Correct Answer: C [ Only 1 & 3 ]
Notes:
The Indo-Gangetic belt is the world’s most extensive expanse of uninterrupted alluvium formed by the deposition of silt by the numerous rivers. The Bangar belt consists of older alluvium and forms the alluvial terrace of the flood plains. In the Gangetic plains, it has a low upland covered by laterite deposits. The Khadar belt lies in lowland areas after the Bangar belt. It is made up of fresh newer alluvium which is deposited by the rivers flowing down the plain.

20. A 10 Kg block of Iron has which of the following twice in value in comparison to a 5 Kg block of Iron?
- Inertia
- Mass
- Volume
Select the correct option from the codes given below:
[A] Only 1 & 2
[B] Only 2
[C] Only 1 & 3
[D] 1, 2 & 3
Show Answer
Correct Answer: D [ 1, 2 & 3 ]
Notes:All three options are correct:
- Inertia: The 10 kg block of iron will have twice the inertia of the 5 kg block of iron because inertia is directly proportional to mass.
- Mass: The 10 kg block of iron has twice the mass of the 5 kg block of iron.
- Volume: Assuming the density of the iron remains the same, the 10 kg block of iron will have twice the volume of the 5 kg block of iron. This is because density is defined as mass per unit volume, and if mass doubles while density remains constant, volume will also double.
So, all three properties, inertia, mass, and volume, will be twice in value for the 10 kg block compared to the 5 kg block of iron.
21. Which of the following is / are correct statements with respect to Copper (Cu), Silver (Ag) and Gold (Au)?
- All of them are can be found naturally in their elemental state
- All of them belong to same group in the periodic table
Select the correct option from the codes given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 nor 2
Show Answer
Correct Answer: C [Both 1 & 2 ]
Notes:
The elements Copper (atomic number 29), silver (atomic number 47), and gold (atomic number 79), are three of the few metals that can be found naturally in their elemental state. These three metals have found great use as coins and jewellery for a number of reasons, including their resistance to corrosion and their remarkable colors. They are all in the same group in the periodic table (group 11), which suggests they should have similar—though not identical—properties.
22. Consider the following statements regarding Black Holes:
- A black hole is a supergiant star that has collapsed into itself
- The Black-hole singularity has zero radius
Which of the above is / are correct statements?
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 nor 2
Show Answer
Correct Answer: A [ Only 1 ]
Notes:
Black holes are indeed the remnants of massive stars that have collapsed, but they can also form from the merging of smaller black holes. The singularity is a point in the center of a black hole where the laws of physics as we know them break down, and the density becomes infinite. The singularity is surrounded by the event horizon, which marks the boundary beyond which anything that gets too close is pulled in and cannot escape.
Black hole singularity does not have a physical size or radius. Instead, it is considered to be a point-like object of zero size, or a mathematical singularity, at which the laws of physics break down and the density becomes infinite. The concept of the singularity is still not fully understood, and it remains a subject of active research in physics and astrophysics.
23. With reference to Attorney General and Advocate General, consider the following statements:
1. Highest Law officer of India is Attorney General
2. Highest Law officer of a State in India is Advocate General

[B] Only 2
[C] Both 1 & 2
[D] Neither 1 nor 2
Show Answer
Correct Answer: C [ Both 1 & 2 ]
Notes:
While Attorney General is highest law officer of India, Advocate General is the highest law officer of any state in India. Both of these are constitutonal posts.
24. Which of the following can be logically concluded from the fact that “
atomic number of Iron is 26”?
- Iron has same number of Protons and Neutrons
- Iron has 26 Protons
- All atoms which contain 26 protons are iron atoms
Select the correct option from the codes given below:
[A] Only 1 & 2
[B] Only 2 & 3
[C] Only 1 & 3
[D] 1, 2 & 3
Show Answer
Correct Answer: B [ Only 2 & 3 ]
Notes:
The atomic number of an atom and its number of protons are the same. Thus, there are 26 protons in an iron atom. Another way to put this is that all atoms that contain 26 protons are, by definition, iron atoms.
25. A Gold Ring which is 50% pure. Its purity can be alternatively shown as __:
[A] 18 Carat
[B] 18 Karat
[C] 12 Carat
[D] 12 Karat
Show Answer
Correct Answer: D [ 12 Karat ]
Notes:
The carat is the common unit used to describe the mass of a gem. A 1-carat diamond, for example, has a mass of 0.20 g. The karat is the common unit used to describe the purity of a precious metal, such as gold. A 24-karat gold ring is as pure as can be. A gold ring that is 50 % pure is 12 karat.
