Answer:

4 days

Step-by-step explanation:

Work done be a -

12 days = 1 work (Work completed is taken as 1)

1 day = (1/12)th work

Work done by b -

6 days = 1 work

1 day = (1/6)th work

When both will work together then work done in 1 day = 1/12 + 1/6 = (1+2)/12 = 3/12 = (1/4)th work

As in 1 day (1/4)th work is done, full work will be done in 4 days
