Question

A student obtained the marks 16,50,70,65 and 85 in subjects a, b, c, d and e. What would be the average marks?​

Answer 1

Answer:

57.2

Step-by-step explanation:

The sum of the numbers divided by the total number of values in the set.

16+50+70+65+85 = 286

Then

286/5 = 57.2

Therefore the average mark is 57.2

Answer 2

Given:

A student obtained the marks 16,50,70,65 and 85 in subjects a, b, c, d and e.

To find:

What would be the average marks?​

Solution:

• To find the average marks, first, add the given numbers. Then, divide it by a total number of values.

Sum of the given observations:

$16+50+70+65 + 85$

$= 286$

Now, divide it by a total number of observations:

The total number of observations = 5

$= \dfrac{286}{5}$

$= 57.2$

Hence, the average marks = 57.2
