In the space of the 12 consecutive integers on the cards, you must be able to multiply two of them and get 40, two others and get 72, and two others and get 60. (There can be overlap.) So, determine which numbers you could use to get each of those numbers:
40: 4 and 10, 5 and 8 (1 and 40, and 2 and 20 are too far apart)
72: 6 and 12, 8 and 9
60: 4 and 15, 5 and 12, 6 and 10
Due to 40, there must be at least one number in the deck that is 5 or lower. While, due to 72, one number must be 6 or higher. So, the correct answer is (E), 6: if the smallest numbered card is 6, there’s no way for two of the cards to multiply to 40.
