    what is the solution ?

    Totally four band members are there.They want to cross the bridge.

    Due the age of the bridge, a maximum of two people can cross at one time. To make matters worse, it is night-time and there is only one torch. The torch is always required when crossing the bridge and the torch must be walked back and forth, it cannot be thrown, etc. Each band member walks at a different speed and a pair must walk together at the rate of the slower man:

    Bono takes 1 minute to cross
    Edge takes 2 minutes to cross
    Adam takes 5 minutes to cross
    Larry takes 10 minutes to cross

    For example, if Bono and Larry walk across first, it takes them 10 minutes to cross. If Adam then returns with the torch, a total of 15 minutes will have passed. There is no trick behind this, it is the simple movement of resources in the appropriate order.

    Finally all are cross the bridge in just 17 minutes...What is the solution ?

    this is my try!! 1.let bono and edge cross the bridge first(time=2min) and let bono come back with torch(time = 1min)-->hence 3 mins gone 2.now let adam and larry cross the bridge(10mins)-->give the torch to edge and let him come back(2 mins)-->15 mins gone 2.now let bono and edge go together again(2mins)-->hence total comes 17 mins gone

    is this the way??
