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?
Answer: Option
Explanation:
Total sale for 5 months = Rs. (6435 + 6927 + 6855 + 7230 + 6562) = Rs. 34009.
Required sale = Rs. [ (6500 x 6) - 34009 ]
= Rs. (39000 - 34009)
= Rs. 4991.

Assume that, 6th month is x.
6500 = (6435+6927+6855+7230+6562+x)/6.
So, x = 4991.
6500 = (6435+6927+6855+7230+6562+x)/6.
So, x = 4991.

(6435+6927+6855+7230+6562+y)/6=6500
34009+y=6500*6
Y=39000-34009
Y=4991
34009+y=6500*6
Y=39000-34009
Y=4991
