The answer is '28'.
Largest three digit number is 999 and we see that it is odd. One less than that is 998 and it is even and it is also three digits. No other 3 digit number is larger than 998 while being even.
To determine the number of even 2-digit whole numbers less than 50 using the digits 1-9, we need to consider the possible combinations. The even digits are 2, 4, 6, and 8. For the tens place, we can choose any digit from 1-4 (since we want numbers less than 50). For the units place, we can choose any of the even digits. Therefore, there are 4 choices for the tens place and 4 choices for the units place, resulting in a total of 4 x 4 = 16 even 2-digit whole numbers less than 50 using the digits 1-9.
4,998 of course !
98. It's less than 100, and 9 + 8 = 17
16 maybe.=)
754 Piece of cake!
The number can be any one of these four numbers:640751862973

AB If B = x, then A = x + 4 Also, A = 2x -1 So that, 2x - 1 = x + 4 x = 5 B = 5, A = 9 So AB = 95

998-5=993

The secret number must be a two-digit number greater than 25 and less than 50. Since the tens digit is odd, it can be 3, 5, or 7. However, the sum of the digits must be less than 10, so the only possible tens digit is 3. The units digit can be any number from 0 to 9 that, when added to 3, results in a sum less than 10. Therefore, the secret number is 31.
