The Constituent Assembly adopted the Constitution on 26 November 1949, a date now observed as Constitution Day. The document came into force on 26 January 1950, which is celebrated as Republic Day. 9 December 1946 was the first sitting of the Assembly, and 15 August 1947 was Independence Day.
The Drafting Committee was constituted on 29 August 1947 with Dr B. R. Ambedkar as its Chairman. He presented the draft Constitution in the Assembly and is therefore called the chief architect of the Constitution. Rajendra Prasad presided over the Constituent Assembly itself.
Fundamental Duties were inserted by the 42nd Amendment Act, 1976, following the recommendations of the Swaran Singh Committee. Article 51A originally listed ten duties, and an eleventh was added by the 86th Amendment in 2002. The other committees dealt with Centre-State relations or Panchayati Raj.
Mandamus literally means 'we command' and directs a public authority to carry out a legal duty it has neglected. It cannot be issued against a private individual or against the President or Governors. Habeas corpus protects personal liberty, quo warranto questions the holding of public office, and certiorari quashes an order.
Article 110 read with Article 117 requires the President's prior recommendation for introducing a money bill. The bill must be introduced only in the Lok Sabha and is certified as a money bill by the Speaker. The Speaker certifies the bill but does not authorise its introduction.
The Tropic of Cancer passes through eight Indian states, including Rajasthan, Gujarat, Madhya Pradesh and Bihar. It crosses Rajasthan near Banswara and does not pass through Kerala, Odisha or Andhra Pradesh. The line also passes through Jharkhand, West Bengal, Chhattisgarh and Mizoram.
The Kosi rises in Tibet and Nepal and shifts its course frequently on the Bihar plains, causing severe floods, hence the name 'Sorrow of Bihar'. The Damodar is called the 'Sorrow of Bengal'. The Gandak, Son and Ghaghara are other tributaries of the Ganga system.
The Deccan Plateau is flanked by the Western Ghats along the Arabian Sea side and the Eastern Ghats along the Bay of Bengal side. The plateau is composed largely of basaltic lava and is separated from the northern plains by the Vindhya and Satpura ranges. The Aravalli and Karakoram lie far outside this region.
Black soil, also called regur, is formed from the weathering of basaltic lava on the Deccan trap and retains moisture well. Its clayey, self-ploughing character makes it ideal for cotton, so it is called black cotton soil. Alluvial soil suits rice and wheat, while laterite and desert soils are less suited to cotton.
Awadh was annexed in 1856 on the ground of alleged misgovernment, not strictly under the Doctrine of Lapse. The Doctrine of Lapse, associated with Lord Dalhousie, was applied earlier to Satara, Nagpur and Jhansi. The annexation of Awadh deepened resentment among sepoys, many of whom came from that region.
The Indian National Congress was founded in December 1885 in Bombay, with A. O. Hume playing the key founding role. W. C. Bonnerjee was its first President, not its founder. Dadabhai Naoroji and Gokhale were prominent early leaders of the organisation.
At Plassey in 1757, Robert Clive defeated Siraj-ud-Daulah, the Nawab of Bengal, aided by the defection of Mir Jafar. The victory established British political influence over Bengal. Mir Qasim later fought at Buxar, and Shuja-ud-Daulah was the Nawab of Awadh.
The Rowlatt Act empowered the government to arrest and detain persons without trial for up to two years, which Gandhi called a 'Black Act'. He launched a nationwide hartal against it in 1919, leading to the Jallianwala Bagh tragedy. Salt tax, the partition of Bengal and separate electorates relate to other measures.
Gandhi marched from Sabarmati Ashram to Dandi in March-April 1930 and made salt from seawater to defy the government's monopoly and tax on salt. This launched the Civil Disobedience Movement. The land revenue system, partition of Bengal and Rowlatt Act were separate grievances.
