Question 966484


According to the condition, &nbsp;the product &nbsp;&nbsp;(<U>number of workers</U>) x (<U>duration of construction in days</U>) = constant, &nbsp;&nbsp;is the constant value.


Therefore, you can solve the problem as follows.


It takes &nbsp;10 people x 40 days = 400 people-days to build the house.


Hence, &nbsp;8&nbsp; people can build the house in &nbsp;{{{400/8}}} = 50 days.
