- $ 800
Correct Option: D
Given in question , S.P. of fan = $ 600
| C.P. of fan = $ | ![]() | ![]() | ||||
| 90 |
| ∴ Required S.P. = | × | = $ 800 | 90 | 100 |
We can find required answer with the help of given formula :
| C.P. = S P | ![]() | ![]() | ||||
| 100 - Loss% |
| C.P. = | 100 - 10 |
| C.P. = | 90 |
| C.P. = | 9 |
| New S.P. = C.P. × | ![]() | ![]() | ||||
| 100 |
| New S.P. = | 6000 | ![]() | 100 + 20 | ![]() | ||||
| 9 | 100 |
| New S.P. = | = $ 800 | 9 |
