Hi again, here is the answer finally :)
person 1 (1min) & person 2 (2min) cross the bridge together---> 2 mins total
person 1 return ----> another 1 minute
person 3 (5 min) & person 4 (10 min) take the torch from person1 who just returned and cross together in total time -------> 10 mins
person 2 who is already on the other side, take the torch from them, and return with it in another --------> 2 mins
now person 1 & 2 cross together in ------> 2 mins
sum all the previous times you will find them 17 mins exactly :)
have a nice day
Your are welcome :D
