Question
Three partners ‘A’, ‘B’ and ‘C’ started a
business by investing in the ratio 4:5:7 respectively and the ratio of time for which they made their investments is 3:4:9, respectively. If the profit share of ‘C’ is Rs. 6300, then what is the total profit earned by all of them together?Solution
Ratio of profit shares of ‘A’, ‘B’ and ‘C’ respectively = (4 × 3):(5 × 4):(7 × 9) = 12:20:63 Required profit = {(12 + 20 + 63)/63} × 6300 = Rs. 9500
