Total Questions: 50

31. Which of the following statements are correct?

1. Kolkata port is the only riverine major port of India.

2. The port of Cochin is located on the Willington Island

3. Maharashtra has three major ports

4. Mundra port is India's major port in private sector

Select the correct answer using the code given below :

Correct Answer: (d) 1, 2 and 4
Solution:Kolkata Snave Port is the only riverine major port in India. It is officially known as Syama Prasad Mookerjee Port Trust. It spreads around 203 kilometres (126 mi) from the sea. The port of Kochin is located on Wellington Island.

It is also the first transhipment terminal in India. The port lies on two islands in the Lake of Kochi. Mundra port is India's major port in the private sector. The "Vindhyan Supergroup" is one of the largest and thickest sedimentary successions in the world. Therefore, the correct option is (d).

32. Perth located on 118° East Longitude will be celebrating New Year event on 1st of January 2017 at 6:00 AM. At that time, what would be the time at Los Angeles located on 110° West Longitude?

Correct Answer: (b) 2:48 PM of 31st December 2016
Solution:It is given that one hour of time difference corresponds to 15° of longitude.

The difference in the longitude of Perth and Los Angeles = 110°-(-118°) = 228°

Difference = 228°, i.e., 15 hours 12 minutes

We know that the longitude of Los Angeles is lesser than Perth, so the time at Los Angeles would be before 15 hours 12 minutes than Perth.

Hence, at the given time, Los Angeles had 2:48 PM of 31st December 2016. Therefore, the correct option is (b).

33. Which one of the following states has the maximum number of registered E-Waste recyclers / dismantlers?

Correct Answer: (c) Karnataka
Solution:The maximum number of registered E-Waste recyclers/dismantlers are present in the state of Maharashtra. There are 75 registered E-Waste recyclers/dismantlers with 78179 MTA capacity in the state.

There are 71 registered E-Waste recyclers/dismantlers with 52722 МТА capacity present in the state of Karnataka. There are 41 registered E-Waste recyclers/dismantlers with 243627 MTA capacity present in the state of Uttar Pradesh. Therefore, the correct option is (c).

34. Arrange the following substances in their order of increasing hardness:

1. Gypsum

2. Topaz

3. Fluorite

4. Feldspar

Select the correct answer using the code given below :

Correct Answer: (b) 1-3-4-2
Solution:Hardness is defined as a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion. Carl Friedrich Christian Mohs was a German geologist and mineralogist. He was the creator of the Mohs scale of mineral hardness.

The increasing order of the harness substances are as follows: talc <gypsum <calcite <fluorite < apatite < orthoclase < feldspar < quartz < topaz< corundum < diamond Hence, the order will be: 1-3-4-2.

Therefore, the correct option is (b).

35. During 2014-2015, in which one of the following industrial sectors, the FDI equity inflow was maximum?

Correct Answer: (b) Services (Financial, Banking and Insurance, Non-Financial / Business, R & D etc.)
Solution:The government is taking steps to improve ease of doing business and attracting investments, FDI inflows into the services sector grew by over 46 per cent to USD 3.25 billion in 2014-15. A foreign direct investment (FDI) is defined as an investment made by a firm or individual in one country into business interests located in another country.

Generally, when an investor establishes foreign business operations or acquires foreign business assets in a foreign company, a foreign investment takes place. Therefore, the correct option is (b).

36. Which one of the following is not an industrial corridor as per the policy initiatives?

Correct Answer: (c) Kolkata - Guwahati
Solution:Kolkata - Guwahati is not an industrial corridor as per the policy initiatives.Industrial Corridors are defined as stretches allocated to a specific geographical area in a country with the intent to stimulate industrial development.

There are five industrial corridors, Delhi-Mumbai Industrial Corridor (DMIC), Chennai-Bengaluru Industrial Corridor (CBIC), Bengaluru-Mumbai Economic Corridor (BMEC), Amritsar-Kolkata Industrial Corridor (AKIC) and East Coast Economic Corridor (ECEC).

The corridors include High-speed transportation networks, modern airports, Special economic regions, Knowledge, infrastructure such as townships/real estate, etc. Therefore, the correct option is (b).

37. Which one of the following statements is not correct?

Correct Answer: (b) Bleaching powder acts as a reducing agent in many chemical industries
Solution:Bleaching powder is calcium hypochlorite. It has a chemical formula, CaOCl₂. It releases chlorine gas when reacts with dilute acids. It is which is a strong oxidizing agent. Chlorine is the main element of bleaching powder.

In the textile industry, it is used for bleaching dirty clothes in the laundry, as a bleaching agent for cotton and linen. It is a bleaching agent and is used for disinfecting water. Therefore, the correct option is (b).

38. Which one of the following statements is not correct?

Correct Answer: (d) Graphite has a tetrahedral structure
Solution:Graphite is a non-metal. It is an allotrope of carbon. It is also a good conductor of electricity. The carbon atoms are joined together and arranged in layers. It has strong links between the carbon atoms and weak links between the layers are weak.

The layered structure consists of rings of six carbon atoms arranged in a widely spaced horizontal sheet. There are no covalent bonds between the layers. Therefore, the correct option is (d).

39. Consider the following physical quantities :

Energy, power, pressure, impulse, temperature, gravitational potential

Which of the above is/ are the vector quantity / quantities?

Correct Answer: (a) Impulse only
Solution:Vector is defined as a quantity that has both magnitude and direction. The product of vector and scalar is always a vector. We know that impulse is, J = F. Δt = Δp, where F is force At is time duration and Ap is changing in momentum. Since momentum is a vector quantity, therefore impulse is also a vector quantity.

Sometimes the area can also be treated as vector direction of area vector is perpendicular to its plane. The S.I. unit of impulse is a kilogram meter per second. Therefore, the correct option is (a).

40. A piece of stone tied to a string is made to revolve in a circular orbit of radius r with other end of the string as the centre. If the string breaks, the stone will :

Correct Answer: (c) move along a tangent
Solution:A piece of stone tied to a string is made to revolve in a circular orbit of radius r with the other end of the string as the centre. Such type of motion is uniform circular motion. The direction of the acceleration is inward toward the centre of the circular path.

In a circular motion, the velocity is always tangential to the circular path. If the string breaks, the stone will move along a tangent. Therefore, the correct option is (c).
