Past Questions — 2025
The Mizo musical instrument Tumphit produced different notes.
A)
Three
B)
Four
C)
Five
D)
Six
The Tumphit is a traditional Mizo musical instrument, specifically a type of bamboo flute. Unlike simple flutes that may produce only a few tones, the Tumphit is constructed with specific finger holes that allow the performer to produce four distinct notes. This characteristic distinguishes it from other indigenous wind instruments in Mizo culture. Therefore, option (b) is the correct answer.
Which one of the following is correct pair?
A)
Tumchhingi leh Raldawna
B)
Chawngvungi leh Hrangchhuana
C)
Chawngmawii leh Zawlpala
D)
Lasiri leh Neihlala
This question tests knowledge of famous legendary love stories in Mizo folklore.
1. **Chawngmawii and Zawlpala (Option c):** This is one of the most celebrated and authentic tragic love stories in Mizo heritage. Zawlpala was a brave youth and Chawngmawii was a beautiful woman; their love is a cornerstone of Mizo oral tradition and folk songs. This pair is correct.
2. **Tumchhingi and Raldawna (Option a):** This is an incorrect pairing. While these names appear in Mizo folklore, they are not the primary legendary couple associated with each other in the context of the most famous folk tales.
3. **Chawngvungi and Hrangchhuana (Option b):** This is an incorrect pairing. Hrangchhuana is a legendary figure known for his strength and bravery, but he is not paired with Chawngvungi in the standard folklore canon.
4. **Lasiri and Neihlala (Option d):** This is an incorrect pairing.
Therefore, the only historically and culturally accurate pair among the options provided is Chawngmawii and Zawlpala.

Arrange the following letters of each group to make a meaningful word and then find the odd one out.
A)
GHIET
B)
VEENS
C)
ORFU
D)
VIDEID
Step 1: Unscramble the letters of each group to form meaningful words:
- GHIET becomes EIGHT
- VEENS becomes SEVEN
- ORFU becomes FOUR
- VIDEID becomes DIVIDE
Step 2: Analyze the resulting words to find the common theme:
- EIGHT, SEVEN, and FOUR are all number words (cardinal numbers).
- DIVIDE is a mathematical operation.
Step 3: Identify the odd one out:
Since three of the words are numbers and one is an operation, 'DIVIDE' (derived from VIDEID) is the odd one out.
Which one of the following is associated with Lallula?
A)
Khawnglung run
B)
Khuangleng run
C)
Chhim leh hmar indo
D)
Thlanrawn rawt
Lallula was a powerful Mizo chief known for his ambition and military strength. He is historically associated with the 'Khuangleng run' (the blocking of the Khuangleng pass). Lallula attempted to establish a strategic blockade or 'run' at Khuangleng to control movement and assert dominance over neighboring clans and territories.
Analysis of other options:
- Khawnglung run: Not specifically associated with Lallula's primary historical legacy.
- Chhim leh hmar indo: This refers to the general conflicts between the Southern and Northern Mizo groups/clans, which is a broader historical phenomenon rather than a specific act associated solely with Lallula.
- Thlanrawn rawt: This refers to a different historical event/custom not linked to Lallula's strategic military actions.
The State Flower of Mizoram is -
A)
Rhynchostylis Retusa
B)
Red Vanda
C)
Aerides Odorata
D)
Lilium Mackliniae
The State Flower of Mizoram is the Red Vanda (Vanda scented). It is a species of orchid known for its vibrant red color and fragrance, reflecting the rich biodiversity of the state's hilly terrain.
Analysis of other options:
- Rhynchostylis Retusa: This is the state flower of some other regions/species but not Mizoram.
- Aerides Odorata: While common in Southeast Asia, it is not the official state flower of Mizoram.
- Lilium Mackliniae: This is a species of lily found in the Himalayas, but it is not the state flower of Mizoram.
