2. What is the central angle of the sector corresponding to the expenditure incurred on Royalty?

A. 15º B. 24º

C. 54º D. 48º


Answer: Option C

Explanation:

Central angle corresponding to Royalty

= (15% of 360)º

= 15x 360

= 54º.


3. The price of the book is marked 20% above the C.P. If the marked price of the book is Rs. 180, then what is the cost of the paper used in a single copy of the book?

A. Rs. 36 B. Rs. 37.50

C. Rs. 42 D. Rs. 44.25


Answer: Option B

Explanation:

Clearly, marked price of the book = 120% of C.P.

Also, cost of paper = 25% of C.P

Let the cost of paper for a single book be Rs. n.

Then, 120 : 25 = 180 : n n = Rs. 25 x 180= Rs. 37.50 .

120


4. If 5500 copies are published and the transportation cost on them amounts to Rs. 82500, then what should be the selling price of the book so that the publisher can earn a profit of 25%?

A. Rs. 187.50 B. Rs. 191.50

C. Rs. 175 D. Rs. 180


Answer: Option A

Explanation:

For the publisher to earn a profit of 25%, S.P. = 125% of C.P.

Also Transportation Cost = 10% of C.P.

Let the S.P. of 5500 books be Rs. x.

Then, 10 : 125 = 82500 : x x = Rs.125 x 82500

= Rs. 1031250.10

S.P. of one book = Rs.1031250

= Rs. 187.50 .5500


5. Royalty on the book is less than the printing cost by:

A. 5% B.33

1%

5

C. 20% D. 25%


Answer: Option D

Explanation:

Printing Cost of book = 20% of C.P.

Royalty on book = 15% of C.P.

Difference = (20% of C.P.) - (15% of C.P) = 5% of C.P.

Percentage difference =Difference

x 100 %Printing Cost

=5% of C.P.

x 100 % = 25%.Printing Cost

6. If the difference between the two expenditures are represented by 18º in the pie-chart, then these expenditures possibly are

A. Binding Cost and Promotion Cost

B. Paper Cost and Royalty

C. Binding Cost and Printing Cost

D. Paper Cost and Printing Cost


Answer: Option D

Explanation:

Central angle of 18º =18

x 100 % of the total expenditure360

= 5% of the total expenditure.

From the given chart it is clear that:

Out of the given combinations, only in combination (d) the difference is 5% i.e.

Paper Cost - Printing Cost = (25% - 20%) of the total expenditure

Distribution of Overseas Tourist Traffic from India.

1. What percentage of Indian tourist went to either USA or UK ?

A. 40 % B. 50 %

C. 60 % D. 70 %


Answer: Option B

(40+10) = 50% (from first chart)


2. The ratio of the number of Indian tourists that went to USA to the number of Indian tourists who were below 30 years of age is ?

A. 2:1 B. 8:3

C. 3:8 D. Cannot be determined


Answer: Option B

Explanation:

3. If amongst other countries, Switzerland accounted for 25% of the Indian tourist traffic, and it is known from official Swiss records that a total of 25 lakh Indian tourists had gone to Switzerland during the year, then find the number of 30-39 year old Indian tourists who went abroad in that year ?

A. 18.75 lakh B. 25 lakh

C. 50 lakh D. 75 lakh


Answer: Option D

Explanation:

Tourist traffic from other countries to Swiz is 20%.

Amongst this 20%, 25% of traffic from India.

So, 25% of 20% = 5% corresponds to the Indian traffic in Switzerland.

5 % corresponds to Switzerland's 25 lakh. Hence 15% will be 75 lakh.

The pie chart shows the distribution of New York market share by value of different computer companies in 2005.

The pie chart shows the distribution of New York market share by volume of different computer companies in 2005.

Number of units sold in 2005 in New York = 1,500

Value of units sold in 2005 in New York = US $1,650,000.

1. For the year 2005, which company has realised the lowest average unit sales price for a PC ?

A. Commodore B. IBM

C. Tandy D. Cannot be determined


Answer: Option D

Explanation:

Although it seems to be Commodore, the answer cannot be determined due to the fact that we are unaware of the break-up of the sales value and volume of companies compromising the other categories.


2. Over the period 2005-2006, if sales (value-wise) of IBM PC's increased by 50% and of Apple by 15% assuming that PC sales of all other computer companies remained the same, by what percentage (approximately) would the PC sales in New York (value-wise) increase over the same period ?

