'A' and 'B' started a business by investing Rs. 4,200
and Rs. 5,600, respectively. If 'A' and 'B' invested their investments for 7 months and 9 months, respectively, then find the profit share of 'B' out of the total profit earned by them which is Rs. 3,900.Solution
ATQ, Ratio of profit shares of 'A' and 'B' = (4,200 X 7):(5,600 X 9) = 29,400:50,400 = 49:84 So, profit share of 'B' = 3,900 X (84/133) = Rs. 2,463
