  1. First A and B went , they took = 2 mins

    A came back = 1 min

    A and C crossed , took = 5 mins

    A came back = 1 min

    A and D crossed finally = 10 mins
    _______________________________

    Total = 10 + 1 + 5 + 1 +2 = 19 mins ?

  2. Umm, Reduced it a bit to 17 mins,

    A and B went = 2 mins
    A comes back = 1 min

    C and D passes with taking the torch from A = 10 mins

    B comes back to take A = 2 mins

    A and B passes finally = 2 mins
    —————————————————————–
    17 mins total, can it be reduced further?
