Would you not be expected to also provide an argument that your solution is optimal?

In 9 minutes 1st 3rd and 4th reaches other side.
In 1 minute 1st comes back with the torch .
In 2 minutes 1st and 2nd reach the other side
total 12 minutes

1)9 min and 1 min walk together , 1min person reaches
2) distance remaining for 9 min person is 8 , time elapsed is 1 min
3) now 9 min person (8 min remaining ) and 2 min person walk together
4)2 min person reaches , mins remaining for 9 min person is 6 min , time elapsed 1+2=3
3) now 7 min person and 9 min person ( 6 min remaining ) walk together
4) time would be 7 min now
5) so total time 7+2+1=10

As per the question i think the above answer is perfect.But thinking a little out of the box since it is a bridge and hence must be over a river.So if we strictly count only the time taken to cross by them and not the time taken by the torch to pass from one side of the bridge to the next then the answer comes out to be 9 minute( person of 9 minute and 7 minute together) +2 minute( person of 1 minute and 2 minute together)= 11 minute total time to pass the bridge.

BUt here however we are neglecting the water current and the time it takes to move the torch in water