The Union Territory of Mizoram was inaugurated by -
A)
Rajiv Gandhi
B)
Indira Gandhi
C)
PV Narasimha Rao
D)
Morarji Desai
The transition of Mizoram from a district of Assam to a Union Territory occurred following the Mizo Peace Accord of 1986, but the administrative shift began earlier. Mizoram was officially inaugurated as a Union Territory on January 21, 1987, but the process of its creation as a UT was initiated and the decision was finalized during the tenure of Prime Minister Indira Gandhi. Specifically, the Mizoram (Union Territory) Act was passed in 1986, but the political groundwork and the initial elevation to UT status (separating it from Assam) were driven by the administration of Indira Gandhi. While the final statehood was achieved in 1987 under Rajiv Gandhi, the specific act of establishing it as a Union Territory is historically attributed to the era of Indira Gandhi's leadership and the subsequent implementation of the peace process she initiated. Note: In many competitive exams for Mizo history, Indira Gandhi is credited with the pivotal shift toward the UT status that ended the insurgency.
The ambient National Air Quality standard in respect of noise [Limits in dB(A) Leq] for a residential area is -
A)
55 daytime and 45 night time
B)
50 daytime and 40 night time
C)
60 daytime and 50 night time
D)
65 daytime and 55 night time
The Noise Pollution (Regulation and Control) Rules, 2000, established by the Central Pollution Control Board (CPCB) in India, define the ambient air quality standards for noise based on the zoning of the area. For a 'Residential Area', the permissible noise limits are set at 55 dB(A) Leq for the daytime period (6:00 AM to 10:00 PM) and 45 dB(A) Leq for the nighttime period (10:00 PM to 6:00 AM).
Breakdown of other zones for context:
- Industrial Area: 75 dB (Day) / 70 dB (Night)
- Commercial Area: 65 dB (Day) / 55 dB (Night)
- Silence Zone: 50 dB (Day) / 40 dB (Night)
Therefore, option (a) is the correct standard for residential areas.
The Indian biopharma company to develop the first rH-insulin using a Pichia pastoris yeast expression system in the world is-
A)
Bharat Biotech
B)
Novartis
C)
Biocon
D)
Dr Reddy’s Lab
Biocon, an Indian biopharmaceutical company, achieved a global milestone by developing recombinant human insulin (rH-insulin) using the Pichia pastoris yeast expression system. Traditionally, insulin was produced using E. coli or S. cerevisiae; however, Biocon's use of Pichia pastoris allowed for more efficient secretion and folding of the protein, reducing the complexity of the purification process. This innovation positioned Biocon as a leader in the global biosimilars market.
Why other options are incorrect:
- Bharat Biotech: Primarily known for vaccine development (e.g., Covaxin).
- Novartis: A Swiss multinational pharmaceutical company, not an Indian biopharma company.
- Dr Reddy's Lab: While a major Indian pharmaceutical company, they focus more on generics and APIs rather than the pioneering development of the Pichia pastoris insulin expression system.
Sibuta Lung is situated at the outskirt of -
A)
Maubuang village
B)
Muallungthu village
C)
Samlukhai village
D)
Tachhip village
Sibuta Lung is a significant megalithic site located in Mizoram. It is situated on the outskirts of Tachhip village. The site is known for its large standing stones (menhirs) and is of great archaeological and historical importance for understanding the prehistoric and early historic settlements in the region. Options a, b, and c refer to other villages in Mizoram that are not associated with the Sibuta Lung megalithic site.
A cave found in Phawngpui tlang was -
A)
Tialpa puk
B)
Sur puk
C)
Tialpari puk
D)
Pukzing
Phawngpui, also known as the Blue Mountain, is the highest peak in Mizoram. It is renowned for its biodiversity and unique geological formations. Among the various caves and natural landmarks associated with this mountain, 'Tialpari puk' is the specific cave found in the Phawngpui tlang region. The other options listed (Tialpa puk, Sur puk, and Pukzing) are not the recognized names of the cave located specifically on Phawngpui tlang in the context of Mizoram's geographical and cultural records.
