A radio is sold for $ 990 at a profit of 10%. What would have been the actual profit or loss on it, had it been sold for Rs. 890?
-
- $ 10 loss
- $ 10 profit
- $ 90 loss
- $ 90 profit
Correct Option: A
Here , Selling price of radio ( S.P. ) = $ 990 and profit = 10%
| C.P. of radio = | × S.P. of radio | 100 + profit% |
| C.P. of radio = | × 990 = $ 900 | 110 |
Second SP = $ 890
∴ Loss = 900 – 890 = $ 10
We can find required answer with the help of given formula :
| C.P. = S.P. |  |  | ||||
| 100 + Profit% |
| C.P. = 900 | | | ||||
| 100 + 10 |
| C.P. = | = 900 | 110 |
Loss = C.P. – S.P. = 900 – 890 = $ 10
