x,y , and z are positive integers. Is x% of y bigger than y% of z ?

1: x=z

2: z-y =y-z

Answer?

* Can we assume x=y=z for eqation 1..just one more case?

Thanks

x % of y = xy/100

y% of z = yz/100

question is asking is (xy/100) > (yz/100) ?

or is xy > yz

we know x,y and z are +ve

so the question can be simplified to is x>z ?

(1) tells us x=z . that means x is not > z. So sufficient.

(2) no infor about x and z. Not suff.

Answer is A ?

P.S. I don't get your question reg x=y=z
