First person shakes hands 19 times, second person 18 etc, a total of 190.

20 hand shakes would take place. Here's how: 1234567 23456 34567 4567 567 67 7 And a person can't shake his own hand or someones hands twice

If each person is shaking with only one hand, then the answer is seven. If they are shaking with both hands, then the answer is 14.

At one time, this was a kiss. Now, the congregation shakes hands and says "Peace be with you."

Actually, that is incorrect. Not everyone would shake hands 27 times with another person, otherwise there would be people shaking hands more than once. I'm not entirely sure of the rule for this but this will help. 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 28 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 0 Now the problem does not fully solve that but it explains some things the last person shakes hands with no one because everyone shakes his hand. the first person shakes hands with everyone except himself. So what you do is you add up how many handshakes each person makes. you come to 378. Noone here knows math That works, but it's a lot easier to just use this function: number of handshakes = 0.5*(X2-X) Where X is the number of people. It's a lot easier, and less time consuming.
