Anil alone takes 2 hrs 40 mins to complete a work and Sumit alone can complete the same work in half time of Anil. How much time will be taken by Sumit to complete the work?
Answer & explanation
Correct answer: option 4
Time taken by Anil to complete the work = 2 hrs 40 mins = 160 mins
Time taken by Sumit to complete the same work = $\frac{1}{2}$ time taken by Aniil
= 80 mins
