Answer:
Total number of handshakes =
9+8+7+6+5+4+3+2+1 = 45
Step-by-step explanation:
See it this way.. 10 persons A to J.
A can shake hands with B,C,D,E,F,G,H,I,J that is 9 persons.
Similarly B can shake hands with 8 people (As A has already shook hands with B, there is no need for B to shake hands with A again ).
C with 7…. D with 6…. E with 5…. F with 4…. G with 3…. H with 2 and I with 1(i.e. J).
Total handshakes = 9+8+7+6+5+4+3+2+1 = 45.
