Question

A grocer has a sale of 7435 rs., 5927 rs., 6825 rs., 7420 rs., 6562 rs., for five consecutive months how much more sale should happen in six month to make average sale of rs. 6500

Answer 1

Let required sale be x.
According to the question,
(7425+5927+6825+7420+6562+x)/6=6500
or, (34159+x)/6=6500
or, 34159+x=39000
or, x=39000-34159
or, x=4841
Thus, required sale in 6th month is ₹4841.

Answer 2

Answer:

Sixth months sale is RS.4,831

Step-by-step explanation:

Given:

Average sale of 6 months = Rs. 6,500

Let sale of sixth month = Rs. X

Total sale of 5 months = 7435 +5927 +6825 + 7420 +6562= 34,169

As we know that ,

Average sales = total sales  / no. of months

       6500 = (34,169 + X) /6

      6500 ×6 = 34,169 +X

       39000- 34169=X

        4831 = X
