There are 80 men in a race. 1/4 of the men tripped and were unable to finish. 2/3 of the remaining men were dehydrated and 1/5 of those dehydrated men couldn't finish the race. How many men finished the race? Let's be accurate as possible.

1 / 4 of 80 men is 80 / 4 = 20 men. 20 men couldn't finish, so 80 - 20 = 60 men remain. 60 * 2 / 3 = 40 men were dehydrated. 1 / 5 of the dehydrated couldn't finish 40 * 1 / 5 = 8 men. 60 - 8 = 52 men finished the race.
The answer: 52.
