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...

(6535+6927+6855+7230+x)/6 = 6500.
34009+x = 6500*6.
34009+x = 39000.
x = 39000-34009.
x = 4991.
i.e., RS.4991/-.
34009+x = 6500*6.
34009+x = 39000.
x = 39000-34009.
x = 4991.
i.e., RS.4991/-.

Solution;
6435+6927+ 6855+ 7230 + 6562+x(let)/6=6500,
34009+x/6=6500,
34009+x=6500*6.
x=39000-34009=4991.
6435+6927+ 6855+ 7230 + 6562+x(let)/6=6500,
34009+x/6=6500,
34009+x=6500*6.
x=39000-34009=4991.

Hi friends please use this shortcut (6435+6927+6855+7230+6562+x)/6 = 6500.
34009+x = 32500.
x = 4991.
34009+x = 32500.
x = 4991.

Simple way.
(6500*6) = 34009+x.
Then
X = Rs.4991.
Where x= sale in rupees for the sixth month.
(6500*6) = 34009+x.
Then
X = Rs.4991.
Where x= sale in rupees for the sixth month.

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

6435+65=6500
6927-427=6500
6855-355=6500
7230-730=6500
6562-62=6500
How this happen?
6927-427=6500
