two school play against each other in a grace court tennis tournament. Each school is represented by 8 students. Every game is doubles game, and every possible pair from the first school must play one game against every possible pair from the second school. How many games will each student play?

• No of games each student plays=(no.of possible ways of forming a team WITH HIM in his school)*(max no.of.possible teams in another school)
  no of possible doubles pairs with the student=7
  max no.of.possible teams in another school=7+6+5+4+3+2+1=28
  Therefore,no.of games each student plays=7*28=196
