*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%)

50% of 28 = 28*(50/100) = 14,

15%of 14=14*(15/100) = 2.1.

Therefore total increased = 14+2.1 = 16.1.

15%of 14=14*(15/100) = 2.1.

Therefore total increased = 14+2.1 = 16.1.

At last step, why did you do multiplication with 100 and divide 100 with 16.1?

@All.

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

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