The total number of integers between 200 and 400, each of which either begins with 3 or ends with 3 or both, is
-
- 10
- 100
- 110
- 120
- 10
Correct Option: C
When 3 lies at hundreds place
∴ Total integers = 10 × 9 = 90
When 3 lies at units place
Total integers = 10
When 3 lies at unit’s and hundred’s place
Total integers = 10
∴ Total integers = 90 + 10 +10 = 110
