State Exams 2020 Previous Year GK Questions with Answers

The correct answer is B, 1938. Subhash Chandra Bose was elected president of the Indian National Congress at the Haripura session in Gujarat in 1938, where he set up a National Planning Committee under Jawaharlal Nehru. He was elected a second time at Tripuri in 1939, defeating Pattabhi Sitaramayya, but resigned in April of that year after losing the confidence of the working committee, and went on to found the Forward Bloc. Option A, 1932, is the year of the Communal Award and the Poona Pact and has no connection with his presidency. Option C, 1941, is the year Bose escaped from house arrest in Calcutta and made his way to Germany. Option D, 1943, is the year he took charge of the Indian National Army at Singapore and proclaimed the Azad Hind government, which is the fact most often confused with the presidency.

The correct answer is B, A-4, B-3, C-1, D-2. Nyaya is the school of logic and holds that liberation follows from correct reasoning, so it pairs with logical thinking. Mimamsa treats the ritual portion of the Vedas as binding and holds that salvation comes from performing Vedic rituals. Samkhya teaches that bondage ends with the acquisition of real knowledge, namely the discrimination of purusha from prakriti. Vedanta rests on the Upanishads and holds that liberation comes from knowledge of the self as identical with Brahman. Option A is wrong because it assigns knowledge of the self to Nyaya and logical thinking to Mimamsa, reversing both. Option C is wrong because it gives Nyaya the acquisition of real knowledge, which belongs to Samkhya. Option D is wrong because it makes Nyaya the school of Vedic ritual, a pairing that belongs to Mimamsa alone.

The correct answer is D, Gautam Buddha. The eightfold path or ashtangika marga is the fourth of the noble truths preached by the Buddha in his first sermon at Sarnath, and it names the middle way between indulgence and mortification: right view, right intention, right speech, right action, right livelihood, right effort, right mindfulness and right concentration. Option A, Shankaracharya, taught Advaita Vedanta, in which liberation comes from the knowledge that Brahman alone is real; he set out no eightfold path. Option B, Mahavir Swami, taught the triratna of right faith, right knowledge and right conduct and five great vows, so his scheme is threefold and fivefold, not eightfold. Option C, Ramanuja, taught Vishishtadvaita and the path of devotion or prapatti. Candidates also confuse this path with the eight limbs of Patanjali's yoga, which are yama to samadhi and belong to a different tradition.

The correct answer is D, only 3. The chairman of the Union Public Service Commission is removed by the President under Article 317, and for misbehaviour only after the Supreme Court has held an inquiry on the President's reference and reported against him. No resolution of either House is needed at any stage, so Parliament has no role at all. Judges of the High Courts and of the Supreme Court, listed at 1 and 2, are removed by the President only after an address supported by a special majority of each House, so Parliament is central there. The Comptroller and Auditor General at 4 is removed in the same manner as a judge of the Supreme Court, which again requires an address by both Houses. Options A, B and C are wrong because each of them leaves out the UPSC chairman or wrongly brings in the judges or the CAG.

The correct answer is D, the assertion is false but the reason is true. Ahmedabad is a very large cotton textile centre and is called the Manchester of India, but it is not the largest in the country; that place belongs to Mumbai, the old Cottonopolis, which grew first because of its port, its mills and its capital, and Maharashtra remains ahead of Gujarat in the industry. The reason, however, is a correct statement in itself: Ahmedabad lies in the black soil tract of Gujarat where cotton is grown in quantity, so raw material has never been a constraint there. Options A and B both treat the assertion as true, which it is not. Option C reverses the position by calling the reason false, although Gujarat is indeed a leading cotton-growing state.

The correct answer is D, State Bank of India. YONO, which stands for You Only Need One, was launched by the State Bank of India as a single application for banking, investment, insurance and online shopping, and it also allows cash withdrawal at the bank's machines without a card. Option A is wrong because HDFC Bank offers its own mobile banking and payment applications under different names. Option B is wrong because Punjab National Bank runs its own digital platform and is not connected with YONO. Option C is wrong because ICICI Bank has its own application as well. Questions on bank applications are answered by holding the app and the bank together as a pair, exactly as the folk forms are held with their states in another subject.

