Question

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

विकल्प

• Rs. 45

• Rs. 50

• Rs 55

• Rs. 60

Answer 1

Rs. 60

Explanation:

(C.P. of 17 balls) – (S.P. of 17 balls) = (C.P. of 5 balls)

⇒ C.P. of 12 balls = S.P. of 17 balls = Rs. 720.

⇒ C.P. of 1 ball = Rs. `(720/12)` = Rs. 60.
