Question 1 of 30
1. Question
1 pointsConsider the following:
- Cosmology
- Genealogy
- Astronomy
- Grammar
How many of the above subjects were addressed in the ancient Puranas?
Correct
Answer: d
Explanation:
- Puranas helped Hinduism develop from the ancient Vedic faith. In Sanskrit, the word “Purana” literally translates as “to resurrect the old.” Most likely during the third and eleventh centuries AD, the Puranas were written.
- They were written in order to show the populace the veracity of the Vedas. The Puranas impart philosophical and theological principles via well-known folklore and mythological tales.
- The literature of the Puranas is broad and addresses a variety of subjects, including but not limited to:
- Cosmology
- Genealogy/Medicine
- Astronomy
- Goddesses and Gods
- Grammar
- Demigods
- Heroes
- Sages
- Cosmology: The Puranas extensively delve into cosmology, describing the creation, structure, and eventual destruction of the universe according to Hindu mythology. They discuss concepts such as the cyclical nature of time, the different realms of existence, and the role of various deities in cosmic affairs.
- Genealogy: Genealogy is another significant aspect covered in the Puranas. These texts often contain elaborate genealogies of gods, sages, and legendary figures, tracing their lineage through various generations. Genealogical accounts help establish the connections between different characters and lineages in Hindu mythology.
- Astronomy: While the primary focus of the Puranas is not astronomy in the modern scientific sense, they do contain astronomical references. The Puranas include descriptions of celestial bodies, planetary movements, and cosmic events, often within the context of mythological narratives.
- Grammar: Puranas do contain linguistic elements, including rules of Sanskrit grammar and the use of language in narrative storytelling.
- Hence, option (d) is correct.

Question 2 of 30
2. Question
1 pointsWhich of the following was the most commonly addressed subject by ancient Sanskrit poets?
Correct
Answer: c
Explanation:
- The common subjects addressed by old Sanskrit poets were primarily related to human experiences, emotions, and the natural world, rather than subjects like politics, economics, mathematics, or science.
- Politics and administration: While there might be occasional references to political events or economic transactions in Sanskrit poetry, these subjects were not commonly addressed by old Sanskrit poets. The focus of Sanskrit poetry was more on aesthetic and philosophical themes rather than practical matters of governance or finance.
- Mathematics and science: Similar to politics, mathematics and science were not prevalent themes in old Sanskrit poetry. Sanskrit literature did contribute to mathematical and scientific knowledge through texts like the Sulba Sutras, but these were distinct from the poetic tradition.
- Love and nature: This aligns closely with the themes commonly found in Sanskrit poetry. Love, in its various manifestations, including romantic love, divine love, and familial love, was a central theme in many Sanskrit poems. Nature, with its beauty and symbolism, also frequently appeared in Sanskrit poetry, often intertwined with themes of love and spirituality.
- The “Meghaduta” (Cloud Messenger) by Kalidasa is a classic Sanskrit poem that depicts the longing of a separated lover, who sends a message to his beloved through a cloud.
- The “Gita Govinda” by Jayadeva explores the divine love between Lord Krishna and Radha, expressed through poetry and music.
- “Raghuvamsha” and the “Kumarasambhava,” nature is often described in vivid detail, with poetic imagery evoking landscapes, seasons, and natural phenomena.
- The “Shakuntala” by Kalidasa contains beautiful descriptions of forests, rivers, and wildlife, setting the backdrop for the love story between King Dushyanta and Shakuntala.
- Religion and mythology: Religion and mythology were indeed prominent subjects addressed by old Sanskrit poets. Many Sanskrit poems were dedicated to praising and invoking gods and goddesses, recounting their myths, and exploring religious themes such as devotion, karma, and dharma. However, religion and mythology were the themes of bigger/ more elaborate works such as puranas, Vedas and epics like Ramayana and Mahabharata than poems.
- Hence, option (c) is correct.

Question 8 of 30
8. Question
1 pointsConsider the following statements with reference to Poetess Andal:
- She is the only female Alvar.
- Andal composed only two works in Tamil known as Tiruppavai and Nacciyar Tirumoli.
- Andal’s poems solely contain her experiences as a devotee of Lord Krishna.
How many of the above statements are correct?
Correct
Answer: b
Explanation:
- Some of the earliest bhakti movements (c. sixth century) were led by the Alvars (literally, those who are “immersed” in devotion to Vishnu) and Nayanars (literally, leaders who were devotees of Shiva). They travelled from place to place singing hymns in Tamil in praise of their gods.
- During their travels the Alvars and Nayanars identified certain shrines as abodes of their chosen deities. Very often large temples were later built at these sacred places. These developed as centres of pilgrimage. Singing compositions of these poet-saints became part of temple rituals in these shrines, as did worship of the saints’ images.
- Tradition reckons 12 Alvars, of which Andal is the only female. Hence, statement 1 is correct.
- Andal composed two works in her short life (she lived only for 15 years). Both are in Tamil and are unique in their literary, philosophical, religious, and artistic content.
- Her first work is the Tiruppavai, a poem of thirty verses in which Andal imagines herself to be a cowherd girl during the incarnation of Lord Krishna. She yearns to serve Him and achieve happiness not just in this birth, but for all eternity, and describes the religious vow (pavai) that she and her fellow cowgirls will take for this purpose.
- The second is the Nacciyar Tirumoli, a poem of 143 verses. Tirumoli, literally meaning “sacred sayings”, is a Tamil poetic style in which the work is composed. “Nacciyar” means goddess, so the title means “sacred sayings of our Goddess.” Hence, statement 2 is correct.
- While Andal’s poems predominantly revolve around her intense devotion to Lord Vishnu (Krishna), they also contain philosophical, religious, and artistic elements beyond just personal experiences. Hence, statement 3 is incorrect.
- Hence, option (b) is correct.

