A man buys a product for Rs. 240 and sells it for Rs. 300. What is the profit percentage? MCQ with Answer and Explanation

Explanation:
Let CP of 1 = 1, CP of 12 = 12, SP of 9 = 12 => SP of 1 = 12/9 = 4/3 = 1.333, gain=33.33%.

Explanation:
Let Cost Price = 100x. Marked Price = 140x. Selling Price = 140x * 0.80 = 112x. Profit = 12x. 12x = 48. x = 4. Cost Price = 100 * 4 = 400.

Explanation:
Cost of 5 kg mixture = (2 * 50) + (3 * 60) = 100 + 180 = 280. Cost per kg = 280 / 5 = 56. Selling Price = 67.20. Profit = 11.20. Profit percentage = (11.20 / 56) * 100 = 20%.
