(13/59)(c/58)=117/1711

13c/3422=117/1711

13c=234

c=18

So there are 18 clubs instead of 13 meaning that there is an extra 5 clubs in the deck.

Since there were 59 cards, there was 7 extra cards in all.  The 7 extra minus the 5 extra clubs leaves 2 extra spaces.

So there were two extra spades in the deck.
