Percentile divides the data into how many equal parts-
Ans. is 'd' i.e., Hundred Division of distributions* Distributions can be divided into multiple equal parts by various measures of location. For example a Quartile divides the distribution into four equal parts (25% each).* So, in Quartile the number of intercepts required are three : Q1 (first/lowest quartile), Q2 (second quartile) and Q3 (third/highest quartile).* Similarly tertile divides the distribution into three equal parts (33.33% each) by two intercepts.

So, number of interception required are 99, i.e., there are a total of 99 percentiles. Median is 50th centile. n percentile implies that (n - 1)% of values are below it and (100 - n)% of values are above it e.g. 40th percentile means 39% (n - 1 = 40 - 1) values are below it and 60% (100 - n) values are above it.
