how many natural numbers have 20 as their digit's quotient and 11 as their digit's number??

Answer 1

If their digit's number means the sum of the digits, then there are lots of them.

But if since a quotient is only defined for two numbers, that implies that the number is a 2-digit value.

I can't think of any two digits whose quotient is 20 and whose sum is 11.

I suspect you have garbled the question.
