Question

If 20 people can construct a house in 30 days, how many people needed to construct the same house in 5 days?

Answer 1

Answer:120 people

Step-by-step explanation:

Let total work =(lcm of 20,30)

=60

20 men 1 day work =60/30=2w

1 men 1 day work= 2/20=1/10

A/c to question

We have to finish work in 5 days.

So we have to do 60/5=12 W in one day.

1 people do 1/10 work in one day

120 people do 12w in one day.

Ans= 120 people.
