STEP-BY-STEP
Aravind = 24 days so 1 day work =1/24
Mani= 36 days so 1 day work = 1/36
Let Hari can alone do in x days so 1 day work = 1/x
All working together= 1/24+1/36+1/x= 1/8 can complete the work in 8 days
Solving the equation we get x= 18 days.
Mani= 36 days so 1 day work = 1/36
Let Hari can alone do in x days so 1 day work = 1/x
All working together= 1/24+1/36+1/x= 1/8 can complete the work in 8 days
Solving the equation we get x= 18 days.
