Answer:

To solve this problem, you can use the concept of "man-hours," which represents the total work done in terms of the number of people working and the time taken.

Step-by-step explanation:

If 4 people can build a house in 10 hours, then the total man-hours required for the house construction is:

4 people * 10 hours = 40 man-hours

Now, you want to find out how many hours it will take for 7 people to build the same house. Let "x" be the number of hours required.

Using the concept of man-hours, you can set up the equation:

7 people * x hours = 40 man-hours

Now, solve for "x":

7x = 40

x = 40 / 7

x ≈ 5.71 hours (rounded to two decimal places)

So, it will take approximately 5.71 hours for 7 people to build the same house.

10*60= 600 minutes / 4

= 150 for 1 person

for 7 person

= 150 *7

=1050 minutes

hour = 1050 ÷ 60

= 17 hours 30 minutes

= 17.5 hour
