Korolek [52]

Answer: $52 years$

Step-by-step explanation:

The formula for calculating mean = sum of each data / total number

Let the age of the sixth person be x , then

mean = 23 + 13 + 17 + 12 + 15 + x / 6

That is :

22 = 23 + 13 + 17 + 12 + 15 + x / 6

22 = $\frac{80+x}{6}$

$80+ x$ = 22 x 6

$80 + x = 132$

$x = 132 - 80$

$x = 52$
