Question
‘A’ and ‘B’ started a business by investing Rs.
32000 and Rs. 30000, respectively. 12 months later, ‘C’ joined the business by investing Rs. 20000. After 6 more months, ‘B’ withdrew all of his capital. If at the end of second year, the total profit earned by them together is Rs. 25800, then find the profit earned by ‘B’ and ‘C’ together at the end of 2nd year.Solution
ATQ; Ratio of profit shares of ‘A’, ‘B’ and ‘C’ = (24 × 32000):(18 × 30000):(12 × 20000) = 64:45:20 Profit of ‘B’ and ‘C’ together = (25800) × {(45 + 20)/(64 + 45 + 20)} = Rs. 13000
