Step-by-step explanation:
Let x is the time it takes 1 man, 1 woman and 1 boy to do the piece of work
One man works at the rate of
44
1
of the piece of work per day
One women works at the rate of
2×44

=
88
1
of the piece of work per day
One boy works at the rate of
3×44
1
=
132
1
of the piece of work per day
So, to complete the piece of work we can write the equation as

x+
132

x=1
⟹x=24
Therefore 1 man, 1 woman and 1 boy can do the same piece of work in 24days
