Using the data given in the statements, plus your knowledge of mathematics and everyday facts, you must indicate whether:

  • Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.

  • Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.

  • BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.

  • EACH statement ALONE is sufficient to answer the question asked.
