• D. If the data 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 are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.

Statement I gives Raman's ascending position amongst boys and in class. Thus we can find out using this data how many girls are taller than him.
Statement II gives Raman's descending position amongst boys and in class. Thus we can find out using this data how many girls are shorter than him, but not taller.
Therefore, the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
