Solution

The correct option is C $3.6$
Given, $0.7 x + 2 (x - 3) = 0.2 x + 3$ .
$\Rightarrow 0.7 x + 2 x - 6 = 0.2 x + 3$ ...[By Distribution Law].

Transposing $x$ terms to one side, we get,
$\Rightarrow 0.7 x + 2 x - 0.2 x = 3 + 6$
$\Rightarrow 2.5 x = 9$
$\Rightarrow \frac{5}{2} x = 9$
$\Rightarrow x = \frac{2}{5} \times 9 = \frac{18}{5} = 3.6$ .

Hence, option $C$ is correct.
