A grocer has a sale of Rs.6435, Rs.6927, Rs.6855, Rs.7230 and Rs.6562 for 5 consecutive months. How much sale must he have in the sixth month so that he gets an average sale of Rs.6500?

ARs.4991

BRs.5991

CRs.6001

DRs.6991

Answer:

A. Rs.4991

Read Explanation:

grocer will have a sale of Rs.X in the sixth month. ∴ Average = Rs.6500 ⇒ (6435 + 6927 + 6855 + 7230 + 6562 + X) ÷ 6 = 6500 ⇒ (6435 + 6927 + 6855 + 7230 + 6562 + X) = 6 × 6500 ⇒ X = 39000 – (6435 + 6927 + 6855 + 7230 + 6562) ⇒ X = Rs.4991
