The second plan was conceived in an atmosphere of economic stability.
It was felt agriculture could be accorded lower priority.
Industries got more importance in the 2nd five-year plan. The focus was mainly on heavy industries.
The Indian government boosted the manufacturing of industrial goods in the country.
This was done primarily to develop the public sector.
The Plan Focussed on rapid industrialization- heavy & basic industries.
Advocated huge imports through foreign loans.
Therefore, the Indian Government adopted a mixed economy during the second five-year plan. Hence, Option 2 is correct.
The Industrial Policy 1956 was based on the establishment of a socialistic pattern of society as the goal of economic policy.
Acute shortage of forex led to pruning of development targets, the price rise was also seen ( about 30%) vis a vis decline in the earlier Plan & the 2nd FYP was only moderately successful.

Important Points

The 2nd year five-year plan functioned based on the Mahalanobis model.
The Mahalanobis model was propounded by the famous Prasanta Chandra Mahalanobis in the year 1953.
As many as five steel plants including the ones in Durgapur, Rourkela ,Bhilai were set up as per the 2nd five-year plan.

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

When 5 men can build a wall in 12 days, to build a wall 50% more than the original wall in 10 days, the number of men required is:
Detailed Solution for RRB NTPC CBT 1 Question Paper (Held On: 7 Jan 2021 Shift 1) - Question 7

Given:

Time taken by 5 men to build a wall = 12 days

Formula used:

(M1 × D1)/W1 = (M2 × D2)/ W2

Calculation:

Let the work size of the wall = 100

⇒ The size of the wall 50% more than the original wall = 100 × 150/100 = 150

Let the men required to build the 50% more than the original wall = a

(5 × 12)/100 = (a × 10)/150

⇒ 60/100 = 10a/150

⇒ 3/5 = a/15

⇒ 3/1 = a/3

⇒ a = 9

∴ The required no of men = 9

When a number n is divided by 5, the remainder is 2. When n2 is divided by 5, the remainder will be:

Detailed Solution for RRB NTPC CBT 1 Question Paper (Held On: 7 Jan 2021 Shift 1) - Question 10

Concept:
Dividend = Divisor × Quotient + Remainder
Calculation:
Let the quotient be = b
n = 5 × b + 2
n2 = (5b + 2)2
⇒ n2 = 25b2 + 4 + 2 × 5b × 2
⇒ n2 = 25b2 + 4 + 20b
⇒ n2 = 5(5b2 + 4b) + 4
∴ When n2 is divided by 5, the remainder will be 4.
Alternate Method
By Value Putting Method
n/5 → Remainder = 2
For n = 7, it satisfies the condition.
⇒ n2/5 = 72/5 = 49/5
∴ The remainder (5 × 9 + 4) = 4

In a school, the number of boys and girls were in the ratio 5 : 7. Eight more boys were admitted during the session. The new ratio of girls and boys is 1 : 1. In the beginning, the difference between the number of boys and that of girls was:
Detailed Solution for RRB NTPC CBT 1 Question Paper (Held On: 7 Jan 2021 Shift 1) - Question 15

Given:

Ratio of number of boys and girls = 5 : 7

New ratio of the number of boys and girls = 1 : 1

Calculation:

Let the number of boys and girls be 5a and 7a respectively.

After admission of 8 more boys;

(5a + 8)/7a = 1/1

⇒ 5a + 8 = 7a

⇒ 7a - 5a = 8

⇒ 2a = 8

⇒ a = 4

∴ The difference between the number of boys and girls in the beginning = 7a - 5a = 2a

⇒ 2 × 4 = 8

Shortcut Trick When 8 more boys were admitted the ratio 5 : 7 became 1 : 1.

⇒ Number of girls remained unchanged, that is 7 in the beginning.

So, after admission of 8 boys the number of boys and girls became equal.

⇒ 7 - 5 = 2 = 8 boys

Also, the difference in the number of boys and girls is also (7 - 5) = 2

∴ 2 = 8

⇒ b2 + 4 + 4b - b2 = 56

⇒ 4b = 56 - 4

⇒ 4b = 52

Detailed Solution for RRB NTPC CBT 1 Question Paper (Held On: 7 Jan 2021 Shift 1) - Question 20

Given:

Devesh leaves his home 7 AM and reaches office at 8:30 AM

One day 1/5 of the distance covered at 5/6th of his usual speed

And rest of the distance covered at 6/5 of his usual speed.

Formula used:

Time = Distance/Speed

Calculation:

Let the distance covered by Devesh be = d

Let the time be = t

Let the speed be = s

From 7 AM to 8:30 Am = Time = 1.5 hours

As per the question;

(d/5)/(5s/6) + (4d/5)/(6s/5)

⇒ d/5 × 6/5s + 4d/5 × 5/6s

⇒ 6d/25s + 2d/3s

⇒ (6/25 + 2/3) × d/s

⇒ (18 + 50)/75 × t

⇒ 68/75 × 1.5 hours

⇒ 68/75 × 3/2

⇒ 34/25

⇒ 1 hour and 9/25 × 60 minutes

⇒ 1 hour and 21.6 minutes

∴ Approximately, Devesh reach at office at 8:21 Am on that day.

For which Indian spice did the Indian government challenge the US patenting and force them to revoke it?

Detailed Solution for RRB NTPC CBT 1 Question Paper (Held On: 7 Jan 2021 Shift 1) - Question 22

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 Pie Chart represents the share of savings and expenses under different heads, from the monthly salary of Manish.

If Manish’s salary is Rs. 50,000 and he wishes to double his monthly savings and spend 50% of the balance amount on his Household expenses, by what amount would he need to reduce on the other expenses.

Detailed Solution for RRB NTPC CBT 1 Question Paper (Held On: 7 Jan 2021 Shift 1) - Question 25

Given:

Monthly salary of Manish = Rs.50000

Old savings = 10% × 50000 = 5000

Calculation:

Old expenses on household = 40/100 × 50000 = Rs.20000

Old amount on other expenses = Salary - (Old savings + Old household expenses)

⇒ Rs.50000 - (Rs.20000 + Rs.5000) = Rs.25000

As per the question;

New savings = 2 × 10/100 × 50000 = Rs.10000

New balance of the salary = 50000 - 10000 = Rs.40000

Amount to be used on Household expenses = 50% of Rs.40000

⇒ 50/100 × 40000 = Rs.20000

New amount of other expenses = Salary - (New savings + New household expenses)

⇒ Rs.50000 - (Rs.10000 + Rs.20000) = Rs.20000

∴ Reduction on the other expenses = Old - New

⇒ Rs.25000 - Rs.20000 = Rs.5000

Select the number from among the given options that can replace the question mark (?) in the following series.

4, 14, 60, 248, ?

Detailed Solution for RRB NTPC CBT 1 Question Paper (Held On: 7 Jan 2021 Shift 1) - Question 28

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

So the next term is obtained by putting n = 5

Similarly,

= 45 - 24

= 1024 - 16
