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:

Liquids and gases never show

A) diamagnetic property B) paramagnetic property
C) ferromagnetic property D) electromagnetic property
 
Answer & Explanation Answer: C) ferromagnetic property

Explanation:

On the basis of magnetic properties, substances are classified into three groups namely diamagnetic, paramagnetic and ferromagnetic.

As solids diffuse and reorder very slowly under ambient conditions, the net, directionally dependent (anisotropic) magnetic moment can persist. Conversely, liquids and gases freely tumble and reorder: water rearranges every few pico seconds (10^12 times per second).

Hence liquids and gases can never show ferromagnetic properties.

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.’
