Manhattan 5lbs Normal dist and standard deviation

[hasibul212003]

Hello can anyone help me how to proceed with the following sum
37. 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


TIA
