• A. If the data in statement I alone are sufficient to answer the question,while the data in statement II alone not sufficient to answer the question;
• B. If the data in statement II alone are sufficient to answer the question,while the data in statement I all 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

The correct option is D If the data even in both statements I and II together are not sufficient to answer the question;

From statement I:

Number of girls behind Mita can not be determined. Hence, total number of girls can not be calculated.

From statement II:

If total number of girls is not known, total number of boys can not be determined. Therefore, statement II is of no use.

Hence, both statements together are not sufficient to answer the question.

Hence, D is the correct option.
