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 |

17 balls selling we get 720.
Good.but loss is there, we don't know. It was given that out of 5 balls equals to loss c.p. i.e subtract 17 from 5 = 12, I want c.p of each ball so, 720/12 = 60.

Here the cost price we have got 60 and its selling price is also 60. So how loss is possible?

Here we found Loss.
So Equation is Loss = CP - SP (but in case of profit -> Profit = SP - CP).
Loss (CP of 5 balls) = CP (CP of 17 balls) - SP (SP of 17 balls).
(Cost of 1 Ball) * 5 = 17 - 720.
(Cost of 1 Ball) * 5 - 17 = - 720.
(Cost of 1 Ball) - 12=- 720 =720/12 =60.
So, Cost of 1 ball is Rs. 60.

Loss (CP of 5 balls) = CP (CP of 17 balls) - SP (SP of 17 balls).

(Cost of 1 Ball) * 5 - 17 = - 720.
(Cost of 1 Ball) - 12=- 720 =720/12 =60.
So, Cost of 1 ball is Rs. 60.

Can anyone tell me the short tricks to find the answer to this question?

C.P of 17 balls = x.
Loss = C.P of 5 balls.
1 ball C.P is x/17.
5 balls C.P is 5x/17.
Loss = 5x/17.
17 balls C.P = 17 balls S.P+Loss.
x = 720+5x/17.
12x = 720*17.
x = 60*17.
Then each ball price is (x/17) = ((60*17)/17) = 60.
Loss = C.P of 5 balls.
1 ball C.P is x/17.
5 balls C.P is 5x/17.
Loss = 5x/17.
17 balls C.P = 17 balls S.P+Loss.
x = 720+5x/17.
12x = 720*17.
x = 60*17.
Then each ball price is (x/17) = ((60*17)/17) = 60.
