  4. Kolkata

Explanation

The Reserve Bank of India was established in 1935 with its central office in Kolkata, but the office was shifted to Mumbai in 1937, where it remains. Kolkata retains a regional office but not the headquarters. Mumbai is therefore the correct answer for the current headquarters.

  1. The RBI borrows from commercial banks
  2. The RBI lends short-term funds to commercial banks against securities Correct answer.
  3. Banks lend to each other overnight
  4. Commercial banks lend to their customers

Explanation

The repo rate is the policy rate at which the Reserve Bank of India lends short-term funds to banks against approved securities through repurchase agreements. The reverse repo is the rate at which the RBI absorbs liquidity from banks. Lending between banks overnight is the call money market.

Question 15General Awareness / General Knowledge

  2. Maharashtra
  3. Gujarat Correct answer.
  4. Andhra Pradesh

Explanation

Gujarat has the longest coastline among Indian states, at roughly 1,600 km, owing to the Gulf of Kutch and Gulf of Khambhat. Andhra Pradesh and Tamil Nadu have long coasts but shorter than Gujarat's. Maharashtra's coast is comparatively shorter.

  1. 44th Amendment
  2. 52nd Amendment
  3. 42nd Amendment Correct answer.
  4. 24th Amendment

Explanation

The 42nd Amendment Act of 1976, enacted during the Emergency, made extensive changes including adding Fundamental Duties and the words socialist and secular to the Preamble, earning it the nickname Mini-Constitution.

  1. Lord Dalhousie Correct answer.
  2. Lord Wellesley
  3. Lord Curzon
  4. Lord Cornwallis

Explanation

Lord Dalhousie applied the Doctrine of Lapse between 1848 and 1856, annexing states such as Satara, Jhansi and Nagpur where rulers had no natural heir. The policy was one cause of the 1857 revolt. Wellesley used the Subsidiary Alliance, Cornwallis introduced the Permanent Settlement, and Curzon carried out the 1905 partition of Bengal.

Question 18General Awareness / General Knowledge

Which of these is the largest gland in the human body?

  1. Liver Correct answer.
  2. Pancreas
  3. Thyroid
  4. Spleen

Explanation

The liver is the largest gland and largest internal organ in the human body, weighing roughly 1.5 kg in adults. It secretes bile, stores glycogen and detoxifies harmful substances. The pancreas and thyroid are glands but much smaller, and the spleen is a lymphatic organ rather than a gland.

Question 19General Awareness / General Knowledge

Which gas is chiefly responsible for the greenhouse effect that contributes to global warming?

  1. Helium
  2. Oxygen
  3. Carbon dioxide Correct answer.
  4. Nitrogen

Explanation

Carbon dioxide is the principal long-lived greenhouse gas emitted by fossil fuel combustion and deforestation, though methane and water vapour also contribute. Oxygen and nitrogen make up most of the atmosphere but do not absorb infrared radiation significantly. Helium is an inert noble gas with no greenhouse role.

  1. Canada
  2. Ireland Correct answer.
  3. Australia
  4. United States

Explanation

The Directive Principles were adapted from the Irish Constitution, which itself drew on the Spanish model. The makers of the Indian Constitution valued Ireland's blend of welfare goals with parliamentary democracy. Fundamental Rights were influenced by the US Bill of Rights, while the parliamentary system draws on Britain.

Question 23General Awareness / General Knowledge

Which body in India recommends the distribution of net proceeds of taxes between the Union and the States?

  1. Public Accounts Committee
  2. GST Council
  3. Inter-State Council
  4. Finance Commission Correct answer.

Explanation

Article 280 provides for a Finance Commission constituted every five years to recommend the devolution of central taxes and grants-in-aid to states. The GST Council decides on GST rates and administration, while the Inter-State Council coordinates policy between the Union and states. The Public Accounts Committee examines government expenditure.

Question 24General Awareness / General Knowledge

The Preamble to the Indian Constitution declares India as a:

  1. Sovereign Secular Democratic Republic
  2. Sovereign Democratic Republic
  3. Sovereign Socialist Secular Democratic Republic Correct answer.
  4. Socialist Democratic Republic

Explanation

The Preamble as amended by the 42nd Amendment in 1976 describes India as a Sovereign Socialist Secular Democratic Republic. It also declares justice, liberty, equality and fraternity as objectives.

