If it takes 2 people 2 days to paint a wall, how long will it take 4 people?
Correct answer: A. 1 day
- A. 1 day
- B. 2 days
- C. 4 days
- D. 3 days
Explanation
If 2 people take 2 days to paint the wall, the total work done is 4 person-days (2 people * 2 days). If the workforce is doubled to 4 people, the same amount of work (4 person-days) can be completed in half the time, which is 1 day. Thus, with 4 people working, it will take only 1 day to paint the wall. Option A is correct. Options B, C, and D are incorrect as they do not account for the increased workforce reducing the time proportionally.
