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.

Q:

The Regent (released Voltaire) P (having discovered that he had imprisoned) Q (Ran innocent man and gave him a pension) S

The correct sequence should be

A) P Q R S B) P R S Q
C) Q R S P D) Q R P S
 
Answer & Explanation Answer: D) Q R P S

Explanation:

Since, the starting statement carries a subject; the next statement will carry a verb i.e. Q follows as it mentioned the discovery of the Regent. R will bethe continuing statement which states what he actually discovered. P follows next as it talked about the reaction of the Regent after the discovery. And S would be the concluding statement and thus form a coherent paragraph.

The correct formation would be, ‘The Regent having discovered that he had imprisoned an innocent man released Voltaire and gave him a pension.’
