A, B and C started a business by investing Rs 1, 00,000 in all. C invested Rs 10,000 more than B and B invested Rs 15,000 more than A, if the total profit is Rs 60,000, then what is the share of B in the profit?

Let the investment of A be Rs. x Then, investment of B = Rs. (x + 15,000) Investment of C = Rs. (x + 15,000 + 10,000) = Rs. (x + 25,000) According to the question, x + (x + 15,000) + (x + 25,000) = 1,00,000 Or, 3x + 40,000 = 1,00,000 Or, 3x = 60,000 Or, x = 20,000 So, Investment of A = Rs. 20,000 Investment of B = Rs. 35,000 Investment of C = Rs. 45,000 Ratio of investments of A, B and C = 20,000 : 35,000 : 45,000 = 4 : 7 : 9 Total profit = Rs. 60,000 Share of B in the profit = (7/20) × 60,000 = Rs. 21,000 Therefore, the share of B in the profit is Rs. 21,000.
