Greta’s salary was x thousand dollars per year

Greta’s salary was x thousand dollars per year, then she received a y% raise. Annika’s salary was y thousand dollars per year, then she received an x% raise. x and y are positive integers.

Quantity A : The dollar amount of Greta’s raise

Quantity B : The dollar amount of Annika’s raise

The answer says C, as we know x% of y == y% of x

but,
I thought the answer was D. Please correct me where I am wrong.

If x = 30 and y = 10
x+y% raise = 30 + 10% = 33
y+x% raise = 10 + 30% = 13.

I can also do this for x=200 and y=2
200+2% raise = 202
2 + 200% raise = 6

Hey,

Read carefully, both option A and B are asking for amount of raise. While you are answering total salary after raise.
