I think Answer is 2 days..
Suppose 1 man can do work in X days..
so 4 men will do in ..
4/X=1/5*1/2 as half job is done
X=40
now 6 more are added then
10/40=1/2*1/d for remaining half job
d=2 Number of days

Total work in men-days unit = 4*5*2
Now work done by 4 men = 4*5
6 people added and let say they take d days to complete the rest half = 10d
4*5*2 = 4*5 + 10d
=> d = 2
So a is the answer
