Two vessels P and Q contain 62.5% and 87.5% of alcohol respectively. If 12 litres from vessel P is mixed with 4 litres from vessel Q, the ratio of alcohol and water in the resulting mixture is?	Choose the correct option
A) 19:2  B) 18:3  C) 11:1  D) 11:5  E) 11:4
Quantity of alcohol in vessel P = 62.5/100 * 2 = 15/2 litres   Quantity of alcohol in vessel Q = 87.5/100 * 4 = 7/2 litres   Quantity of alcohol in the mixture formed = 15/2 + 7/2=
