How many 9s are there between 1 and 100?
Correct answer: C. 19
- A. 10
- B. 11
- C. 19
- D. 20
Explanation
To find how many times the digit '9' appears between 1 and 100, we need to check both the units and tens places. In the units place, '9' appears in the following numbers: 9, 19, 29, 39, 49, 59, 69, 79, 89, which totals 10 occurrences. In the tens place, '9' appears in 90, contributing an additional count. Therefore, the total number of '9's from 1 to 100 is 10 (units) + 1 (tens) = 19. Hence, the correct answer is Option C (19). The other options are incorrect due to either undercounting or miscounting occurrences of '9'.

About Logical Problems
Logical problems present several conditions about people, objects, events or choices and require their possible arrangements to be tested. They cover constraint-based reasoning, rankings, matching, grouping, scheduling and elimination, with attention to the difference between a complete solution and a possibility that merely satisfies one condition.
