The answer is 21.
since each person should handshake for  one time. The first person handshakes with 6 persons and 2nd person with 5 persons and 3rd with 4 persons and 4th guy with 3 persons and 5th one with 2 persons . sixth persons need not to handshake as others given and the total is 6+5+4+3+2+1=21.
