It was found that there were a total of 46 people at a company dinner. Each of the persons shook hands with all other paersons. What would be the total number of hand shakes?

• n(n-1)/2, n is the no. of people

• 46C2=1035 handshakes
• 7 years agoHelpfull: Yes(7) No(0)
• total=46 people
  46 people give s.h to 45 people
  so 46*45=2070

• The formula is- n(n-1)/2;
  here n=46 (given)
  so, n(n-1)/2= 46(46-1)/2;
  46*45/2= 1035.
  Total number of handshakes 1035.

  3 1 + 2 = 3
  4 1 + 2 + 3 = 6
  5 1 + 2 + 3 + 4 = 10
  6 1 + 2 + 3 + 4 + 5 = 15
