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.

Calculations :

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

The correct answer is marginal revenue has a positive value; marginal revenue has a negative value.

Key Points

• The demand curve is a concept in economics that plots the price of a product or service against how much of the product or service people buy.
• Typically, the lower the price of an item, the more people buy.
• However, that relationship varies depending on the item.
• An elastic demand curve means that a change in price has a large effect on buying, while an inelastic demand curve means that a price change has less effect on buying.

Additional Information

• Marginal revenue is related to the price elasticity of demand — the responsiveness of quantity demanded to a change in price.
• When marginal revenue is positive, demand is elastic; and when marginal revenue is negative, demand is inelastic.
• On a graph with both a demand curve and a marginal revenue curve, demand will be elastic at all quantities where marginal revenue is positive.
• Demand is unit elastic at the quantity where marginal revenue is zero.
• If the elasticity of demand is less than zero then it denotes that the change in quantity demand is opposite to the change in its own price.
• It means that the slope of the demand curve is negative at this point and the marginal revenue is also negative due to negative slope.

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

Altitude of triangle = 12 cm

Concept

Altitude of an equilateral triangle is a median of an equilateral triangle.

Length of altitude of equilateral triangle = √3/2 × side of the triangle

Calculation

Let the side of an equilateral triangle is x cm.

12 = √3/2 × x

⇒ 24/√3 cm

Perimeter of triangle = 3(side)

⇒ 3 × (24/√3)

⇒ 24√3 cm.

Alternate Method
Given:

Height of the equilateral triangle = 12 cm

Formula used:

The perimeter (P) of a triangle is = Sum of all the sides

Concept used:

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

⇒ sin 60° = √3/2

Calculations:

Considering the height of the triangle as perpendicular then,

⇒ sinθ = (Perpendicular)/(Hypotenuse)

⇒ sin 60° = 12/H

⇒ H = (12 × 2)/√3 = 24/√3

Now the perimeter of the triangle,

⇒ P = 3 × Side

⇒ P = 3 × 24/√3 = 24√ 3

∴ The perimeter of the triangle is 24√3.

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.
