Days needed by alok = 20
Work done by him in 1 day = 1/20
Similarly
by shankar = 1/15
and by Harish = 1/10
let the days needed by all of them to complete the work be 'x'
When they work together
x ( 1/20 + 1/15 + 1/10 ) = 1
x ( 3/60 + 4/60 + 6/60 ) = 1
x ( 13/60 ) = 1
x = 1 * 60/13
x = 4 whole 8/13 days ( Mixed fraction )
They can Complete the work together in 4 whole 8/13 days .
