the answer is 12...

ex: there is guy 1,2,3, and 4

1-2, 1-3, 1-4
thats 3 hand shakes
continue with guy 2,3, and 4. or do 3 times 4. either way you find 12

The answer is 6.
For those who have heard of Combinations and Permutaions, the answer [size=9]4[/size]C[size=7]2[/size].

6 only,

1st person hand shakes with 2,3,4 is equal to 3 handshakes
2nd person hand shakes with 3,4 is equal to 2 handshakes
3rd person hand shakes with 4 is equal to 1 handshake
4th person has already shook hands with all of them, so a total of 6

I agree with wesmode & einsteinager. The answer is 6.

if 4 persons are A,B,C,D

They will shakes their hands with each person like

AB, AC, AD, BC, BD, & CD

So if is mote than 6 time then it would be doubled.

People the answer is 6.
Here's a clear explanation.
There are 4 people namely A B C D.
A shakes hand with B C D.
B shakes hand with C D. (B has already shook hands with A in the line above so he won't do it again)
C shakes hand with D.
It's essential to remember that everyone shakes hands with others only once. So AB is the same as BA.
I hope it's clear.
If not I'll be happy to answer any query.

like the 2014 world cup, each group has 4 teams and each team played 6 times to complete the first round game!
