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.

Add all 5 consecutive nos (6435 + 6927 + 6855 + 7230 + 6562) = 34009.
Sales for six months = (6500 * 6) = 39000.
At six months Rs = (39000-34009) = Rs. 4991.
Sales for six months = (6500 * 6) = 39000.
At six months Rs = (39000-34009) = Rs. 4991.

Add all the values for 5 consecutive months which is equal to Rs. 34009.
Required sale is for six months is(6 * 6500) = 39000.
39000 - 34009 = 4991.
Therefore it's Rs. 4991.

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 months reading.
Let it be x.
Now, According to the formula.
(6435+6927+6855+7230+6562+x)/6 = 6500
34009 + x = 39000.
x = 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.

An easy way for this type of problem is;
Here, we have to find 6th month RS?
To find,
Solution:
(Add all 5 month Rs. + 6 th month RS.)/6= 6500,
i.e (34009+ 6th month Rs.)|6 =6500,
34009 + 6th month Rs. = 6500 * 6,
6th month Rs. = 39000 - 34009,
Ans 6th month RS. = 4991.

Difference between 6500 from each is 65,-427,-355,-730,-62.
Add the following:
= 65 - 427 - 355 - 730 - 62,
= -1509,
Subtract from 6500.
6500 - 1509 = 4991.
Add the following:
= 65 - 427 - 355 - 730 - 62,
= -1509,
Subtract from 6500.
6500 - 1509 = 4991.
