100 oranges are bought for $ 350 and sold at the rate of 48 per dozen. The percentage of profit or loss is :
-
- 15% loss
- 15% gain
-
14 2 % loss 7 -
14 2 % profit 7
Correct Option: D
Given in question , C.P. of 100 oranges = $ 350
S.P. of 12 oranges = $ 48
| ∴ S.P. of 100 oranges = | × 100 = $ 400 | 12 |
Profit = S.P. - C.P. = $ (400 – 350) = $ 50
| ∴ profit % = | × 100 = | % | 350 | 7 |
| profit % = 14 | % | 7 |
We can find required answer with the help of given formula :
Here, a = 100, p = 350
| b = 100, q = | × 100 = 400 | 12 |
| Gain % = |  | aq - bp |  | × 100% | |
| bp |
| Gain % = | × 100% | 100 × 350 |
| Gain % = | × 100% | 35 |
| Gain % = | % = 14 | % | 7 | 7 |
