Answer:
6.2 days
Step-by-step explanation:
A completed his work in 10 days.
B completed his work in 12 days.
the average days if B leaves 2 days before= (10+10)/2
=10 days.
the total time taken by both if B is there for all 10 days = 5 days
if B leaves 2 days before,
then
the remaining days of B for A is 12/10
=1.2 days
the total time taken to complete the work is 5+1.2
= 5.2 days
