Step-by-step explanation:

16 men can do the work in 40 days therefore 24 (16*1.5) can do the work in 80/3 (40/1.5) days.

28 boys do the work in 40 days therefore 14 boys (28/2) can do the work in 80 (40*2) days.

Therefore 24 men and 14 boys can do the work in

1 / (3/80 + 1/80) = 1 / (4/80) = 80/4 = 20 days.

So, 20 days is the required answer
