Question
Quantity of milk is 40% more than that of water in 240
litres mixture (milk + water). If 18 litres milk is added, then find the quantity of milk in the resultant mixture now.Solution
Let the initial quantity of water be 'y' litres.
Initial quantity of milk = '1.40y' litres
So, y + 1.40y = 240
Or, 2.40y = 240
Or, 'y' = 100 litres
Initial quantity of milk = 1.40 × 100 = 140 litres
Therefore, final quantity of milk = 140 + 18 = 158 litres
