Question

If it takes eight men, ten hours to build a wall, how long would it take four men? just for something that's for bonus. Care to try? LOL

Answer 1

Answer:

20 hours

Explanation:

Since 4 men as half as many as 8 men, it will take double the amount of time to perform the same amount of work. Therefore, it would take 20 hours to build the wall.

Answer 2

8 men takes 10hrs

1 man will take 8×10=80hrs

4 men will take lesser time than 1 person doing the same work alone hence time taken by them is 80/4=20hrs
