Question :
Who won the maximum amount of prize money in the friendly boxing competition ?
Mr Muhammad Ali
Mr Iron Mike Tyson
Mr Big George Foreman
Mr Robert Duran
At the end of the competition, it was found that by sheer coincidence, all the boxers had won one million USD less than the world ranking number they were bestowed with before the friendly competition.
So world number eight would have won 7 million USD as prize money, world number seven 6 million USD, and so on, with world number one winning no prize money.
But, it is also informed that according to the rules of the competition, every boxer was to fight all the others exactly once. The fights would go on till one fighter loses on points, gets knocked out or concedes defeat. The winner of every fight would win 1 million USD as prize money, while the loser would get no prize money.
Hence, to win 7 million USD, seven fights have to be won, to win 6 million USD, six fights have to be won, and so on, with no prize money implying not a single fight won.
Hence the actual scenario that must have occurred in the friendly competition must be as depicted below :

We know that the world number three is Mr Rocky Marciano.
Also from the data provided in the incomplete table in the question, we can see :
a) Mr Iron Mike Tyson wins against Mr Manny Pacquiao and Mr Sugar Ray Robinson
b) Mr Muhammad Ali wins against Mr Iron Mike Tyson and Mr Sugar Ray Robinson
c) Mr Robert Duran wins against Mr Big George Foreman
d) Mr Rocky Marciano wins against Mr Joe Frazier
e) Mr Manny Pacquiao wins against Mr Robert Duran
f) Mr Sugar Ray Robinson wins against Mr Rocky Marciano
g) Mr Joe Frazier wins against Mr Big George Foreman
So everybody has won at least one fight except Mr Big George Foreman. So Mr Big George Foreman is the world number one.
Mr Rocky Marciano , who is world number three and hence won two fights, must have won against Mr Joe Frazier (as given) and Mr Big George Foreman.
Hence Mr Joe Frazier must be world number two, and has won against Mr Big George Foreman.
Mr Iron Mike Tyson won against Mr Manny Pacquiao and Mr Sugar Ray Robinson, who in turn have won against Mr Robert Duran and Mr Rocky Marciano, who again in turn have won against Mr Joe Frazier, and Mr Big George Foreman.
So Mr Iron Mike Tyson has won against all the six boxers mentioned above.
So Mr Iron Mike Tyson is world number seven.
Mr Muhammad Ali has won against Mr Iron Mike Tyson, and hence must have won against all the six boxers Mr Iron Mike Tyson won against.
So Mr Muhammad Ali has won seven fights and hence must be world number eight.
Mr Sugar Ray Robinson was not accounted among the top five rankers in the world.
But the seventh and eight rankers are Mr Iron Mike Tyson and Mr Muhammad Ali.
So Mr Sugar Ray Robinson must be world number six, and must have won against all except Mr Iron Mike Tyson and Mr Muhammad Ali.
The only two rankings left vacant are world number four and five, and the boxers in contention are Mr Manny Pacquiao and Mr Robert Duran.
But Mr Manny Pacquiao has won against Mr Robert Duran. So Mr Manny Pacquiao must be world number five and Mr Robert Duran world number four.
Hence, the final scenario is as below :
World No |
