Hint: Assume Ravi’s age is some variable and then form a linear equation to determine his age by solving it.

Let Ravi’s present age is $x$ years old.
Then after fifteen years, his age will be $\left( {x + 15} \right)$ years old.
According to the question, after fifteen years, Ravi’s age will be four times his present age. Then we have:
Age after $15$ years $ = 4 \times $Present Age,
$
   \Rightarrow \left( {x + 15} \right) = 4x, \\
   \Rightarrow 4x - x = 15, \\
   \Rightarrow 3x = 15, \\
   \Rightarrow x = 5 \\
$
Therefore, Ravi’s present age is $5$ years old.
Note: Convert the given problem statement in the form of a linear equation in one variable and then simplify to determine the required value.
