Answer 1

Answer:

12 days

Step-by-step explanation:

Time taken by A and B to plough the field together = 4 days

Time taken by B to plough the field = 6 days.

∴ A and B's 1 days' work = 14 A's 1 days' work = 16

Now, B's 1 days' work = (A and B's 1 days' work) - (B's 1 days' work) =

1/4 −1/6 = 3−2/12 = 112

Hence, A can plough the field in 12 days.
