Financial distribution between Union and states takes place on the basis of the recommendations of the?
A)
NITI-Aayog
B)
Planning commission
C)
Finance Commission
D)
National Development Council
The correct answer is **Finance Commission**. Under Article 280 of the Indian Constitution, the Finance Commission is constituted to recommend the distribution of tax revenues between the Union and the States, as well as other fiscal matters like grants-in-aid. Hence, financial distribution between the Union and states is based on its recommendations.
Why the others are incorrect:
- **Planning Commission**: It used to prepare five-year plans and allocate plan funds, but it was not the constitutional body for tax revenue distribution.
- **NITI Aayog**: It replaced the Planning Commission and acts as a नीति/strategy think tank; it does not decide constitutional fiscal devolution.
- **National Development Council**: It was an advisory body for plan approval and coordination, not for financial distribution between Union and States.
The world’s largest exporter of Cars in the year 2022-23 is
A)
Japan
B)
China
C)
USA
D)
Germany
Japan is the world’s largest exporter of cars in 2022–23, supported by international trade data showing Japan leading global automobile exports. Germany, the USA, and China are major car exporters, but they were behind Japan in that period. Germany is a strong exporter of premium vehicles, the USA exports many vehicles but not the most globally, and China has rapidly grown in auto exports but was still not the top exporter for 2022–23.

B)
The Prime Minister of India
C)
Finance Minister of India
D)
Governor of RBI
The ex-officio chairman of NITI Aayog is the Prime Minister of India, who heads the institution by virtue of holding that office. NITI Aayog was created to replace the Planning Commission, and its leadership structure places the Prime Minister as its chairperson. The other options are incorrect: the President of India is the constitutional head of the state but does not chair NITI Aayog; the Finance Minister is not the ex-officio chairman; and the Governor of RBI has no role in heading NITI Aayog.
What is the increased productivity of ponds and lakes due to excess nutrients called?
A)
Bio-magnification
B)
Extinction
C)
Eutrophication
D)
Sedimentation
The correct answer is **Eutrophication**. It refers to the enrichment of ponds, lakes, or other water bodies with excess nutrients (mainly nitrogen and phosphorus), which causes excessive growth of algae and aquatic plants and increases biological productivity.
Why the others are incorrect:
- **Bio-magnification**: This is the progressive increase in concentration of toxic substances in organisms at higher trophic levels, not nutrient-driven productivity.
- **Extinction**: This means the complete disappearance of a species, unrelated to water body productivity.
- **Sedimentation**: This is the settling of suspended particles at the bottom of a water body; it does not mean increased productivity due to nutrients.
Substance which offers no resistance when cooled to its critical temperature are called
A)
Superconductors
B)
Superfluids
C)
Semi-conductors
D)
Conductive cells
The correct answer is **superconductors**. A material that, when cooled below its **critical temperature**, offers **zero electrical resistance** is called a superconductor. This is the defining property of superconductivity.
Why the others are incorrect:
- **Superfluids**: These are fluids that flow with zero viscosity, not zero electrical resistance.
- **Semi-conductors**: These have conductivity between conductors and insulators, but they do not become zero-resistance materials at a critical temperature.
- **Conductive cells**: This is not a standard term for materials with zero resistance in physics or engineering.

A)
Japan
B)
South Korea
C)
Australia
D)
India
The Quad (Quadrilateral Security Dialogue) consists of India, Japan, Australia, and the United States. Therefore, South Korea is not part of the Quad, making option b correct. The other options are incorrect because India, Australia, and Japan are all official members of the Quad.
Who administered the oath of office to the president of India?
A)
Chief justice of India
B)
Speaker of Lok Sabha
C)
Prime Minister
D)
Vice-president
The oath of office to the President of India is administered by the Chief Justice of India, or in his absence, the senior-most judge of the Supreme Court available. Therefore, option (a) is correct. The Prime Minister does not administer the presidential oath; the Vice-President is not the oath-giver for the President; and the Speaker of the Lok Sabha has no constitutional role in this ceremony.
With which country does India conduct a bilateral joint military exercise called the ‘VINBAX Exercise’?
A)
Japan
B)
Vietnam
C)
Russia
D)
Phillipines
VINBAX is the India–Vietnam bilateral joint military exercise. The name itself reflects the two countries: "VIN" for Vietnam and "BAX" for India’s Army exercise format. Therefore, option (b) Vietnam is correct. The other options are incorrect because India does not conduct an exercise called VINBAX with the Philippines, Russia, or Japan; those countries have different bilateral or multilateral exercises with India.
Recently, Siddaramaiah took oath as the chief minister of
A)
Karnataka
B)
Uttarakhand
C)
Goa
D)
Madhya Pradesh
Siddaramaiah recently took oath as the Chief Minister of Karnataka, so option (a) is correct. The other options are incorrect because Uttarakhand, Goa, and Madhya Pradesh are different Indian states and Siddaramaiah did not take oath as their Chief Minister.
Which Article of the Indian constitutional is automatically suspended during emergency proclamation by the president?
A)
Article 17
B)
Article 18
C)
Article 19
D)
Article 21
Article 19 is the one that can be automatically suspended during a National Emergency proclaimed by the President under Article 352, but only when the emergency is declared on grounds of war or external aggression. During such an emergency, the six freedoms under Article 19 are suspended for the duration of the emergency.
Why the others are incorrect: Article 18 abolishes titles and is not suspended during emergency; Article 17 abolishes untouchability and remains enforceable; Article 21 (right to life and personal liberty) is not automatically suspended—its suspension requires a separate constitutional provision and, after the 44th Amendment, it cannot be suspended even during emergency except as permitted by law.
In a pressure cooker, cooking is faster because the increase in vapor pressure
A)
Increases the specific heat
B)
Increases the boiling point
C)
Decreases the boiling point
D)
Decreases the specific heat
In a pressure cooker, the pressure above the water is increased, so the boiling point of water rises. Because the water and steam can reach a temperature higher than 100°C before boiling, food cooks at a higher temperature and therefore faster. Option (b) is correct.
Why the others are wrong: (c) is opposite of what happens—the boiling point increases, not decreases. (a) and (d) are incorrect because specific heat is not the reason cooking becomes faster in a pressure cooker; the key effect is the rise in boiling point due to increased pressure.
Which article of the Indian constitution contains Right to Education (RTE)?
A)
Article 20 A
B)
Article 21 A
C)
Article 14
D)
Article 17
Article 21A of the Indian Constitution guarantees the Right to Education (RTE) for children aged 6 to 14 years. It was inserted by the 86th Constitutional Amendment Act, 2002. Option (a) is incorrect because Article 20A does not exist in the Constitution. Option (c), Article 14, guarantees equality before the law, not education. Option (d), Article 17, abolishes untouchability, so it is unrelated to the Right to Education.

