Why do there exist a 50-move rule and a 75-move rule?

By number theory, if the 75-move rule has been reached, the 50-move rule will also be reached. This has no meaning. It is like saying "I would buy this book if it cost under $60 and it costs under $40". So, what is the logic behind that?

In cases where the 75-moves rule applies (e.g. 2B vs N, IIRC), it replaces the 50-moves rule : you cannot claim a draw after 50 moves, but you can do so after 75 moves.

So do you mean that the 50-move rule does not apply to 2B vs N games?

@Evargalo that used to be the case (in various forms) from 1928 to 1992: en.wikipedia.org/wiki/Fifty-move_rule#History

Yes, I was confused between two different 75-moves rules. Annatar's answer is spot on.

From the FIDE Laws of Chess:
50-move rule:
9.3 The game is drawn, upon a correct claim by a player having the move, if:
(...)
the last 50 moves by each player have been completed without the movement of any pawn and without any capture.
75-move rule:
9.6 If one or both of the following occur(s) then the game is drawn: (...) any series of at least 75 moves have been made by each player without the movement of any pawn and without any capture.
(emphasis mine)
As you can see, the decisive difference is that the 50-move rule only applies if a player correctly claims it, while the 75-move rule applies independently of any claims. So, in the 50 to 75 move window, the players can claim for a draw, but don't have to (and play on). Only when the 75th move without pawn moves or captures has been reached, the arbiter may interfere and declare the game drawn.
