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.

24680 using only even numbers or 12346 which is an even number
Assuming the question refers to the digits 1, 2, ... , 9 the answer is 1344 numbers.
Try 130. Or how about 310.
9650 is the largest formed by re-ordering the digits.
456, 546 and 564 are three of the four possible even numbers.
None, because you do not have three even digits. None, because you do not have three even digits. None, because you do not have three even digits. None, because you do not have three even digits.

To find the even two-digit numbers where the sum of the digits is 5, we need to consider the possible combinations of digits. The digits that sum up to 5 are (1,4) and (2,3). For the numbers to be even, the units digit must be 4, so the possible numbers are 14 and 34. Therefore, there are 2 even two-digit numbers where the sum of the digits is 5.
