• C. If the data either in statement I alone or in statement II alone are sufficient to answer the question
• D. If the data given 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

The correct option is A

If the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question

From statement I, we conclude that there are 16 students and 11 boys taller than Shravan. This implies that there are 5 girls taller than Shravan.

In statement II, Shravan's rank from the bottom is mentioned and to ascertain the number of girls taller than him, we need to know his rank from the top for which the number students in the class is required, which is not given.
