Two newspapers \( A \) and \( B \) are published in a city. It is known that \( 25 \% \) of the city populations reads \( A \) and \( 20 \% \) reads \( B \) while \( 8 \% \) reads both \( A \) and \( B \). Further, \( 30 \% \) of those who read \( A \) but not \( B \) look into advertisements and \( 40 \% \) of those who read \( B \) but not \( A \) also look into advertisements, while \( 50 \% \) of those who read both \( A \) and \( B \) look into advertisements. Then the percentage of the population who look into advertisement is [JEE (Main) 2019] \( \begin{array}{ll}\text { (a) } 12.8 & \text { (b) } 13.5 \\ \text { (c) } 13.9 & \text { (d) } 13\end{array} \)
