8 : 9 : 5 10 : 9 : 12 8 : 9 : 12 4 : 9 : 12 |
8 : 9 : 12 |
Profit = Investment × time I : II : III Time ⇒ 3 : 4 : 5 Profit ⇒ 8 : 12 : 20 ---------------------------------------- Inv. ⇒ \(\frac{8}{3}\) : \(\frac{12}{4}\) : \(\frac{20}{5}\) = \(\frac{8}{3}\) : 3 : 4 = 8 : 9 : 12 [*Inv. Ratio = \(\frac{Profit\;ratio}{Time.\;ratio}\)] |
