Answer: Option D

Solution(By Examveda Team)

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