    In a mixture of 75 L, the ratio of milk to water is 2: 1. The amount of water to be further added to the mixture so as to make the ratio of the milk to water 1 : 2 will be

    A) 45 L                             

    B) 60 L

    C) 75 L                 

    D) 80 L

    Correct Answer: C

    Solution :

    In 75 L of the mixture, Milk \[=\frac{2}{3}\times 75=50\,L\] Water \[=\frac{1}{3}\times 75=25\,L\] Let x L of water be added. Then,             \[\frac{50}{x+25}=\frac{1}{2}\] \[\Rightarrow \]   \[x+25=100\] \[\Rightarrow \]   \[x=75\,L\]
