Two vessels A and B contain 62.5% and 87.5% of milk respectively. If 2 litres from vessel A is mixed with 4 litres from vessel B, the ratio of milk and water in the resulting mixture is:
19:5
Quantity of milk in vessel A = 62.5100×2 = 54 litres
Quantity of milk in vessel B = 87.5100×4=72 litres
Quantity of milk in the mixture formed = 54+72=194=4.75litres
As 6 litres of mixture is formed, ratio of milk and water in the mixture formed = 4.75 : 1.25 = 19 : 5.
