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.
