Question 74

The Bar graph given below presents the number of books sold by a bookseller during different months of a year.

The number of books sold in month M8 is how much more than the average number of books sold per month?

Solution

The number of books sold in month M8 = 389

the average number of books sold per month = $$\frac{232+262+297+313+328+332+365+389+413+433+457+481}{12}$$

= $$\frac{4302}{12}$$

= 358.5

Difference = 389-358.5

= 30.5

The number of books sold in month M8 is 30.5 more than the average number of books sold per month.
