Practicing Success
Three partners shared the profit in 9 : 8 : 10. They invested for 4 months, 6 months and 1 year. What was the ratio of their investments? |
81 : 48 : 30 60 : 48 : 81 81 : 48 : 60 48 : 60 : 81 |
81 : 48 : 30 |
Profit = Investment × time Inv. → x : y : z Time → 4 : 6 : 12 Profit → 9 : 8 : 10 x= \(\frac{9}{4}\) y = \(\frac{8}{6}\) = \(\frac{4}{3}\) z = \(\frac{10}{12}\) = \(\frac{5}{6}\) So, x : y : z = \(\frac{9}{4}\) : \(\frac{4}{3}\) : \(\frac{5}{6}\) = \(\frac{81\;:\;48\;:\;30}{36}\) x : y : z = 81 : 48: 30 |
