A sells a scooter priced at ₹ 36000. He gives a discount of 8\% on the first ₹ 20000 and 5\% on the next ₹ 10000. How much discount can he afford on the remaining ₹ 6000 if he is to get as much as when 7\% discount is allowed on the total?
(a)5\%
(b)6\%
(c)7\%
(d)8\%
Answer
Answer (as printed): C
Explanation
Let the discount on ₹ 6000 be $x \%$. Then, $(100-x) \%$ of 6000 $$\begin{aligned} & =93 \% \text { of } 36000-(92 \% \text { of } 20000+95 \% \text { of } 10000) \\ & =33480-(18400+9500)=5580 . \\ & \Rightarrow(100-x)=\frac{5580 \times 100}{6000}=93 \\ & \Rightarrow x=7 . \end{aligned}$$
