At a round table, 8 people are seated. Every person shakes hands with everyone except the person directly opposite them and the two people sitting immediately beside them. How many handshakes take place in total?
16 handshakes
Out of 7 other people, each person excludes 3 (1 opposite + 2 adjacent), so each person shakes hands with 4 people. With 8 people, total handshakes = (8 * 4) / 2 = 16.
