Question

The ages of $5$ children are $13,15,11,9$ and $8$ years respectively. The average age is

• A. $10.2$
• B. $12.2$
• C. $11.2$
• D. $11$

Answer 1

Answer: (C)

$11.2$

Average is the sum of the data values divided by the total number of values.

Given that, $13,15,11,9,8$ are the ages of $5$ children.

Therefore, average age $=\frac{13+15+11+9+8}{5}=\frac{56}{5}=11.2$
