Question

On selling$17$balls at$\text{Rs. 720}$, there is a loss equal to the cost price of$5$balls. The cost price of a ball is:

• A. $45$
• B. $50$
• C. $55$
• D. $60$

Answer 1

The correct option is D

$60$

Loss occurred = cost of $5$balls

According to the question,

Cost price of$17$balls $-$ Selling price of$17$balls = Cost of$5$balls

Cost of$12$balls = Selling price of$17$balls = $\text{Rs. 720}$

Cost of$1$ball = $720÷12$

= $60$

Hence, the cost price of$1$is $\text{Rs. 60}$
