For the year 2005, which company has realised the lowest average unit sales price for a PC ?

A. Commodore B. IBM
C. Tandy D. Cannot be determined

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 ?

A. 16.1 % B. 18 %
C. 14 % D. None of these
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%)


In 2005, the average unit sale price of an IBM PC was approximately (in US$)

A. 3180 B. 2800
C. 393 D. 3080
Explanation: IBM accounts for 28% of the share by value and 10% of the share by volume. 28% of 1650000 = 28 x 1650000/100 = 462000 10% of 1500 = 10 x 1500/100 = 150 Therefore, average unit sale price = 462000/150 = 3080.