A. 16.1 % B. 18 %

C. 14 % D. None of these


Answer: Option A

Explanation:

If we assume the total sales to be 100 in the first year, IBM's sales would go up by 50% (from 28 to 42) contributing an increase of 14 to the total sales value.

Similarly, Apple's increase of 15% would contribute an increase of 2.1 to the total sales value. The net change would be 14 + 2.1 on 100. (i.e., 16.1%)


3. In 2005, the average unit sale price of an IBM PC was approximately (in US$)

A. 3180 B. 2800

C. 393 D. 3080


Answer: Option D

Explanation:

IBM accounts for 28% of the share by value and 10% of the share by volume.

28% of 1650000 = 28 x 1650000/100 = 462000

10% of 1500 = 10 x 1500/100 = 150

Therefore, average unit sale price = 462000/150 = 3080.

The following pie-chart shows the sources of funds to be collected by the National Highways Authority of India (NHAI) for its Phase II projects. Study the pie-chart and answers the question that follow.

Sources of funds to be arranged by NHAI for Phase II projects (in crores Rs.)

1. Near about 20% of the funds are to be arranged through:

A. SPVS B. External Assistance

C. Annuity D. Market Borrowing


Answer: Option B

Explanation:

20% of the total funds to be arranged = Rs. (20% of 57600) crores

= Rs. 11520 crores

Rs. 11486 crores.

Rs. 11486 crores is the amount of funds to be arranged through External Assistance.


2. If NHAI could receive a total of Rs. 9695 crores as External Assistance, by what percent (approximately) should it increase the Market Borrowing to arrange for the shortage of funds?

A. 4.5% B. 7.5%

C. 6% D. 8%


Answer: Option C

Explanation:

Shortage of funds arranged through External Assistance

= Rs. (11486 - 9695) crores

= Rs. 1791 crores.

Increase required in Market Borrowing = Rs. 1791 crores.

Percentage increase required =

1791x 100

3. If the toll is to be collected through an outsourced agency by allowing a maximum 10% commission, how much amount should be permitted to be collected by the outsourced agency, so that the project is supported with Rs. 4910 crores?

A. Rs. 6213 crores B. Rs. 5827 crores

C. Rs. 5401 crores D. Rs. 5316 crores


Answer: Option C

Explanation:

Amount permitted

= (Funds required from Toll for projects of Phase II) + (10% of these funds)

= Rs. 4910 crores + Rs. (10% of 4910) crores

= Rs. (4910 + 491) crores

Y 52

Z 42

R 51

S 49

T 46

V 58

1. If the population of village R in 1997 is 32000, then what will be the population of village Y below poverty line in that year?

A. 14100 B. 15600

C. 16500 D. 17000


Answer: Option B

Explanation:

Population of village R = 32000 (given).

Let the population of village Y be y.

Then, 16 : 15 = 32000 : y y =15 x 32000

= 30000.16

Population of village Y below poverty line = 52% of 30000 = 15600.

A. 11 : 23 B. 13 : 11

C. 23 : 11 D. 11 : 13


Answer: Option C

Explanation:

Let N be the total population of all the seven villages.

Then, population of village T below poverty line = 46% of (21% of N)

and Population of villages Z below the poverty line = 42% of (11% of N)

Required ratio = 46% of (21% of N)=

3. Find the population of village S if the population of village X below poverty line in 1997 is 12160.

A. 18500 B. 20500

C. 22000 D. 26000


Answer: Option C

Explanation:

Let the population of village X be x.

Then, 38% of x = 12160 x =12160 x 100

= 32000.38

Now, if s be the population of village S, then

16 : 11 = 32000 : s s =11 x 3200

= 22000.16


4. If in 1998, the population of villages Y and V increase by 10% each and the percentage of population below poverty line remains unchanged for all the villages, then find the population of village V below poverty line in 1998, given that the population of village Y in 1997 was 30000.

A. 11250 B. 12760

C. 13140 D. 13780


Answer: Option B

Explanation:

Population of village Y in 1997 = 30000 (given).

Let the population of village V in 1997 be v.

Then, 15 : 10 = 30000 : v v =30000 x 10

= 20000.15

Now, population of village V in 1998 = 20000 + (10% of 20000) = 22000.

Population of village V below poverty line in 1998 = 58% of 22000 = 12760.
