Explanation

Because the problem never indicates real values, pick your own smart numbers. If x = 100 and y = 50, then:

Greta’s salary was $100,000 and she received a 50% raise. Greta’s raise, therefore, was$50,000.

Annika’s salary was $50,000 and she received a 100% raise. Annika’s raise, therefore, was$50,000.

The two quantities are equal. This holds true for any positive numbers chosen for x and y, because x percent of y = y percent of x. Thus, any two numbers can be used—just as 50% of 100 = 100% of 50, it is also true that 1% of 2,000 = 2,000% of 1, or a% of b = b% of a.

Hence option C

x, y >= 1, integer
Quantity A = xy%
Quantity B = yx%
--> A = B

Just for my better understanding : the question says " y raise or x raise", NOT x percent or y percent raise. The raise maybe in whole figure ( say y=300 dollar raise or y=400 dollar raise), instead of x% or y% raise, is not it? Please help somebody with some explanation. Thanks in advance .

If your salary is 100 and then the increase is 10, then you do have $10 more. But still, it is a 10% increase. The two things overlap. It is not specified in the stem. In this particular case, we can hand it as % also. Hope is clear now.

No, unfortunately it is still not clear. How about we would not assume that there are percents?

Then Greta had $100 000, raise was 50 000, => raise was 50 000; Annika had$50 000, raise was \$100 000 => raise WAS 100 000.

What exactly am I missing? Where is this mysterious thing which is obvious for the rest of us?

I agree with leanyanko
y raise means a constant number, in this case the answer will be "D"

You are all correct to question the veracity of the official answer.
I have edited the question to show that we are raising the salaries by y and x PERCENT.

Cheers,
Brent

This doesn't make sense to me...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
