Answer 2

67 is the sum of handshakes given by the first and second participants.

Let n be the total number of participants in the workshop venue.

i.e, here n= 35

For the first participant, the number of handshakes is  = (n-1)

                                                                                           = (35-1)

                                                                                            = 34

The number of handshakes by the second participant is also same as that of the first participant  = 34

The number of handshakes  given by the first and second participants together  

          = ( first participant handshake + second participant handshake - 1 )

          = (34 + 34 -1 )

          = 68-1

          = 67
