Correct answer
39
Why this answer is correct
Given:
Average marks of the group (5 students) = 27
Average marks of the remaining group (4 students) = 24
Formula Used:
Sum of marks of all students = Average × Number of students
Sum of marks of remaining students = Average × Number of students
Marks scored by Akash = Sum of marks of all students - Sum of marks of remaining students
Calculation:
Sum of marks of all students = 27 × 5 = 135
Sum of marks of remaining students = 24 × 4 = 96
Marks scored by Akash = 135 - 96 = 39
The correct answer is option 2.
