Detailed Solution for Delhi Police Constable Mock Test - 4 - Question 13

1. Are over hot spots in the crust:
- Geothermal energy is generated by harnessing the heat from the Earth's crust, particularly in areas where there are hot spots.
- These hot spots are locations where molten magma is close to the surface, causing the surrounding rocks to heat up.
2. Have a high geothermal gradient:
- The geothermal gradient refers to the rate at which the temperature increases with depth in the Earth's crust.
- Regions with a high geothermal gradient are more suitable for geothermal energy production as they indicate a significant amount of heat available.
3. Have suitable geological conditions:
- The presence of permeable rocks or fractures in the Earth's crust is essential for the extraction of geothermal energy.
- These geological conditions allow for the circulation of water or other fluids through the hot rocks, which can be used to generate electricity or provide heating.
4. Are relatively close to the Earth's surface:
- Geothermal energy is easier to extract in regions where the hot rocks are closer to the surface.
- In such areas, drilling deep wells is not required, making the extraction process more cost-effective.
5. Have appropriate water resources:
- Geothermal power plants require a significant amount of water for the extraction and conversion of geothermal energy.
- Therefore, regions with ample water resources, such as underground reservoirs or nearby lakes and rivers, are beneficial for geothermal energy production.
6. Have supportive government policies:
- The feasibility of geothermal energy also depends on the presence of supportive government policies and regulations.
- Governments that incentivize and promote the development of geothermal energy can make it more financially viable and attractive for investors.

  1. Complete state monopoly of the industrial sector

  2. Promotion of regional equality

  3. Surplus industrial production

Select the correct answer using the code given below.

Detailed Solution for Delhi Police Constable Mock Test - 4 - Question 24
  • Industrial Policy Resolution 1956 (IPR 1956): In accordance with the goal of the state controlling the commanding heights of the economy, the Industrial Policy Resolution of 1956 was adopted. This resolution formed the basis of the Second Five Year Plan, the plan which tried to build the basis for a socialist pattern of society.

  • This resolution classified industries into three categories:

    • The first category comprised industries which would be exclusively owned by the state

    • the second category consisted of industries in which the private sector could supplement the efforts of the state sector, with the state taking the sole responsibility for starting new units

    • the third category consisted of the remaining industries which were to be in the private sector. Hence option 1 is not correct.

  • Although there was a category of industries left to the private sector, the sector was kept under state control through a system of licenses. No new industry was allowed unless a license was obtained from the government. This policy was used for promoting industry in backward regions; it was easier to obtain a license if the industrial unit was established in an economically backward area. In addition, such units were given certain concessions such as tax benefits and electricity at a lower tariff. The purpose of this policy was to promote regional equality. Hence option 2 is correct.

  • Even an existing industry had to obtain a license for expanding output or for diversifying production (producing a new variety of goods). This was meant to ensure that the number of goods produced was not more than what the economy required. A license to expand production was given only if the government was convinced that the economy required a larger quantity of goods. Hence option 3 is not correct.

Detailed Solution for Delhi Police Constable Mock Test - 4 - Question 25
  • Headline inflation is the total inflation in an economy. The headline inflation figure includes inflation in a basket of goods that includes commodities like food and energy. Hence statement 1 is correct.

  • Core inflation excludes food and fuel items from headline inflation. Since the prices of fuel and food items tend to fluctuate and create ‘noise’ in inflation computation, core inflation is less volatile than headline inflation. Hence statement 2 is not correct.

Delhi Police Constable Mock Test - 4 - Question 76

Two students appeared for an examination. One of them secured 22 marks more than the other and his marks were 55% of the sum of their marks. The marks obtained by them are _______.

Detailed Solution for Delhi Police Constable Mock Test - 4 - Question 76

Given:

Two students appeared for an examination. One of them secured 22

marks more than the other and his marks were 55% of the sum of

their marks

Calculation:

Let the students be A and B

Let the marks secured by B = x

Marks secured by A = x + 22

Sum of their marks of A & B = x + x + 22 = 2x + 22

Accoring to question, 

Marks of A =  55% of the sum of marks

⇒  x + 22 = 0.55 × (2x + 22) 

⇒ x + 22 = 1.1x + 12.1

⇒ 0.1x = 9.9

⇒ x = 9.9/0.1 = 99 marks

Marks secured by A = 99 + 22 = 121 marks

Therefore the correct answer is 121.
Shortcut Trick:

Let us go by options.

The difference between the numbers is 22 in all cases.

So, now check the next statement.

121 = 0.55 × (121+ 99) 

That is, as the first option itself satisfies the condition and since we do no have a combination of answers, it is the solution.

∴ The required numbers are 121 and 99.

Delhi Police Constable Mock Test - 4 - Question 89

A and B together can complete a work in 3 days. They start together but after 2 days, B left the work. If the work is completed after two more days, B alone could do the work in

1/3 part of work is completed by A in two days
Hence, one day's work of A = 1/6
Then, one day's work of B = 1/3−1/6 = 1/6
So, B alone can complete the whole work in 6 days.