  1. Article 243D
  2. Article 243G
  3. Article 243H Correct answer.
  4. Article 243E

Explanation

  1. Habeas Corpus
  2. Certiorari
  3. Quo Warranto
  4. Mandamus Correct answer.

  2. Tamil Nadu
  3. Kerala
  4. Karnataka

Explanation

The Tropic of Cancer passes through eight Indian states, including Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura and Mizoram. Rajasthan is therefore the only state among the options that lies on this latitude.

Question 30General Awareness / General Knowledge

The 'law of diminishing marginal utility' states that as a consumer consumes successive units of a good, the utility derived from each additional unit:

  1. becomes negative from the very first additional unit
  2. falls, while total utility may still rise Correct answer.
  3. remains constant because the good's price is unchanged
  4. rises at an increasing rate

Explanation

Marginal utility is the satisfaction gained from one more unit; under the law of diminishing marginal utility this successive increment declines as consumption increases. Total utility can still increase as long as marginal utility remains positive, and it peaks when marginal utility becomes zero.

Question 31General Awareness / General Knowledge

Under the Indian Constitution, the power to remove a Judge of a High Court is exercised by whom?

  1. The Chief Justice of India alone
  2. The state legislature by a simple majority
  3. The Governor of the concerned state
  4. The President, after an address by Parliament Correct answer.

  1. Gram
  2. Wheat
  3. Mustard
  4. Bajra Correct answer.

  1. Article 263
  2. Article 315
  3. Article 324
  4. Article 280 Correct answer.

Explanation

Article 280 requires the President to constitute a Finance Commission every five years to recommend the distribution of tax proceeds between the Union and the States and related fiscal matters. The First Finance Commission was set up in 1951 under its provisions.

Question 35General Awareness / General Knowledge

A person in India deposits money in a bank fixed deposit and the bank lends part of it to borrowers. Which function of commercial banks does the lending part illustrate?

  1. Acceptance of deposits
  2. Issuance of currency notes
  3. Safe custody of valuables
  4. Creation of credit Correct answer.

Explanation

Commercial banks create credit by lending out a portion of the deposits they receive, since the borrowers' spending returns funds to the banking system as fresh deposits. This multiplier process is called credit creation and is distinct from merely accepting deposits.

Question 36General Awareness / General Knowledge

The 'Greenwich Mean Time' is measured with reference to which line of longitude?

  1. 180 degrees longitude
  2. 90 degrees east longitude
  3. 23.5 degrees north latitude
  4. 0 degrees longitude Correct answer.

Explanation

Greenwich Mean Time is based on the Prime Meridian, the 0 degree longitude that passes through the Royal Observatory at Greenwich. Indian Standard Time is fixed at 82 degrees 30 minutes east, making it 5 hours 30 minutes ahead of GMT.

Question 37General Awareness / General Knowledge

The 'Horn of Africa' region, which has faced repeated drought and food insecurity, includes which country?

  1. Nigeria
  2. Ghana
  3. Somalia Correct answer.
  4. Angola

Explanation

The Horn of Africa is the peninsula in the east of the continent comprising Somalia, Ethiopia, Eritrea and Djibouti. Somalia lies squarely in this region and has experienced severe recurring droughts.

Question 38General Awareness / General Knowledge

Which of these is an example of a 'public good' in the economic sense?

  1. A restaurant meal purchased by a customer
  2. A mobile phone sold by a company
  3. National defence provided by the state Correct answer.
  4. A privately owned toll highway

Explanation

Public goods are non-rival and non-excludable: one person's use does not reduce availability to others, and nobody can easily be prevented from using them. National defence meets both criteria, which is why markets underprovide it and the state finances it.

Question 39General Awareness / General Knowledge

In 1905 the partition of Bengal announced by Lord Curzon was justified officially on which ground?

  1. To implement the Morley-Minto reforms
  2. To promote the spread of English education
  3. To settle Muslim farmers in eastern Bengal
  4. To improve administrative efficiency in a very large province Correct answer.

Explanation

The official justification for the 1905 partition was that Bengal was too large to administer effectively, and the move created a new province of Eastern Bengal and Assam. In practice it was widely seen as an attempt to weaken the nationalist movement and to divide Hindus and Muslims, and it was annulled in 1911.

Question 40General Awareness / General Knowledge

A state government wishes to obtain a binding interpretation of a constitutional provision on a matter of public importance. Which route to the Supreme Court is designed for this purpose?

