According to the chart above, the average (arithmetic mean) revenue per week per product category is $128. However, there is an error in the chart; the revenue for Pens is actually $176, not $164. What is the new, correct average revenue per week per product category?

(A) $130
(B) $131
(C) $132
(D) $164
(E) $176


Given average revenue per week=$128
Error difference=$176-$164=$12

This difference of $12 is distributed among 4 categories given in the grid. So, each category belongs to 12/4=$3.

So, correct average=128+3=$131

Ans. (B)

It is a very basic level question.

176-164=12, which can be divided among 4 products.

3 will be added to each product, thereby the average increases from 128 to 131.
