Question
Quantity of milk is 33% more than that of water in 233
litres mixture (milk + water). If 27 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 = '1.33y' litres
So, y + 1.33y = 233
Or, 2.33y = 233
Or, 'y' = 100 litres
Initial quantity of milk = 1.33 Γ 100 = 133 litres
Therefore, final quantity of milk = 133 + 27 = 160 litres
