Multiplication of 2 integers is between 15 and 200. Start evaluating the options. The min option is 3 and max is 15.
15*16 > 200 so 15 cannot be in the deck
Next max to 15 is 14
14*15 > 200 so 14 cannot be in the deck
Check 13
13*14 < 200 so this is possible.
Now evaluate lower side of the numbers
3*4 < 15 so 3 cannot be in the deck
4*5 > 15 so 4 is possible
Ans 4-13.
