Answer / guest
132
Think of it this way: the first person shakes hands with 11
people, the second person also shakes hands with 11 people,
but you only count 10, because the hand shake with the first
person was already counted. Then add 9 for the third person,
8 for the fourth, & so on.
66 hand shakes took place before & 66 after the meeting, for
a total of 132.

Hence for 12 people itis 12(12-1)/2= 66
Thus total handshakes = 2*66=132

At first time handshake will be 11 and decrease this to 1 that the formula of sum of this sereis is=n(n+1)/2.
that n=11 put in formula
(11*(11+1)/2)=66
66+66=132 bcoz handshake will be two times
