*Directions to Solve*

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.

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%)

@All.

50% increase means 150 (50+100) and 15% means 115.

50% increase means 150 (50+100) and 15% means 115.

From where did 28 come?

The answer should be D here "None of these".

The chart shows market share in %, all percentages together is 100%. Somehow total share should not exceed more than 100%. All companies together market share should be 100%. In this case, when sale % increases market share is gone to 116.1% which will not be correct.

If you want to balance, other companies market share to be reduced to balance to 100%. So the answer can be D.

If I'm wrong please explain me in a little better way how the answer is A?

Because they have specified it to be in terms of value.
