RRB NTPC CBT 1 Question Paper (Held On: 7 Jan 2021 Shift 1) - RRB NTPC/ASM/CA/TA MCQ

The logic followed is:
As the statements talk about the electricity board has started going from home to home to collect bills.
Assumption I is implicit because electricity board has started going from home to home to collect bills since people have to face many problems.
B. The electricity board has increased its focus on collecting bills.
From the statement, we can assume that if non - renewable sources of energy go exhausted, the next generation will not be able to use them and will have to think of alternatives as non - renewable energy will extinct if we are not saving it.
Therefore, Assumption II is implicit.
Hence, Both A and B are implicit
Additional Information

1. Read the statement with an approach that the assumptions would be true about the statement.
2. Do not go too logical with the statements. Analyze the given information and the assumption must only be made based on the information in the statement. Do not over-complicate it.
3. Common assumptions can always be followed but other than that do not align the statement with General Knowledge or other facts
4. Use the elimination method if you are unable to apprehend the answer. Read the statement and then the assumptions given in the options, you shall notice that a few of them will most definitely not follow. Eliminate them and then choosing from lesser options may prove to be more convenient
5. One thing to note is that the assumption is something that the author believes to be true, so while choosing the correct option, keep this thought in mind. If any option contradicts the statement, then that assumption will not follow.

Given:

Marks scored by one student = 65%

Marks scored by another student = 80%

Let the total marks be = y

Qualifying marks of one student = 65% of y + 20

Qualifying marks of another student = 80% of y - 10

As per the question;

65% of y + 20 = 80% of y - 10

⇒ 65/100 × y + 30 = 80/100 × y

⇒ 30 = 80y/100 - 65y/100

⇒ 15y/100 = 30

⇒ y = 200

∴ The total marks of the examination are 200.

The correct answer is 11.

Given:
P = 2 + √3, Q = 2 - √3
Formula used:
(a - b)(a + b) = a² - b²
Calculation:
By rationalization
P/Q = (2 + √3)/(2 - √3) × (2 + √3)/(2 + √3)
⇒ P/Q = (2 + √3)²/(2)²- (√3)²
⇒ P/Q = (4 + 3 + 4√3)/(4 - 3)
∴ P/Q = (7 + 4√3)/1

Given:

Principal = Rs.12000

Time = 5 years

Formulas used:

Amount = Principal × (1 + r/100)ⁿ

Calculation:

Amount = Principal × (1 + r/100)⁵

⇒ 24000 = 12000 × (1 + r/100)⁵

⇒ 24000/12000 = (1 + r/100)⁵

⇒ 2 = (1 + r/100)⁵ (1)

⇒ At the end of 15 years,

⇒ Amount = 12000 × (1 + r/100)¹⁵

⇒ Amount = 12000 × [(1 + r/100)⁵ ]³ (From 1)

⇒12000 × 2³

⇒12000 × 8

⇒ 96000

∴ The amount at the end of 15 years will be Rs.96000

Shortcut Trick

∴ The amount at the end of 15 years will be 8 times of 12000 = Rs.96000

Concept:

The standard form of a quadratic equation is ax² + bx + c = 0

Given:

One root of the equation 2x² - 8x - m = 0, is 5/2 

Calculation:

By substituting 5/2 for x in the equation 2x² - 8x - m = 0

⇒ 2 × (5/2)² - 8 × (5/2) - m = 0

⇒ 2 × 25/4 - 40/2 - m = 0

⇒ 25/2 - 40/2 - m = 0

⇒ - 15/2 - m = 0

∴ m = -15/2

Now, by putting the value of m in the equation;

⇒ 2x² - 8x - (-15/2) = 0

⇒ 2x² - 8x + 15/2 = 0

⇒ 4x² - 16x + 15 = 0

⇒ 4x² - 10x - 6x + 15 = 0

⇒ 2x(2x - 5) - 3(2x - 5) = 0

⇒ (2x - 5)(2x - 3) = 0 n

⇒ x = 5/2, 3/2

∴ The other root, x = 3/2 and m = - 15/2

Mistake Points
One root x = 5/2 is already given in the question, we only need to find the root other than 5/2, so option 3 gets eliminated.