Article 17 abolishes untouchability and forbids its practice in any form, and the Protection of Civil Rights Act, 1955 gives it effect. Article 14 guarantees equality before the law, Article 15 prohibits discrimination and Article 21 protects life and personal liberty.
The RBI was established in 1935 as a private shareholders' bank and was nationalised on 1 January 1949. Nationalisation gave the government full control over the central bank's functions. 1955 relates to the nationalisation of the Imperial Bank into the State Bank of India, and 1969 to the nationalisation of fourteen commercial banks.
Income tax is a direct tax because its incidence and burden fall on the same person and it is paid directly to the government. GST, customs duty and excise duty are indirect taxes, where the burden can be shifted to the consumer. Direct taxes also include corporate tax and capital gains tax.
The Green Revolution of the 1960s and 1970s introduced high-yielding wheat and rice varieties, irrigation and fertilisers, sharply raising production, especially in Punjab and Haryana. M. S. Swaminathan is regarded as its chief architect in India. Jute, tea and cotton were not the focus of this programme.
Kharif crops are sown in June-July with the arrival of the monsoon and harvested in autumn; rice, maize, jowar and cotton are examples. Wheat, mustard and barley are Rabi crops sown in winter and harvested in spring. The distinction depends on the season and water availability.
Article 19 freedoms, including speech and expression, are available only to citizens. Articles 14, 20 and 21 apply to all persons, including foreigners. This distinction is important because citizenship-based rights cannot be claimed by non-citizens.
The 73rd Amendment Act, 1992 added Part IX and the Eleventh Schedule, giving constitutional status to Panchayati Raj institutions. It came into force in 1993 and mandated three-tier panchayats with reservations. The 74th Amendment did the same for urban local bodies.
A starred question is marked with an asterisk and requires an oral answer on the floor of the House, allowing supplementary questions. An unstarred question receives only a written answer. Short notice questions are asked with less than the prescribed notice.
Bangladesh shares the longest land border with India, about 4,096 km, followed by China at roughly 3,488 km. The India-Pakistan border is about 3,323 km and the India-Nepal border about 1,751 km. This makes Bangladesh India's most extensive land neighbour.
The Poona Pact followed Gandhi's fast against separate electorates for the Depressed Classes granted by the Communal Award. It provided for reserved seats within the general electorate instead of separate electorates. The pact did not deal with Punjab, princely states or the salt tax.
Shillong is the capital of Meghalaya, a fact that remains true despite the creation of separate hill states. Karnataka's capital is Bengaluru, Gujarat's is Gandhinagar and Punjab's is Chandigarh. Mysuru, Ahmedabad and Amritsar are major cities but not state capitals.
Indian Standard Time is based on the longitude 82°30'E, which passes near Mirzapur in Uttar Pradesh. This meridian is used as the reference for IST, which is 5 hours 30 minutes ahead of UTC.
Tamil is the official language of Tamil Nadu and is widely spoken there. The other pairs are mismatched: Kerala's official language is Malayalam, Karnataka's is Kannada, and Andhra Pradesh's is Telugu.
Sucheta Kripalani became the Chief Minister of Uttar Pradesh in 1963, making her the first woman to hold that office in any Indian state. Indira Gandhi was Prime Minister, not a Chief Minister, and the other leaders never served as Chief Minister.
The Ring of Fire is a horseshoe-shaped belt around the Pacific Ocean where many tectonic plate boundaries converge, causing frequent earthquakes and volcanic activity. The other oceans do not have such a concentrated belt of seismic and volcanic activity.
The Earth's structure consists of a thin crust, a thick mantle, a liquid outer core, and a solid inner core. This order reflects increasing depth and changes in composition and physical state.
The 86th Amendment Act, 2002 inserted Article 51A(k), making it a Fundamental Duty of parents or guardians to provide opportunities for education to their children aged six to fourteen. The other duties listed were part of the original Article 51A introduced by the 42nd Amendment in 1976.
