Solution

We need to figure out how long it would take to finish the quiz magazine in the shortest amount of time possible. As a result, we must solve as many numericals as possible per day.

The largest prime number less than 20 is 19.
From the multiplication table of 19 we know
$19 \times 5 = 95$

As a result, if we solve 19 numerical problems per day, we will finish the magazine in 5 days.