Find the word which holds the same relation with the third word as there in between the first two words. Oxygen : Burn :: Carbon dioxide : ?
A)
Isolate
B)
Foam
C)
Extinguishes
D)
Explode
This is an analogy question based on the chemical properties of gases.
1. **Analyze the first pair:** Oxygen : Burn. Oxygen is a gas that supports combustion; it is necessary for a fire to burn. Therefore, the relationship is [Gas] : [Effect/Action it supports].
2. **Analyze the second pair:** Carbon dioxide : ?. Carbon dioxide is a gas that does not support combustion and is commonly used in fire extinguishers to displace oxygen and put out fires. Therefore, the relationship must be [Gas] : [Effect/Action it causes].
3. **Evaluate Options:**
- (a) Isolate: Not a chemical property of CO2 in relation to fire.
- (b) Foam: While some extinguishers use foam, CO2 itself is a gas, not foam.
- (c) Extinguishes: This is the direct opposite of 'burn'. Since Oxygen supports burning, Carbon dioxide extinguishes it.
- (d) Explode: Carbon dioxide is stable and does not cause explosions; it is actually used to prevent them in some contexts.
Thus, the correct word to complete the analogy is 'Extinguishes'.
Choose the number which is different from others.
A)
144
B)
216
C)
343
D)
125
To find the number that is different from the others, we examine the mathematical properties of each option:
1. 144: This is a perfect square (12^2 = 144). It is not a perfect cube.
2. 216: This is a perfect cube (6^3 = 216).
3. 343: This is a perfect cube (7^3 = 343).
4. 125: This is a perfect cube (5^3 = 125).
Comparing the options, 216, 343, and 125 are all perfect cubes, whereas 144 is a perfect square. Therefore, 144 is the odd one out.
The new snake species discovered in Mizoram in 2024 by researchers at the Mizoram University is-
A)
Sinomicrurus gorei
B)
Ahaetulla prasine
C)
Python bivittatus
D)
Smithophis mizoramensis
In 2024, researchers from Mizoram University discovered and described a new species of snake endemic to the state of Mizoram. The species was named 'Smithophis mizoramensis'. This discovery is significant as it adds to the biodiversity records of the Indo-Burma hotspot.
Analysis of other options:
- Sinomicrurus gorei: This is a species of coral snake found in other regions, not the new 2024 discovery from Mizoram University.
- Ahaetulla prasina: This is the common Green Vine Snake, widely distributed across Asia.
- Python bivittatus: This is the Burmese Python, a well-known large snake species found across Southeast Asia.
Therefore, option (d) is the only correct answer based on recent herpetological research conducted by Mizoram University.
The first Indian to take over as Superintendent of Lushai Hills was -
A)
S.N.Barkataki
B)
Brojo Nath Saha
C)
GN Bardoloi
D)
Rup Nath Brahma
The administration of the Lushai Hills (now Mizoram) was historically managed by British officers. However, as part of the process of Indianization of the civil services and the transition toward independence, Indian officers began to take over administrative roles. S.N. Barkataki was the first Indian to be appointed as the Superintendent of the Lushai Hills. The Superintendent was the chief administrative head of the district during the colonial and transitional period before the region evolved into a Union Territory and eventually a state. The other options listed (Brojo Nath Saha, GN Bardoloi, and Rup Nath Brahma) were prominent figures in the politics and administration of Northeast India (particularly Assam), but they did not serve as the first Indian Superintendent of the Lushai Hills.
In ‘hnuaipui’ sacrifice,
A)
a full grown female pig was killed
B)
a young pig was killed
C)
mithun was killed
D)
a full grown hen was killed
In traditional Mizo culture and ancestral belief systems, 'Hnuaipui' refers to a specific type of sacrifice or ritual offering. According to Mizo customary practices and ethnographic records regarding traditional rituals, the 'hnuaipui' sacrifice specifically required the slaughter of a full-grown female pig. This ritual was often associated with seeking protection, healing, or appeasing spirits to ensure the well-being of the community or an individual. Options b, c, and d are incorrect because while mithuns (c) were used in higher-status feasts (Kut or feasts of merit) and hens (d) were used in smaller rituals, the specific requirement for 'hnuaipui' was a mature female pig.