The correct answer is D, lower. A geothermal plant takes steam or hot water from a natural underground reservoir, whose temperature is set by the rock and rarely approaches what a furnace can produce, so both the temperature and the pressure at the turbine are well below those of a coal-fired steam plant, and the thermal efficiency is correspondingly lower. Options B and C are wrong for the same reason: no natural reservoir is hotter than a boiler fired deliberately, and quoting higher values confuses the depth of the source with its temperature. Option A is wrong because the two are not comparable either; the gap is large enough that geothermal turbines are designed differently, often working on a separate fluid that boils at a low temperature. What geothermal loses in efficiency it gains in fuel cost, which is nil, and in emissions.

The correct answer is B, Nizamuddin Auliya. Amir Khusrau served as a poet at the courts of several Delhi Sultans, but his spiritual allegiance was to Nizamuddin Auliya, and he was buried beside his master. He is called the Tuti-i-Hind, the parrot of India, wrote works such as the Khazain-ul-Futuh and the Nuh Sipihr, composed in the early Hindavi speech from which Hindi and Urdu grew, and tradition credits him with shaping qawwali. Option A, Fariduddin Ganjshakar, was the master of Nizamuddin Auliya himself and belongs to an earlier generation at Ajodhan. Option C, Shaikh Salim Chishti, lived in the sixteenth century at Sikri, where Akbar built Fatehpur Sikri near his hospice, three centuries after Khusrau. Option D does not belong to the line of Chishti masters that examiners test.

The correct answer is A, 1992. SEBI first appeared in April 1988 as an administrative arrangement with no legal powers, and it became a statutory regulator when the Securities and Exchange Board of India Act was passed in 1992; the words quoted in the question are taken from the preamble of that Act, which speaks of protecting investors, promoting the development of the securities market and regulating it. Because the statutory body dates from the Act, 1992 is the year every examination expects. Option B, 1999, is the year the Central Depository Services Limited was set up, the second depository in India. Option C, 1987, and option D, 1985, come before even the administrative body existed. Keep the sequence in mind: the Securities Contracts (Regulation) Act of 1956, SEBI as an administrative body in 1988, the SEBI Act in 1992 and the Depositories Act in 1996.

The correct answer is B, Karnataka. Jog Falls is formed by the Sharavathi river where it drops off the edge of the Western Ghats in the Shivamogga district of Karnataka, and it falls in four separate streams traditionally named Raja, Rani, Rocket and Roarer. It is a segmented fall rather than a single plunge, and its flow depends on releases from the Linganamakki reservoir upstream. Option A, Uttarakhand, is a Himalayan state whose famous water features are glaciers and the sources of the Ganga and Yamuna rather than plateau-edge falls. Option C, Jharkhand, does have falls such as Hundru and Dassam on the Chota Nagpur plateau, but not Jog. Option D, Sikkim, has small Himalayan cascades. Remember that Karnataka also has Kunchikal on the Varahi, which is counted as the highest waterfall in India.

The correct answer is A, Marble. Marble is a non-metallic mineral: no metal can be drawn out of it, and it is used as a building and sculpting stone, the Makrana marble of Rajasthan being the stone of the Taj Mahal. Minerals are first divided into metallic and non-metallic. A metallic mineral yields a metal when smelted and is either ferrous, containing iron, or non-ferrous. A non-metallic mineral has no metal content of that kind, and limestone, mica, gypsum, dolomite, marble and rock salt are the common examples; marble itself is limestone changed by heat and pressure. B is wrong because manganese is a ferrous metallic mineral, used to harden steel and to make dry cells and paints. C is wrong because silver is a non-ferrous metallic mineral, used in jewellery, coins and electrical contacts. D is wrong because lead too is a non-ferrous metal, used in batteries and sheeting. Exam tip: metallic – ferrous such as iron and manganese, non-ferrous such as copper, lead, zinc and silver; non-metallic – limestone, mica, gypsum, marble.

