Let, the present age of Sachin be $a$ years.
Therefore, before years, the age of Sachin would have been $\left( {a - Y} \right)$ years which is given to be equal to $X$ years.
$\left( {a - Y} \right) = X$
$a = X + Y$
Therefore, his present age is $\left( {X + Y} \right)$ years.
His age after $4$ years will be present age plus $4$, which is $\left( {a + 4} \right)$ years,
Age= $\left( {X + Y + 4} \right)$
