ratio 4 : 3, respectively. After 8 months, Amit withdrew 25% of his investment, whereas Rohit increased his investment by 50%. If at the end of 2 years, the profit earned by Amit was Rs. 20,000 more than that by Rohit, then find the total profit earned by the business.Solution
Let the amount invested by Amit and Rohit be Rs. ‘4x’ and Rs. ‘3x’, respectively. Ratio of profit shares: = {(4x × 8) + (4x × 3/4 × 16)} : {(3x × 8) + (3x × 3/2 × 16)} = (32x + 48x) : (24x + 72x) = 80x : 96x = 5 : 6 Let total profit = 11y ATQ: 6y - 5y = 20000 Or, y = 20000 Total profit = 11 × 20000 = Rs. 2,20,000
