This is how this works:
First - Person 1 and 2 go over the bridge and Person 1 drops person 2 at the end and gets back with the light!. Total time taken is 3 minutes
Second - Person 3 and Person 4 cross the bridge with the light and give it to Person 2 who comes back to the beginning!. Total time taken is 12 minutes!.
Third - Person 1 and Person 2 (the only ones who are left) cross the bridge!. Total time taken is 2 minutes!.
Therefore the whole exercise takes 3+12+2=17 minutesWww@Enter-QA@Com

P1 goes = one minute
P2 goes =2 mins
P3 goes=5 mins
p4 goes=10 mins
1+2+5+10= 18 every person completes the bridge and throws the flashlight to the other one so they can go in 18 mins
but you can make two persons walk with each other
P2 will go withP3(they will take five mins togather) (same time) so we can so we can remove him from the equaition(we will put him with P3)
P1+P2and P3+P4=
1+5 +10=16mins
ofcourse every one will throw the flash light to the other when he crosses the bridge
or they can cross at the same time and it will take 10 minsWww@Enter-QA@Com
