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.

Avg=(6435+6927+6855+7230+6565+x)/6=6500
=(34012+x)=6*6500
x=39000-34012=4988 from this can select nearest ans...

At First, Multiply 6500x6=39000 (bcoz avg is asking in Q)
Then, add all the 5 sale i.e 34009,
Deduct 39000 from the total sale i.e.34009, it becomes 4991.

6435+6927+6855+7230+6562= 34009
6500*7 =39000
39000-34009 =4991
6500*7 =39000
39000-34009 =4991

Why do we multiply 6 with 6500.

Hi friends...
Here is the shortcut method to find this problem...
given average sale for 6 months is 6500..
but we don't know 6 month reading...let it be x..
now,according to the formula...
(6435+6927+6855+7230+6562+x) /6 = 6500
34009 + x = 39000
x = 4991.
