RRB NTPC CBT 2 (Level-2) Question Paper (Held On: 16 June 2022 Shift 1) - RRB NTPC/ASM/CA/TA MCQ

The correct answer is 277.
Key Points
Water Density :

• The density of water is measured as weight per unit volume of the water and it is mainly dependent on the temperature of water.
• In the crystal lattice, there are lot of void area present, when the water is in its ice form doe to sufficient hydrogen bonding between the water molecules. This crystal structure begins to collapse as the ice begin to melt.
• As the temperature increases, the molecules of water start migrating farther from each other hydrogen bond start collapsing and therefore the molecules start coming close to each other resulting in the increase of water density and decrease in volume.
• At 273 kelvin (0°C), ice clusters are seen in the water which are allowed to move freely. Due to the vacant spaces present in the ice clusters, its density get reduced and volume is increased.
• At 0 and 227 kelvin the temperature decreases and thus the density decreases.
• At 277 kelvin (4°C), as the temperature increases the clusters begin to deform, resulting in the highest water density.

Additional Information

• The unit of temperature kelvin is converted into celcius (C) by
  • K = C + 273, thus 277 kelvin is 4°C ( K = 4 + 273 = 277 kelvin)
• After 277 k, the rise in volume due to the expansion of liquid water becomes more than the reduce in volume caused due to hydrogen bond breakage.
• After 277 k, there is a net gain in volume during heating, which leads to a decrease in density.
• It falls within a variety of abnormal physical properties.
• As compared to liquid water, the density of ice is less and thus ice floats on water.
• When we freeze the water, the density of ice is reduced by about 9%.

Given:

Side of the rhombus = 122 m

Length of one of the diagonal, (D₁) = 240 m

Formula used:

Area of rhombus = 1/2 × Diagonal₁ × Diagonal₂

Concept used:

Diagonal of a rhombus bisect each other at 90°.

Pythagoras Theorem = (Hypotenuse)² = (Perpendicular)² + (Base)²

Calculation:

According to the question,

Let the length of the other diagonal be 2x meter.

In triangle AOB,

⇒ (AO)² + (OB)² = (AB)²

⇒ x² + (120)² = (122)²

⇒ x² = 14884 - 14400

⇒ x² = 484 = 22m

Length of diagonal 2, D₂ = 2x = 44m

Now Area of the rhombus

⇒ Area = 1/2 × 240 × 44

⇒ Area = 1/2 × 10560 = 5280 m²

∴ The area (in m2) of the field is 5280 m².

​We have to find total of five natural even numbers .
Explanation:
Statement I: The second number s two times the first number.

• Let the first number = x
• Then, the second number = 2x

Statement II: All the five even numbers are consecutive even numbers in increasing order.

• We get that number will be x, x + 2, x + 4, x + 6, x + 8.
• Combining I and II, we get
• x + 2 = 2x
• x = 2

Total of five natural even numbers = x + x + 2 + x + 4 + x + 6 + x + 8 = 2 + 4 + 6 + 8 + 10 =30
Hence, Both the Statements together are necessary to answer the Question is the correct answer.

Given: Q ≤ R = S > T < U ≥ V

Explanation:

• V < T →(False) T< U ≥ V → (As U > T and U ≥ V then T > V is does not follow)
• S < Q→(False) Q ≤ R = S → (As Q ≤ R and R = S. So, Q > S is does not follow)

Hence, Neither I nor II is true is the correct answer.

Eight friends: K, L, M, N, O, P, Q and R

• Number of friends = 8, namely, K, L, M, N, O, P, Q, R
• K, L, M and N are sitting in a straight line and are facing North.
• O, P, Q and R are sitting on a parallel line and are facing South.
• ​Each of the persons sitting in a line, faces another person sitting in the parallel line.
• M faces a person who has two people sitting to his right. M is facing North.​

​

• N is sitting between M and K.

• Q faces K.

​

• O is neither an immediate neighbour of P nor Q.

Hence, R is the correct answer.

Given:

A can do the piece of work in 8 days,

B can do the piece of work in 10 days

C can do the piece of work in 20 days

Calculations:

According to the question,

One day work of A = 1 / 8 .........(1)

One day work of B = 1 / 10 .........(2)

One day work of C = 1 / 20 .........(3)

Adding all the equations (1), (2), and (3)

⇒ A + B + C = (1 / 8) + (1 / 10) + (1 / 20)

⇒ A + B + C = (5 + 4 + 2) / 40

⇒ A + B + C = 11 / 40

∴ A, B, and C together do the same work in 40/11 days or days.

Hence, the required answer is

The logic followed here is:

Manufacturing and Health sectors drove growth during the second lockdown (Cause) and as the demand grew rapidly, India's economy sees record growth during the deadly Covid second wave (Effect)

Hence Statement II is the cause and statement I is its effect.

Additional Information

What are Causes?

Causes are the conditions under which an event occurs.

For example, can you guess the causes for the following?

The police increased security around the President's house.

Lots of people buy a particularly expensive brand of washing machines around Diwali. Easily, we can guess the causes for the above events.

