Question
In a mixture, 25% is water and the remainder is milk.
The milk is 140 liters more than the water. How much water is in the mixture?Solution
ATQ Let the total quantity of mixture be '100x' litres. So, quantity of water = 100x × 0.25 = '25x' litres And quantity of milk = 100x - 25x = '75x' litres ATQ: 75x - 25x = 140 Or, 50x = 140 So, x = 2.8 So, quantity of water present in the mixture = 25x = 2.8 × 25 = 70 litres
