Task Solution: Finding the Number of Pages Occupied by Illustrations

To solve this problem, we can use the given information that 90% of the encyclopedia's 2400 pages are stories about animals, and the rest are illustrations. We'll calculate the number of pages occupied by illustrations using this information.

Given: - Total number of pages in the encyclopedia: 2400 - Percentage of pages occupied by stories about animals: 90%

Calculation:

We can calculate the number of pages occupied by illustrations using the following formula:

Number of pages occupied by illustrations = Total pages * (Percentage of pages occupied by illustrations / 100)

Substituting the given values: Number of pages occupied by illustrations = 2400 * (10 / 100) Number of pages occupied by illustrations = 240

So, 240 pages are occupied by illustrations in the encyclopedia.

Therefore, the number of pages occupied by illustrations in the encyclopedia is 240 pages.
