A child scored 75 marks in each of five subjects. What is the median marks obtained by the child?

The correct answer is 75.

Step-by-step Explanation:

1. Understand the Data:
The marks scored by the child in the 5 subjects are listed as follows:
75, 75, 75, 75, 75

2. Definition of Median:
The median is the middle value in a set of ordered data. When the number of observations, $n$, is odd, the median is given by the position:
$\left(\frac{n+1}{2}\right)$-th term.

3. Calculate the Median Position:
Here, total number of subjects $n=5$ (which is odd).
Median term position $=\frac{5+1}{2}=3$-rd term.

4. Find the Value:
Arranging the dataset in ascending order gives: 75, 75, 75, 75, 75.
The 3rd term in this ordered list is 75.

Therefore, the median marks obtained by the child is 75.
