(I) Each male earns Rs 1,250 a month and each female earns Rs 1,050 a month.
(II) Ratio of males to females in the family is 2 : 1

• A. Statement (I) ALONE is sufficient, but statement (II) alone is not sufficient
• B. Statement (II) ALONE is sufficient, but statement (I) alone is not sufficient
• C. BOTH statements TOGETHER are sufficient, but NEITHER statement alone is sufficient
• D. EACH statement ALONE is sufficient

Answer 1

The correct option is C BOTH statements TOGETHER are sufficient, but NEITHER statement alone is sufficient

I) ⇒M=1,250⇒M=1,250 and F=1,050F=1,050
(II) ⇒M:F=2:1⇒M:F=2:1
Combining both the statements, we get
Average=2K×1250+K×10503KAverage=2K×1250+K×10503K
⇒⇒ Both statements together are sufficient to answer the question.
