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 = [ - 5 * C.P]
Formula = 17*(S.P - C.P) [ for selling 17 balls].
17S.P = (17-5) C.P.
720/12 = C.P.
C.P = 60.
Formula = 17*(S.P - C.P) [ for selling 17 balls].
17S.P = (17-5) C.P.
720/12 = C.P.
C.P = 60.

Simply we can say that;
CP for 1 ball=x,
CP for 17 ball=17x,
SP for 17 ball=720.
Loss= CP - SP.
5x(overall)=17x-720,
X=60 price for each ball.
CP for 1 ball=x,
CP for 17 ball=17x,
SP for 17 ball=720.
Loss= CP - SP.
5x(overall)=17x-720,
X=60 price for each ball.

We can also solve it as:
Let the CP of 1 ball be x. then,
CP of 17 balls will be 17x.
Given that: loss=CP of 5 balls i.e. 5x.
Therefore, CP-SP=loss =>17x-720=5x=>x=Rs 60.
Let the CP of 1 ball be x. then,
CP of 17 balls will be 17x.
Given that: loss=CP of 5 balls i.e. 5x.
Therefore, CP-SP=loss =>17x-720=5x=>x=Rs 60.

Consider CP of 1 ball is X.
For 17 balls, CP is 17X.
Loss = CP-SP.
i.e;17X - 720.
Loss = 5X.
5X = 17X-720,
12X = 720,
X = 60.
For 17 balls, CP is 17X.
Loss = CP-SP.
i.e;17X - 720.
Loss = 5X.
5X = 17X-720,
12X = 720,
X = 60.

17(cp-720) = 5cp,
cp = 60.
cp = 60.
