Delhi is the correct answer. The Delhi government approved the Electric Vehicle Policy, 2019 to promote adoption of electric vehicles, reduce air pollution, and build EV charging infrastructure in the capital. The other options are incorrect: Chandigarh is a Union Territory but the policy referred to in the question is specifically Delhi’s 2019 EV policy; Bangalore is a city, not a state/UT; and Kolkata is a city in West Bengal, not a state/UT.
Who among the following discovered Neutron?
A)
Thomson
B)
Rutherford
C)
Chadwick

Bohr
James Chadwick discovered the neutron in 1932, so option c is correct. Rutherford discovered the atomic nucleus, Thomson discovered the electron, and Bohr proposed the atomic model with quantized orbits; none of them discovered the neutron.
A student has to get 40% marks to pass in an examination. Suppose he gets 30 marks and fails by 30 marks, then what are the maximum marks in the examination?
A)
100
B)
120
C)
150
D)
300
He scored 30 marks and failed by 30 marks, so the passing marks are 30 + 30 = 60. Since passing requires 40% of the total marks, we have 40% of total = 60. Therefore, total marks = 60 ÷ 0.4 = 150. So the correct option is c? Wait, check the options: 150 is option c. Hence the correct answer is c. The other options are incorrect because 100, 120, and 300 would give passing marks of 40, 48, and 120 respectively, none of which match the required 60.
What is the currency of United Arab Emirates?
A)
Dinar
B)
Rial
C)
Riyal
D)
Dirham
The currency of the United Arab Emirates (UAE) is the UAE Dirham (AED), so option d is correct. The other options are incorrect because Riyal is used in countries like Saudi Arabia and Qatar, Rial is used in countries such as Iran and Oman, and Dinar is the currency of countries like Kuwait, Bahrain, and Jordan.
A solid cube is 3 cm side, painted on all its faces, is cut up into small cubes of 1 cm side. How many of the small cubes will have exactly two painted faces?
A)
12
B)
8
C)
6
D)
4
A 3 cm cube cut into 1 cm cubes gives a 3×3×3 arrangement. Small cubes with exactly two painted faces lie on the edges, excluding the corner cubes. Each of the 12 edges has (3 − 2) = 1 such cube, so total = 12 × 1 = 12. Hence option (a) is correct.
Why others are incorrect: 8 is the number of corner cubes, and each corner cube has 3 painted faces, not 2. 6 is the number of face-center cubes in a 3×3×3 cube, and each has only 1 painted face. 4 does not match any valid count for cubes with exactly two painted faces in this arrangement.
If day before yesterday was Friday then what will be the third day after the day-after-tomorrow?
A)
Sunday
B)
Saturday
C)
Friday
D)
Thursday
If the day before yesterday was Friday, then yesterday was Saturday and today is Sunday. So the day-after-tomorrow is Tuesday. The third day after Tuesday is Friday. Therefore, the correct option is c (Friday). The other options are incorrect because Saturday is only the first day after Tuesday, Thursday is the second day after Tuesday, and Sunday is not the third day after Tuesday.
Which rank has been achieved by India in the Climate Change Performance Index, 2019?
A)
7
B)
9
C)
11
D)
13
India ranked 9th in the Climate Change Performance Index (CCPI) 2019, so option b is correct. The other options are incorrect because 7th, 11th, and 13th do not match India’s CCPI 2019 ranking.
Peter Handke received the Nobel Prize of 2019 in which field?
A)
Physiology or Medicine
B)
Literature
C)
Peace prize
D)
Economic Science
Peter Handke was awarded the 2019 Nobel Prize in Literature, so option b is correct. The other options are incorrect because the Nobel Prize in Physiology or Medicine is a separate category, the Peace Prize is awarded for peace efforts, and Economic Science refers to the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, not Handke's award.
Mizoram is the ______ State of the Indian Union?
A)
22nd
B)
23rd
C)
24th
D)
25th
Mizoram became the 23rd State of the Indian Union on 20 February 1987, when it was granted statehood under the North Eastern Areas (Reorganisation) Act, 1971. Therefore, option (b) 23rd is correct. The other options are incorrect because Mizoram was not admitted as the 22nd, 24th, or 25th state; those numbers correspond to different states in India’s statehood chronology.
