Question
‘A’ and ‘B’ entered into a partnership by
investing Rs. 7200 and Rs. 3600, respectively. If ‘A’ invested his sum for only 5 months and the total annual profit earned by them together is Rs. 12100, then find the total profit earned by ‘B’.Solution
Ratio of profit share of ‘A’ and ‘B’ = (7200 × 5):(3600 × 12) = 5:6 Total profit earned by ‘B’ = (6/11) × 12100 = Rs. 6600
