The pie chart shows the distribution of New York market share by value of different computer companies in 2016.


The pie chart shows the distribution of New York market share by volume of different computer companies in 2016.

Number of units sold in 2016 in New York = 1,500

Value of units sold in 2016 in New York = US $1,650,000.


Question 1
In 2016, the average unit sale price of an IBM PC was approximately (in US$) :

A
3180
B
3080
C
2800
D
393
Correct Answer: Option 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.

Question 2
For the year 2016, which company has realised the lowest average unit sales price for a PC ?

A
Commodore
B
Tandy
C
IBM
D
Cannot be determined
Correct Answer: Option D

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.

Question 3
Over the period 2016-2017, if sales (value wise) of IBM PC's increased by 50% and Apple by 15% assuming that PC sales of all other computer companies remained same, by what percentage (approximately) would the PC sales in New York (value wise) increase over the same period ?

A
16.1 %
B
14 %
C
18 %
D
None of these
Correct Answer: Option 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%)
