By selling 3 dozen oranges for Rs. 405, a trader loses 25%. How many oranges should he sell for Rs. 288 if he needs to earn a profit of 20% in the transaction?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 16.
The selling price of 36 oranges = 405
So, the cost price of the 36 oranges = 405 × 100/75 = 540
For 20% profit, the selling price of 36 oranges = 540 × (120/100) = 648
So, the total number of oranges sell in Rs 288 = (36/648) × 288 = 16
