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.
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 ?
Answer: Option
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%)

Total sales in value in 2005 = US $1,650,000.
Since this is all about percentage the value doesn't matter.
So we assume the total sales in value in 2005 = US$100(instead of 1650000)
In 2005 IBM's contribution was 28% = $28(in cash)
IBM got 50% increase in sales ie $14 (14% of 100)
In 2005 Apples's contribution was 14% = $14(in cash)
Apple got 15% increase in sales ie $ $2.1 (2.1% of 100)
The net increase in sales = 14+2.1
=16.1
%ge increase in sales = 16.1*100/100
= 16.1
