How many tough guys?
The key thing to keep in mind is that no matter how many there are, they could smoke simultaneously, not one after the other.
A rather unhealthy riddle. If you smoke, I’d recommend quitting. Especially if you do it at the pace of these guys, each one puffing one cigarette every three minutes. I don’t even know if you’d survive long enough to solve the riddle before your lungs give out. I’ve just told you how many cigarettes one guy smokes in three minutes. This information will help you figure out if they need to invite more tough guys to join the group.
"The correct answer is '3'. Each one smokes 1 cigarette in 3 minutes. Therefore, each of them smokes 10 cigarettes in 30 minutes. With three of them puffing away at the same time, that makes thirty cigarettes in thirty minutes.
