Anil can complete the work in one day =1/10
Sunil can complete the work in ine day
=1 /12
They can do together work in two days alternately
=1/10+1/12=11/60
The part of work done by each in 10days alternately(each 5 days) =55/60=11/12
That is alternatively in 10 days =11/12
Remaining work =1-11/12=1/12
This work can be completed by anil on 11th day. This can be done in
=10/12 days=5/6 days.
Therefore the total work will be completed in 5+5+5/6=65/6 days.