In Kesavananda Bharati v. State of Kerala (1973), the Supreme Court held that Parliament can amend the Constitution but cannot alter its basic structure. This doctrine was later reinforced in the Minerva Mills case, but it was first articulated in Kesavananda Bharati.
Qutb-ud-din Aibak established the Slave Dynasty in 1206 after the death of Muhammad Ghori, and he ruled until 1210. Iltutmish, Balban, and Razia Sultana were later rulers of the same dynasty.
The Treaty of Versailles was signed on 28 June 1919 between Germany and the Allied Powers, officially ending World War I. The other years are incorrect: the war ended in 1918 with the armistice, but the treaty was signed in 1919.
The ampere (A) is the SI base unit of electric current, defined as the flow of one coulomb per second. Volt measures potential difference, ohm measures resistance, and watt measures power.
Baking soda is sodium bicarbonate (NaHCO₃), a mild alkaline compound used in cooking and as an antacid. Sodium carbonate is washing soda, sodium chloride is common salt, and sodium hydroxide is caustic soda.
The Green Revolution in India, which began in the late 1960s, led to a significant increase in wheat production, especially in Punjab and Haryana, due to the adoption of high-yielding varieties and modern inputs. While rice also benefited, wheat saw the most dramatic gains.
The liver is the largest gland in the human body, weighing about 1.5 kg in adults, and performs many vital functions including detoxification and bile production. The pancreas, thyroid, and salivary glands are smaller.
Point Nemo is the point on the ocean farthest from any land, situated in the South Pacific Ocean. It is used as a spacecraft cemetery due to its remoteness.
The Bhoodan Movement was initiated by Vinoba Bhave in 1951, who walked across India persuading landowners to donate land to the landless. It was a voluntary land reform movement and later led to the Gramdan movement.
Simple interest is principal × rate × time ÷ 100, so SI = 12000 × 8 × 3 ÷ 100 = ₹2,880. The amount repayable is principal plus interest, 12000 + 2880 = ₹14,880. Adding interest to principal is essential because the question asks for the total amount, not the interest alone.
A 20% discount reduces the marked price by one-fifth: 2500 × 20 ÷ 100 = ₹500. Subtracting the discount from the marked price gives 2500 − 500 = ₹2,000. The selling price is always computed on the marked price, never on the cost price.
Total age of the 10 students is 10 × 15 = 150 years. With the teacher, the total for 11 people is 11 × 17 = 187 years. The teacher's age is the difference, 187 − 150 = 37 years.
Crossing a pole covers the train's own length, so speed = 180 ÷ 12 = 15 m/s. Converting to km/h means multiplying by 18/5, giving 15 × 18 ÷ 5 = 54 km/h. The 18/5 factor converts metres per second into kilometres per hour.
Multiply the significant digits: 4 × 4 × 4 = 64. The decimal places total 1 + 2 + 3 = 6, so the result is 0.000064. Counting decimal places is the reliable shortcut for multiplying decimals.
In one hour the pipes fill 1/6 and 1/12 of the tank, giving a combined rate of 3/12 = 1/4. The reciprocal of that rate is the time taken, so together they need 4 hours. Adding rates and then inverting is the standard method for combined work.
45% of 320 is 0.45 × 320 = 144, and 25% of 480 is 0.25 × 480 = 120. Adding the two gives 144 + 120 = 264. Convert each percentage to a decimal before multiplying to avoid errors.
The word ACIO has four distinct letters, with no repetition. The number of arrangements is 4! = 4 × 3 × 2 × 1 = 24. When all letters differ, the answer is simply the factorial of the letter count.
Profit is 920 − 800 = ₹120. Profit percentage is profit divided by cost price, multiplied by 100: 120 ÷ 800 × 100 = 15%. Profit percentage is always calculated on the cost price.
Doubling means the interest earned in 8 years equals the principal. To become four times, the interest must equal three times the principal, which takes 3 × 8 = 24 years. Simple interest grows linearly with time, so each extra principal-equivalent takes 8 years.
