Answer 2

Given,

The ages of four friends are 42, 44, 46, and 48 respectively.

To find,

The average age of the four friends.

Solution,

We can simply solve this mathematical problem using the following process:

Mathematically,

The average of a set of given data can be calculated as follows;

Average = (sum of all the observations)/(total number of observations){Statement-1}

Now, according to the question and statement-1;

The average age of the four friends

= (sum of all the observations)/(total number of observations)

= (sum of the ages of all four friends)/(total number of friends)

= (42+44+46+48)/4

= 180/4 = 45

Hence, the average age of the four friends is equal to 45 years.
