Quantity of milk remaining in vessel 'A' after 120 litres of milk is withdrawn = 480 - 120 = 360 litres Ratio of quantity of milk to that of water in vessel 'B' after 120 litres from vessel 'A' is mixed with it = 120:480 = 1:4 So, quantity of water remaining in vessel 'B' after 120 litres of mixture is withdrawn = 480 - {120 X (4/5)} = 384 litres And, quantity of milk in vessel 'A' after 120 litres of mixture is added = 360 + {120 X (1/5)} = 384 litres So, required ratio = 384:384 = 1:1
