Hi,
Suppose every one on the tests gets 175. Then 175 falls in all the 100 percentile groups.
And all the other integers have no percentiles attached to it.
So Quantity A: 1
Quantity B: 0
Hence Quantity A is greater.
Regards

Thanks for the explanation Sandy.
I may not have understood the question completely, so I don't get your explanation.
What if we suppose everyone gets a 200. Then doesn't that mean "D" should be the answer?
