Each person says "Good Evening" to 11 other people. Assuming it is said back, it is done by 12 people.
11 * 12 = 132 times

1 says hi to 2 3 4 5 6 7 8 9 10 11 12
2 says hi to 3 4 5 6 7 8 9 10 11 12

First, you need to give every person a number. then, with those numbers, make an ordered list ex: 1 said good evening to 2;3;4;5;6;7;8;9;10;11;12. Is it assumed that in return each person said good evening to person 1? ask your teacher. if so, then person 2 only said good evening to 3;4;5;6;7;8;9;10;11;12. and so on...
