• There will be total 28 handshake
  the shortcut formula is
  sigma(number of people - 1)
  if there will be 8 people then total combination
  7+6+5+4+3+2+1 = 28

• answer : 14 shakes
  
  formulae:
  
  2*(n-1)=y
  where n= number of persons
  y= number of shakes
  
  so there are 8 people in room means n=8
  then 2*(8-1)=2*7= 14
