W and x are whole numbers. 11 > 40
x < 30
D
Work out the smallest possible value of
11 – X

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

Here for a good time of free question aha
