7 people meet and shake hands with one another, how many
handshakes occur?
Answer Posted / suma
21 is correct
suppose 1,2,3,4,5,6,7 people.
1st one(tillu) shakes hand with all other 6 members.
then 2nd one(bunty) with 5 people only,since already he
shook hand with tillu.
then 3rd one with 4 people only.(with tillu &bunty its
over)
so 6+5+4+3+2+1=21
(7th one need not do it. already every one shook hand with
him,so not counted him)
