Question

A shopkeeper allows a discount of $10\%$ on a watch whose marked price is Rs. $3400$ and in the process makes a gain of Rs. $220$. What is the cost price of the watch?

• A. Rs. $2340$
• B. Rs. $2540$
• C. Rs. $2840$
• D. Rs. $2440$

Answer 1

Answer: (C)

Rs. $2840$

S.P. of the watch $=\frac{3400\times (100-10)}{100}=$ Rs. $3060$.

Gain $=$ Rs. $220$

Therefore, C.P. of the watch $=$ Rs. $(3060-220)=2840$.

Hence. option C is the correct answer.
