RRB NTPC CBT 2 (Level-2) Question Paper (Held On: 16 June 2022 Shift 1) - Question 1

Water has the highest density at nearly ______ Kelvin.

Detailed Solution for RRB NTPC CBT 2 (Level-2) Question Paper (Held On: 16 June 2022 Shift 1) - Question 1

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%.
RRB NTPC CBT 2 (Level-2) Question Paper (Held On: 16 June 2022 Shift 1) - Question 2

A field is in the shape of a rhombus whose side is 122 m. The length of one of its diagonals is 240 m. What is the area (in m2) of the field?

Detailed Solution for RRB NTPC CBT 2 (Level-2) Question Paper (Held On: 16 June 2022 Shift 1) - Question 2

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.

I. The second number is two times the first number.
II. All the five even numbers are consecutive even numbers in increasing order.

Detailed Solution for RRB NTPC CBT 2 (Level-2) Question Paper (Held On: 16 June 2022 Shift 1) - Question 3

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

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.

Arvind bought 120 m cloth for Rs. 15000. He sold 45% of it at a gain of 40%, 25% of it at a loss of 10% and the remaining cloth at the cost price. His profit (in Rs.) in the entire transaction is
Detailed Solution for RRB NTPC CBT 2 (Level-2) Question Paper (Held On: 16 June 2022 Shift 1) - Question 18

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

  • 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.

In each of the number-pairs, the second number is obtained by performing a certain mathematical operation on the first number. Three of the following pairs follow the same pattern and thus form a group. Select the number-pair that does NOT belong to that group.

Detailed Solution for RRB NTPC CBT 2 (Level-2) Question Paper (Held On: 16 June 2022 Shift 1) - Question 23

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.

Let x be the median of the data: 16, 78, 26, 91, 29, 71, 31, 46, 9, 51, 54, 56, 61, 21, 62, 65, 73, 86, 41, 89. Let y be the median of the data obtained when 26 and 41 are replaced by 59 and 75, respectively, in the above data. What is the value of (3x - 2y)?

Detailed Solution for RRB NTPC CBT 2 (Level-2) Question Paper (Held On: 16 June 2022 Shift 1) - Question 26

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)/2th 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 = 20/2th + (20/2 + 1)/2th = 10th & 11th 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 = 20/2th & (20/2 + 1)th = 10th & 11th 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.

RRB NTPC CBT 2 (Level-2) Question Paper (Held On: 16 June 2022 Shift 1) - Question 28
The L.C.M. of two numbers is 252 and their H.C.F. is 14. If one of the numbers is 28, then by what percentage is the other number more than 28?
Detailed Solution for RRB NTPC CBT 2 (Level-2) Question Paper (Held On: 16 June 2022 Shift 1) - Question 28

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.

Detailed Solution for RRB NTPC CBT 2 (Level-2) Question Paper (Held On: 16 June 2022 Shift 1) - Question 29

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.
