Smallest 4-digit number whose digits sum up to 15?
-11
How many 3 digits whole numbers whose sum is 3?
There are no 3-digit whole numbers whose digits sum to 3. The smallest 3-digit number is 100, and the largest is 999, but in neither case is the sum of the digits equal to 3.
What is the only number whose value is twice the sum of its digits?
18
What is the sum of positive six digit integers whose digits are a permutation of the digits in the number 123456?
279,999,720
What is the number that is 1 less than the number whose digits have a sum of 12 and whose tens digit is greater than 4 but less than 6?
56. Tens digit is greater than 4 and less than 6 so it can only be 5, so the number is 5X. It is one less than the number whose digits sum to 12, so its digits sum to 12-1 = 11 → 5 + X = 11 → X = 11 - 5 = 6 → the number is 56.
How many numbers are there whose digits sum to 4?

How many 3-digit numbers can you find whose digits have a sum of 4 list them?
-1
How many integers between 300 and 500 have the sum of their digits equal to A?
There are 3 whose sum is 45 whose sum is 57 whose sum is 69 whose sum is 711 whose sum is 813 whose sum is 915 whose sum is 1017 whose sum is 1119 whose sum is 1219 whose sum is 1317 whose sum is 1415 whose sum is 1513 whose sum is 1611 whose sum is 179 whose sum is 187 whose sum is 195 whose sum is 203 whose sum is 211 whose sum is 22.
What are the consecutive even integers of whose sum is 264?
There is no pair of consecutive even integers whose sum is 264 - as their average is divisible by 4, that must mean that the sum of the unit digits of each of the pair of numbers could never be a multiple of 4 - which 264 is.
How many 5 digits numbers are there whose digits sum to 22?
There are 5460 five digit numbers with a digit sum of 22.
How many 3 digits whole numbers whose sum is 3?
There are no 3-digit whole numbers whose digits sum to 3. The smallest 3-digit number is 100, and the largest is 999, but in neither case is the sum of the digits equal to 3.

What is the sum of positive six digit integers whose digits are a permutation of the digits in the number 123456?
279,999,720
What is the smallest prime number whose sum of its digits forms a number that is a perfect cube?
I think it will be 17. The sum of digits is 8, which is the cube of 2.
What is the number that is 1 less than the number whose digits have a sum of 12 and whose tens digit is greater than 4 but less than 6?
56. Tens digit is greater than 4 and less than 6 so it can only be 5, so the number is 5X. It is one less than the number whose digits sum to 12, so its digits sum to 12-1 = 11 → 5 + X = 11 → X = 11 - 5 = 6 → the number is 56.
What three digit number whose digits are all odd and different has a sum of the three digits that is palindromic?
137?
