Write a 3digit number that answer the riddle.I have the same hundreds digit as ones digit. The value of my digit is 50. The value of my ones digit is 4. The number is.......

The 3-digit number that answers this riddle is 504.

Here's how we arrive at this number:

1. The riddle specifies that the hundreds digit and the ones digit are the same. This means that the first and the third digits of the number must be identical.

2. The riddle states that the value of the hundreds digit is 50. Since we are dealing with a single digit in the place value, it must mean that the riddle intends to say the digit itself is 5, as no single digit can have a value of 50 in the hundreds place (the actual value would be 500, but we're interested in the digit only).

3. If the hundreds digit is 5, and because the ones digit is the same, the ones digit must also be 5.

4. Lastly, the riddle states that the value of the ones digit is 4. Since the ones place can only contain a digit and not a value like 50, this must mean that the second digit, or the tens digit, is 4.

Putting it all together, we have the hundreds digit as 5, the tens digit as 4, and the ones digit as 5, making the number 504.
