Answer 2

Answer:If 5 men can finish the work in 12 days, how many men are required to finish the same work in 6 days?

It's a trick question……which seems like percentage question but here is a small difference.

Let me explain …….

When we are said to calculate 25 percentage discount what do we do

Out of 100…….25 discount

So on MRP ……? Discount

So then ? = MRP×25/100…we normally do this.

Now reading the question we normally do the same as above like….

12 days taken by 5 men

So 6 days taken by ? Men

?= 6×5/12 =2.5 men which is wrong answer.

But here in our question we need not to focus on number of person ….. instead we should focus on amount of work.

Here we should take instead of 5 person 1/5 th work…..! Like…..

In 12 days 1/5 th work done

So in 6 days ? Th part work done.

? = 6×(1/5)/12 = 1/10 th part of work.

Now 1/10 part of work is done by each men so the work will get done in 6 days. So for whole work we will need 10 men.

Here the ans is 10 men required
