Directions to Solve
Each of the questions given below consists of a question followed by three statements. You have to study the question and the statements and decide which of the statement(s) is/are necessary to answer the question.
1.
What is the capacity of the cylindrical tank? | |
I. | The area of the base is 61,600 sq. cm. |
II. | The height of the tank is 1.5 times the radius. |
III. | The circumference of base is 880 cm. |
Answer: Option
Explanation:
Capacity = 
r2h.
I gives, r2 = 61600. This gives r.
II gives, h = 1.5 r.
Thus, I and II give the answer.
Again, III gives 2r = 880. This gives r.
So, II and III also give the answer.
Correct answer is (E).

Using one and three we can be able to find only the radius.
So, using 2 can get h that is h=1.5r after getting height we can substitute in 1 or 3 and then finally we can substitute all in capacity.
So, using 2 can get h that is h=1.5r after getting height we can substitute in 1 or 3 and then finally we can substitute all in capacity.

Answer can't be D since I and III can't give the volume. Both gives the radius. We need height for volume.
