Let $a_i = i + \frac{1}{i}$ for $i = 1, 2, \ldots, 20$. Let $p = \frac{1}{20} \sum_{i=1}^{20} a_i$ and $q = \frac{1}{20} \sum_{i=1}^{20} \frac{1}{a_i}$. Then,
- A$q \in \left(0, \frac{22-p}{21}\right)$
- B$q \in \left[\frac{22-p}{21}, \frac{2(22-p)}{21}\right)$
- C$q \in \left[\frac{2(22-p)}{21}, \frac{22-p}{7}\right)$
- D$q \in \left[\frac{22-p}{7}, \frac{4(22-p)}{21}\right)$
