Question

Four people come to a river in the night. There is a narrow bridge, but it can only hold two people at a time. They have one torch and, because it's night, the torch has to be used when crossing the bridge. Varun can cross the bridge in one minute, Amol in two minutes, Sandesh in five minutes, and Premi Sir in eight minutes. When two people cross the bridge together, they must move at the slower person's pace. What would be the least total time taken for all to cross the bridge ?

Answer 1

It will take 16 minutes
