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:
Answer: Option
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 |  |
= Rs. 60. |
| 12 |

Loss = CP-SP
Acc to the ques
SP is given for 17 balls i.e 720
So SP of 1 ball = 720/12
let cp of 1 ball = x
loss = 5x (loss equals to the cp of 5 balls)
5x/17=x-720/17(loss for 17 balls)
5x/17 = (17x-720)/17
5x=17x-720
12x = 720
x=720/12
x=60

12x = 720
x=720/12
x=60

Why it cann't be solved like this:
Loss = CP-SP
Acc to the ques
SP is given for 17 balls i.e 720
So SP of 1 ball = 720/12
let cp of 1 ball = x
loss = 5x (loss equals to the cp of 5 balls)
5x=x-720/17
5x = 17x-720/17
5x-17x= 720/17
12x = 720/17
x=???
Loss = CP-SP

SP of 17 balls will be subtracted CP of 5 balls. Because there is a loss equal to 5 balls in selling of 17 balls.

More easy: 17-5 = 12.
And 720/12 = 60.
And 720/12 = 60.
