Question

Find the M.P. of a watch whose S.P. is Rs. $510$ and the discount offered on it is $15$ $\%$?

• A. Rs. $800$
• B. Rs. $700$
• C. Rs. $600$
• D. Rs. $500$

Answer 1

The correct option is C Rs. $600$

S.P. $=510$

Discount $=15\%$

$\text{M.P.}=\frac{\text{S.P.}\times 100}{(100-\text{discount}\%)}$

$=$ Rs. $\frac{510\times 100}{(100-15)}$

$=$ Rs. $\frac{51000}{85}=$ Rs. $600$
