(b)₹ 6999.20
(c)₹ 6654
(d)₹ 7000
Answer
Answer (as printed): A
Explanation
Rebate $=6 \%$ of $₹ 6650=₹\left(\frac{6}{100} \times 6650\right)=₹ 399$. Sales tax $=10 \%$ of $₹(6650-399)=₹\left(\frac{10}{100} \times 6251\right)=₹ 625.10$. $$\text { ∴ } \text { Final amount }=₹(6251+625.10)=₹ 6876.10 .$$
