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.

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?
