The letters of the name of a fruit are U, A, L, E, N, C, P, T, A, O. If the letters are rearranged correctly, then what is the last letter of the word formed?
A)
N
B)
C
C)
A
D)
E
To find the correct answer, we first need to rearrange the given letters (U, A, L, E, N, C, P, T, A, O) to form the name of a fruit. Rearranging these letters gives the word 'CANTALOUPE'. The last letter of the word 'CANTALOUPE' is 'E'. Therefore, option 'd' is the correct answer. Options 'a', 'b', and 'c' are incorrect because 'N', 'C', and 'A' are not the final letters of the correctly formed fruit name.
With reference to India’s ‘Green Hydrogen Mission’, consider the following statements: 1. Green hydrogen is produced through the electrolysis of water using renewable energy. 2. The mission targets a production capacity of at least 5 MMT (Million Metric Tonne) per annum by 2030. 3. Hydrogen is currently used primarily in the transport sector in India. Which of the statements given above are correct?
A)
1, 2, and 3
B)
2 and 3 only
C)
1 and 3 only
D)
1 and 2 only
Statement 1 is correct: Green hydrogen is produced through the electrolysis of water, where electricity generated from renewable energy sources (like solar or wind) is used to split water into hydrogen and oxygen. Statement 2 is correct: The National Green Hydrogen Mission, launched by the Government of India, explicitly targets building a green hydrogen production capacity of at least 5 MMT (Million Metric Tonne) per annum by 2030. Statement 3 is incorrect: Currently, hydrogen in India is primarily used as a feedstock in industrial sectors such as petroleum refining, ammonia production (fertilizers), and steel manufacturing, rather than the transport sector, which is still in an experimental/pilot phase. Therefore, only statements 1 and 2 are correct.
If APRIL is codded as ZNOEG, the how will you encode AUGUST?
A)
ZDSQNN
B)
ZSDQNN
C)
DQNNZS
D)
DQNZSN
The coding pattern involves subtracting consecutive integers from the position of each letter in the alphabet: -1, -2, -3, -4, -5, and so on.
Applying this to 'APRIL':
- A (1) - 1 = Z (26)
- P (16) - 2 = N (14)
- R (18) - 3 = O (15)
- I (9) - 4 = E (5)
- L (12) - 5 = G (7)
This gives 'ZNOEG'.
Applying the same pattern to 'AUGUST':
- A (1) - 1 = Z (26)
- U (21) - 2 = S (19)
- G (7) - 3 = D (4)
- U (21) - 4 = Q (17)
- S (19) - 5 = N (14)
- T (20) - 6 = N (14)
This gives 'ZSDQNN'.
- Option 'a' is incorrect because the second and third letters ('S' and 'D') are swapped.
- Options 'c' and 'd' are incorrect because they do not start with 'Z' and fail to follow the correct subtraction sequence.
Mizoram was declared as a ‘disturbed area’ under the Assam Disturbed Areas Act 1955 in:
A)
1966
B)
1967
C)
1968
D)
1969
Mizoram (then the Mizo District of Assam) was declared a 'disturbed area' under the Assam Disturbed Areas Act, 1955, in March 1966. This declaration was made immediately following the outbreak of the armed uprising by the Mizo National Front (MNF) on March 1, 1966, to enable the deployment of the military to suppress the rebellion. The other options (1967, 1968, and 1969) are incorrect because the official declaration was enacted in 1966, right at the onset of the insurgency.

D)
Ministry of Commerce and Industry
The India Semiconductor Mission (ISM) is functionally housed as an independent business division within the Digital India Corporation (DIC), which is under the Ministry of Electronics and Information Technology (MeitY). It was established to drive India's strategies for developing a semiconductor and display ecosystem. Option 'a' (NITI Aayog) is a policy think tank, Option 'b' (DST) focuses on general science and technology research, and Option 'd' (Ministry of Commerce and Industry) handles trade and industrial policy, making them incorrect.
