A number with multiples 10 and 5 would not have a factor of 12. A single mystery number would not have a sum of 6. Under these conditions, the mystery number will remain a mystery.

Let's break down the information given: "The mystery number is prime." This means the mystery number is a prime number. "The number one less than the mystery number has factors 2 and 9." This implies that (mystery number - 1) has factors 2 and 9. In other words: (mystery number - 1) = 2 * 9 (mystery number - 1) = 18 Now, let's solve for the mystery number: mystery number = 18 + 1 mystery number = 19 "The number two more than the mystery number is a multiple of 5." This means (mystery number + 2) is divisible by 5. In other words: (mystery number + 2) is divisible by 5 Let's check if 21 (19 + 2) is divisible by 5: 21 ÷ 5 = 4 with a remainder of 1 Since 21 is not evenly divisible by 5 (there is a remainder of 1), the statement is false. So, the mystery number is 19, which is a prime number, but the number two more than the mystery number (21) is not a multiple of 5.
The mystery number is less than one (a fractional number).
10:18 or 5:9 (simplified)

the answer is 528
