    Three glasses A, B and C contain mixture of water and alcohol in the ratio of2:3:4. The ratio of water and alcohol in these glasses are 1: 5, 3: 5, 5: 7 respectively. If the mixtures of the glasses are mixed together, then what will be their ratio in it?

    A) 7 : 19                           

    B) 1 : 2

    C) 25 : 47                         

    D) 67 : 91

    Correct Answer: C

    Solution :

    Suppose glasses A, B and C contains 2, 3 and 41 mixtures Total quantity of water =         \[\frac{1}{6}\times 2+\frac{3}{8}\times 3+\frac{5}{12}\times 4=\frac{25}{8}l\] Total quantity of alcohol =         \[\frac{5}{6}\times 2+\frac{5}{8}\times 3+\frac{7}{12}\times 4=\frac{47}{8}l\] \[\therefore \]      Required Ratio = \[\frac{25}{8}:\frac{47}{8}=\] 25: 47
