If the selling price of 10 oranges is equal to the cost price of 13 oranges, then the profit percentage is:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 30%
Take the cost price of one orange as Rs 1. The money received for 10 oranges is then the cost of 13 oranges, so the profit on 10 oranges is the cost of 3 oranges.
Cost price of 10 oranges \(=\) Rs 10
Selling price of 10 oranges \(=\) cost price of 13 oranges \(=\) Rs 13
Profit \(=13-10=\) Rs 3
Profit per cent \(\displaystyle =\frac{3}{10}\times100=30\)%
The profit is 30%.
