**Common Information**

Use the pie charts below to answer the following questions.

The pie chart in Figure (a) shows the distribution of the New York market share **by value** of different computer companies in 2005.

The pie chart in Figure (b) shows the distribution of the 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.

Q. |
Over the period 205-06, if sales (value-wise) of IBM PCs 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? |

✔ A. |
16.1% |

✖ B. |
18.3% |

✖ C. |
14.5% |

✖ D. |
None of these |

**Solution:**

Option(**A**) is correct

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 he $14 + 2.1$ on 100, i.e., $\textbf{16.1%}$
