    'The ratio of the quantities of an acid and water in a mixture is 1: 3. If 5 L of acid is further added to the mixture, the new ratio becomes 1: 2. The quantity of new mixture in litres is

    A) 32                                

    B) 40

    C) 42                                

    D) 45

    Correct Answer: D

    Solution :

    Let the quantity of add in original mixture be x L and that of water be 3x L. \[\therefore \]      \[\frac{x+5}{3x}=\frac{1}{2}\] \[\Rightarrow \]   \[2x+10=3x\] \[\Rightarrow \] \[x=10\] \[\therefore \] Quantity of new mixture             \[=4x+5=45\,L\]
