Answer:
Step-by-step explanation:
A's one day work=1/14
B's one day work = 1/21
{A+B} one day work = 1/14 + 1/21 = 5/42
they both work 6 day = 5/42*6=5/7
work=1-5/7=2/7
B had to complete the work=2/7 divided by 1/21
=2/7*21/1=6
total time taken =6+6=12
therefore it took 12 days to complete the work.
