Question #2
A man buys goods worth Rs. 6000. He sells one-third of them at a 10% profit. At what profit percentage must he sell the remaining goods to achieve an overall profit of 20%?
A. 30%
B. 20%
C. 35%
D. 25%

Correct Answer: Option D


Explanation:
Total Cost Price = 6000. Desired Selling Price for 20% profit = 6000 * 1.20 = 7200. Cost Price of one-third = 2000. Selling Price of this part = 2000 * 1.10 = 2200. Remaining Cost Price = 4000. Required Selling Price for remaining = 7200 - 2200 = 5000. Profit on remaining = 5000 - 4000 = 1000. Profit percentage = (1000 / 4000) * 100 = 25%.