There were reports of threats against the President.

There was a high discount or sale for that brand during Diwali.

Sufficient & Necessary Conditions:

In a cause and effect question, the cause is the sufficient condition. It is assumed that the sufficient condition of the occurrence of the events must include the different necessary conditions as well.

A necessary condition is one that must be satisfied for the occurrence of an event.

E.g. You must adhere to the deadline to get your work appraised.

This means if you get your work appraised, you have to adhere to the deadline. Or; if you do not adhere to the deadline, you do not get your work appraised.

A condition is called a sufficient condition if in a certain event, you are satisfied with the results.

E.g. Being human is a sufficient condition for being a mammal. Being a human is not possible unless one is also a mammal. But it is not necessary that being human is a necessary condition for being a mammal.

Given:

CP of 120 m cloth = Rs. 15000

Gain% on 45% of cloth = 40%

Loss% on 25% of cloth = 10%

Formula used:

⇒ SP = CP + Profit

⇒ SP = CP - Loss

Calculations:

According to the question,

CP of 120 m cloth = Rs. 15000

⇒ CP of 1 m cloth = 15000/120 = Rs. 125/m

Now for SP of 45% of cloth,

45% of 120 m cloth = (45 × 120)/100

⇒ 5400/100 = 54 m

CP of 54 m cloth = 54 × 125 = Rs. 6750

⇒ SP = CP + 40% of CP

⇒ SP = 6750 + 40% × 6750

⇒ SP = 6750 + 2700 = Rs. 9450

SP of 45% of cloth is Rs. 9450

Now for SP of 25% of cloth,

⇒ 25% of 120 m cloth = (25 × 120)/100

⇒ 3000/100 = 30 m

⇒ CP of 30m cloth = 30 × 125 = Rs. 3750

⇒ SP = CP - 10% of CP

⇒ SP = 3750 - 10% × 3750

⇒ SP = 3750 - 375 = Rs. 3375

SP of 25% of cloth is Rs. 3375

Now for SP of the rest of the cloth,

Remaining cloth = 45% + 25% + x% = 100%

⇒ Remaining cloth = 30%

⇒ 30% of 120 m cloth = (30 × 120)/100

⇒ 3600/100 = 36 m

⇒ CP of 36m cloth = 36 × 125 = Rs. 4500

⇒ SP = CP

SP of rest of the cloth is Rs. 4500

Now to find the total profit,

[(SP of 45% of the cloth) + (SP of 25 of the cloth) + (SP of rest of the cloth)] - [CP of the whole cloth]

⇒ [(9450) + (3375) + (4500)] - [15000]

⇒ Total Profit = 17325 - 15000 = Rs.2325

∴ His profit (in Rs.) in the entire transaction is Rs. 2325

Given:

(44.97% of 226) + 55.03 × 4.98 - ? = 140

Calculations:

Let unknown no. be 'x'.

(0.45 × 226) + 55 × 5 - (x) = 140

⇒ (102) + 275 - 140 = x

⇒ x = 377 - 140 = 237.

∴ The simplified value is 237.

The correct answer is Ginning.

Key Points

• The process of separating cotton fibres from seeds is called ginning.
• From the field, seed cotton moves to nearby gins for separation of lint and seed.
• The cotton first goes through dryers to reduce moisture content and then through cleaning equipment to remove foreign matter.
• These operations facilitate processing and improve fiber quality.
• The cotton is then air conveyed to Cotton Ginning in stands where revolving circular saws pull the lint through closely spaced ribs that prevent the seed from passing through.
• The lint is removed from the saw teeth by air blasts or rotating brushes, and then compressed into bales weighing approximately 500 pounds.
• Cotton is then moved to a warehouse for storage until it is shipped to a textile mill for use.
• A typical gin will process about 12 bales per hour, while some of today’s more modern gins may process as many as 60 bales an hour.

Additional Information

• Yarning is the process where the cotton yarn is spinned at the initial stage of textile processing.
• Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product.
• Molding is the process where specific thing is moulded into the desired shape.

• Sangeet Ratnakar was called the "Ocean of Music and Dance", is one of the most important musicological texts from India.
• The text is divided into seven chapters
• The first six chapters Svaragatadhyaya, Ragavivekadhyaya, Prakirnakadhyaya, Prabandhadhyaya, Taladhyaya and Vadyadhyaya.
• Sarnga Deva, was the 13th-century Musician who authored Sangeet Ratnakar – the classical Sanskrit text on music and drama.

Additional Information

• Amir Khusrau is called the father of qawwali and was the one who introduced ghazal in India.
• Tansen is also known to as Tan Sen or Ramtanu, was a well known person of North Indian classical music.
• Muhammad Shah was a great patron of the arts, including musical, cultural and administrative developments.

The correct answer is Cache Memory.

Key Points

• Cache memory is a chip-based computer component that makes retrieving data from the computer's memory more efficient.
• ​Cache, which is pronounced "cash" (not "catch" or "cashay"), stores recently used information so that it can be quickly accessed at a later time.
• Computers incorporate several different types of caching in order to run more efficiently, thereby improving performance.
• Common types of caches include browser cache, disk cache, memory cache and processor cache.