The famous East- West War called ‘Chhak leh Thlang Indo’ was fought between -
A)
Vanhnuailiana vs Thawmvunga
B)
Lallianvunga vs Lalpuithanga
C)
Vutaand Manga vs Lalsavunga
D)
Rolura vs Vuta
The 'Chhak leh Thlang Indo' (East-West War) is a significant conflict in Mizo history. It was a power struggle for supremacy among the Mizo chiefs. The war was fought between the forces of Vanhnuailiana (representing the 'West' or Thlang) and Thawmvunga (representing the 'East' or Chhak). This conflict highlighted the fragmented nature of the Mizo chiefdoms before the British annexation. Options b, c, and d list other Mizo chiefs or combinations that were not the primary combatants of this specific historical event.
In Mizo folktales, a well-known magical object called ‘Bahhnukte’ is found in -
A)
Rairahtea thawnthu
B)
Chhura leh Naa thawnthu
C)
Nuchhimi thawnthu
D)
Sichangneii thawnthu
In Mizo folklore, 'Bahhnukte' refers to magical objects or 'magic bags/pouches' that possess supernatural powers. These are central to the story of 'Rairahtea', a character known for his wit and the use of magical items to outsmart others or overcome obstacles.
- Option (a) Rairahtea thawnthu: Correct. The plot revolves around the acquisition and use of these magical objects.
- Option (b) Chhura leh Naa thawnthu: This is a fable involving a clever man (Chhura) and a tiger (Naa), focusing on wit and trickery rather than magical objects like Bahhnukte.
- Option (c) Nuchhimi thawnthu: This is a tragic folk tale about a girl and her devotion/suffering, not centered on magical pouches.
- Option (d) Sichangneii thawnthu: This is another traditional tale, but it does not feature the 'Bahhnukte' as a primary plot device.
The most abundant Greenhouse Gas in the atmosphere is -
A)
Methane
B)
Carbon Dioxide
C)
Water Vapour
D)
Nitrous Oxide
To determine the most abundant greenhouse gas (GHG), we must distinguish between 'natural' abundance and 'anthropogenic' (human-caused) contribution.
1. **Water Vapour (H2O):** This is the most abundant greenhouse gas in the Earth's atmosphere. It acts as a powerful feedback mechanism; as the atmosphere warms, it holds more water vapour, which in turn traps more heat. Its concentration varies significantly by location and temperature, but globally, it contributes the most to the natural greenhouse effect.
2. **Carbon Dioxide (CO2):** While CO2 is the most significant anthropogenic (human-driven) greenhouse gas and is often the primary focus of climate change discussions due to its long atmospheric lifetime, it is less abundant than water vapour.
3. **Methane (CH4) and Nitrous Oxide (N2O):** These gases are much more potent per molecule than CO2 or H2O in terms of Global Warming Potential (GWP), but they exist in much smaller concentrations (parts per billion or low parts per million).
Therefore, in terms of sheer volume and abundance in the atmosphere, water vapour is the correct answer.
The next number in the sequence will be? 1, 3, 9, 15, 25, 35, 49, ....
A)
61
B)
63
C)
65
D)
81
To find the next number in the sequence 1, 3, 9, 15, 25, 35, 49, ..., we analyze the pattern of the numbers. The sequence is composed of two alternating patterns based on the position of the term:
1. Odd-positioned terms (1st, 3rd, 5th, 7th): 1, 9, 25, 49. These are the squares of consecutive odd numbers: 1², 3², 5², 7².
2. Even-positioned terms (2nd, 4th, 6th): 3, 15, 35. These follow the pattern (n² - 1) where n is an even number: 2²-1=3, 4²-1=15, 6²-1=35.
