The sum of my ones digit and tens digit is also 10. However, my ones digit is greater
than my tens digit. I am a prime number less than 30. What number am I?
really? There are only a few candidates:
19, 28, 37, 46
see any primes less than 30 in that list?
your number must be less than 30
if the unit digit and the tens digit add up to 10
your number is one of 28 or 19
Now, which of those is prime???
To find the number that satisfies the given conditions, we need to analyze the information provided step by step.
First, let's note that the ones digit is greater than the tens digit, so we are looking for a number in which the ones digit is larger.
Next, we know that the sum of the ones digit and tens digit is 10. This means that the ones digit and tens digit must add up to 10.
Now, let's consider the prime numbers less than 30. We can quickly list them: 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29.
Among these prime numbers, only a few satisfy the condition that the ones digit is greater than the tens digit and their sum is 10. By checking each prime number, we find that the only number meeting these criteria is 23.
Therefore, the answer is 23.
