Railway GK Questions 2026

The correct answer is C-DAC. The Centre for Development of Advanced Computing showcased its AUM HPC-AI processor and the RUDRA-AUM compute node, reflecting India's push to build indigenous capability in high-performance computing and AI at the system level, not just the chip level. C-DAC also displayed its indigenous 64-bit RISC-V processor, built on the open RISC-V architecture, which powers products such as Aheesa Technology's 1 Gbps connectivity device.

ISRO builds satellites and launch vehicles, DRDO develops defence systems and BEL is a defence electronics manufacturer; none of them made these processors. C-DAC, under the Ministry of Electronics and IT, is India's supercomputing agency, known for the PARAM series, which is why it leads the processor work. Other Indian names at the show included InCore Semiconductors for RISC-V processor IP and Netrasemi for AI surveillance chips.

The correct answer is ₹1,27,500 crore. Semicon 2.0 was approved by the Union Cabinet in July 2026 with this outlay. It builds on Semicon 1.0 and rests on six pillars: design; machines and materials; more fabs; advanced packaging; research and development; and talent development. The broader approach, covering the whole value chain rather than fabrication alone, was the point of the "Silicon to Systems" theme.

₹1.64 lakh crore is the trap: that is the investment commitment already made under the Semicon India Programme, across 12 approved projects in six States, three of which are in commercial production. ₹76,000 crore was the outlay of the original programme, and ₹1 lakh crore is a round-number distractor. Keep the two 2026 figures apart: ₹1,27,500 crore is the new government outlay, ₹1.64 lakh crore is investment committed by companies.

The correct answer is Yashobhoomi, New Delhi. The fifth edition of SEMICON India ran there for three days, from 17 to 19 September 2026, on the theme "Silicon to Systems: Building the Ecosystem", with more than 600 exhibiting companies, a Start-up Pavilion, a Workforce Development Pavilion, country and State pavilions and a hackathon.

Bharat Mandapam is the tempting wrong answer because it is Delhi's other big convention centre and hosted several 2026 events, including the India International Water Week that opened on 22 September. Mahatma Mandir in Gandhinagar hosts Vibrant Gujarat, and BIEC in Bengaluru hosts Aero India. Yashobhoomi, in Dwarka, is the India International Convention and Expo Centre in the capital's west. Keep the venue and theme together for this one.

The correct answer is All senior citizens aged 70 and above. On 11 September 2024 the Government extended AB PM-JAY to everyone aged 70 and above, regardless of income, covering about 6 crore senior citizens. They receive the Ayushman Vay Vandana card, and more than 1.36 crore such cards had been issued by 21 September 2026.

ASHA workers are the distractor: about 37 lakh families of ASHAs, anganwadi workers and helpers were indeed added, but earlier, in March 2024, and through a separate decision. Construction workers join through the Building and Other Construction Workers boards, and students are not a category at all. The name is easy to place: "Vay" refers to age, so the Vay Vandana card is the one for the elderly.

The correct answer is Socio-Economic Caste Census (SECC) 2011. Rural families qualify under six deprivation criteria of the SECC 2011, such as households with only one kucha room, no adult member between 16 and 59, female-headed households without an adult male, households with a disabled member, SC/ST households and landless households dependent on casual manual labour. Urban families qualify under 11 occupational categories, from rag pickers and domestic workers to construction workers and drivers.

Census 2011 is the tempting wrong answer: the SECC was a separate exercise from the population census. The National Family Health Survey is a health survey, not an eligibility list, and Aadhaar is an identity number, not a poverty database. Families once covered under the Rashtriya Swasthya Bima Yojana are included too.

The correct answer is ₹5 lakh. AB PM-JAY provides cashless hospitalisation cover of up to ₹5 lakh per family per year, covering 1,961 procedures across 27 medical specialties at public and private empanelled hospitals. The cover is per family, not per person, and there is no cap on family size or age.

The other amounts are distractors. The scale of use is worth remembering: by its eighth anniversary the scheme had funded about 13.25 crore hospital admissions worth ₹2.03 lakh crore, and over 48.51 crore people, about 33% of the population, held Ayushman cards. The Union Budget for 2026-27 provides ₹9,500 crore for it. A typical example in the backgrounder is a 65-year-old woman from Haryana whose hip surgery costing ₹44,140 was done free under the scheme.

The correct answer is 23 September 2018. AB PM-JAY was launched on that date to move India towards universal health coverage, and the PIB backgrounder of 22 September 2026 marks its eighth anniversary. It gives eligible families cashless hospital cover of up to ₹5 lakh a year for secondary and tertiary care through more than 38,000 empanelled hospitals.

