The concept used for this item is equating the man-hours for both scenario. Man-hour is calculated by multiplying the number of men working by the number of hours they need to finish the work. That is,

(15 men) (7 hours) = (35 men) (x hours)

The value of x from the equation is equal to 3. Therefore, it will only take 3 hours for 35 people to do the same job.
