Question

30 log hanth milaye to kitne handshake honge

Answer 1

Answer:

Agar dono hath ho se handshake kiya jaye toh:-

30 x 2= 60

Answer 2

Total no. of people = 30

As you cannot do handshake with your hands, so total handshakes = 30*29

But no two people are handshaking their hands twice.

.•. total number of handshakes = (30*29)/2 = 870/2 = 435
