Discussion :: Time and Work
-
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:
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 =\(\left(\frac{4*20} { 5 }\right)\)
x = 16 days.
Hence, Tanya takes 16 days to complete the work.
