John has 51 cards.
Paul has 32 cards.
George has a number of cards greater than either Paul or John.
This means, George does have number of cards greater than both Paul and John.
Number of Cards with John is 51 and number of cards with Paul is 32 cards.
Therefore the number of cards that George may have is in between 33 and 51
If George has any number of cards greater than 32 and less than 52, then this number of cards is greater than cards with Paul but less than the cards with John.
Number of cards George has is > 32 but < 52
Hope this helps..!!
Thank you:)
