  3. CBoth statements together are sufficient to answer the question, but neither statement alone is sufficient
  4. DBoth statements together are not sufficient to answer the question
Show answer

Answer: D

Statement I gives only the combined total of Neha and Vijay (two unknowns, not sufficient alone). Statement II relates Vijay and Anita, neither of which pins down Neha's monthly salary on its own. Even combining both statements, Neha's monthly salary cannot be uniquely determined, since the information about Anita does not connect back to Neha. Hence both statements together are not sufficient.
