months later, ‘B’ joined him by making an investment which is equal to 60% of the investment made by ‘A’. If at the end of the year, total profit received by them is Rs. 4,200, then find the profit share of ‘B’.Solution
ATQ,
A's investment = ₹1200 for 12 months B's investment = 60% of ₹1200 = ₹720 for 4 months A's share = 1200 × 12 = 14,400 B's share = 720 × 4 = 2,880 Total share = 14,400 + 2,880 = 17,280 B's ratio = 2880 / 17280 = 1/6 B's profit = (1/6) × 4200 = ₹700
