  • RE: Crossing the Bridge Puzzle
    Starter Asked on 28th September 2016 in Easy puzzles.

    Assumption: – If two person walks together they will move according to the person walking slower than the other one because of torch constraint.

    A – 1 min
    B – 2 min
    C – 7 min
    D – 10 min

    First send C & D : time taken – 10 min

    Send A to get the torch and bring it back : time taken – 2 min (to & fro)

    Now A & B can go together : time taken- 2

    Total time – 10 + 2 + 2  = 14min
