Q:

The ratio of volume of a cone to that of a cylinder if cylinder radius is reduced by 4 times and its height increased by 8 times of that of the cone, is - 

A) 3:2 B) 2:3
C) 5:7 D) 7:5
 
Answer & Explanation Answer: B) 2:3

Explanation:

Ans. Let radius of the base and height of the cone be ‘r’ & ‘h’ respectively.

Then volume of cone = πr2h/3 For cylinder, radius is reduced by 4 times = r/4 And,  height is increased by 8 folds = 8h Volume of cylinder = πR2H = π(r/4)2 (8h) = (16/8)πr2h = πr2h/2 Ratio of volume of cone to volume of cylinder = (πr2h/3) : (πr2h/2) Or, Ratio = 2 : 3.

Statement:
Y > A < N, Y = B <P
Conclusion:
I. P > A
II. N > B

A) If only conclusion I follow. B) If only conclusion II follow.
C) If either conclusion I or conclusion II follows. D) If neither conclusion I nor II follows.
 
Answer & Explanation Answer: A) If only conclusion I follow.

Explanation:

Y > A < N, Y = B <P
P > B = Y > A < N
For conclusion I -
P > B = Y > A
P > Y > A
I. P > A (True) P is greater than A is true.
For conclusion II -
B = Y > A < N
II. N > B (false) There is no relation between N and B.
Hence, only conclusion I follow.
