C Correct answer
Explanation

Cost of 50L = 50 * 236 = 11800. Let x be liters of duplicate oil. Total cost = 11800 + 180x. Total quantity = 50 + x. Total revenue = 250 * (50 + x). Profit = Revenue - Cost = 250(50+x) - (11800 + 180x) = 12500 + 250x - 11800 - 180x = 700 + 70x. We want profit >= 2100. 700 + 70x = 2100. 70x = 1400. x = 20.

Let SP be the selling price. Trader 1 profit = 0.2 * CP1 = 0.2 * (SP / 1.2) = SP / 6. Trader 2 profit = 0.2 * SP. Difference = 0.2 * SP - SP / 6 = 85. (1.2 * SP - SP) / 6 = 85. 0.2 * SP = 510. SP = 2550.

Let cost price be 100. Marked price = 120. Discount = 10% of 120 = 12. Selling price = 120 - 12 = 108. Profit = 108 - 100 = 8%.

B Correct answer
Explanation

Total cost = 120 * 3 = 360. 1/3 sold (40 books) at 4 each = 160. Half sold (60 books) at 5 each = 300. Remaining (20 books) at cost (3 each) = 60. Total revenue = 160 + 300 + 60 = 520. Profit = 520 - 360 = 160. Profit % = (160 / 360) * 100 = 1600 / 36 = 400 / 9 = 44 4/9%.

The merchant uses 900g instead of 1000g. Profit = 100g. Profit percentage = (Profit / Actual weight sold) * 100 = (100 / 900) * 100 = 100/9 = 11 1/9%.
