i am not sure i understand the question properly. does it mean the # will be greater than 50 or not or sum of two digits will be greater than 50 or not. If it is by # it self, 99 is greater than 50, but I think 42 works as well. 4+2=6 is multiple of 18 and 42 less than 50.

6 is NOT a multiple of 18, it's a factor of 18.

Hi Bunuel

As always super helpful on your explanations

MY question is the following:

Assuming that 1 is a multiple of all integers, couldn't statement 1 also be interpreted as:

x+Y=1 X=1 Y=0 ->number is 10 (which is a 2 digit positive number and respects the premises)

Since there is no restriction of XorY being non zero, other than together must for a two digit integer, this option should be contemplated and therefore statement becomes invalid (an actually correct answer would be E)

What do you think?

Thank you very much,
