Solve this : 36% of 365 + (?)% of 56.2 = 156.69

Answer: Option D

Let 36% of 365 + x% of 56.2 = 156.69
Then,
$$\Rightarrow \left(\frac{36}{100}\times 365\right)+\left(\frac{x}{100}\times 56.2\right)$$       $$=156.69$$
$$\begin{array}{rl}& \Rightarrow \frac{281}{500}x=156.69-131.4\\ & \Rightarrow \frac{281}{500}x=25.29\\ & \Rightarrow x=\frac{25.29\times 500}{281}\\ & \Rightarrow x=45\end{array}$$
