Cost price of 100 books is equal to the selling price of 60 books. The gain percentage/loss percentage is
-
-
66 3 % 2
- 67%
- 66%
-
66 2 % 3
-
Correct Option: D
Let C.P. of each book = Re. 1
∴ C.P. of 60 books = Rs. 60
S.P. of 60 books = Rs. 100
Gain = S.P. of 60 books - C.P. of 60 books = 100 - 60 = Rs 40
| ∴ Gain percent = | × 100 | C.P. of 60 books |
| Gain percent = | × 100 | 60 |
| Gain percent = | = 66 | % | 3 | 3 |
Second method to solve this question :
Here, p = 100, q = 60
| Gain % = |  |  | × 100 | ||
| q |
| Gain % = | | | × 100 | ||
| 60 |
| Gain % = | = 66 | % | 3 | 3 |
