Question: A, B and C jointly thought of engaging themselves in a business venture. It was agreed that A would invest Tk. 6500 for 6 months, B, Tk. 8400 for 5 months and C, Tk. 10,000 for 3 months. A wants to be the working member for which, he was to receive 5% of the profits. The profit earned was Tk. 7400. Calculate the share of B in the profit.Solution:For managing, A received = 5% of Tk. 7400 = Tk. 370.Balance = Tk. (7400 - 370) = Tk. 7030.Ratio of their investments = (6500 × 6) : (8400 × 5) : (10000 × 3)= 39000 : 42000 : 30000= 13 : 14 : 10∴ B's share = Tk. 7030 × (14/37) = Tk. 2660
