Mark (✓) against the correct answer
On selling a racket for Rs 198, a shopkeeper gains 10%. The cost price of the racket is

(a) Rs 180
(b) Rs 178.20
(c) Rs 217.80
(d) Rs 212.50

Answer 1

(a) Rs. 180

SP of the racket = Rs. 198
Gain% = 10

$$\begin{gathered} \mathrm{CP}\mathrm{of}\mathrm{the}\mathrm{r}\mathrm{acket}=\{\frac{100}{(100+\mathrm{Gain}\%)}\times 100\} \\ =\{\frac{100}{(100+10)}\times 198\} \\ =\frac{100}{110}\times 198 \\ =\mathrm{Rs}.180 \end{gathered}$$
