The answer is B.
Here's the logic: if a product increases and then decreases by the same percent, it's overall value will
decrease - because the decrease % is being taken from a
larger base. for example, if 30 is increased by 100% - that's 60, and if that's decreased by 100 we get 0 - less than the original!
Looking at the answers, 1) is inconclusive. it depends what the base is and how much larger x is than y.
ex' where the answer is yes: base=100, x=100, y=10 ==> new number 180>100. ex' where its no: x=100,y=90 ==> new number = 20< 100.
2) tells is y>x which means that the new number is
definitely smaller than the original. B is the answer
