Question

What is the ratio of volume of sphere to that of the cone?
I. Radius of the cone is twice that of the sphere.

II. Height of the cone is equal to the radius of the sphere.

• A. if the question can be answered by using any of the statements alone but not by using the other statement alone.
• B. if the question can be answered by using either of the statements alone.
• C. if the question can be answered only by using both the statements together.
• D. if the question cannot be answered.

Answer 1

The correct option is C if the question can be answered only by using both the statements together.

Option c

We need the ratio of both, radius and height, in order to find the ratio of the volume. Thus both the statements are required.