The correct answer is D, Ninety days. Section 22 of the National Green Tribunal Act, 2010 allows a person aggrieved by an award, order or decision of the Tribunal to appeal to the Supreme Court within ninety days of the day it is communicated, and the Court may admit a later appeal if it is satisfied that there was sufficient cause for the delay. The Tribunal itself was created in 2010 to hear environmental cases quickly, with its principal bench at New Delhi, and it is expected to decide a case within six months. A is wrong because thirty days is the period within which a person may go to the Tribunal against an order of a body such as a State Pollution Control Board, not the period for an appeal to the Supreme Court. B and C are wrong because the Act fixes no limit of forty-five or sixty days for such an appeal. Exam tip: NGT Act 2010 – thirty days to appeal to the Tribunal, ninety days to appeal to the Supreme Court.

The correct answer is D, Black. In the colour code used for fire extinguishers, a black band or label marks a carbon dioxide extinguisher. The body of the cylinder is signal red and a coloured patch near the label tells you the filling at a glance, so the right cylinder can be picked in a hurry. A carbon dioxide extinguisher works by smothering: the gas is heavier than air, so it pushes oxygen away from the fuel, and it also chills the surface as it expands out of the horn. Because it does not conduct electricity and leaves no residue, it is the choice for live electrical equipment, switchboards, laboratories and computer rooms. Option A is wrong because a red band marks a plain water extinguisher, used on wood and paper fires. Option B is wrong because blue marks dry powder, the all-purpose filling for liquid and gas fires. Option C is wrong because cream, not white, is the colour for a foam extinguisher. Exam tip: red — water, cream — foam, blue — dry powder, black — carbon dioxide, yellow — wet chemical.

The correct answer is A, Used on ordinary combustibles such as wood and paper. Fires are sorted into classes by what is burning, and Class A covers ordinary solid fuels — wood, paper, cloth, straw, rubber and many plastics. These fires leave glowing embers, so they are put out mainly by cooling, and plain water or a water-based extinguisher is the cheapest and most effective choice for them. Option B is wrong because burning liquids such as petrol, kerosene, oil, paint and solvents are Class B, where water would spread the fire and foam or dry powder is used instead. Option C is wrong because a fire in live electrical equipment is a separate class — Class C in the American scheme and marked Class E in the Indian and European ones — and it needs a non-conducting agent such as carbon dioxide, never water. Option D is wrong because burning metals such as magnesium, sodium and potassium form Class D and need a special dry powder, since water reacts violently with them. Exam tip: A — solids, B — liquids, C — gases, D — metals, F or K — cooking oil.

The correct answer is A, Crown Gall. Crown gall is caused by the bacterium Agrobacterium tumefaciens, which enters through a wound near the base, or crown, of the stem and makes the plant grow rough tumour-like swellings there. The bacterium works by pushing a piece of its own Ti plasmid into the plant's cells and forcing them to divide, and that natural trick is why laboratories use it as a vector to carry new genes into plants. Grapevine, apple, rose, walnut and stone fruits suffer the most. Option B is wrong because mosaic diseases, such as tobacco mosaic, are caused by viruses that mottle the leaves in light and dark patches. Option C is wrong because smut of wheat, bajra and sugarcane is a fungal disease that fills the ear with black powdery spores. Option D is wrong because white blister, or white rust, of crucifers such as mustard is also fungal and raises white blisters on leaves and stems. Exam tip: bacterial — crown gall, citrus canker, bacterial blight of rice; viral — mosaic, leaf curl; fungal — smut, rust, blight.