The other dates are distractors around well-known days: 15 August is Independence Day, 2 October is Gandhi Jayanti and 1 April is the start of the financial year. Two later dates matter for this scheme and are worth keeping separate: March 2024, when about 37 lakh families of ASHAs and anganwadi workers were added, and 11 September 2024, when all senior citizens aged 70 and above were brought in through the Ayushman Vay Vandana card.

The correct answer is once. The Preamble has been amended only one time, by the 42nd Constitutional Amendment Act, 1976. That amendment added three words: "Socialist" and "Secular" to the description of India, and "Integrity" to the phrase "unity and integrity of the Nation".

"Never" is wrong because the 1976 change is on record; it is also why the Preamble as quoted today differs from the text adopted on 26 November 1949, which described India only as a "sovereign democratic republic". "Twice" and "three times" confuse the number of amendments with the number of words added, which is three. Keep the two numbers apart: one amendment, three words. The fact that the Preamble can be amended at all was settled by the Supreme Court in the Kesavananda Bharati case (1973), which held that it is a part of the Constitution and can be amended so long as its basic features are not destroyed.

The correct answer is N.A. Palkhivala. Nani Ardeshir Palkhivala, one of India's most eminent jurists and constitutional lawyers, called the Preamble the "identity card of the Constitution", because it tells us in one sentence what the Constitution is, where its authority comes from and what it sets out to achieve.

The other names are linked to different descriptions, and examiners use them precisely because they sound right. K.M. Munshi, a member of the Drafting Committee, called the Preamble the "political horoscope" of the sovereign democratic republic. Sir Ernest Barker, the British political scientist, described it as the "key-note" of the Constitution. Dr B.R. Ambedkar chaired the Drafting Committee, and his best-known description is of Article 32, which he called the heart and soul of the Constitution. Learn these as pairs, because questions often give the phrase and ask for the person, or the other way round.

The correct answer is A guiding principle for interpretation. The Preamble is not enforceable in a court of law: it is neither a source of power for the legislature nor a limit on its powers. Its main legal use is as an aid to interpretation. When the meaning of a provision of the Constitution is unclear, courts look to the Preamble to understand the objectives the framers had in mind.

The other options describe things the Preamble is not. It is not a schedule: the Constitution's schedules are separate lists placed at the end of the text, such as the list of languages. It is not a financial guideline. And it is not an enforceable part of law, which is the most tempting wrong answer: even after the Kesavananda Bharati case (1973) held that the Preamble is a part of the Constitution, it remained non-justiciable. Being part of the Constitution and being enforceable in court are two different things, and this question tests exactly that difference.

The correct answer is the Kesavananda Bharati case (1973). In the Berubari Union case of 1960 the Supreme Court had said that the Preamble is not a part of the Constitution, though it is a key to the minds of its makers. In Kesavananda Bharati the Court rejected that view and held that the Preamble is a part of the Constitution and can be amended, provided its basic features are not changed.

The Berubari Union case is the earlier decision that was reversed, so it cannot be the answer. The LIC of India case of 1995 came later and only reaffirmed that the Preamble is an integral part of the Constitution; it did not reverse anything. The Golaknath case of 1967 concerned Parliament's power to amend Fundamental Rights, not the status of the Preamble. The word "reverse" in the question is the clue: it points to the case that overturned Berubari, which is Kesavananda Bharati.

The correct answer is the Russian Revolution. The ideal of justice in the Preamble, described as social, economic and political, was inspired by the Russian Revolution of 1917, which is why books often list the former USSR as its source. It sits alongside the three objectives drawn from France.

The French Revolution is the source of liberty, equality and fraternity, the other three objectives, so it is the most tempting wrong answer. The American connection is to the idea of having a preamble at all, taken from the Constitution of the United States, not to the ideal of justice. The Magna Carta is a landmark of English constitutional history but is not the source of anything in the Preamble. A good way to remember the split: of the four objectives, justice points east, to Russia, while liberty, equality and fraternity point west, to France.

The correct answer is France. The ideals of liberty, equality and fraternity in the Preamble were taken from France, where they were the watchwords of the French Revolution. France is also the source of the idea of a republic.

The other options gave India different features. The United Kingdom is the source of parliamentary government, the rule of law, the cabinet system and single citizenship. Canada gave the idea of a federation with a strong Centre and residuary powers vested in the Centre. Ireland gave the Directive Principles of State Policy and the method of electing the President. The ideal of justice in the Preamble, the fourth of its objectives, has a different source again: the Russian Revolution. So of the four objectives, three (liberty, equality and fraternity) trace to France and one (justice) traces to the former USSR, a split that examiners like to test.

The correct answer is United States of America. The idea of beginning a constitution with a preamble was borrowed from the Constitution of the USA, whose own text opens with the words "We the People". The content of India's Preamble, however, comes from Jawaharlal Nehru's Objectives Resolution, moved in the Constituent Assembly on 13 December 1946 and adopted on 22 January 1947.

