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?

30.5

Average number of books sold = \(\frac{232 + 262 + 297 + 313 + 328 + 332 + 365 + 389 + 413 + 433 + 457 + 481 }{12}\)

= \(\frac{ 4302}{12}\)

= 358.5

Number of books sold in M8 = 389

Required difference = 389 - 358.5 = 30.5
