Anuj & Bhanu finish the work in 30days.
In 20 days they have finished 20/30= 2/3 of work
The work left was 1-2/3=1/3
Anuj finished the work 1/3 work in 20 days
Anuj would finish the whole work in 1*20/(1/3)=60 days.
Alone Anuj would finished the work in 60days.

60 days
A+B=1/30 of the work in one day
In one day 20(1/30) of the work completed. Therefore 1/3 of work left
It takes 20 days ( anuj ) to complete 1/3 of work
Therefore work done in one day (1/3)/20=1/60
Therefore he will complete the work in 60 days alone
