A 10 Liter Mixture Of Milk And Water Contains 30 Percent Water. Two Liters Of This Mixture Is Taken Away. How Many Liters Of Water Should Now Be Added So That The Amount Of Milk In The Mixture Is Double That Of Water ? |

Answer» TWO liters were taken AWAY So we have the only 8L of the mixture. Amount of MILK in 8 L of mixture = 8 * 70% = 5.6 liters Amount of WATER in 8 L of mix = (8 - 5.6) = 2.4 L. HALF of milk i.e half of 5.6 = 2.8 L. We need (2.8 - 2.4)L water more = 0.4 L Two liters were taken away So we have the only 8L of the mixture.
