Statement I is useless as it only tells that if x and y are
consecutive positive even integers, then (x – y)^2 has to
be equal to 4.
Statement II suggests the possibility that the numbers
could be 2 and 4. But it does not suggest which is x and
which is y.
Hence, we cannot find the value of x using either
statements.

Ans .

(a)

1. Explanation :

It is clear that only statement I is required to answer the question, if CP = 0.8 SP, then SP = $$\frac{1}{0.8}$$ CP. ∴SP = 1.25 CP
Thus, profit percentage is 25.

Ans .

(c)

1. Explanation :

Both statements are required to answer the question.
Statement I tells us that the triangle is an isosceles triangle.
In an isosceles triangle, the altitude is also the median.
Hence, if we know the altitude and the length of the
congruent sides in an isosceles triangle, we can find its
base and area.

Ans .

(b)

1. Explanation :

Statement II in itself suggests the price of a banana.
Since we can buy 48 bananas in Rs.12, price of a banana
= Re.0.25. And since this price is after 50% reduction,
the actual price of a banana = Re.0.5.

Ans .

(a)

1. Explanation :

Since 116 is less than 112, it can be figured out that both
the first two terms of the AP should be less than 10.
There is only one pair of positive integers whose squares
add up to 116 and they are 10 and 4.
Thus, these two should be the first two terms of the AP.
Hence, the first term is 4, and can be obtained only from
statement I.
Statement II merely suggests that the fifth term is of the
form 7k. Nothing correct can be concluded from this.

Ans .

(c)

1. Explanation :

This can be solved using both the statements together.
From statement I, we know that L × B = 48 or B = $$\frac{L}{48}$$
From statement II, we know L^2 + B^2 = 100
Combining statements I and II,
L^2 + ($$\frac{L}{48}$$)^2 = 100.
L is the only unknown in this equation and can be found
out.

Ans .

(c)

1. Explanation :

We know that product of two numbers = LCM × HCF
= 36 × 2 = 72.
So x = $$\frac{72}{18}$$= 4.
Hence, both the statements are required to answer the
question.

Ans .

(c)

1. Explanation :

This can be answered using both the statements.
Statement II suggests that both t and z are odd.
Statement I suggests that (x + y + t) is even.
Since the difference between an even and an odd
number is always odd, (x + y + t) – z will be odd.

Ans .

(b) 50%

1. Explanation :

It can be seen that the market share of CO in Kolkata has
halved in 1994. None of the other products show such a
drastic decrease in any city. Hence, percentage
decrease in market share = 50%.

Ans .

(b) 1

1. Explanation :

Only MT doubled its market share in Kolkata in 1993-94.

Ans .

(a) 23%

1. Explanation :

Percentage increase = (160 – 130) $$\frac{100}{130}$$= $$\frac{300}{13}$$(a) 23% = 23%.

Ans .

(b) Rs.25 lakh

1. Explanation :

Interest in 1990-91 = 30% of 130 = Rs.39 lakh
Interest in 1991-92 = 40% of 160 = Rs.64 lakh
Hence, required difference = (64 – 39) = Rs.25 lakh

Ans .

(d) Rs.515 lakh

1. Explanation :

Total interest = (30% of 130) + (40% of 160) = (39 + 64)
= Rs.103 lakh.
If this total interest is charged on borrowed funds, then
(20% of borrowed funds) = 103. Hence, borrowed funds
= (5 × 103) = Rs.515 lakh.

Ans .

(d) lower by 1.5%

1. Explanation :

Retained profit in 1990-91 = (25% of 130) = Rs.32.5 lakh
Retained profit in 1991-92 = (20% of 160) = Rs.32 lakh
Hence, percentage change in retained profit
= $$\frac{32.5 − 32}{32.5}$$ = 1.5% lower.

Ans .

(c) Rs.12.8 lakh

1. Explanation :

Total dividend earned by shareholders in 1991-92
= (8% of 160) = Rs.12.8 lakh.

Ans .

(b) 1988-89

1. Explanation :

Trade deficit = Imports – Exports, was the highest for the
year 1988-89, viz. 7 billion dollars.

Ans .

(d) 4

1. Explanation :

Trade deficit is less than that in the succeeding year in
1987-88, 1989-90, 1991-92 and 1993-94.

Ans .

(c) 90%

1. Explanation :

Required percentage = $$\frac{18}{20}$$ × 100 = 90%

Ans .

(d) 88%

1. Explanation :

In the last three years, Imports = (22 + 23 + 27) = 72 and
Exports = (18 + 21 + 24) = 63. Hence, the required
percentage = $$\frac{63}{72}$$ × 100 = 87.5% = 88% (approximately).

Ans .

(a) I only

1. Explanation :

The first statement is obviously true as the trade deficit
in each year is less than the export earning. The export
earning has remained constant for three years between
1990 and 1993. Hence, statement II is not true. Even
statement III is not true as the exports in 1994-95 is more
than the imports in 1993-94.

Ans .

(c) 1991

1. Explanation :

For questions 171 to 175: The graph given in the question can
be depicted in the following table:

The highest change in the revenue obtained from journals
is (47 – 45) = 2 in 1991.

Ans .

(a) 45%

1. Explanation :

In 1992, percentage of total revenue that came from
books = $$\frac{79}{173}$$ × 100 = 45.6% = 45% (approximately).

Ans .

