Question

My number has 2 hundreds the tens digit is 9 more than the ones digit what is my number?

Answer 1

2 hundreds = 200

9 more than the ones digit can't be over 9, because even if the ones digit is 1, you'll have 10 and we'd need to add that to the hundreds place. Therefore the ones place has to have a 0.

The number is 290.

Hope I was able to help. :)
