Question
A factory produces two types of toys, A and B. The
production cost of toy A is ₹15 and for toy B is ₹25. If the total selling price of 500 toys is ₹11,400 and the ratio of toys A to B produced is 3:2, then find the profit percentage?Solution
Let the number of toys A = 3x and B = 2x. Total toys = 3x + 2x = 500 → 5x = 500 → x = 100. Toys A = 3x = 300. Total cost = 15(3x) + 25(2x) = 15(300) + 25(200) = 4500 + 5000 = 9500 Profit = 11,400 – 9500 = 1900 Profit percentage = 1900/ 9500 * 100 = 20% Answer: a) 20%.
