Three numbers that fit these criteria are:
108, 144, and 180.
there is no number less than 49 between 1 and 100 that if multiplied by 2 will have a 3-digit product no number less than 50, actually
160, 250
No. (Assuming a three digit number is in the range 100-999 and excludes leading zeros, that is 080 does not count as it is really 80 which is a two digit number) To be divisible by 11, the difference in the sums of the alternate digits of the number must be divisible by 11 (or 0). For a three digit number, this means that the sum of the first and last digits less the second digit must be a multiple of 11 (or 0). For a three digit number with all the digits the same, this calculation results in the value of one of the digits (eg 333 → 3 + 3 - 3 = 3) which will not be 0, and cannot be a multiple of 11 as a single digit is less than or equal to 9 which is less than 11 and thus not a multiple of 11.
There are 278 5-digit numbers less than 20,000 that are divisible by both four and nine.
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?

When the last digit is zero. All whole numbers of more than one digit and with a last digit of 0, 2, 4, 5, 6 or 8 are divisible by another number. Numbers ending with the other digits, 1, 3, 7 and 9, might be divisible by another number, and they might not.
