I cant remember the wording exactly.

X is equal to Y plus 40%. Z is equal to Y less 20%.

X = y + 40% or x = 1.40y

Z= y - 20% or z = 0.80y

One tends to say % of something. Percent by itself does not have
any meaning. Given the above, I'm inclined towayds 1.4y and .8y

ya this was my first question on the gmat

I cant remember the wording exactly but it had me confused for some reason and I used x = y + 0.40 when I suspect it should have been x = 1.40y. Because when I solved for the problem my answer choice didnt show up!! This eventually led to my downfall in the math section!
