Answer 2

Answer:

20/9 day

Step-by-step explanation:

Arun do 1 work = 5 day

Then, work done in 1 day by Arun = 1/5

Now,

Ram do 1 work = 4 day

Then, work done in 1 day by Ram = 1/4

Therefore,, if he do work together,

work done 1 day by together = (work done in 1

day by Arun) +(work

done in 1 day by Ram)

= 1/5 + 1/4

= 9/20

Thus, 1 work do = 20/9 day
