Answer:
one day of tomba that finish the work = 1/20 day
one day of Choba finish the work =1/30 day
total work that done by both Tomba and Choba = 1/20+1/30
=3+2/60
=5/60=1/12 day
remaining work = 1/10 - 1/12
=6 - 5/60
=1/60
Yama finish the whole work = 1÷1/60 =
1×60/1
Yama finish the work = 60 days.
