On selling 33 balls at Rs.725, there is a loss equal to the cost price of 8 balls. The cost price of a ball is: |
Rs.20 Rs.39 Rs.29 Rs.30 |
Rs.29 |
Loss = C.P. - S.P. C.P. of 8 = C.P. of 33 - S.P. of 33 C.P. of 25 = S.P. of 33 Here, S.P. of 33 balls = Rs.725 (given) Therefore. C.P. of 25 balls = Rs. 725 C.P. of 1 ball = \(\frac{725}{25}\) = Rs.29 |
