Answer:
6 bundles
Explanation:
Each person made 9 cards
and there are 4 persons
Hence, the total number of cards is the multiplication of these. So
Total Number of Cards = 9 * 4 = 36 cards
Since, they will pile up them in GROUPS of 6, the number of groups that will be made is:
36 / 6 = 6
Hence, there will be 6 bundles in total
