Question
βAβ started a business by investing Rs. 1,200. Eight
months later, βBβ joined him by making an investment which is equal to 60% of the investment made by βAβ. If at the end of the year, total profit received by them is Rs. 4,200, then find the profit share of βBβ.Solution
ATQ,
A's investment = βΉ1200 for 12 months B's investment = 60% of βΉ1200 = βΉ720 for 4 months A's share = 1200 Γ 12 = 14,400 B's share = 720 Γ 4 = 2,880 Total share = 14,400 + 2,880 = 17,280 B's ratio = 2880 / 17280 = 1/6 B's profit = (1/6) Γ 4200 = βΉ700
