Question

Answer 1

Answer:

The 6 people will paint the wall in 6 hour's.

Step-by-step Explanation :

Given : 4 people can paint a wall in 3 hours.

To find : How long will it take 6 people to paint it?

According to given conditions,

4 people -------------- takes 3 hours

So, first we will find the time taken by 1 person to paint a wall ,

We know that the time taken by 1 person will be more so we multiply,

∴ 1 person will take 4 × 3 = 12 hours to paint the wall.

So, now we know that 1 person will complete the painting in 12 hours .

Since the amount of work to be done is same,

Now we will find the time taken by 6 people to paint the wall,

As we can say from our basic understanding that as number of people's are more so time taken will be less. So we divide.

∴ 6 people will take 12/6 = 2 hours to paint the wall

Hence the 6 people will paint the wall in 6 hour's.
