DIRECTIONS for the question: The question below is followed by two statements marked I and II. Mark as your answer.
A right circular cone (PQR) is cut into two parts, cone (C) and frustum (F) by a plane parallel to base. What is the ratio of volume of C to the volume of F?
Statement 1: PQR is twice the radius of C
Statement 2: PQR is been cut off at the middle of its height
A)
If the data in statement (1) alone is sufficient to answer the question
B)
If the data in statement (2) alone is sufficient to answer the question
C)
If the data in both the statements together are needed to answer the question
D)
If either statement (1) alone or statement (2) alone is sufficient to answer the question
E)
If neither statement (1) nor statement (2) suffices to answer the question
D
from statement1- the radius will be in ratio of 1:2, & hence volume in ratio of 1:8.
same for statement 2.
