उत्तर
\[ \text{ It is given that Neha types 75 pages in 14 hours } . \]
\[ \therefore \text{ Number of pages typed by her in 1 hour } = \frac{75}{14}\]
\[ \therefore \text{ Number of pages typed by her in 20 hours } = \left( \frac{75}{14} \times 20 \right) \text{ pages } \]
\[ = \frac{1500}{14} \text{ pages } \]
\[ = \frac{750}{7} \text{ pages } \]
\[ = 107\frac{1}{7} \text{ pages } \]
\[\text{ Thus, Neha types } 107\frac{1}{7} \text{ pages in 20 hours } .\]
