Rajeev buy goods worth Rs. 6650. He gets a rebate of 6% on it. After getting the rebate, he pays sale tax @ 10%. Find the amount he will have to pay for the goods ?

Answer: Option A

Rebate = 6% of Rs. 6650
$$\begin{array}{rl}& =\text{Rs}\text{. }\left(\frac{6}{100}\times 6650\right)\\ & =\text{Rs}\text{. 399}\end{array}$$
Sales tax = 10 % of (6650 - 399)
$$\begin{array}{rl}& =\text{Rs}\text{. }\left(\frac{10}{100}\times 6251\right)\\ & =\text{Rs}\text{. 625}\text{.10}\end{array}$$
∴ Final amount = Rs. (6251 + 625.10)
                         = Rs. 6876.10
