You can't get six odd numbers to add to an odd number in this Universe, so...

a little creative thinking (= "cheating") is needed...

3 + 3 + 3 + 1 + 11 uses 6 digits and the sum is 21...

... if you want to be REALLY "creative", turn one of the nines upside down and you could have 6 + 5 + 5 + 3 + 1 + 1...

Q: 9999555533331111 whose 6 digits sum is 21?

this would be explained on the basis of two FACTS below....... sum of two odd numbers are always even and sum of to even numbers are also always even then how 6 odd numbers (consider 3 pairs, 9 5 3 1 being odd numbers) can make an odd number 21..!! SO SIMPLE Make your basics strong...

The two numbers whose sum is 58 and whose difference is 16 are 21 and 37.

Yes, yes, and no. 3- sum of digits must be multiple of 3. 6- sum of digits must be multiple of 3 and number must be even (multiple of 2). 9- sum of digits must be multiple of 9. (The sum of the digits here is 21.)
