There are people at the party including Abhishek and Aishwarya. If Abhishek shook hands with m woman as many times as men and aishwarya shook hands with n men as many times as woman.
Find how many people were there at the party. If n = 4 and m = 3.

• The basic formula to note in handshake problems is nc2 though the handshake is 1 but the people are 2.Here,they have already given the values of n and m so apply the formula nc2=4c2=6 and mc2=3c2=3.Therefore,6+3=9

• Abishek shook hands with 3 women = no of men =3 +1 including Abhi
  Aish shook with 4 men = no of woman = 4 + 1 including Aish
  total = 4+3+2 = 9

• As given in the question,
  Abhishek shook hands with m woman and Aishwarya shook hands with n men,
  then total no. of people= m+n= 3+4=7.
  (because it is not given that Abhishek did not shake hands with Aishwarya, so as per question we have to understand that Aishwarya was included in the woman).

• men=mc2(3c2)=3 women =nc2(4c2) ans=9

• Abhishek shook hands: 3C2
  Aishwarya shook hand =4C2
  3C2 + 4C2 =3+6=9
