Well I should say guys only as they are the ones who typically start some of the most pitiful threads
here's something to occupy your (mostly happy and cheerful but some notorious and unclean) minds (it's a simple one)
There are four people who cross a certain bridge. Individually they can cross in 1min, 2min, 5min and 10min. They have one flashlight among them. The bridge is big enough for just two to pass at any time - so you guessed it - two pass over it and then one has to come back with the flashlight. And the two who pass over will have to travel at the speed of the slower person i.e. if 1Min and 10Min pass over, it will take 10Mins.
What is the least time it will take for all four of them to cross the bridge?