If Pen < Pencil, Pencil < Book and Book > Cap, then which one of the following is always true?
A)
Pen > Cap
B)
Pen < Book
C)
Pencil = Cap
D)
Pencil > Cap
Given Pen < Pencil and Pencil < Book, by transitivity we get Pen < Book. This is always true. Also, Book > Cap only tells us Book is greater than Cap; it does not fix the relation between Pen/Pencil and Cap.
Why others are incorrect:
- a) Pen > Cap: not guaranteed, because Cap could be greater than Pen.
- c) Pencil = Cap: not guaranteed; no equality is given.
- d) Pencil > Cap: not guaranteed; Cap could be greater than or less than Pencil.
In the Citizenship Amendment Act 2019, which of the following religion is not mentioned?
A)
Parsi
B)
Christian
C)
Jain
D)
Sufi
The Citizenship Amendment Act (CAA), 2019 mentions six religions: Hindu, Sikh, Buddhist, Jain, Parsi, and Christian. Therefore, among the given options, Sufi is not mentioned in the Act, making option d correct. The other options are incorrect because Christian, Parsi, and Jain are explicitly included in the CAA 2019 list.
If RAMON is written as 12345 and DINESH as 675849, then HAMAM will be written as
A)
92233
B)
92323
C)
93322
D)
93232
From the examples, each letter is replaced by a fixed digit according to its position in the alphabet mapping used in the question: R=1, A=2, M=3, O=4, N=5 and D=6, I=7, E=8, S=9, H=4? But the key pattern is that the same letter must always get the same digit within the given coding. For HAMAM, the repeated pattern is H A M A M, so the code must have the form _ _ _ _ _. Among the options, only 92323 matches the repetition pattern H-A-M-A-M as 9-2-3-2-3, i.e., the 2nd and 4th digits are the same and the 3rd and 5th digits are the same, exactly as required. Option a (92233) breaks the M repetition, option c (93322) breaks both repeated positions, and option d (93232) does not preserve the A and M repetitions correctly. Therefore, the correct answer is b.
The 2019 Nobel prize in Chemistry has been awarded for discovery in which field?
A)
Biological Clock
B)
Cryo-electron microscopy
C)
Lithium-ion batteries
D)
Phage display of peptides
The 2019 Nobel Prize in Chemistry was awarded for the development of cryo-electron microscopy (cryo-EM), a technique that allows scientists to determine the structures of biomolecules at near-atomic resolution. It was shared by Jacques Dubochet, Joachim Frank, and Richard Henderson. The other options are incorrect because: (a) Biological clock research was recognized in the 2017 Nobel Prize in Physiology or Medicine, not Chemistry; (c) Lithium-ion batteries were awarded the 2019 Nobel Prize in Chemistry, but for John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino—this is actually the correct 2019 Chemistry prize topic, so if the question asks 'discovery in which field' the intended answer is lithium-ion batteries; however, among the given options, the 2019 Chemistry Nobel was for lithium-ion batteries, not cryo-EM; (d) Phage display of peptides was recognized in the 2018 Nobel Prize in Chemistry for George P. Smith and Sir Gregory P. Winter. Therefore, the correct option from the list is c.
Budget of the State/Union mainly refers to:
A)
Policy of Receipts and Expenditure
B)
Fund segregated for priority sector
C)
Proposal of annual Receipts and Expenditure.
D)
Target to be achieved in Government Receipts.
The Budget of a State/Union mainly means the annual financial statement showing the government's proposed receipts and expenditures for the coming financial year. Hence, option (c) is correct because it refers to the proposal of annual receipts and expenditure.
Option (a) is incorrect because a budget is not merely a general policy; it is a concrete annual financial plan. Option (b) is incorrect because a segregated fund for a priority sector is only a specific allocation within the budget, not the budget itself. Option (d) is incorrect because the budget is not just a target for government receipts; it includes both receipts and expenditures.
Oxford Dictionaries has named which word as its 2019 Word of the Year?
A)

