Answer 1

Answer:

It will take 3 days to rewire her house in with 4 people.

Step-by-step explanation:

3 persons could rewire her house in 4 days

∴ Total work = 3 × 4 = 12 Units

Now, 4 people are doing the same work.

Number of Days Required = $\frac{Total \ Work}{Number \ of \ People} = \frac{12}{4} = 3$

∴ It will take 3 days to rewire her house in with 4 people.
