Question: 1 / 400

A class of students has an average age of 12 years. If there are 20 students, what is their total age?

240 years

To find the total age of the students in the class, we can use the formula for average, which is the total sum of ages divided by the number of students. We know the average age is 12 years, and there are 20 students in the class.

The formula for average can be rearranged to find the total age:

Total Age = Average Age × Number of Students

Substituting in the given values:

Total Age = 12 years × 20 students = 240 years

Thus, the total age of the students is 240 years. This calculation shows how averages work in calculating totals by multiplying the average by the number of participants, which confirms that the correct answer is based on applying this mathematical concept accurately.
