Priya can do a work in 16 days. In how many days will the work be completed by Sai, if the efficiency of Sai is 60% more than that of Priya ?

Correct Answer: 10 days

Explanation:

Ratio of efficiencies of Priya and Sai is


Sai : Priya = 160 : 100 = 8 : 5


Given Priya completes the work in 16 days


Let number of days Sai completes the work be 'd'


=> 5×16 = 8×d


d = 10 days.


Therefore, number of days Sai completes the work is 10 days.
