Twelve participants in a conference shook hands before and after the meeting. How many handshakes took place in total?
Explanation
The first person shook hands with the 11 remaining people, and the second person also shook hands with 11 people, but we count 10, as the handshake with the first person has already been counted. Then add 9 for the third person, and 8 for the fourth one & proceeding in this fashion we get: 11 + 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 66. Hence 66 handshakes took place before & 66 after the meeting, for a total of 132
