Question

A man sold a radio-set for Rs. $250$ and gained one-ninth of its cost price. Find its cost price

• A. Rs. $215$
• B. Rs. $225$
• C. Rs. $235$
• D. Rs. $245$

Answer 1

Answer: (B)

Rs. $225$

Given, S.P. $=$ Rs. $250$
Gain $=\frac{1}{9}\times \text{C.P.}$
$\Rightarrow$ S.P. $-$ C.P. $=\frac{1}{9}\times \text{C.P.}$
$\Rightarrow \frac{10}{9}\times \text{C.P.}=$ Rs. $250$
$\Rightarrow \text{C.P.}=$ Rs. $225$