India’s first satellite Aryabhata was launched primarily to:
A)
Enable communication services
B)
Monitor weather patterns
C)
Demonstrate indigenous satellite technology
D)
Conduct military reconnaissance
India's first satellite, Aryabhata, was launched on April 19, 1975, primarily to demonstrate indigenous capabilities in satellite technology, including designing, fabricating, and operating a spacecraft in orbit. While it carried scientific instruments for experiments in X-ray astronomy, aeronomy, and solar physics, its main goal was technological demonstration. Option 'a' is incorrect because communication services were established later with the INSAT series. Option 'b' is incorrect as weather monitoring was achieved through later satellites like INSAT and Kalpana-1. Option 'd' is incorrect because Aryabhata had no military reconnaissance capabilities.
A criminal who took refuge to the Chief’s house to escape from the consequences of his evil deeds was known as:
A)
Chemsen Bawi
B)
Tukluh Bawi
C)
Inhrang Bawi
D)
Inpuichhung Bawi
In traditional Mizo society, the 'Bawi' system represented a form of social dependency or servitude. The correct option is 'Chemsen Bawi' (literally meaning 'red/bloody knife slave'), which refers to criminals or murderers who fled to the Chief's house to seek asylum and escape the consequences of their crimes. By entering the Chief's house, they became his lifelong dependents, and the Chief protected them from revenge.
- 'Inpuichhung Bawi' refers to those who entered the Chief's household due to poverty, hunger, or destitution.
- 'Inhrang Bawi' refers to dependents who were permitted by the Chief to live in separate houses of their own.
- 'Tukluh Bawi' refers to enemies or prisoners of war who surrendered to the Chief to save their lives.
What is the main source of energy in solar flares?
A)
Gravitational energy
B)
Magnetic energy
C)
Nuclear energy
D)
Solar tidal energy
The correct option is 'b' (Magnetic energy). Solar flares are sudden, intense explosions on the Sun's surface caused by the rapid release of magnetic energy stored in the solar corona. This occurs through a process called magnetic reconnection, where twisted magnetic field lines snap and realign, releasing vast amounts of energy. Other options are incorrect because: (a) Gravitational energy is responsible for the Sun's structural stability and initial formation, not solar flares; (c) Nuclear energy (fusion) powers the Sun's core but does not directly trigger atmospheric flares; and (d) Solar tidal energy from planetary gravitational pull is negligible and does not cause solar flares.
In a 60-litre solution of sugar and water, there is 15% sugar. How much sugar (in kg/litres) should be added to make the sugar content 25% of the total solution?
A)
8 Litre
B)
10 Litre
C)
12 Litre
D)
20 Litre
To find the amount of sugar to be added, we can set up an equation based on the concentration of sugar.
1. **Calculate initial quantities:**
- Total initial solution = 60 litres
- Initial sugar content = 15% of 60 = 9 litres
- Initial water content = 60 - 9 = 51 litres
2. **Set up the equation for adding sugar:**
- Let the amount of sugar to be added be $x$ litres.
- New sugar quantity = $9 + x$ litres
- New total solution volume = $60 + x$ litres
- We want the new sugar content to be 25% (or 1/4) of the total solution:
$$\frac{9 + x}{60 + x} = \frac{1}{4}$$
$$4(9 + x) = 60 + x$$
$$36 + 4x = 60 + x$$
$$3x = 24$$
$$x = 8\text{ litres}$$
Thus, adding 8 litres of sugar makes the sugar content 25% of the total solution, making option (a) the correct choice.
**Why other options are incorrect:**
- **Option b (10 Litre):** Adding 10 litres of sugar results in a sugar concentration of $(9+10)/(60+10) = 19/70 \approx 27.14\%$, which is not 25%.
- **Option c (12 Litre):** Adding 12 litres of sugar results in a sugar concentration of $(9+12)/(60+12) = 21/72 \approx 29.17\%$, which is not 25%.
- **Option d (20 Litre):** Adding 20 litres of sugar results in a sugar concentration of $(9+20)/(60+20) = 29/80 = 36.25\%$, which is not 25%.
In the context of India’s ‘National Supercomputing Mission’ (NSM), which organization is the lead agency for designing and developing indigenous supercomputers like ‘PARAM Rudra’?
A)

C)
C-DAC (Centre for Development of Advanced Computing)
D)
Defence Research and Development Organisation (DRDO)
Under India's National Supercomputing Mission (NSM), which is jointly steered by the Department of Science and Technology (DST) and the Ministry of Electronics and Information Technology (MeitY), the Centre for Development of Advanced Computing (C-DAC) is the lead agency responsible for designing, developing, and deploying indigenous supercomputers, including the 'PARAM' series like 'PARAM Rudra'.
