Two vessels P and Q contain 62.5% and 87.5% of alcohol respectively. If 4 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) 3:1 B) 19:4 C) 19:8 D) 19:5 E) 19:2
Quantity of alcohol in vessel P = 62.5/100 * 4 = 5/2 litres   Quantity of alcohol in vessel Q = 87.5/100 * 4 = 7/2 litres   Quantity of alcohol in the mixture formed = 5/2 + 7/2=
