Two vessels P and Q contain 62.5% and 87.5% of alcohol respectively. If 2 litres from vessel P is mixed with 6 litres from vessel Q, the ratio of alcohol and water in the resulting mixture is?	Choose the correct choice:
A) 13:1	B) 13:3	C) 13:8	D) 13:5	E) 13:2
Quantity of alcohol in vessel P = 62.5/100 * 2 = 5/4 litres   Quantity of alcohol in vessel Q = 87.5/100 * 6 = 21/4 litres   Quantity of alcohol in the mixture formed = 5/4 + 21/4 = 13/2=

<output>13/2 = around 6.5</output>
6.5 litres   As 8 litres of mixture is formed, ratio of alcohol and water in the mixture formed= 6.5 : 1.5 = 13:3.   Answer: 13:3