Which of the statements given above is/are correct?
Correct
Answer: C
Explanation:
Graphene is a recently discovered material made from honeycomb sheets of carbon just one atom thick.
- Statement 1 is correct: It is a two-dimensional form (allotrope) of carbon that consists of a single layer of carbon atoms arranged in a hexagonal lattice.
- Graphene has been described as wondrous stuff of the strongest material ever tested, almost 300 times stronger than steel. It is also the best heat- and electricity-conducting material to be discovered.
- There are two main ways of producing graphene. The older, and more common way, is to break down graphite, another form of carbon, into more flatter, flake-like graphene.

- Universal Banking was conceptualized in India after the recommendation of SH Khan Committee.
- They are exempted from the CRR and SLR requirements of the RBI.
How many of the above statements is/are correct?
Correct
Solution: B.
Universal banking is a system in which banks provide a wide variety of financial services, including commercial and investment services. Banks in a universal system may still choose to specialize in a subset of banking service, even though they technically offer much more to their client base. The second Narasimham committee of 1998 gave an introductory remark on the concept of the Universal banking. However, the concept of Universal Banking conceptualized in India after the SH Khan Committee recommended it as a different concept. Once the Financial Institution becomes a universal Bank, it would be compliant with the CRR and SLR requirements of the RBI.
Hence, statement 3 is incorrect.

Question 27 of 30
27. Question
1 pointsGroundwater is the backbone of rural economy in both semi-arid and arid regions of India. The past four decades have witnessed an explosion in well numbers in these regions for irrigated farming. The government finance for well digging and pump installation with capital subsidies, massive rural electrification and pervasive energy subsidies all have enabled this process to aggravate. Today, the resource is heavily over-exploited in many of these regions. Depletion is causing economic and social distress in rural areas, though the manifestation is different in different settings. In the alluvial areas of Punjab, Rajasthan and Gujarat, water tables keep falling, increasing the cost of pumping. In the hard rock areas of AP, Telangana, Karnataka and Maharashtra, there are rampant well failures and seasonal depletion. In the north western parts of India and southern peninsula, the early and rapid rural electrification, free or subsidised power to the farm sector, large productive farmers and attractive procurement prices for major cereals led to intensive use of groundwater. Zero marginal cost of pumping and lack of restriction on volume of water resulted in inefficient and unsustainable use of the resource. In the relatively groundwater-abundant eastern India, millions of marginal farmers do not own wells and inequity in access is a major challenge, with high monopoly price charged by well owners to water buyers. But the latter use the resource very efficiently, obtaining high water productivity in farming.
Which of the following is not true about groundwater depletion in the country, based on the passage?
- All parts of the country suffer from groundwater shortage,
- The manifestation of groundwater depletion may be different in different areas of the country
- Agricultural usage is one of the major reasons for over exploitation of groundwater
Which of the above statement is/ are Correct?

1 pointsSome amount was lent at 10% p.a Simple Interest. After 1 year, Rs 4400 is repaid and the rest of the amount is repaid at 20% p.a. If the 2nd year’s interest is 11/7 of the first year’s interest, find the amount of money that was lent out initially ?
Correct
Answer (C) Rs.14000
Let the amount be x.
After 1 year the amount becomes 1.1x out of which 4400 is repaid.
Interest for second year = 20% of (1.1x-4400)
(1.1x-4400)/5 = 11/7 (1.1x-x)
7.7x-30800 = 55(0.1x)
2.2x = 30800
x = 14000
Rs 14000 was lent initially

Question 30 of 30
30. Question
1 pointsOn a certain sum of money, compound interest earned at the end of three years = Rs. 1456. Compound interest at the end of two years is Rs. 880. Compute the principal invested.
Correct
Answer: C
Let principal = P, rate of interest = r %
CI earned at the end of three years = P(1 + r)3 – P = 1456
=> P(3r2 + 3r + r3) = 1456
CI earned at the end of two years = P(1 + r)2 – P = 880
=> P(r2 + 2r) = 880
Dividing one by the other we get: 3r2+3r+r3 / r2+2r
= 1456/880
We can cancel ‘r’ and solve the resulting quadratic. However, let us see if we can spot something in the numbers.
1456/880
= 728/440
Remember that the amounts at the end of three years and two years are linked to (1 + r) 3 and (1 + r) 2 respectively.
Now observe that 1728 = 123 and 144 is 122.
So, 728/440 = 1728−1000 / 1440−1000
= 1.728−1/1.440−1
=>r = 20%
The question is ” Compute the principal invested.”
Rs. 2,000 is the principal amount.
Using options you can compute the principal amount
Hence, the answer is Rs. 2000.
Choice C is the correct answer.
Incorrect
Answer: C
