Correct Answer : C

The average age will be 56 years.

With no one leaving or joining, every one of the 16 professors is four years older, so the total age rises by \(16 \times 4 = 64\) years and the average rises by exactly 4 years: \(52 + 4 = 56\).

The size of the group does not matter: when every member ages by the same amount, the average ages by that amount too.

68 years adds 16 (the number of professors) instead of 4, and 58 years adds 6. 'None of these' is wrong because 56 is offered.

Correct Answer : A

Find the side, then the perimeter, then price it.

\[ \text{side} = \sqrt{289} = 17 \text{ ft} \]

\[ \text{perimeter} = 4 \times 17 = 68 \text{ ft} \]

\[ \text{cost} = 68 \times 58 = \text{Rs. } 3944 \]

The fence follows the boundary, so it is priced by perimeter, not area - the data are complete, so "cannot be determined" is a trap.

Correct Answer : D

\[ \text{SI} = \frac{P \times R \times T}{100} \]

\[ \text{SI} = 920 - 800 = 120 \quad\Longrightarrow\quad 120 = \frac{800 \times R \times 3}{100} = 24R \]

\[ R = 5\% \]

At \( 5 + 3 = 8\% \):

\[ \text{SI} = \frac{800 \times 8 \times 3}{100} = 192 \quad\Longrightarrow\quad \text{amount} = \text{Rs. } 992 \]

The extra 3% over three years adds \( 800 \times 0.09 = 72 \) - the same answer in one step.

Correct answer: Are flexible

The passage says the rules are not embodied and then explains what follows: the extent of their application depends upon the particular statutory framework under which the authority acts, and the legislature may even dispense with a requirement. Rules that bend to the framework are flexible, not vague or unintelligible.

Correct Answer : A

Correct answer: 21 June

The longest day in the northern hemisphere is the summer solstice, about 21 June, when the North Pole is tilted most directly towards the Sun and the Sun stands overhead at the Tropic of Cancer. On the same date the southern hemisphere has its shortest day, since the two are always opposite - which is the clearest evidence that the seasons come from the tilt rather than from distance to the Sun. The winter solstice around 21 December reverses the arrangement, with the Sun overhead at the Tropic of Capricorn. Between them lie the equinoxes, about 21 March and 23 September, when the Sun is overhead at the equator and day and night are nearly equal everywhere. The exact dates shift by a day either way because the year is not a whole number of days.

Correct answer: A warm ocean current in the North Atlantic

The Gulf Stream is a warm surface current that carries tropical water from the Gulf of Mexico up the eastern coast of North America and then across the Atlantic towards northwestern Europe, where it continues as the North Atlantic Drift. Its climatic effect is large. Britain, Ireland and Norway are far milder than their latitudes would suggest - ice-free ports in Norway lie north of the Arctic Circle, while Labrador at the same latitude on the other side of the Atlantic freezes. It is part of the wider thermohaline circulation, in which warm surface water flowing north cools, becomes denser and sinks, returning south at depth. That overturning is sensitive to freshwater input from melting ice, which is why it is closely watched. The Peru or Humboldt Current is the cold one, and the Sahara wind is the Harmattan.

Correct Answer : A

Correct answer: Parliament

Article 248 vests residuary powers in Parliament, which has exclusive power to make any law on a matter not enumerated in the Concurrent or State List, including the power to impose a tax not mentioned in either. This follows the Canadian model and departs from the American and Australian, where residuary powers rest with the states - a deliberate choice, and one of the features that makes Indian federalism centre-heavy. It matters because the lists were drawn up in 1949 and could not anticipate everything: cyberspace, information technology, space, and much else fall to Parliament through this article. The residuary power is also mentioned as Entry 97 of the Union List, which makes the position doubly clear. The courts have held that it should be resorted to only when a matter cannot be brought within any entry in the three lists, read as broadly as their language allows - so it is a residual power in fact as well as in name.

This is an example of guided discovery.

In guided discovery the learners explore and analyse the material themselves, but the teacher structures the experience with questions, hints and feedback so that they arrive at the concept. The stem describes exactly that combination: exposure and analysis by the learners, with the teacher's support.

Expository teaching is the reverse, where the teacher explains the content directly (Ausubel's model). Observational modelling is learning by watching and imitating a model, as in Bandura's theory. Pre-dispositional learning is not a standard teaching method.

Correct Answer : C

The statement that is not correct is According to Thunen's model-I the intensity of production of a particular crop increases with distance from the market.

In von Thunen's first model, for a single crop, the intensity of production falls with distance from the central market town. Transport costs rise with distance, so economic rent falls, and it pays to apply less labour and capital to each hectare the farther the land lies from the city.

The other statements are correct. The theory is built on economic (location) rent, its aim was to show how and why land use varies with distance from the market, and in the second model several land uses compete, forming concentric rings of different land use around the town.

The one that is not a Korku subtribe is Pateliya.

The Korku of the Satpura region are divided into subgroups such as the Mowasi, Bawaria, Bondoya (printed Bodoya), Ruma and Nahala, names recorded in ethnographic accounts of the tribe.

Pateliya (Patelia) is a group of the Bhil tribe in the Jhabua and Alirajpur region of western Madhya Pradesh, not a division of the Korku.

Correct Answer : B

The key's answer is Bhumihar.

B.P. Keshari wrote on the Sadans, the non-tribal, Indo-Aryan-speaking communities of Chota Nagpur. The question asks which of the castes he did not count among them. The text of his work could not be read, so the key's choice of Bhumihar could not be confirmed.

Which of Teli, Turi and Bhokta he counted as Sadan could not be checked either. Turi is on the state's Scheduled Caste list, and a source found says Bhogta was moved to the Scheduled Tribe list in 2022 as a synonym of Kharwar, but those listings are not Keshari's classification, so the answer rests on the key.

The statement is Kepler's second law, the law of areas.

Kepler's second law says that the line joining a planet to the Sun sweeps out equal areas in equal intervals of time. It means a planet moves faster when it is near the Sun and slower when it is far away, and it follows from the conservation of the planet's angular momentum about the Sun.

Kepler's first law is the law of orbits: each planet moves in an ellipse with the Sun at one focus. The law of periods is his third law, T² proportional to a³. Newton's law of gravitation gives the force between masses, and Newton's third law concerns action and reaction.
