Correct Answer is : if both the statements I and II together are not sufficient to answer the question and additional data is required.

if the statement 1 alone is sufficient to answer the question.

if the statement II alone is sufficient to answer the question.

if both the statements I and II are sufficient to answer the question but neither statement alone is sufficient.

if both the statements I and II together are not sufficient to answer the question and additional data is required.

Question : 2 of 200

Marks: +1, -0

OA=\sqrt{11}

B=(2,3)

if the statement 1 alone is sufficient to answer the question.
if the statement II alone is sufficient to answer the question.
if both the statements I and II are sufficient to answer the question but neither statement alone is sufficient.
if both the statements I and II together are not sufficient to answer the question and additional data is required.

Solution:

I. It gives no information about point B.

∴ I alone is not sufficient.

II. It gives no information about point A.

∴ II alone is not sufficient.

I & II. With

OA=\sqrt{11}

, the location of A with respect to B can’t be uniquely

determined. A can lie anywhere on the circle of radius

\sqrt{11}

∴ I & II together are not sufficient.
