same as my comment above. Answer: well if the four men are going to work at the same rate, it is gonna be a double work-load to complete. the actual work-load is 8x10 (eight times ten) men-hours. to get the number of hours the four men are gonna take to complete the work you have to divide the work load (men-hours) by four. the answer is 20 hours.

Well, I think I can see where this joke is going... It would take the exact same amount of time, because one would build it and the rest would supervise... Am I right?

considering all the persons to be equally likely i.e,they put almost the same effort in equal time,it will take 20 hours for four men to build a wall
