Solution:-
There is a mistake in this question. The total students are 10 but the marks are given only of 9 students. So, I am solving this question assuming that the students are 9.
Let the marks of those students who scored less than 35 marks be a, b, c and marks of the students who scored more than 70 marks be x, y, z.
The ascending order of the marks = a, b, c, 39, 43, 51, x, y, z
Now,
Median = (n + 1)/2
= (9 + 1)/2
10/2 = 5
so, 5th observation is 43.
So, the median score of the whole group is 43 marks.
