Answer:
Option A (89).
Step-by-step explanation:
Percentile is a statistic in which the an element at a certain percentage position is determined. To calculate the percentiles accurately, it is important that the data is present in the ascending order. Percentile is an important concept in data analysis. Interestingly, 50th percentile is the median of the data. The difference between the 75th and the 25th percentile is the interquartile range. To find the 85th percentile of the data, calculate 85% of 40, which is the number of elements in the data set. 40 * 85/100 = 34. The number on the 34th position is the 85th percentile of the data. It can be observed that 89 is on the 34th position. Therefore, Option A is the answer!!!

In a class of 28 students the ratio of girls and boys is 4:3. The number of girls in the class is 16.
Solution:
Let us consider total number of students in the class is “T”.
Let the ratio of the students (Girl and boys) in the class is G: B.
Given that total number of students in class (T) = 28
From question, given that ratio of girls and boys is 4:3. We can write this ratio as,
Number of girls (G) = 4x and number of boys (B) = 3x
We have to find the number of girls in class. The total number of girls present in the class is given as ,
The total girl students present in the class G =
=
Hence the total number of girls in the class is 16.
4x7=28
16 are girls and the balance is 12 boys
