Felix found the sum of two prime and one compostie number to be 45. The difference between the greatest and the least number is 4. Which one could be the three numbers?
The correct answer is A. The first thing to look for are obvious answers to rule out. You can automatically rule out B and C because they have 2 composite numbers. That leaves A and D, it can't be D because 19-11 is 8 and not 4. So, the only answer can be A.
