Consider the following distribution:
\( \mathrm{P} \)
\begin{tabular}{|c|c|c|c|c|c|}
\hline Class & \( 0-5 \) & \( 5-10 \) & \( 10-15 \) & \( 15-20 \) & \( 20-25 \) \\
\hline Frequency & 10 & 15 & 12 & 20 & 9 \\
\hline
\end{tabular}
W
The sum of the lower limits of the median class and the modal class is
(a) 15
(b) 25
(c) 30
