A fruit-seller buys some oranges and by selling 40% of them he realises the cost price of all the oranges. As the oranges being to grow over-ripe, he reduces the price and sells 80% of the remaining oranges at half the previous rate of profit. The rest of the oranges being rotten are thrown away. The overall percentage of profit is
-
- 80
- 84
- 94
- 96
Correct Option: B
Let Number of oranges bought = 100
And C.P. of oranges = $ 100
S.P of 40 oranges = $ 100
Gain on 40 Oranges = 100 - 40 = $ 60
| ∴ Gain percent = | × 100 = 150 % | 40 |
Remaining oranges = 60
| Their 80 % = | = 48 | 100 |
These are sold at a profit of 75 % .
| ∴ Their S.P. = | = $ 84 | 100 |
12 oranges was rotten so he threw away.
∴ Total SP = 100 + 84 = $ 184
Gain = Total SP - CP = 184 - 100 = $ 84
| ∴ Gain percent = | × 100 = 84% | 100 |
