Solution

The correct option is A 5
Given, the expression is $\frac{x y + 2 x}{x} .$
Taking 'x' common from the numerator, we get
$\Rightarrow \frac{x y + 2 x}{x} = \frac{x (y + 2)}{x} = (y + 2)$

Now substituting the value of $y$ in the above equation, we get,
$\Rightarrow \frac{x y + 2 x}{x} = (y + 2) = 3 + 2 = 5$
