A man buys orange at 18 for. ₹135 sells then at 11 for ₹90. How many oranges must he sell to gain ₹150?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 220.
Cost price of 1 orange = 135/18 = 7.5
Selling price of 1 orange = 90/11 = 8.18
Profit per orange = 8.18 - 7.5 = 0.68
Number of oranges sold to gain 150 = 150/0.68
⇒ 220 (nearest)
