    In a mixture of 45 L, the ratio of milk to water is 3 : 2. How much water must be added to make the ratio 9:11?

    A)  10 L                            

    B)        24 L                            

    C)                    17 L                

    D)                    20 L

    Correct Answer: B

    Solution :

    Let,    \[M=3K,\,\,W=2K\] \[\therefore \]      \[3K+2K=45\Rightarrow K=9\] \[\Rightarrow \]   Milk = 27 L and water = 18 L Now, suppose x L of water is added to the mixture, such that \[\frac{27}{18+x}=\frac{9}{11}\,\,\Rightarrow \,\,162+9x=297\] \[\Rightarrow \]   \[9x=135\,\,\Rightarrow \,\,x=150\]