- Option a (ISRO) is incorrect as it is India's space agency focused on space exploration and satellite technology.
- Option b (NITI Aayog) is incorrect as it is a policy think tank of the Government of India.
- Option d (DRDO) is incorrect as it is dedicated to military and defense-related research and development.
Lalvunga Zai belongs to which category?
A)
Chai hla
B)
Chawngchen zai
C)
Salu lam hla
D)
Hlado
In Mizo traditional literature and folk music, 'Lalvunga Zai' belongs to the category of 'Chawngchen zai'. Chawngchen zai are songs associated with the Chawng festival, and Lalvunga Zai is one of its primary forms. Other options are incorrect because: 'Chai hla' (Option a) are songs sung during the Chapchar Kut festival for the Chai dance; 'Salu lam hla' (Option c) are songs performed to celebrate a successful hunt; and 'Hlado' (Option d) is a chanting song used by hunters to proclaim their victory or success.
Which statement best explains the role of the Indian Council of Medical Research (ICMR) in India’s development?
A)
It runs all government hospitals in India
B)
It conducts and coordinates biomedical research to support public health policies and programmes
C)

The primary objective of the FAME-II (Faster Adoption and Manufacturing of Hybrid and Electric Vehicles) scheme is to encourage the electrification of public and shared transportation (such as electric buses, three-wheelers, and shared four-wheelers) as well as personal two-wheelers through demand incentives. Option b is incorrect because there is no mandate to manufacture 100% of EV batteries in India by 2024. Option c is incorrect as there is no policy mandating all petrol pumps to convert to EV charging points by 2026. Option d is incorrect because the scheme supports the establishment of charging infrastructure but does not provide free electricity to charging stations.
Long term exposure to which of the following element can cause cancer?
A)
Iron
B)
Chlorine
C)
Iodine
D)
Arsenic
Arsenic is a well-documented human carcinogen (classified as Group 1 by the IARC). Long-term exposure to arsenic, most commonly through contaminated drinking water, is strongly linked to an increased risk of developing skin, lung, bladder, kidney, and liver cancers. In contrast, Iron (a) and Iodine (c) are essential nutrients required for normal physiological functions and do not cause cancer under normal exposure. Chlorine (b) is widely used as a disinfectant and, while toxic in high concentrations, is not classified as a primary carcinogen.
Find the wrong number in the given series: 10, 41, 94, 1624, 2516, 3625
A)
94
B)
2516
C)
10
D)
1624
The given series follows a pattern where each term is formed by concatenating the square of $n$ and the square of $(n-1)$, where $n$ represents the position of the term (starting from $n = 1$):
- **1st term ($n=1$):** $1^2$ and $0^2 \rightarrow 1$ and $0 \rightarrow 10$
- **2nd term ($n=2$):** $2^2$ and $1^2 \rightarrow 4$ and $1 \rightarrow 41$
- **3rd term ($n=3$):** $3^2$ and $2^2 \rightarrow 9$ and $4 \rightarrow 94$
- **4th term ($n=4$):** $4^2$ and $3^2 \rightarrow 16$ and $9 \rightarrow 169$ (but the given term is **1624**)
- **5th term ($n=5$):** $5^2$ and $4^2 \rightarrow 25$ and $16 \rightarrow 2516$
- **6th term ($n=6$):** $6^2$ and $5^2 \rightarrow 36$ and $25 \rightarrow 3625$
Since the 4th term should be 169 instead of 1624, **1624** is the wrong number in the series.
**Why other options are incorrect:**
- **a (94):** Fits the pattern perfectly as $3^2$ and $2^2$.
- **b (2516):** Fits the pattern perfectly as $5^2$ and $4^2$.
- **c (10):** Fits the pattern perfectly as $1^2$ and $0^2$.

2. **Mim Kût** is a festival of remembrance for departed souls, celebrated in August/September after the maize (mim) harvest. It typically lasts for one to two days.
3. **Pawl Kût** is a post-harvest festival celebrated in December after the main paddy harvest is gathered, traditionally lasting for a few days to a week.
Since all statements (1, 2, and 3) are factually correct, option 'd' is the correct choice.
Who introduced the practice of burying a deceased person at thlanmual?
