If the highest guy is
No:10 he will make 9 handshakes
No:9 will make 8 handshakes
No:8 will make 7 handshakes
and so on
ie., 9+8+7+6+5+4+3+2+1 = 45 hand shakes in total.

Zero
Because a taller person wants to shake hands with a shorter person.
But the shorter person doesn't want to shake hands with him.

My work is based on give and take
I can make a difference by a hand shake
The older I get the smaller I grow
And my best friend is my worst foe

You are trapped in a room with two doors. You know there is a pack of hungry lions, certain death, past one door, and freedom behind the other. There are also two people, one guarding each door. They both know which door has freedom. One always tells the truth, the other always lies. You don't know who is who. You ask the person guarding door 1 one question. Then you need to choose a door. What question do you ask to give you a 100% chance of survival?
