The average marks of a student in 6 subjects are 75. If the student scores 80 in one subject, what will be the total score in the remaining subjects.

Correct option is A

Given:
Average marks = 75, Marks in one subject = 80.
Formula Used:
Total Score = Average * Number of subjects.
Solution:
Total score = 75 * 6 = 450
Total in remaining subjects = 450 - 80 = 370.
