Answer / sandeep
With two people, there is one handshake. With three people,
there are three handshakes. With four people, there are six
handshakes. In general, with n+1 people, the number of
handshakes is the sum of the first n consecutive numbers:
1+2+3+...+10. Since this sum is n(n+1)/2, we need to solve
the equation 10(10+1)/2 = X. Solving for X, we obtain 55 as
the answer.