(b) 2

1. Explanation :

In 1990, there was an increase in revenue for all the 3
categories. In 1991, it increased for magazines and books.
And in 1992, it increased only for magazines. So the
answer is b, viz. 2 years.

Ans .

(d) Rs.177 lakh

1. Explanation :

Growth rate in 1992 over 1991 = $$\frac{(173 −169)}{169}$$= 2.36%.
If this rate remained same in 1993 as well, then the
revenue in 1993 would be 173 × $$\frac{(173 −150)}{150}$$ = Rs. 177
lakh.

Ans .

(c) 15%

1. Explanation :

Percentage growth in the total revenue from 1989 to
1992 = $$\frac{(173 −150)}{150}$$ = 15.33% = 15% (approximately).

Ans .

(b) 160

1. Explanation :

Since time taken to manufacture Q by both the machines
is the least, we have to manufacture only Q in order to
maximize the output for the day. In such a case, total
number of units of Q produced by M1 = $$\frac{(8 × 60)}{6}$$ = 80
units and that by M2 = $$\frac{(8 × 60)}{6}$$ = 80 units. So the maximum
number of units that can be produced in one day
= (80 + 80) = 160 units.

Ans .

(d) 119

1. Explanation :

If M1 works at half of its normal efficiency, time taken by
M1 to manufacture 1 unit of P = 20 min and Q = 12 min.
For producing maximum number of units, we have to
produce Q on M2 first as it takes only 6 min per piece.
Also since at least one unit of P has to be manufactured
and it is more efficient to do so on M2, we would do that.
So time taken to manufacture 1 unit of P on M2 = 8 min.
Hence, time remaining on M2 = (480 – 8) = 472. In this
remaining time number of units of Q that can be
manufactured on M2 = $$\frac{472}{6}$$ = 78 (only completed units
taken). Now since it takes less time to manufacture Q on
M1 as well, we will maximize Q on M1. Since 1 unit of
number of units that can be produced = $$\frac{(8 × 60)}{12}$$ = 78 = 40.
Hence, the total number of units manufactured = (1 + 78 + 40) = 119 units.

Ans .

(a) 6 hr 30 min

1. Explanation :

In order to minimize time required, we will manufacture P
on M2 and Q on M1. Number of machine hours required
to manufacture 30 units of P on M2 = (30 × 8) = 240 min
= 4 hr. Number of machine hours required to manufacture
25 units of Q on M1 = (25 × 6) = 150 min = 2.5 hr. So total
time taken = (4 + 2.5) = 6.5 hr or 6 hr 30 min.

Ans .

(a) 0 min

1. Explanation :

Since P has to be produced in more number than Q and
since time taken to produce P is least on M2, to maximize
the output utilize the entire time available on M2 for
producing P. Number of units of P produced in this time
= $$\frac{(8 × 60)}{8}$$ = 60 units. Now since the number of units of
Q should be one-third that of P, we should manufacture
20 units of Q. To manufacture this on M1, it would take
(20 × 6) = 120 min. So there are still (480 – 120) = 360 min
of M1 to be utilized. Now for every 3 units of P that is
manufactured, we have to manufacture 1 unit of Q. To
run one such cycle on M1, it would take (3 × 10 + 1 × 6)
= 36 min. Hence in 360 min, we have 10 such cycles and
utilize all the idle time of M1. Hence, to maximize the
output under the given condition it is possible to have no
idle time on any of the machines.

Ans .

(c) 53 of each with 10 min idle

1. Explanation :

The least efficient way is the option that gives least
production with highest idle time. So we can compare
the options in the following two ways. Assume that
production is constant (viz. LCM of 48, 64, 53 and 71) in
all 4 options and compare the corresponding idle time. Or
we can assume the idle time to be constant (viz. LCM of
3, 12, 10 and 9) in all 4 options and compare the
corresponding production. The latter method is more
preferable as finding LCM of idle time is easier. So LCM
of 3, 12, 10, 9 = 180. If we assume that the idle time has
to be 180 min, then as per option (a) we would get
production = ($$\frac{180}{3}$$× 48) = 2,880 units, as per option (b),

we would get production = ($$\frac{180}{12}$$× 64) = 960 units, as

per option (c), production = ( $$\frac{180}{10}$$× 53 ) = 954 units and
as per option (d), production = ( $$\frac{180}{9}$$× 71 )= 1,420 units.

Since option (c) gives the least production, it is the least
efficient way.

Ans .

(a) 1,50,000 m

1. Explanation :

Total requirement of cloth
= Total number of shirts × Cloth required per shirt
= (20 + 30 + 30 + 10 + 10) × 1000 × 1.5 = 1,50,000 m.

Ans .

(b)46,500 m

1. Explanation :

Total low quality cloth consumed
= 1.5 (30% of 30000 + 30% of 30000 + 40% of 10000
+ 90% of 10000) = 46,500 m.

Ans .

(c) 24,000 m

1. Explanation :

Total quantity of high quality cloth consumed by A-type
shirts = (80% of 20000) × 1.5 = 24,000 m.

Ans .

(d) Cannot be determined

1. Explanation :

We only know the relationship between the type of shirt
and cloth used and type of shirt and dye used. We
cannot find any relationship between type of cloth and
dye used.

Ans .

(b) 2 : 1

1. Explanation :

Amount of low quality die used for C-type shirts
= (40% of 30000) = 12,000 units.
Amount of low quality die used for D-type shirts
= (60% of 10000) = 6,000 units.
Hence, required ratio = $$\frac{12000}{6000}$$= 2 : 1.
