It is 3823.
How about 89
It is 275
When the tens digit is even and the units digit is 0, 4 or 8 or the tens digit is odd and the units digit is 2 or 6.
There cannot be a proper three digit number between 10 and 20. It must be a two digit number. If you consider a 2-digit number between 10 and 20, then its tens digit MUST be 1 and so MUST be odd. So most of this question is either wrong or irrelevant. Are you sure you have not cut and pasted bits from two questions?
I think the answer is 612!1 (tens digit) which is odd is half of 2 (hundreds digit) and the sum is (6+1+2=9).
Since the first digit cannot be zero, the possibilities are 1054, 1216, or 3034.
35 and 119.
Yes. When you're trying to find an odd or an even number, you always focus on the first digit of the number. For example, if it was "472842", no matter what, this is an even number. The first digit is the one that counts. So yes, it is an odd number.
456, because they are consecutive, 4+5+6 is equal to 15, which is smaller than 20 but larger than 10, and 5 (which is in the tens place) is odd. :)
If the last two digits are divisible by 4 then the number is divisible by 4. Thus, if the tens digit is even and the units digit is 0 or 4 or 8 OR if the tens digit is odd and the units digit is 2 or 6 then the number is divisible by 4.
Look at the last digit. If a number's last digit is even, the number is even. If the last digit is odd, the number is odd.
