Here is my question: in a certain card game, for every 3 yellow cards there are 4 blue cards. There are a total of 84 blue and yellow cards. How many blue cards are there?

4 blue + 3 yellow = 7 cards (1 set)

Total of 84 cards has 12 set of cards (84/7 =12)

So, no. of blue cards are 12*4= 48 cards