A)
Zosaphluia
B)
Zosapthara
C)
Pu Buanga
D)
C.G.G. Helm
The correct option is B (Zosapthara). Rev. Edwin Rowlands, affectionately known to the Mizos as Zosapthara, introduced the practice of burying the deceased in a common village cemetery (thlanmual) in Mizoram. Prior to this, the traditional Mizo custom was to bury the dead near or underneath their houses.
- Option A: Zosaphluia (Rev. D.E. Jones) was the first Welsh Presbyterian missionary to Mizoram but is not credited with introducing the common cemetery system.
- Option C: Pu Buanga (James Herbert Lorrain) was a pioneer missionary famous for creating the Mizo alphabet, dictionary, and translating scriptures.
- Option D: C.G.G. Helm was a British administrator in the Lushai Hills and was not responsible for this socio-religious reform.
With reference to ‘Liquid Nano Urea’, which organization developed the world’s first commercial version of this fertilizer in India?
A)
FCI (Food Corporation of India)
B)
IFFCO (Indian Farmers Fertiliser Cooperative Limited)
C)
(NFL) National Fertilizers Limited
D)
ICAR (Indian Council of Agricultural Research)
The correct option is 'b' because the Indian Farmers Fertiliser Cooperative Limited (IFFCO) developed the world's first commercial Liquid Nano Urea at its Nano Biotechnology Research Centre (NBRC) in Kalol, Gujarat.
- Option 'a' (FCI) is incorrect as the Food Corporation of India is responsible for food security, procurement, and distribution of food grains, not fertilizer development.
- Option 'c' (NFL) is incorrect because while National Fertilizers Limited is a major public sector producer of chemical fertilizers, it did not develop this nano-fertilizer.
- Option 'd' (ICAR) is incorrect as the Indian Council of Agricultural Research is an apex body for coordinating, guiding, and managing research and education in agriculture, but the commercial development of Liquid Nano Urea was specifically done by the cooperative IFFCO.

He is also celebrated as the first Mizo chief to learn to read and write using the Roman script. The other options (Chief Rothangpuia, Chief Lalluauva, and Chief Darmaka) were also prominent Mizo chiefs during the colonial era, but none of them were recipients of the Kaisar-i-Hind medal.
The ‘valley of death’ in India’s innovation ecosystem refers to:
A)
Brain drain of scientists
B)
Failure of startups after IPO
C)
Gap between research output and commercial deployment
D)
Decline in patent quality
The 'valley of death' in the innovation ecosystem refers to the critical gap between early-stage research/proof-of-concept and its successful commercialization or market deployment. Many promising scientific discoveries and technological innovations fail during this transition phase due to a lack of funding, technical scale-up support, and business expertise. Option 'a' (brain drain) refers to human capital flight, option 'b' (failure after IPO) occurs at a much later stage of a company's lifecycle, and option 'd' (decline in patent quality) refers to intellectual property standards, making them incorrect.
On April 17, 1975, _________ led by Brig. T.Sailo became a political entity named ‘People’s Conference’.
A)
Human Rights Committee
B)
Mizo Union
C)
Human Resources Committee
D)
Mizo Democratic Front
On April 17, 1975, the Human Rights Committee, led by Brigadier Thenphunga Sailo, was converted into a political party named the 'People's Conference' (later known as the Mizoram People's Conference). Brig. T. Sailo had initially formed the Human Rights Committee in 1974 to address and protest against human rights violations in Mizoram. Other options are incorrect because: 'Mizo Union' (b) was the first political party in Mizoram founded in 1946; 'Human Resources Committee' (c) is a distractor; and 'Mizo Democratic Front' (d) is a different political entity not associated with the formation of the People's Conference.
What was the Mizo name given to Thomas Herbert Lewin (1839-1916)?
A)
Thangliana
B)
Zochhumi Pa
C)
Hmuihmula
D)
Dari Pa
Thomas Herbert Lewin (1839–1916) was a British military officer and administrator in the Chittagong Hill Tracts and Lushai Hills. He was highly respected by the Mizo people, who affectionately named him 'Thangliana', which translates to 'man of great fame' or 'prestigious one'. The other options, such as 'Zochhumi Pa', 'Hmuihmula', and 'Dari Pa', are incorrect as they do not represent the Mizo name given to Lewin.
