• A. If the data in statement I alone are sufficient to answer the question while the data in statement II alone are not sufficient to answer.
• B. If the data in statement II alone are sufficient to answer the question while the data in statement I alone are not sufficient to answer the question.
• C. If the data either in statement I alone or in statement II alone are sufficient to answer the question.
• D. If the data even in both statements I and II together are not sufficient to answer the question.
• E. If the data in both statements I and II together are necessary to answer the question.

Answer 1

Answer: (B)

If the data in statement II alone are sufficient to answer the question while the data in statement I alone are not sufficient to answer the question.

Given, the first day of month is Thursday.

Statement 1 doesn't give any additional information, it can be calculated from the given condition itself.

Statement 2 provides leads us to answer.

Thursday is the 1st day(given). So first saturday will be on 3rd day. And 5th saturday i.e 4 more weeks from 3rd day = 3 + 4*7 = 31 days.

Since this 5th saturday is the last day of month, there were 31 days in the month.

Hence, Option B is correct, data in statement 2 alone is sufficient to answer the question but data in statement 1 alone is not sufficient.
