Manhattan 5lb Ch22 (Normal Distribution) --- Question 36

Manhattan 5lb 1st edition--Ch22 (Normal Distribution) --- Question 36 (percentile & quartile)

The outcome of a standardized test is an integer between 151 and 200, inclusive. The percentiles of 400 test
scores are calculated, and the scores are divided into corresponding percentile groups.

Quantity A

Minimum number of integers between 151 and 200,
inclusive, that include more than one percentile group

Quantity B

Minimum number of percentile
groups that correspond to a score of
200

I didn't understand the explanation of the book. Can someone explain lucidly, how to find percentile and percentile group based on the info the question ?

This question has been addressed before in the forum. Please always check before posting a new thread. (Also, I believe it's question 37, unless there's been some change in the order of the book at some point I'm unaware of.)
