Question

at a conference 12 members shook hands with each other before and after the meeting how many total numbers of handshakes occurred ​

Answer 1

That's 12 * 11 = 132. But we double counted (Alice shakes Bob's hand, Bob shakes Alice's hand, but only one handshake takes place), so divide by two to get 66 handshakes. That's before the meeting. Then another 66 handshakes after the meeting makes for 132 total handshakes.
