The actual solution to this problem is like this- 1 can shook hands with a max. of 35 people. Then 2 can shook hands with a max. of 34 people (this is the total handshake made including the handshake with the 1st person). Then 3 with max. 33, 4 with 32, 5 with 31, 6 with 30, 7 with 29 and 8 with 30 ...
