By selling an article for $ 69, there is a loss of 8%, when the article is sold for $ 78, the gain or loss percent is :
-
- neither loss nor gain
- 4% gain
- 4% loss
- 40% gain
Correct Option: B
Given in question , SP of article = $ 69
Loss % = 8%
| ∴ CP = $ | = $ 75 | 92 |
New SP = $ 78
Gain = New SP - CP = 78 - 75 = $ 3
| ∴ Gain % = | × 100 | CP |
| Gain % = | × 100 = 4% | 75 |
We can find required answer with the help of given formula :
| C.P. = S P × | 100 - Loss% |
| C.P. = | 100 - 8 |
| = | = Rs. 75 | 92 |
| New S.P.= C.P |  | 100 + Profit% |  | |||
| 100 |
| 78 = 75 × | | 100 + Profit% | | |||
| 100 |
7800 = 7500 + 75 Profit%
⇒ 7800 - 7500 = 75 Profit% ⇒ 75 Profit% = 300
| Profit% = | = 4% | 75 |