Oxford Dictionaries named "climate emergency" as its 2019 Word of the Year. The term saw a sharp rise in usage in 2019, reflecting global concern over climate change and the urgency of the issue. The other options are incorrect because "climate change" is a long-established general term, while "climate anxiety" and "climate denial" were not Oxford's 2019 Word of the Year.
The Mizoram Peace Accord, 1986 was signed on ?
A)
March 30
B)
April 30
C)
May 30
D)
June 30
The Mizoram Peace Accord was signed on 30 April 1986, so option (b) April 30 is correct. The other dates—March 30, May 30, and June 30—do not match the officially recorded signing date of the accord.
Which of the following planet has No Moon?
A)
Venus
B)
Mars
C)
Jupiter
D)
Uranus
Venus is the correct answer because it has no natural satellite (moon). In contrast, Mars has two moons (Phobos and Deimos), Jupiter has many moons, and Uranus also has multiple moons. Therefore, among the given options, only Venus has no moon.
The Union Territory of Mizoram came into being on 21st January, 19__
A)
71
B)
72
C)
73
D)
74
Mizoram became a Union Territory on 21 January 1972, under the North-Eastern Areas (Reorganisation) Act, 1971. Therefore the correct completion is 19__ = 72, which corresponds to option c. The other options are incorrect because 1971 is the year of the Act, not the date of UT formation; 1973 and 1974 are later years and do not match the official establishment date.

The study of Mountains is known as
A)
Orology
B)
Lithology
C)
Acrology
D)
Geology
The study of mountains is called **orology** (from Greek *oros*, meaning mountain). Therefore, option **a** is correct. The other options are incorrect: **geology** is the study of the Earth as a whole, including its materials and processes; **lithology** is the study of rocks and their physical characteristics; and **acrology** is not the standard term for the study of mountains.

A)
TH Lewin
B)
William Williams
C)
JH Lorrain
D)
DE Jones
TH Lewin is regarded as the first European to enter/come to Mizoram (then the Lushai Hills) in the historical record. He visited the area in 1871–72 during the British expedition and is commonly credited as the first to come to Mizoram among the given names. William Williams, D.E. Jones, and J.H. Lorrain came later as missionaries/administrators, so they are not the first.
Which Indian economist has won the 2019 Nobel Economics Prize for study on poverty?
A)
Abhijit Banerjee
B)
Arvind Subramanian
C)
Pranab Bardhan
D)
Srijit Mukherji

If LYJEO is the code for MAMIT, the code for SAIHA is
A)
RYFDV
B)
TBJIB
C)
RZHGZ
D)
RBHIB
From MAMIT → LYJEO, each letter is shifted backward by 1, 2, 3, 4, 5 respectively:
M→L (-1), A→Y (-2), M→J (-3), I→E (-4), T→O (-5).
Apply the same pattern to SAIHA:
S→R (-1), A→Y (-2), I→F (-3), H→D (-4), A→V (-5).
So the code is RYFDV, which is option a.
Why others are incorrect:
- b) TBJIB does not follow the required decreasing backward shifts.
- c) RZHGZ also does not match the -1, -2, -3, -4, -5 pattern.
- d) RBHIB is incorrect for the same reason.
Therefore, the correct option is a.
What is the chemical name of Vinegar?
A)
Tartaric Acid
B)
Malic Acid
C)
Citric Acid
D)
Acetic Acid
Vinegar is an aqueous solution of acetic acid (ethanoic acid), typically produced by fermentation of ethanol. Therefore, the correct option is d. The other options are incorrect because citric acid is found in citrus fruits, tartaric acid is found in tamarind and grapes, and malic acid is found in apples and other fruits; none of these is the main acid in vinegar.
Aluminium Salt used to Stop Bleeding is
A)
Potash Alum
B)
Aluminium Chloride
C)
Nitrous Alum
D)
Sulphur Alum
Potash alum (potassium aluminium sulfate) is commonly used as a styptic/astringent to stop minor bleeding because it constricts tissues and helps clotting at the surface. Aluminium chloride is also an astringent, but in standard exam context the traditional “aluminium salt used to stop bleeding” refers to potash alum. Nitrous alum and sulphur alum are not standard medicinal styptics used for this purpose.
