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?
Answer & explanation
Correct answer: option 1
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
