hello tarun click answer on the right side bottom of the question then you can see the question my friend :)
@ Srini: Ur right machan !
If the number of people are 'n' then
number of handshakes = (n-1) + (n-2) + (n-3)+ ...+1
or number of handshakes = n(n-1)/2
here number of handshakes = 28
So, n(n-1) / 2 = 28 on solving gives
n = 7
