Question

Is $\sqrt{x}=11$?
(I) Square of 11 is not equal to x.
(II) Square is $\sqrt{x}$ is not equal to the square of 11

• 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 D EACH statement ALONE is sufficient

(I) ⇒x≠112⇒x√≠11⇒x≠112⇒x≠11
(II) ⇒(x√)2≠112⇒x√≠11⇒(x)2≠112⇒x≠11
Hence, each statement alone is sufficient to answer the question.