A)
Serena Williams
B)
Danielle Collins
C)
Aryna Sabalenka
D)
Ashleigh Barty
Aryna Sabalenka won the women’s singles title at the 2023 Australian Open, defeating Elena Rybakina in the final. Therefore, option (c) is correct. The other options are incorrect because Ashleigh Barty had retired before the 2023 tournament, Serena Williams did not win the 2023 Australian Open, and Danielle Collins was not the champion that year.
Year 1921 is known as the year of great divide in India’s population history because
A)
India’s population was divided into Pakistani Indians and Mainland Indians
B)
It was the year India was divided into religious line viz,.Hindu and Muslim
C)
The population of India decreased in that year from last census and after that it continues to increase.
D)
The great idea of complete independence from the British colonization was put into force in that year.
Option (c) is correct. The year 1921 is called the "year of great divide" in India’s population history because the Census of 1921 recorded a decline in population compared to the previous census, and from 1921 onward India’s population began to increase steadily. This marks a major turning point in demographic trends.
Option (a) is incorrect because India was not divided into Pakistani and mainland Indians in 1921; Partition happened in 1947.
Option (b) is incorrect because 1921 was not a division of population into Hindu and Muslim lines.
Option (d) is incorrect because the idea of complete independence from British rule was not put into force in 1921; the freedom struggle intensified later, and independence was achieved in 1947.
Which one among the following radiations carries maximum energy?
A)
X-Rays
B)
Infra-red Rays
C)
Ultra-violet Rays
D)
Gamma Rays
Gamma rays carry the maximum energy among the given radiations because electromagnetic wave energy is directly proportional to frequency (E = h\nu) and inversely proportional to wavelength. Gamma rays have the highest frequency and shortest wavelength in the electromagnetic spectrum, so they have the greatest energy. Infra-red rays have much lower frequency and energy than visible/UV/X-rays. Ultra-violet rays have more energy than visible light but less than X-rays and gamma rays. X-rays are high-energy, but gamma rays are still higher in frequency and energy than X-rays.

C)
Germany
D)
Iran
The Kh-47M2 Kinzhal is a Russian hypersonic air-launched ballistic missile developed and produced by Russia. It is carried by Russian aircraft such as the MiG-31K and can be equipped with conventional or nuclear warheads. The other options are incorrect because the USA, Germany, and Iran are not the producers of the Kinzhal missile.
Which city had bagged the first rank in the National Water Award 2022?
A)
Chandigarh
B)
Gangtok
C)
Ahmedabad
D)
Shimla
Chandigarh bagged the first rank in the National Water Award 2022 in the category of Best Urban Local Body. Hence, option (a) is correct. Ahmedabad, Gangtok, and Shimla were not the first-rank city for this award category in 2022, so options (c), (b), and (d) are incorrect.
The Board of Control for Cricket in India (BCCI) has announced a multi-year partnership with which of the following company as the official kit sponsor for the Indian Cricket Team
A)
Nike
B)
Adidas
C)
Levi’s
D)
Reliance-Jio
BCCI announced a multi-year partnership with Adidas as the official kit sponsor for the Indian Cricket Team, so option (b) is correct. Nike is incorrect because it was the previous kit sponsor, not the newly announced one. Reliance-Jio is a telecom company and Levi’s is an apparel brand, but neither was appointed as the official kit sponsor for the Indian Cricket Team in this announcement.
The number of trees in each row of a garden is equal to the total number of rows in the garden. After 111 trees have been uprooted in the storm, there remain 10914 trees in the garden. The number of rows of trees in the garden is
A)
100
B)
105
C)
110
D)
115
Let the number of rows be x. Since the number of trees in each row is also x, the total number of trees originally was x^2. After 111 trees were uprooted, 10914 trees remained, so:
x^2 - 111 = 10914
x^2 = 11025
x = 105
So, the number of rows is 105, which is option b.
Why the others are incorrect:
- a) 100 gives 100^2 = 10000, not 11025.
- c) 110 gives 110^2 = 12100, not 11025.
- d) 115 gives 115^2 = 13225, not 11025.
Which one of the following is also called Stranger gas?
A)
Argon
B)
Neon
C)
Nitrous Oxide
D)
Xenon
Xenon is also called the "stranger gas" because it was historically considered a rare, unusual constituent of the atmosphere and was difficult to detect. Among the noble gases, xenon is the one commonly associated with this nickname. Argon is known as an inert gas, neon is known for neon lighting, and nitrous oxide is not a noble gas at all; it is a compound gas used as an anesthetic and in whipped cream chargers.