Additional Information

• Tertiary memory is a level below secondary storage
  • Typically, it involves a robotic mechanism which will mount (insert) and dismount removable mass storage media into a storage device according to the system's demands; such data are often copied to secondary storage before use.
• Optical memory
  • Optical memory is an electronic storage medium that uses a laser beam to store and retrieve the data. If we classify the memory system then optical memory comes under the external memory in the computer system.
• Auxiliary memory
  • Auxiliary memory units are among computer peripheral equipment.
  • They trade slower access rates for greater storage capacity and data stability.
  • Auxiliary memory holds programs and data for future use, and, because it is nonvolatile (like ROM).
  • It is used to store inactive programs and to archive data.

The logic followed here is:
Logic: First number × First number + First number = Second number
A. 3 : 12 → 3 × 3 + 3 = 12
B. 14 ∶ 220 → 14 × 14 + 14 = 210 ≠ 220
C. 11 ∶ 132 → 11 × 11 + 11 = 132
D. 5 ∶ 30 → 5 × 5 + 5 = 30
Hence, '14 ∶ 220' is the odd one out.

The correct answer is the Second Five-Year Plan.

• The Second Five-Year Plan pointed out that 'the benefits of economic development must accrue more and more to the relatively less privileged classes of society'.

• The Twelfth Plan completed its term in March 2017.
• With the Planning Commission dissolved, no more formal plans are made for the economy, but Five-Year Defence Plans continue to be made.
• The latest would have been 2017–2022. However, there is no Thirteenth Five-Year Plan.

The correct answer is Parliament.
Key Points

• The Fifth Amendment of the Constitution of India, officially known as The Constitution Act, 1955.
• It empowered the President to prescribe a time limit for a State Legislature to convey its views on proposed Central laws relating to the formation of new States and alteration of areas, boundaries or names of existing States.
• The amendment also permitted the President to extend the prescribed limit, and prohibited any such bill from being introduced in Parliament until after the expiry of the prescribed or extended period.
• Parliament can form a new state by separating the territory from any state, by merging two or more states or parts of states.
• Parliament can also reduce or increase the area or alter the boundary of any state or even change its name.
• But first, a bill on the matter has to be referred by the President to the legislature of the affected state so that the legislature can express its views within a certain period.

Given:

The data: 16, 78, 26, 91, 29, 71, 31, 46, 9, 51, 54, 56, 61, 21, 62, 65, 73, 86, 41, 89

Formula Used:

Median for even no. of observations = Average of (n/2)^th & (n/2 + 1)/2^th term

Calculations:

Let the Median of original data be 'x'

Arranging the data in ascending order,

9, 16, 21, 26, 29, 31, 41, 46, 51, 54, 56, 61, 62, 65, 71, 73, 78, 86, 89, 91

⇒ Total no. of observations = 20

⇒ Median = 20/2^th + (20/2 + 1)/2^th = 10^th & 11^th term

⇒ Median = (54 + 56)/2 = 55

Now observations 26 and 41 are replaced by 59 and 75 the new data will be,

Let the New Median be 'y',

9, 16, 21, 29, 31, 46, 51, 54, 56, 59, 61, 62, 65, 71, 73, 75, 78, 86, 89, 91

⇒ Total no. of observations = 20

⇒ New Median = 20/2^th & (20/2 + 1)^th = 10^th & 11^th term

⇒ New Median = (59 + 61)/2 = 60

According to the question,

(3x - 2y) = (3 × 55) - (2 × 60)

⇒ 165 - 120 = 45

∴ The value of (3x - 2y) is 45

Additional Information

⇒ Median for odd no. of observations = [(n + 1)/2]^th term.

Given:

LCM = 252

HCF = 14

One Number = 28

Formula used:

Percentage = Required Value/Total Value × 100

Concept used:

LCM × HCF = Product of the two numbers

Calculations:

Let the other no. be 'a'

⇒ 252 × 14 = 28 × a

⇒ a = (252 × 14)/28

⇒ a = 3528/28 = 126

Required % = (126 - 28)/28 × 100 = (98 × 100)/28 = 350%

∴ 350% percentage is the other number more than 28.

Given:

A can complete a piece of work alone in 20 days,

B can do it alone in 15 days,

C can complete it alone in 18 days

B and C started the work together but both were forced to leave after 4 days

Calculations:

According to the question,

⇒ Work done by A in 1 day = 1/20

⇒ Work done by B in 1 day = 1/15

⇒ Work done by C in 1 day = 1/18

⇒ Work done by B and C in 1 day = 1/15 + 1/18 = (6 + 5)/90 = 11/90

⇒ Work done by B and C in 4 days = 4 × 11/90 = 22/45

Assuming the total work in the job as a whole = 1

The remaining work = Total work - Work done by B and C in 4 days = 1 - 22/45 = 23/45

Time taken to complete the work,

⇒ (23/45)/ (1/20)

⇒ (23/45) × 20 = 92/9 days =

∴ The remaining work was done by A in days.
