Directions to Solve
In each question below is given a statement followed by two assumptions numbered I and II. You have to consider the statement and the following assumptions and decide which of the assumptions is implicit in the statement.
Give answer
- (A) If only assumption I is implicit
- (B) If only assumption II is implicit
- (C) If either I or II is implicit
- (D) If neither I nor II is implicit
- (E) If both I and II are implicit.
A
Neither I nor II is implicit
B
Either I or II is implicit
C
Only assumption I is implicit
D
Both I and II are implicit
E
Only assumption II is implicit
ANS:D -
Neither I nor II is implicit
Explanation:
The statement talks of 'increasing demands' of consumers. It does not imply that consumers were indifferent to price and quality earlier. So, I is not implicit. Besides, the statement mentions I that increasing competitiveness has made available to consumers a wide variety of options which has led them to comparing things and choosing the one which best suits their requirements and budget. They are thus getting better 'value for their money'. So, II is also not implicit.

A
the perpendicular to both the lines
B
the same line in the same sense
D
the same line in opposite sense
ANS:B -
the same line in opposite sense
If two forces acting at a point are in equilibrium, they must be equal in magnitude and their line of action must be along:
"the same line in opposite sense."
When two forces are in equilibrium, it means that their vector sum is zero. For this to happen, the forces must balance each other out completely. This requires that the forces have equal magnitudes but act in opposite directions along the same line.

B
only allowed to the operating system
C
entered by programs when they enter the processor
D
required to perform any I/O
ANS:D -
only allowed to the operating system
Operating in one of two possible modes, or states: the user state, or the supervisor state.
The user state is the default (normal) state of operation, in which user programs are executed. The supervisor state is a special mode of operation to which the user has no access. When it is in the supervisor state, the processor and its actions are entirely controlled by the Operating System (OS). The supervisor state is entered only on special occasions not part of the regular processing work of the CPU, like start up, shut down, dealing with hardware or software errors etc. Those special occasions are called exceptions.

ANS:A - hammer mills
Size reduction of asbestos and mica is typically done by hammer mills.
Here's why:
-
Hammer Mills:
- Hammer mills are machines that use rotating hammers or bars to impact and crush materials into smaller particles.
- They are versatile and can handle a wide range of materials, including brittle and fibrous materials like asbestos and mica.
- The hammers or bars inside the mill rotate at high speed and strike the material, breaking it apart.
-
Suitability for Asbestos and Mica:
- Asbestos: Asbestos fibers are fibrous and brittle, requiring a method that can break them into smaller, manageable sizes without excessive fiber damage.
- Mica: Mica is a mineral with layered structure and can be brittle. Hammer mills can effectively break down mica into smaller particles suitable for various applications.
-
Other Options:
- Rod Mills: Rod mills are typically used for coarser grinding and are more suitable for minerals that require finer grinding.
- Gyratory Crushers: These are used for primary crushing of large materials and are less suitable for the delicate nature of asbestos and mica.
- Crushing Rolls: Also known as roll crushers, these are used for secondary and tertiary crushing of softer materials, and may not provide the impact force needed for efficient size reduction of asbestos and mica.
Therefore, hammer mills are the preferred equipment for size reduction of asbestos and mica due to their ability to handle brittle materials and produce a uniform particle size distribution suitable for various industrial applications.