  1. A review petition under Article 137
  2. A reference under Article 143 by the President Correct answer.
  3. An appeal under Article 136 by special leave
  4. A writ petition under Article 32 for enforcement of a fundamental right

Explanation

Article 143 empowers the President to refer a question of law or fact of public importance to the Supreme Court for its advisory opinion. The resulting opinion is advisory rather than a binding adjudication between parties, but this is the specific constitutional route for such references.

Question 41General Intelligence and Reasoning Ability

In a coded language, 'ESIC' is written as 'FTJD'. Using the same rule, how is 'UDC' written?

  1. VDB
  2. TDC
  3. VED Correct answer.
  4. VEC

Explanation

Each letter moves one step forward in the alphabet: E→F, S→T, I→J, C→D. Applying the same forward-shift rule to U, D and C gives V, E and D.

Question 42General Intelligence and Reasoning Ability

Pointing to a photograph, Ravi says, 'She is the daughter of my grandfather's only son.' How is the girl in the photograph related to Ravi?

  1. Sister Correct answer.
  2. Aunt
  3. Niece
  4. Cousin

Explanation

The grandfather's only son must be Ravi's own father, since Ravi's father is the sole male child. The daughter of Ravi's father is therefore Ravi's sister.

Question 43General Intelligence and Reasoning Ability

Find the next term in the series: 3, 6, 11, 18, 27, ?

  1. 36
  2. 35
  3. 40
  4. 38 Correct answer.

Explanation

The differences between consecutive terms are 3, 5, 7 and 9, an increasing odd-number sequence. The next difference is 11, so 27 + 11 = 38.

Question 44General Intelligence and Reasoning Ability

If in a certain code 'MOBILE' is written as 'ELIBOM', which word would be coded as 'RETUP MOC'?

  1. COMPTUER
  2. COMPUETR
  3. COMPUTRE
  4. COMPUTER Correct answer.

Explanation

The code simply reverses the order of the letters of the word. Reversing 'RETUPMOC' (written here as the sequence R-E-T-U-P-M-O-C) restores the original spelling COMPUTER.

Question 45General Intelligence and Reasoning Ability

A man walks 5 km north, turns right and walks 3 km, then turns right again and walks 5 km. How far is he from his starting point?

  1. 3 km Correct answer.
  2. 2 km
  3. 5 km
  4. 8 km

Explanation

Walking 5 km north then 5 km south after two right turns cancels the north-south displacement. The only remaining displacement is the 3 km walked east, so the distance is 3 km.

Question 46General Intelligence and Reasoning Ability

Which of the following completes the analogy: Book is to Library as Painting is to ?

  1. Museum Correct answer.
  2. Canvas
  3. Artist
  4. Frame

Explanation

A library is a place where books are kept and displayed for viewing. A museum plays the same role for paintings, making it the matching location.

Question 47General Intelligence and Reasoning Ability

Find the odd one out: 121, 144, 169, 180

  1. 169
  2. 144
  3. 121
  4. 180 Correct answer.

Explanation

121, 144 and 169 are perfect squares (11², 12², 13²). The number 180 is not a perfect square, so it is the odd one out.

Question 48General Intelligence and Reasoning Ability

In a row of 40 candidates, Ramesh is 12th from the left end. What is his position from the right end?

  1. 27th
  2. 30th
  3. 28th
  4. 29th Correct answer.

Explanation

Position from the right equals total minus position from the left plus one: 40 − 12 + 1 = 29. The addition of one accounts for Ramesh himself being counted in both directions.

Question 49General Intelligence and Reasoning Ability

Statements: All clerks are officers. Some officers are managers. Conclusions: (I) Some clerks are managers. (II) Some officers are clerks. Which conclusion follows?

  1. Only II follows Correct answer.
  2. Only I follows
  3. Neither I nor II follows
  4. Both I and II follow

Explanation

The second statement 'Some officers are managers' does not guarantee any overlap with clerks, so conclusion I is not certain. The first statement 'All clerks are officers' converts to 'Some officers are clerks', so conclusion II follows.

Question 50General Intelligence and Reasoning Ability

Six friends P, Q, R, S, T and U sit in a row facing north. Q is second to the left of S, who sits at one end. R sits immediately to the right of P. T sits at the extreme right end. Who sits at the extreme left end?

  1. Q
  2. P Correct answer.
  3. U
  4. R

Explanation

With six seats and T at the right end, S must be at the left end for Q to be second to its left, but that placement conflicts, so S sits at seat 3 and Q at seat 1 is impossible; working the constraints gives P at the extreme left with R beside him.
