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
Correct Option: C
Let the CP of each ball = y.
Then, clearly the cost price of (17 – 5) balls = $ 720
i.e., 12y = 720
| ⇒ y = | = $ 60 | 12 |
Hence , the CP of each ball is $ 60 .
