Question

If the average sales per year from 1991 to 1994 was double the sales in 1990 and the domestic production in 1990 was 15% more than the average production from 1991 to 1994. The percentage excess of domestic production over sales in 1990 was closest to

• A. 47%
• B. 58%
• C. 142%
• D. 87%

Answer 1

The correct option is C

142%

Average sales from 1991 to 1994 $=\frac{875}{4}=218.75$

Thus, sales in 1990 = 109.375

Now, average production from 1991 to 1994= 230

Production in 1990=15% more= 264.5 approximately

Thus, percentage excess of domestic production over sales = 264-109 = 155

There percentage excess over 1990's sales $=\left(\frac{155}{110}\right)\times 100=142.2\%$
