Question

Find the smallest positive whole number that when multiplied by 999 does not contain a 9 as one of its digits.

Answer 1

I checked up to 40 for you. Just take a calculator (I used the computer calculator) and do 999 x 41, 999 x 42 and so on until you get no 9's in your answer.

Answer 2

I had success at 999 x 112, by going through them one at a time. I might have missed one along the way.
