In some questions, I am often facing the following wording:
"x is number that is evenly divisible by 1/2".
The expression a is Divisible by b means a = kb for some integer k. The evenness is already embedded in this expression as a = kb means k parts of equal size, b. Emphasising the evenness is not needed.
So in my view, this adjective if deliberately added should be interpreted as the quotient being even. It goes without saying that 1/2 always divides any integer with an even quotient. In other words, this question meant x is always an integer.
But the solution provided to this question interpreted this merely as "leaves no remainder". It went on to take x = 1.5 and drew some conclusion out of it. I am worried as to what exactly is the difference between divisible and evenly divisible. Does it matter on the D-day at all?
Can some gurus comment please?

Not a single question in OG12 that uses "evenly divisible". All of them just use "divisible". Guess GMAT doesn't like to confuse people with unnecessary adjective like this one, at least not in quantitative.
Also, I think "evenly divisible" just means "divisible"- "No remainder" and the quotient should be an integer.
Let's see what others think!!
BTW, what is the source of this question?
