Hello friends solve this question

Answer 1

hello my friend !

so sumit can do a work in 20 days
work done by him in one day = 1/20

now since raghav is 20% more efficient he can do 20% more work in a same day

work done by raghav in one day = 1/20 + 20/100 ×1/20 =6/100

so raghav can finish it in. 100/6 = 16.66 days
