- Let's assume the total number of students in the school is 100 for simplicity.

- Therefore, 60 students are boys, and 40 students are girls.

- 20% of the boys failed, so 80% of the boys passed. 80% of 60 boys gives us 48 boys who passed.

- 65% of the girls passed. 65% of 40 girls gives us 26 girls who passed.

- In total, 48 boys plus 26 girls passed the examination, which sums up to 74 students.

- Therefore, 74 out of 100 students passed the examination.

- This translates to 74% of the total number of students passing.

Thus, the correct answer is Option 3: 74.
