On selling 17 balls at ₹720, there is a loss equal to the cost price of 5 balls. The cost price of a ball is:
Answer & explanation
Correct answer: option 3
Loss = C.P. - S.P.
C.P. of 5 = C.P. of 17 - S.P. of 17
C.P. of 12 = S.P. of 17
Here, S.P. of 17 balls = Rs.720 (given)
Therefore.
C.P. of 12 balls = Rs. 720
C.P. of 1 ball = \(\frac{720}{12}\) = Rs.60