The correct answer is Turmeric.
Key Points

• Indian government challenges the US for patenting turmeric and forces them to revoke it.
• American researchers of Indian origin, Suman K. Das and Hari Har P. Cohly of the University of Mississippi Medical Center put a claim to the US Patent and Trademark Office, maintaining that they had discovered haldi's healing properties.
• In March 1995, they received a patent for the Haldi medication.
• On March 6, 1997, the United States filed its first complaint with the World Trade Organization (WTO) against India's 'patent protection for pharmaceutical and agricultural chemical products.'
• The Council of Scientific and Industrial Research requested a reexamination from the US Patent Office.
• This came after Indian experts screamed from the rooftops about how we are losing our traditional knowledge to marauding foreign firms stealing our ancient medicinal practices.
• The US Patent Office said it made a mistake and revoked the turmeric patent.
• This is a significant victory because it rarely entirely revokes a patent that it has awarded.
• This victory will send a strong warning to all those bio-pirates of India's herbal wealth.

The pattern followed here is:

According to the alphabetical positions of the letters,
Y - 3 = V;
V - 5 = Q;
Q - 7 = J;
J - 9 = A
Hence, ‘A’ is the correct answer.

Concept:

First five composite numbers = 4, 6, 8, 9, 10 (Which are obtained by multiplying two positive integers)

First five prime numbers = 2, 3, 5, 7, 11 (Which have only 2 factors, 1 and the number itself)

Formula used:

Mean = Sum of observations/No of observations

Calculation:

Mean of first 5 composite numbers = (4 + 6 + 8 + 9 + 10)/5 = 37/5

Mean of first 5 prime numbers = (2 + 3 + 5 + 7 + 11)/5 = 28/5

∴ The required difference = 37/5 - 28/5 = 9/5

⇒ 1.8

Given:

Denominator = 2 + Numerator

Calculation:

Let the numerator be = a

⇒The denominator be = 2 + a

As per the question;

a × 3 /(2 + a) × 2 = 1/2

⇒ 3a/(2 + a) = 1

⇒ 3a = 2 + a

⇒ 2a = 2

⇒ a = 1

Numerator = 1

Denominator = 1 + 2 = 3

∴ The required fraction = 1/3

Alternate Method
By Hit & Trial Method
By checking the condition, Denominator = 2 + Numerator
Option A: 5 ≠ 2 + 2
Option B: 4 ≠ 1 + 2
Option C: 3 ≠ 2 + 1
Option D: 3 = 2 + 1

Calculation:

Let the side of original triangle be a and area is A₁ and the new area of the equilateral triangle be A₂

Area of equilateral triangle (A₁) = √3/4 × a²

According to the question

On increasing sides by three times

New area of equilateral triangle (A₂) = √3/4 × (3a)²

⇒ √3/4 × 9a²

⇒ 9 × √3/4a²

⇒ A₂ = 9A₁

∴ The area of new equilateral will become 9 times of the original area

Given:

SP = Rs. 50

Gain = 5%

Loss = 5%

Calculation:

Let the original selling price be Rs. x

According to the question

⇒ (x × 100)/105 = (x – 50) × 100/95

⇒ 19x = 21x – 1050

⇒ 2x = 1050

⇒ x = Rs. 525

∴ The original selling price is Rs. 525.00

Given:

The shadow of a pole of 10 m height = 10√3 m

Calculation:

Let the angular elevation of sun = θ

tanθ = Perpendicular/Base

⇒ tanθ = 10/10√3

⇒ tanθ = 1/√3

⇒ tanθ = tan 30°

⇒ θ = 30°

∴ The angular elevation of the sun is 30°

The pattern follows here is:
All figures except option 2 have 4 symbols - multiplication, division, square and a circle.
Option 2 have symbols - addition, division, square and a circle.
Hence, ‘option 2’ is the odd one out.

Given: 4, 14, 60, 248, ?

The logic follows here is:

4 = 4¹ - 0

14 = 4² - 2 = 4² - 2¹

60 = 4³ - 4 = 4³ - 2²

248 = 4⁴ - 8 = 4⁴ - 2³

So the series is of the form

4ⁿ - 2^n-1 where n = 1, 2, 3, 4, .....

So the next term is obtained by putting n = 5

Similarly,

= 4⁵ - 2⁴

= 1024 - 16

= 1008

Hence, 1008 is the correct answer.

Calculation:

Percentage increase in sales of mobile phones in 2004 = 35

Percentage increase in sales of mobile phones in 2008 = 70

Percentage increase in sales of mobile phones from 2004 to 2008 = (70 – 35)/35 × 100

⇒ 35/35 × 100

⇒ 100%

∴ The required percentage is 100%

The logic is:

As PAINT is coded as 83527 and SCORE is coded as 49061.
