155%

C.

221%

D.

171%

#### SOLUTION

Solution : C

Let total population of Delhi and Mumbai in 2004 = 100
Number of men in Delhi and Mumbai = 60
Therefore number of males in 2011 = 60 × (1.2)7 = 60 × 3.583 215
Therefore number of females in 2011= 40 × (1.15)7 = 40 × 2.66 106
Therefore total population of Delhi and Mumbai in 2011 = 321

% growth of population = (321100)100 × 100  221%.

While the population in Kolkata and Bangalore has been growing steadily towards that of the Delhi and Mumbai, the growth rate in Kolkata and Bangalore seems to be declining.

If the population in the country in the year 1980 was 800 mn, how many million votes did the party secure in this election?

A.

162

B.

360

C.

266.4

D.

None of these

#### SOLUTION

Solution : A

In 1989,out of 800 million people,  60 percent were eligible to vote, out of them, around 75% turned up for voting, out of those 75%,only 45% voted for the party. Hence the number of votes secured by the party=(35)×(34)×(45100)×800=162mn.

If the population growth from 1998 to 2000 was 10 %, what is the ratio of total population in 1998 to the number of people who voted for the party in 2000(approx)?

A.

125 : 11

B.

2500 : 231

C.

1250 : 231

D.

Cannot be determined

#### SOLUTION

Solution : C

Let the population in 1998 be 100.
Then population in 2000 is 110.
So number of people who voted for the party in 2000 = 110 × (40100) × (60100) × (70100)
So the required ratio is 100110×25×35×70100 = 1250231

What is the ratio of the number of people who did not vote to the number of people who voted for the party in 2000?

Which one of the following is an acceptable listing of films to show this week?

A.

Shout, Mist, Trek, QuePasa, Fly, andJealousy

B.

Shout, Mist, Trek, Fly, Jealousy, and AbraCadabra

C.

QuePasa, Lessons, Mist, Shout, AbraCadabra, and Trek

D.

Shout, Lessons, Mist, Trek, Fly, and Jealousy

#### SOLUTION

Solution : B

In option A, there are two foreign films and this violating the third statement.
Option C and D, violating first statement.
Option B is the correct answer.

If Shout starts at 8:30, Mist at 8:15, Trek at 8:00, Fly at 7:45, Jealousy at 7:30, and AbraCadabra at 7:15, and each movie is exactly two hours long, at what time will the next showing of Trek start?

A.

10:20

B.

10:15

C.

10:30

D.

10:45

#### SOLUTION

Solution : C

The first showing of Trek will be over at 10:00. Then, the employees will need 20 minutes to clean the theater, which is 10:20. Since the movies always start on the quarter hour, the second showing of Trek will be 10:30. Option (c)

The movies this week are showing in the following theaters:

Theatre 1ShoutTheatre 2AbraCadabraTheatre 4JealousyTheatre 5FlyTheatre 6Mist

Shout is doing the most business, followed by Trek and, to the management's surprise, Mist. The management wants to move Mist to a larger theater. Which theater is the most logical?

A.

theater 1

B.

theater 2

C.

theater 3

D.

theater 5

#### SOLUTION

Solution : D

Since Shout is doing the most business and Trek the second most, they should remain in the two largest theaters. Also, the theater never shows a foreign film in the largest theater. Theaters 3 and 4 must show the movies that are rated G and PG, so the movies that are there must stay there. The most logical choice is to put Mist in theater 5 and Fly in theater 6. Option (d)

In a certain perfume mixture consisting of only two flavors, for every 3 milliliters of Flavour A, there are 7 milliliters of Flavour B. After 10 milliliters of Flavour C are added to this perfume mixture, what is the ratio of the quantities of Flavour A to Flavour C?
1. Before flavour C was added, there were 50 milliliters of perfume mixture.
2. After flavour C was added, there were 60 milliliters of perfume mixture.

