Given,

Age of Athiyan $\[ = p\]$

Mugilan is elder to Athiyan by 5 years.

Solution,

Consider the age of Athiyan and Mugilan is p and q respectively.

write an algebraic statement for this ?

$\[q = p + 5\]$

Find the age of Mugilan if Athiyan is 10 years old.

$\[p = 10years\]$

$\[\begin{array}{l}q = p + 5\\ \Rightarrow q = 10 + 5\\ \Rightarrow q = 15years\end{array}\]$

Hence the age of Mugilan is 15 years.
