RRB NTPC CBT 2 (Level-2) Question Paper (Held On: 13 June 2022 Shift 1) - RRB NTPC/ASM/CA/TA MCQ

Given:

SP of x items = CP of 32 items

Profit % = 28

Concept used:

SP = CP + CP × profit%

SP = selling price

CP = cost price

Calculation:

Let CP of each item be Rs. 100a

So, CP of x item = Rs. 100xa

SP of each item = 128xa

According to the question,

x.SP = 32.CP

⇒ 128ax = 3200a

⇒ x = 3200a/128a

⇒ x = 25

So, x = 25 items

∴ The value of x is 25.

Given:

sinθ + cosecθ = 1

Concept used:

cosecθ = 1/sinθ

(a - b)² = a² + b² - 2ab

Calculation:

⇒ 4sin²θ + 1 = 4sinθ

⇒ 4sin²θ + 1 - 4sinθ = 0

⇒ (2sinθ)² + 1² - 2 × 2sinθ × 1 = 0

⇒ (2sinθ - 1)² = 0

⇒ 2sinθ - 1 = 0

⇒ 2sinθ = 1

⇒ sinθ = 1/2

⇒ sinθ = sin30°

So, θ = 30°

∴ The value of θ is 30°.

The correct answer is Mass wasting.
Key Points
Mass wasting is the enormous downward movement of rock, soil, and debris caused by gravity. Mass wasting includes events like debris flows, slumps, and rock falls.

• Rocks fall:
  • Rock falls happen when chunks of rock fall down a cliff. Large bricks may eventually get loosened as a result of frost wedging, falling.
  • Talus is the term for the buildup of rock fragments at the bottom of a steep slope.
• Slump:
  • The term "slump" refers to the rotating slip of a large amount of bed rock off a high cliff. The most frequent cause of slumping is erosion at the slope's base, which lessens the support provided for underlying sediments.
• Debris avalanche:
  • The debris avalanche is the worst kind of debris flow. It flows down steep slopes in a quickly churning mass of dirt, water, rock debris, and air. By serving as a cushion between the debris and the underlying surface, the trapped air may quicken the avalanche.

Additional Information
Mass wasting also includes rockslides, landslides, mudflow, creep etc.

• Rockslides: Typically, a zone of weakness is followed by a rockslide. Slippage is exacerbated by water presence. Rockslides typically originate from collisions down the slope shattering the boulder mass into debris.
• Landslides: Large rocks that break off and roll downhill cause landslides. Both really heavy rain and earthquakes frequently start it.
• Mudflow: A mudflow is a swiftly moving liquid mass made up of soil, rock fragments, and water. They are especially frequent in semiarid highland areas.
• Creep: Creep is the gradual and slow descent of soil. Usually, its velocity is less than one centimeter each year. The gradual movement of soil particles down the hill caused by freezing and thawing contributes to soil creep.
• Hydraulic action:
  • The physical weathering and mechanical reaction of earth elements to flowing water in rivers and streams, breaking waves, and storm surge along shorelines is referred to as hydraulic action.
• Solifluction:
  • It a combination of creep and flow, creates distinct sheets, terraces, and lobes of rock and debris.
  • On steeper slopes where the process has pushed loosening boulders and dirt downslope, solifluction sheets and lobes can be seen.

Concept used:

The following steps are helpful while applying the median formula for ungrouped data.

Step 1: Arrange the data in increasing order.

Step 2: Secondly, count the total number of observations 'n'.

Step 3: Check if the number of observations 'n' is even or odd.

Median Formula When n is Odd

Median = [(n + 1)/2]^th term

Calculation:

The numbers in increasing order = 0, 0, 1, 1, 2, 3, 3, 3, 4, 4, 5, 5, 6, 7, 7

Total number of terms = 15 which is odd term

⇒ 8^th term

8^th term of the numbers is 3

∴ The median of the numbers is 3.

The correct answer is Sriman Narayan Agarwal.
Key Points
Espousing the spirit of the Gandhian economic thinking, Sriman Narayan Agarwal formulated The Gandhian Plan in 1944. The plan laid more emphasis on agriculture.

Gandhian economy:

• According to Gandhi, the salvation of the Indian economy depends on rural development and rural transformation.
• The prevailing agrarian situation indicates that this cannot be brought about in the context of India's present obsession with economic growth, and the trend of economic development in the world, in general.
• A strong rural economy lays the foundation for a strong society and nation.
• The Gandhian economy is based on the principle of Trusteeship.
• According to Gandhi, the cause of all contradictions is centralism.
• It may be described as a situation in which a few controls the means and the power to make decisions that affect many that are left out.
• Gandhian principle of economics rejects the precepts and assumptions of mainstream economics.
• It represents an alternative to mainstream economic theories as a way to promote economic progress without emphasizing material pursuits or compromising human development.

Given:

Speed of the first person = 5 km/h

Speed of the second person = 10 km/h

Train taken to overtake the first person = 21 sec

Train taken to overtake the second person = 24 sec

Concept used:

Speed = Distance/Time

km/h × 5/18 = m/sec

When two bodies move in the same direction, then Relative speed = the Difference in their speeds

Calculation:

Let the length and the speed of a train be L m/sec and V m respectively.

Speed of the first person in m/sec = 5 × 5/18 = 25/18 m/sec

Speed of the second person in m/sec = 10 × 5/18 = 25/9 m/sec

Now,

Relative speed of the train and the first person = {V – (25/18)} m/sec

So,

V – (25/18) = L/21

⇒ V = L/21 + 25/18 ----(1)

Again,

Relative speed of the train and the second person = {V – (25/9)}m/sec

So,

{V – (25/9)} = L/24

⇒ V = L/24 + 25/9 ----(2)

From eq (1) and eq (2) we can say,

L/21 + 25/18 = L/24 + 25/9

⇒ L/21 – L/24 = 25/9 – 25/18

⇒ (8L – 7L)/(168) = (50 – 25)/(18)

⇒ (L)/168 = 25/18

⇒ L = (25/18) × 168

⇒ L = m

∴ The length of the train is m.
