February 2024 is a leap year, so it has 29 days.
Using Statement I: The first Tuesday fell on 6th.
If the first Tuesday is on the 6th, subsequent Tuesdays occur every 7 days:
Tuesdays: 6th, 13th, 20th, 27th
Since February 2024 has 29 days, we check if there's another Tuesday after the 27th:
27+7=34>29
The last Tuesday of February 2024 is the 27th.
Statement I alone is sufficient.
Using Statement II: The last day (29th) was Thursday.
Working backwards from February 29th being Thursday:
- February 28th: Wednesday
- February 27th: Tuesday
- February 26th: Monday
Since 27+7=34>29, there is no Tuesday after the 27th.
The last Tuesday of February 2024 is the 27th.
Statement II alone is sufficient.
Since the data in either statement I alone or statement II alone is sufficient to answer the question, the correct answer is Option 4.
