Two vessels P and Q contain 62.5% and 87.5% of alcohol respectively. If 2 litres from vessel P is mixed with 8 litres from vessel Q, the ratio of alcohol and water in the resulting mixture is? Select the correct option: A) 33:1 B) 33:7 C) 33:8 D) 33:5 E) 33:2
Quantity of alcohol in vessel P = 62.5/100 * 2 = 5/4 litres   Quantity of alcohol in vessel Q = 87.5/100 * 4 = 7/1 litres   Quantity of alcohol in the mixture formed = 5/4 + 7/1 = 33/4=

<output>33/4 = around 8.25</output>
8.25 litres   As 10 litres of mixture is formed, ratio of alcohol and water in the mixture formed= 8.25 : 1.75 = 33:7.   Answer: 33:7
