Best answer
Correct Answer - Option 1 : 85

Given:

A student scored 86, 92, 77, 95 and 75 marks out of 100 in five subjects.

Formula used:

Average Marks = sum of marks in all subject/number of subject

Calculation:

Sum of all marks in five subject

⇒ 86 + 92 + 77 + 95 + 75

⇒ 425

Number of subject is 5

Average marks 

⇒ 425/5

⇒ 85

∴ Average marks in all five subject is 85.
