Answer 2

Concept introduction:

Mathematical age problem is a type of problem where we have to find the age of an individual by solving the relation between them.

Given :

Here it is given that $X$ is two years older than $Y$ who is two times older than  $Z$.

To find:

We have to find the age of $Y$.

Solution:

According to the question,

$X=2+Y\\Y=2Z\\= > Z=Y/2$

Now putting the values

$X+Y+Z=27\\= > 2+Y+Y+Y/2=27\\= > 5Y/2=25\\= > Y=10$

Final answer:

Hence, the age of $Y$ is $10$.
