A and B invested a sum of money in the ratio of 3 : 5. After a few months, A withdrew and collected back his money. At the end of the year, they received profit in the ratio of 2 : 5. After how many months A withdrew his money? |
4 1 8 9 |
8 |
A : B Inv. ratio → 3 : 5 Time → t : 12 Profit → 2 : 5 (given) Here, (Profit = Inv. × time) ⇒ \(\frac{2}{5}\) = \(\frac{3\;×\;t}{5\;×\;12}\) ⇒ 3 t = 24 ⇒ t = 8 Hence, A invest his capital for 8 months, So, A withdrew after = 8 Months |
