Not possible :)
Lets say the 5 members of family are A ( 1 ), B ( 3 ), C ( 6 ), D ( 8 ) and E ( 12 )
Now, since lamp is necessary for the trip...
Minimum time taken will be
AE go, A comes back = 12 + 1 = 13
AD go, A comes back = 8+ 1 = 9
AC go, A comes back = 6+1 = 7
AB go finally = 3 seconds
Minimum time required = 13+ 9 + 7 + 3 = 32 Seconds :idea:
Any other combination should take more than this time...
so well... what am i missing? ( nothing :?: )
So, was this a HR question?????? :lol:[/list]

I solved this in 3 attempts...
Here giving the answer for whom who tried really hard, or who assumes it is mathmatically impossible.
Here we find 5 charactors with the speed of 1,3,6,8,12 right!! and at a time two can go....
Try this one (WE name charactors according to thier moving speed)
1... 1 and 3 will go (3 Second)
2... 1 will come back (1 Second)
3...8 and 12 will go...(12 second)
4...3 will come back (3 second)
5. 1 and 6 will go (6 second)
6. 1 will come back (1 second)
7. 1 and 3 will go ( 3 second)
Total 29 second and 1 second remains.

Friend; :)
Its a nice exercise ;if you dont want to try i can help with the answer;but let me share with you a hint for one more try..
Hint: The two of the slowest can go together i.e 12,8 (coz anyways you will rquire 12sec to cross the chap irrespective of who accompanies him ,and then you require some one of 1/3 to be there to bring back the lamp)
this should solve this puzzle... :D
