    Answer : Option B

    Explanation :

    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     x = 1-sym-oparen-h1 4 x 20 1-sym-cparen-h1
    5

     x = 16 days.

    Hence, Tanya takes 16 days to complete the work.
