Question

By giving a discount of $10\%$ on the marked price of Rs. $1100$ of a cycle, a dealer gains $10\%$. The cost price of the cycle is

• A. Rs. $1100$
• B. Rs. $900$
• C. Rs. $1089$
• D. Rs. $891$

Answer 1

The correct option is B Rs. $900$

M.P. $=$ Rs. $1100$, discount $=10$ $\%$
$\therefore$ S.P. $=1100-10$ $\%$ of Rs. $1100$

$\Rightarrow 1100-110=$ Rs. $990$
Gain $=$ $10\%$
$\therefore$ C.P. $=$Rs. $\frac{990\times 100}{110}=$ Rs. $900$
