Step 1: Understanding the Concept:
Identify all even numerals (0, 2, 4, 6, 8) present in the digits of each number in the range [291, 300].
Step 2: Detailed Explanation:
List the numbers and their even digits:
- 291: 2 (1)
- 292: 2, 2 (2)
- 293: 2 (1)
- 294: 2, 4 (2)
- 295: 2 (1)
- 296: 2, 6 (2)
- 297: 2 (1)
- 298: 2, 8 (2)
- 299: 2 (1)
- 300: 0, 0 (2)
Step 3: Calculation:
Total count = $1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 = 15$.
Wait, re-checking the "even numerals" count:
In 291-299, the digit '2' appears 9 times.
In 292, 294, 296, 298, the units digits (2, 4, 6, 8) add 4 more.
In 300, '0' is an even numeral, appearing twice.
Total: $9 + 4 + 2 = 15$.
Self-correction: Looking at the options, if 15 is listed as (C), let's verify. My manual count is 15.
Step 4: Final Answer:
The total count of even numerals is 15. Thus, the correct option is (c).
