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

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

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

A.

3180

B.

2800

C.

393

D.

3080

Correct answer is D

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

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

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

Correct answer is A

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%)

The following pie charts exhibit the distribution of the overseas tourist traffic from India. The two charts shows the tourist distribution by country and the age profiles of the tourists respectively.

Distribution of Overseas Tourist Traffic from India.

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

Correct answer is D

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 following pie-chart shows the percentage distribution of the expenditure incurred in publishing a book. Study the pie-chart and the answer the questions based on it.

Various Expenditures (in percentage) Incurred in Publishing a Book

Which two expenditures together have central angle of 108°?

A.

Biding Cost and Transportation Cost

B.

Printing Cost and Paper Cost

C.

Royalty and Promotion Cost

D.

Binding Cost and Paper Cost

Correct answer is A

Central angle of 108° = ( 108/360 x 100 ) % of the total expenditure

= 30% of the total expenditure.

From the pie chart it is clear that:

Binding Cost + Transportation Cost = (20% + 10%) of the total expenditure

= 30% of the total expenditure.

Therefore Binding Cost and Transportation Cost together have a central angle of 108°
