3. answer can be 1,2,3,4 can’t be determined exact number
   just explaining a case:
   there are 10 people in the party.
   name of people no. of people with they made handshake list of those people(this can vary but showing the possibility)
   1 1 9
   2 2 8, 9
   3 3 7, 8, 9
   4 4 6, 7, 8, 9
   5 5 6, 7, 8, 9. 10
   6 6 4, 5, 7, 8, 9, 10
   7 7 3, 4, 5, 6, 8, 9, 10
   8 8 2, 3, 4, 5, 6, 7, 9, 10
   9 9 1, 2, 3, 4, 5, 6, 7, 8, 10
   10 4 5, 6, 7, 8, 9
   jack got 9 different answer so jack can be either 4th number or 10th number and jack’s wife know jack very well so she can’t have handshake with jack so if 4th is jack then she can’t be handshake with 6,7,8,9, in this case she can be 1,2,3, 5, 10 and now depending upon which no is jack’s wife she can have hand shake with- 1- 4 people, and if jack is number 10 then she can’t be 5,6,7,8,9 so again depending upon her number she can handshake with people in range of 1-4