The other countries are sources of different parts of the Preamble or of the Constitution. The USSR is the source of the ideal of social, economic and political justice. Britain gave parliamentary government, the rule of law and single citizenship. Canada gave the model of a federation with a strong Centre. Be careful to separate two different questions that look alike: the idea of having a preamble came from the USA, while the ideals of liberty, equality and fraternity written inside it came from the French Revolution.

The correct answer is Liberty of thought, expression, belief, faith and worship. These are the exact words the Preamble uses for liberty, and they appear in it just as written here.

Each of the other options changes one word of the real text, which is exactly how this question catches people. The Preamble speaks of fraternity "assuring the dignity of the individual" and the unity and integrity of the Nation, not "human dignity". It promises equality "of status and of opportunity", not of status and employment. And justice in the Preamble is "social, economic and political"; the word "administrative" does not appear. When an option looks almost right, compare it word for word with the text: justice (social, economic, political), liberty (thought, expression, belief, faith, worship), equality (status, opportunity) and fraternity (dignity of the individual, unity and integrity of the Nation).

The correct answer is Socialist. The 42nd Constitutional Amendment Act, 1976 added three words to the Preamble: "Socialist" and "Secular" to the description of India, and "Integrity" to the phrase "unity and integrity of the Nation". It is the only amendment ever made to the Preamble.

Democratic, Republic and Sovereign were all in the Preamble from the start: as adopted on 26 November 1949, it described India as a "sovereign democratic republic". That is why they are wrong here. Questions on this amendment come in several forms: which word was added, which word was not added, or how many words were added. Keep all three in mind together: Socialist, Secular and Integrity, added in 1976. A related fact worth linking is the Kesavananda Bharati case of 1973, which had held three years earlier that the Preamble is part of the Constitution and can be amended without changing its basic features.

The correct answer is Sovereign, socialist, secular, democratic, republic. This is the order in which the Preamble describes India: "a SOVEREIGN SOCIALIST SECULAR DEMOCRATIC REPUBLIC". Socialist and secular were inserted between sovereign and democratic by the 42nd Amendment in 1976; before that the phrase read "sovereign democratic republic".

The first option swaps socialist and secular, which is the most common slip, since both words were added at the same time. The third option repeats "secular" and begins with the wrong word, and the fourth moves "sovereign" from the front to the end. A simple way to hold the order is to say the three S-words by sound: So, So, Se (Sovereign, Socialist, Secular), followed by the original last two words, Democratic Republic. The two words added in 1976 sit together in the middle.

The correct answer is The People of India. The Preamble opens with the words "We, the people of India", which name the people as the source from which the Constitution draws its authority. The Constitution was not handed down by a government, a court or a legislature; the people, through their Constituent Assembly, adopted, enacted and gave it to themselves on 26 November 1949.

The Supreme Court, the Indian Parliament and the Central Government are all created by the Constitution, so none of them can be its source of authority. Each of them exercises only the powers the Constitution gives it. This is the first of the four things the Preamble tells us, the others being the nature of the Indian State (sovereign, socialist, secular, democratic, republic), its objectives (justice, liberty, equality and fraternity) and the date of adoption. A fill-in-the-blank question like this one tests whether you know the exact opening words, so learn the text as written.

The correct answer is Jamnagar. The WHO Global Traditional Medicine Centre is in Jamnagar, Gujarat, and the PIB backgrounder describes it as a primary research and policy hub for traditional medicine. The Union Budget 2026-27 announced its upgrade to promote evidence-based research and global outreach.

The other cities are distractors, though each has some link with Ayush. Pune has well-known Ayurveda and naturopathy institutions, Jaipur hosts the National Institute of Ayurveda, and Varanasi is known for its Ayurveda faculty at Banaras Hindu University. The only WHO centre of this kind in the world is at Jamnagar. India's other global steps include hosting the Second WHO Global Summit on Traditional Medicine at Bharat Mandapam in December 2025, which adopted the Delhi Declaration, and the Ayush visa, M-3 for patients and M-4 for attendants.

The correct answer is ₹4,408 crore. According to the PIB backgrounder on the 11th Ayurveda Day, the Union Budget 2026-27 allocated ₹4,408 crore to the Ministry of Ayush to strengthen Ayush healthcare, promote evidence-based research and innovation, and build infrastructure and global outreach.

The other figures are distractors. The Budget also announced three specific steps worth remembering: the setting up of three new All India Institutes of Ayurveda to strengthen education, clinical services and research; the upgrading of Ayush pharmacies and drug-testing laboratories for quality and standardisation; and the upgrading of the WHO Global Traditional Medicine Centre at Jamnagar in Gujarat. Separately, the National Ayush Mission released over ₹6,406.99 crore to States and UTs between FY 2014-15 and FY 2025-26.
