X is a two-digit number. The digits of X differ by 6 and their squares differ by 60.
Which is bigger?
A) X
B) 60
When you solve this, you'll get that the first no. is 8 and 2nd is 2, making the number 82. The OA however says it can be 82 or 28...is he treating 6 as an absolute value? cause 2-8 isn't = 6

Difference between two number is equal to (larger - smaller) and thus always positive.
For example in this case, difference of 2 and 8 is same as difference between 8 and 2 and equal to 6. Thus whenever you have to represent the difference between two number x and y as an equation, you must write their difference as |x - y| as you don't which one is larger.
