Data sufficiency: On what day of the week was Lito born? (1) He was born on June 12. (2) He is 30 years old today. Which of the following is correct?
- Statement (1) ALONE is sufficient, but statement (2) alone is not.
- Statement (2) ALONE is sufficient, but statement (1) alone is not.
- BOTH statements TOGETHER are sufficient, but NEITHER alone is.
- The statements are NOT sufficient, even when taken together.
Answer
D. The statements are NOT sufficient, even when taken together.
Solution
The answer is: The statements are NOT sufficient, even when taken together. Even together, the birth year depends on today's date (whether his birthday has passed this year), which is not given, so the day of the week cannot be determined — not sufficient.
