Answer 1

Step-by-step explanation:

Let the selling of 6th month be ₹ x.

Hence

$Average \: selling \: of \: six \: months \\ = \frac{6435 + 6927 + 6855 + 7230 + 6562 + x}{6} \\\therefore \: 6500 = \frac{6435 + 6927 + 6855 + 7230 + 6562 + x}{6} \\ \therefore \: 6500 = \frac{34009 + x}{6} \\ \therefore \: 6500 \times 6= 34009 + x\\ \therefore \: 39000 = 34009 + x\\ \implies x = \: 39000 - 34009 \\ \implies \huge \fbox{x =4991}$

Thus the businessman should make a selling of ₹ 4991 in the sixth month to maintain the average selling of ₹ 6500.
