Answer 1

`3 3/5`days.

Explanation:

A does in 1 day = 1/6th part of the work and B does in 1 day = 1/4th part of the work.

A does in 2 days = `1/6 *2 = 1/3`part of the work.

The left over work = `1 - 1/3 = 2/3`rd part

A and B together do in 1 day = `1/6+1/4 = 5/12`th part.

Hence A and B will do 2/3part of the work = `12/5. 2/3 = 8/5`days.

Therefore total time taken to complete the work = `2 + 8/5 = 3 3/5`days.