The correct answer is D, Mizoram. Mizoram is a full state, not a Union Territory. It was carved out of Assam as a Union Territory in 1972, and after the Mizo Accord of 1986 it became a state on 20 February 1987 under the 53rd Constitutional Amendment, on the same day as Arunachal Pradesh. The difference matters: a Union Territory is administered by the President through an Administrator or Lieutenant Governor under Article 239, while a state has its own Governor and its own government under Part VI of the Constitution. Option A is wrong because Ladakh has been a Union Territory since 31 October 2019 and Puducherry since 1962, and both are listed as Union Territories in the First Schedule. Option B is wrong because Dadra and Nagar Haveli and Daman and Diu were joined into one Union Territory on 26 January 2020. Option C is wrong because Lakshadweep is a Union Territory of coral islands in the Arabian Sea, with its capital at Kavaratti. Exam tip: Mizoram and Arunachal Pradesh became states on 20 February 1987, Goa on 30 May 1987.

The correct answer is D, Areolar. Animal tissues are grouped into four kinds — epithelial, muscular, connective and nervous — and areolar is not one of them, because it is only a type of connective tissue. Areolar tissue is the loose packing tissue found between the skin and the muscles, around blood vessels and nerves and inside bone marrow, where it fills space, supports organs and helps repair damaged parts. Since it sits inside the connective group, putting it beside the four main classes is exactly the mistake the question wants you to catch. Option A is wrong because epithelial tissue is one of the four and covers and lines all body surfaces and cavities. Option B is wrong because muscular tissue, made of contractile fibres of three sorts — striated, smooth and cardiac — is also one of the four. Option C is wrong because connective tissue is a main class and takes in bone, cartilage, blood, tendon, ligament, adipose and areolar tissue itself. Exam tip: four animal tissues — epithelial, muscular, connective, nervous; blood, bone and areolar are all connective.

The correct answer is C, Potassium. A wet chemical extinguisher sprays a fine mist of a potassium salt solution — usually potassium acetate, potassium citrate or potassium carbonate — so potassium is the working element inside it. This type is built for kitchen fires of cooking oil and fat, which are put in Class F in the Indian and European scheme and Class K in the American one. It works in two ways at once: the mist cools the burning oil below the temperature at which it catches fire, and the potassium salt reacts with the hot fat to form a soapy foam layer on the surface. That reaction, called saponification, seals the oil off from oxygen so it cannot flare up again. Option A is wrong because copper is used in wiring and alloys and has no part in extinguishers. Option B is wrong because magnesium burns fiercely itself and is a fuel in metal fires, never a suppressant. Option D is wrong because phosphorus catches fire very easily and is used in matches. Exam tip: wet chemical — potassium salt, cooking-oil fires, works by saponification.

The correct answer is C, 18% Tungsten. High-speed steel is named 18-4-1 after the three metals added to it in that order: 18 per cent tungsten, 4 per cent chromium and 1 per cent vanadium, with iron making up the rest along with a little carbon. Tungsten is the heart of the alloy because it keeps the steel hard even when the cutting edge glows red hot, so drills, milling cutters and lathe tools made from it can cut at high speed without losing their edge. Chromium adds hardness and resistance to rust, and vanadium refines the grain and improves wear resistance. A is wrong because chromium in this grade is 4 per cent, not 1. B is wrong because the 18-4-1 grade has no nickel; nickel goes into stainless steel and into invar. D is wrong because vanadium is the 1 per cent part of the name. Exam tip: 18-4-1 means tungsten 18, chromium 4, vanadium 1.

The correct answer is C, Marwar. The Marwar school, the painting of the Jodhpur region, is the one credited with the illustrated Panchatantra series, a set painted at Pali in the early eighteenth century in which the animal fables are told frame by frame. Marwar work is known for its folk strength rather than courtly polish: bold flat colours, large staring eyes, sturdy figures and plenty of horses and camels. Alongside the Panchatantra, the school also illustrated the Dhola Maru romance and the Ragamala series. A is wrong because Bundi painting is famous for lush green landscapes, monsoon skies, lotus tanks and elephant scenes. B is wrong because Kota, which grew out of Bundi, is best known for its hunting scenes set in thick forest. D is wrong because Dhundhar, the Jaipur and Amber school, is known for large portraits, court scenes and its Ragamala and Bihari Satsai sets. Exam tip: Panchatantra and Dhola Maru go with Marwar, monsoon and greenery with Bundi, shikar with Kota.
