Question

If 5 men can cut 50-meter long wire in 5 days, in many days 4 men can cut a 40-meter long wire?

Answer 1

Answer:

4 men can cut 40 metre long wire in 4 days

Answer 2

Answer:

4 men can cut a 40-meter long wire in 3.2 days.

Step-by-step explanation:

If 5 men can cut 50-meter long wire in 5 days.

Then the same 5 men can cut 40-meter long wire in x days. (let's assume.)

Then x =  40 m (5 days)/50 m = 4 days.

Hence, 5 men can cut 40-meter long wire in 4 days.

Now, we are interested in finding how many days 4 men can cut a 40-meter-long wire.

But from the above calculation 5 men can cut 40-meter long wire in 4 days.

So let's assume 4 men can cut a 40-meter long wire in y days.

Then, y = 4 men(4 days)/5 men = 3.2 days.

Therefore, 4 men can cut a 40-meter long wire in 3.2 days.
