Practicing Success
A, B and C are partners in a business. A whose money has been used for 2 months, claims \(\frac{1}{8}\) of the profit, B whose money has been used for 3 months, claims \(\frac{1}{4}\) of the profit. C had invested Rs. 2630 for 5 months. How much money did A contribute? |
Rs. 1841 Rs. 1578 Rs. 1315 Rs.1052 |
Rs. 1315 |
For \(\frac{1}{8}\) and \(\frac{1}{4}\) Let Total profit = 8 unit Hence, Profit of A = 8 × \(\frac{1}{8}\) = 1 Profit of B = 8 × \(\frac{1}{4}\) = 2 Profit of C = 8 - (1 + 2) = 5 Now, A : B : C Profit : 1 : 2 : 5 Time : 2 : 3 : 5 Inv. : \(\frac{1}{2}\) : \(\frac{2}{3}\) : 1 [Inv. ratio = \(\frac{Profit.\;Ratio}{Time\;Ratio}\)] : 3 : 4 : 6 ATQ, C invest = 6R = 2630 1R = \(\frac{2630}{6}\) A's investment = \(\frac{2630}{6}\) × 3 = Rs.1315 |
