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: |
₹45 ₹50 ₹60 ₹55 |
₹60 |
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 |