The next number in the sequence is the 8th term (an even position). Following the pattern for even-positioned terms, the next even number after 6 is 8. Therefore, the calculation is: 8² - 1 = 64 - 1 = 63.
Verification of options:
- a. 61: Incorrect.
- b. 63: Correct (8² - 1).
- c. 65: Incorrect.
- d. 81: This would be the 9th term (9²), not the 8th.
The series of supercomputers designed and assembled by the Centre for Development of Advanced Computing (C-DAC) in Pune, India is -

C)
Arunika
D)
Mihir
The Centre for Development of Advanced Computing (C-DAC), headquartered in Pune, was established in 1988 with the primary objective of designing and developing supercomputers for India. The resulting series of supercomputers is named 'PARAM' (which stands for 'Parallel'). The first supercomputer in this series, PARAM 8000, was launched in 1991. Since then, C-DAC has developed numerous iterations and advanced versions such as PARAM Brahma, PARAM Yuva, and PARAM Siddhi. Options b, c, and d (Arka, Arunika, Mihir) are not recognized series of supercomputers developed by C-DAC.
Which one of the following category is not included in the National Air Quality Index?
A)
Very poor
B)
Severe
C)
Moderately polluted
D)
Highly polluted
The National Air Quality Index (AQI) in India is a tool used to communicate the air quality status to the public. It categorizes air quality into six distinct levels based on the concentration of pollutants (PM2.5, PM10, NO2, SO2, CO, and O3). The six categories are: 1. Good (0-50), 2. Satisfactory (51-100), 3. Moderate (101-200), 4. Poor (201-300), 5. Very Poor (301-400), and 6. Severe (401-500).
Analyzing the options:
- Option (a) 'Very poor' is a valid category.
- Option (b) 'Severe' is a valid category.
- Option (c) 'Moderately polluted' refers to the 'Moderate' category used in the index.
- Option (d) 'Highly polluted' is not a terminology used in the official National AQI classification. While 'Poor' and 'Very Poor' exist, 'Highly polluted' is not a specific category label.
The first recipient of the Padma Shri Award among the women from Mizoram was -
A)
Khawlhkungi
B)
Nuchhungi Renthlei
C)
Buangi Sailo
D)
Lalsangzuali Sailo
Nuchhungi Renthlei was the first woman from Mizoram to be honored with the Padma Shri award. She was recognized for her exceptional contributions to social work and the upliftment of the community in Mizoram. While other women from the state have received prestigious awards for literature, arts, or social service in later years, Nuchhungi Renthlei holds the distinction of being the first female recipient of this specific civilian honor from the state.
It is a network that is constructed by using public wires/network usually the internet to connect to a private network -
A)
VPN
B)
WAN
C)
LAN
D)
MAN
The question describes a Virtual Private Network (VPN). A VPN creates a secure, encrypted 'tunnel' over a public network (typically the internet) to allow users to access a private network as if they were directly connected to it.
Here is why the other options are incorrect:
- b. WAN (Wide Area Network): This is a general category of network that covers a large geographical area. While the internet is the largest WAN, a WAN itself is not specifically defined as a tool to connect to a private network via public wires.
- c. LAN (Local Area Network): This is a network restricted to a small area, like a single building or home, and typically uses private cabling rather than public wires.
- d. MAN (Metropolitan Area Network): This is a network that connects users within a geographic area larger than a LAN but smaller than a WAN (e.g., a city). It does not specifically refer to the mechanism of using public networks to access private ones.
Choose the odd one out from the numbers given
A)
523
B)
121
C)
324
D)
729
To find the odd one out, we examine the mathematical properties of each number provided in the options:
1. **121**: This is a perfect square ($11^2 = 121$).
2. **324**: This is a perfect square ($18^2 = 324$).
3. **729**: This is both a perfect square ($27^2 = 729$) and a perfect cube ($9^3 = 729$).
4. **523**: This number is not a perfect square or a perfect cube. In fact, 523 is a prime number.
Since options b, c, and d are all perfect squares, while option a is not, 523 is the odd one out.
