Answer 2

Given average = Rs. 6500

And sales are Rs. 6435, Rs. 6927, Rs. 6855, Rs. 7230 and Rs. 6562 for 5 consecutive months.

Let the sale of 6th month be x

Then, 
                   6500 = (x+6435+ 6927+6855+7230+6562 )/6
                   39000 = x + 34009
                   x = 4991

Therefore, sale at 6th month = Rs. 4991.
