    Sakshi can do a piece of work in 20 days. Tanya is 25% more efficient than Sakshi. The number of days taken by Tanya to do the same piece of work is

    A) 15                                

    B) 16   

    C) 18                                

    D) 25

    Correct Answer: B

    Solution :

    Ratio of times taken by Sakshi and Tanya
    \[=125:100=5:4\]
    Suppose Tanya takes x days to do the work.
    \[5:4::20:x\]\[\Rightarrow \]\[x=\left( \frac{4\times 20}{5} \right)\]
    \[\Rightarrow \]   x = 16 days
    Hence, Tanya takes 16 days to complete the work.
