Solution

If you count the number of hours, it is as follows:

$\begin{matrix} E n g l i s h & 5 \times 2 = 10 h o u r s M a t h e m a t i c s & 7 \times 2 = 14 h o u r s P h y s i c s & 4 \times 2 = 8 h o u r s C h e m i s t r y & 3 \times 2 = 6 h o u r s B i o l o g y & 4 \times 2 = 8 h o u r s \end{matrix}$

So, Mathematics takes the most time and Chemistry takes the least time.
