1.  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

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%)
