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

Answer 1

Answer: (D)

If the data even in both the statements together are not sufficient to answer the question

From given statements,

we find that Kajal + Tanmay > Suman and Rohit + Kajal < Suman.

so we can conclude that

Suman > Rohit and Suman > Kajal

but we do not know who is older between Suman and Tanmay

so we cannot answer the question

so option D
