Q30) In a soccer tournament n teams play against one another exactly once. The win fetches 3 points, draw 1 each and loss 0.

a) 5
b) 6
c) 7
d) 8
e) none of these

@rowdyrathore Shouldnt it be smallest value of n greater than 5 , or any other limiting factor?

@rowdyrathore We select two points out of 98 to make a chord, given by 98C2. This gives 4753 , which leaves a remainder on dividing by 3 .thus anthony wins.

@rowdyrathore The rth match in Round 1 will be played between Seed ‘r’ and Seed ‘n+1r’
so 7th match will be played between seed 7 and seed 32+17=26
and 10 th match will be played between seed 10 and seed 32+110=23
