SOme of my friends were messaging me privately to know the answer of yesterday's brain teaser. Next time, plz post yr message in comment. SO, others can see what you all thought.
The answer for brain teaser 2 is:
"Happy Birthday."
This song can be sung with anyone's name in it.
Teaser for today:
Four members of a band are walking to a night concert. They decide to take a shortcut, but must cross a bridge. Luckily they have one flashlight.
Because of the varying size of their instruments, it takes each member a different amount of time to cross the bridge - it takes:
1st person - 1 minute
2nd person - 2 minutes
3rd person - 5 minutes
4th person - 10 minutes
They must cross the bridge in pairs, travelling at the slower speed so if the one minute person went with the ten minute person, it would take a total of ten minutes.
Since there is only one flashlight, one person must come back across the bridge, then another pair can cross. They only have 17 minutes to cross the bridge and still get to the concert on time.
What order should they cross to get everyone across and get to the concert?
