63 How did you get this answer? The tens digit must be six. The ones digit must be half that, therefore three.
21 ================ 21 doesn't satisfy the conditions at all, since you can't get ' 1 ' by doubling ' 2 '. I'll suggest that you can be either 12 or 24 .

That means multiply it by 2. If your tens digit is 3, your ones digit is 6.

3 more than 5 is 8, so the tens digit is 8. The tens digit is,double the number of the ones digit, so divide 8 by 2 and you get 4. If you double 4 it is 8 so, the number is 84.

If you can ask this question, the answer is obvious. Between the ages of 41 and 49, the only age where the 4 (tens digit) is twice the ones digit is at age 42. Four is two doubled you know....
How about 63 which would comply with the given criteria.
I am a four digit number. My tens digit is 2 more than my ones digit. My hundreds and thousands digit are both 1 less than my ones digit. What number can i be?