A. A
B. B
C. C
D. D

#### SOLUTION

Solution : B

The question stem already tells us that there are 10 milliliters of Flavour C in the final perfume mixture. We also know that the original perfume mixture consists of only Flavours A and B in the ratio of 3 to 7. Thus, we need the original volume of the perfume mixture to determine the amount of FlavourA contained in it.
SUFFICIENT: This tells us that original perfume mixture was 50 milliliters. Thus, there must have been 15 milliliters of Flavour A (to 35 milliliters of Flavour B). Theratio of A to C is 15 to 10 (or 3 to 2).
SUFFICIENT: This tells us that the final perfume mixture was 60 milliliters. We know that this includes 10 milliliters of Flavour C. This means the original perfume mixture contained 50 milliliters. Thus, there must have been 15 milliliters of Flavour A (to 35 milliliter of Flavour B). The ratio of A to C is 15 to 10 (or 3 to 2).

What is the perimeter of isosceles triangle ABC?
1. The length of side AB is 9
2. The length of side BC is 4

A. A
B. B
C. C
D. D

#### SOLUTION

Solution : C

The perimeter of a triangle is equal to the sum of the three sides.
(1) INSUFFICIENT: Knowing the length of one side of the triangle is not enough to find the sum of all three sides.
(2) INSUFFICIENT: Knowing the length of one side of the triangle is not enough to find the sum of all three sides.
Together, the two statements are SUFFICIENT. Triangle ABC is an isosceles triangle which means that there are theoretically 2 possible scenarios for the lengths of the three sides of the triangle:(1)AB = 9, BC = 4 and the thirdside, AC = 9 or (1)AB = 9,BC = 4 and the third side AC = 4.
These two scenarios lead to two different perimeters for triangle ABC, HOWEVER, upon careful observation we see that the second scenario is an IMPOSSIBILITY. A triangle with three sides of 4, 4, and 9 is not a triangle. Recall that any two sides of a triangle must sum up to be greater than the third side. 4 + 4 < 9 so these are not valid lengths for the side of a triangle.
Therefore the actual sides of the triangle must be AB = 9, BC = 4, and AC = 9. The perimeter is 22.

So we do not have any information regarding incomes of B and F. So their average savings is 70+202= 45.

If E's income saw an increase of 10% in 2012 and if his expenses remained same, what is the percentage change in his savings as a percentage of his incomes for the two years?

A.

18.18%

B.

27.27%

C.

9.1%

D.

11.11%

#### SOLUTION

Solution : C

E's income in 2011 = 200
Savings as a percentage of income in 2011= 10%
E's income in 2012 = 220
Savings as a percentage of income in 2012 = (40220) × 100=18.18%

So percentage change = 81.8%

If expense on rent as a percentage of income of F is 12.5%, then the other expenses as a percentage of his savings is___

#### SOLUTION

Solution : Income of C = 160
So expense on rent= 20
Remaining expenses = 120
So the required answer = (12020) × 100=600%  The above pie chart shows the contribution of various factors towards the price in 2008

If the manufacturing cost and the profit remained constant for 2008 and 2009, and if the logistics cost for 2008 and 2009 were Rs 200 and Rs 270, what was the percentage increase in raw material cost?

A.

40

B.

50

C.

60

D.

cannot be determined

#### SOLUTION

Solution : C

Logistics cost for 2008 = Rs 200
So, total cost = Rs 1000
Hence, Raw material cost in 2008 = Rs 300
Total cost in 2009 =Rs 1250
So increase in raw material cost = Rs 180

Therefore, percentage increase = 60%

There are three boxes, one contains only apples, one contains only oranges, and one contains both apples and oranges. The boxes have been incorrectly labeled such that no label identifies the actual contents of the box it labels. Opening just one box, and without looking in the box, you take out one piece of fruit. By looking at the fruit, you can immediately label all of the boxes correctly. Which box did you open?

A.

Containing apple

B.

Containing oranges

C.

Containing both apples and oranges

D.

Cannot be determined

#### SOLUTION

Solution : C

The box that must be opened is the one labeled "apples and oranges." By definition, whichever fruit is inside; is the only fruit type that that box contains. Let's say that you found an apple in that box that was labeled with both apples and oranges; because you know it must therefore only contain apples, then you conclude that the box that is labeled "oranges" cannot contain only oranges, as all boxes have been said to be mislabeled. Thus, the box labeled "oranges" must contain both apples and oranges, leaving the box labeled "apples" to contain only oranges.
