Answer:
5 Days.
Step-by-step explanation:
According to the problem,
2 people can build a house in 10 days.
So by the law of inverse proportion, even after the change in number of people working the output will be a constant value.
Therefore,
Let the time required to complete the same work by 4 people be X.
⇒ 2×10 = 4×X
⇒ 20=4×X
⇒ X=20÷4
⇒ X=5.
The time required to 4 people to complete the same work is 5 days.
