    A milk vendor bought 28 L of milk at the cost of Rs. 8.50/L. After adding some water, he sold the mixture at the same price. If he gains 12.5%, how much water did he add?

    A) 5.5 L                

    B) 4.5 L

    C) 3.5 L    

    D) 2.5 L

    Correct Answer: C

    Solution :

    Total CP of milk \[=28\times 8.50\] \[=Rs.\,238\] \[\therefore \]      Profit \[=12.5%\text{ of }238\]             \[=\frac{12.5}{100}\times 238=29.75\] Let he added x L of water \[\therefore \]      Profit \[=x\times 8.5\] \[\Rightarrow \] \[29.75=x\times 8.5\] \[\Rightarrow \] \[x=3.5\,L\]
