The video tutorial explains how to solve a problem involving calculating the time it takes for a different number of men to build a wall at the same speed. Initially, it takes four men six days to build the wall. The tutorial guides through the process of determining how long it would take one man, and subsequently three men, to complete the same task. The solution involves understanding the relationship between the number of workers and the time taken, leading to the conclusion that three men would take eight days. The tutorial also highlights the importance of each step in the calculation for scoring marks.
