Principle 1: Number of days to cut the wood is inversely proportional to the number of men. (i.e. the more men, the less number of days it will take to cut the same log of wood. Also, less men means more days to cut the log)
"Inversely proportional" in mathematical terms means
"number of men * number of days" is a constant - which is the time taken for ONE person to complete the work.
10 men can cut the log in 4 days.
So, ONE man can cut the log in 10+%2A+4 = 40 days.
Now if there were 8 men, they would complete the work in: 40+%2F+8 = 5 days
Answer: 8 men can cut the log of wood in 5 days.
