 Thu Feb 20, 2014 1:35 pm  by ashta27 People the answer is 6. Here's a clear explanation. There are 4 people namely A B C D. A shakes hand with B C D. B shakes hand with C D. (B has already shook hands with A in the line above so he won't do it again) C shakes hand with D. It's essential to remember that everyone shakes hands with others only once. So AB is the same as BA. I hope it's clear. If not I'll be happy to answer any query.
