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.
