    1. Since Section A has 30 students and Section B has 25 students, their different class sizes require a weighted average rather than a simple mean. Multiplying each section’s average by its student count gives total scores of 2160 and 1900, totaling 4060 marks. Dividing this total score by all 55 students results in an overall combined test average of approximately 73.82 for both sections.
