in 0.8 Days more time work will be completed
Step-by-step explanation:
A takes 6 days and B takes 4 days to complete a work
A's 1 Day work = 1/6
B's 1 Day work = 1/4
A + B together 1 Day work = 1/6 + 1/4
= (2 + 3)/12
= 5/12
A's 4 Day work = 4/6 = 2/3
Remaining work = 1 - 2/3 = 1/3
Number of Days more time A & B will Take = (1/3)/(5/12)
= 12/15
= 4/5
= 0.8 Days
