Explanation:

Work done by first son in one day = 1/6
Work done by second son in one day = 1/12
Work done by father in one day = Work done by first son in one day + Work done by second son in one day
Work done by father in one day = 1/6 + 1/12 = 1/4
Therefore father will take 4 days to finish the work.
