If it took 8 man 10 hours to build a wall , hou long would it take 4 men build it ?✌️​

Answer 1

Explanation:

Here it is an indirect proportion.

8×10=4×x

where x is number of hours required by 4 men to build that wall.

=2×10

=20 hours

Therefore,4 men will take 20 hours to make it.

Answer 2

Answer:

no. of hours to build a wall with 8 men= 10hr

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
