Five people meet and exchange handshakes. If exactly 3 of the
people each shake hands with 3 people, and if 1 people shakes hands
with 1 other person. Then what is the least number of handshakes that
could have been exchanged?

I get 6

If we have 5 people: A,B,D,E and F

A,B,D must shake 3 times each
F must shake once at least


If ABD shake hands with one another we have 3 different shakes so far.

And A,B and D still have to make another shake.

A shakes E (we have 4 shakes now)
B shakes E (we have 5 shakes)
C shakes F (we have 6 shakes)

3 people shake hands ... 3*2/2 = 3

1 person shakes hand with another = 1

Remaining one shakes hands with another one = 1

i would say 5

I got 7.

A B C D E

A, B, and C handshake one another = 3 (each shakes the other two)
A, B, and C handshake D=3 (in total A, B and C make 3 shakes each)
E handshakes D one time

Thus, I have 7.
