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%.

Question #3
A trader marks his goods 50% above the cost price and gives a 20% discount. Furthermore, he uses a false weight of 900 grams instead of 1 kg. What is his actual overall profit percentage?
A. 30%
B. 25%
C. 40%
D. 33.33%

Correct Answer: Option D


Explanation:
Let the true Cost Price for 1000 grams be Rs. 1000. The trader gives only 900 grams, so his actual Cost Price is Rs. 900. He marks up 1000 grams to Rs. 1500 and gives a 20% discount. Selling Price = 1500 * 0.80 = Rs. 1200. Profit = 1200 - 900 = 300. Profit percentage = (300 / 900) * 100 = 33.33%.
