Question

The marks obtained by Rama in seven subjects are 60, 53, 90, 65, 62,85 and 82. Find the average marks​

Answer 1

`Average = 71`

Explanation:

Given

Subjects = 7

Marks: 60, 53, 90, 65, 62,85, 82

Required

Determine the average mark

We start by adding the marks together.

`Sum = 60 + 53 + 90 + 65 + 62 + 85 + 82`

`Sum = 497`

Then divide the sum by number of subjects

`Average = (Sum)/(Subjects)`

`Average = (497)/(7)`

`Average = 71`

Hence, the average mark is 71
