Correct Answer : A

Let the number be \( 10a + b \) with \( a + b = 12 \).

Reversing adds 18:

\[ (10b + a) - (10a + b) = 9(b - a) = 18 \quad\Longrightarrow\quad b - a = 2 \]

\[ a = 5, \quad b = 7 \quad\Longrightarrow\quad 57 \]

Correct Answer : C

\[ 1 \text{ km/hr} = \frac{5}{18} \text{ m/s} \]

\[ 45 \text{ km/hr} = 12.5 \text{ m/s} \]

\[ \text{total distance} = 12.5 \times 30 = 375 \text{ m} \]

\[ \text{bridge} = 375 - 130 = 245 \text{ m} \]

That total covers the train plus the bridge, so the train's own length is subtracted at the end.

Correct answer: Beak

The relation is vessel : the part it is brought to, or more simply whole : the part that takes in food. Drink passes from the cup to the lip; a bird takes its food with its beak. Bush, grass and forest are places, not parts of the bird.

Correct Answer : A

The matching pair is Aggravate : Alleviate.

Exacerbate means to make a problem worse; mitigate means to make it less severe. The pair is therefore two opposites, in the order 'make worse : make less bad'. Aggravate means to make worse and alleviate means to ease, so the pair has the same relation in the same order.

Alleviate : Precipitate is the wrong way round and its second word does not mean 'worsen': precipitate means to bring on suddenly. Aggravate : Precipitate pairs two words that both push events on rather than opposites. Emancipate (set free) and exonerate (clear of blame) are not opposites and have nothing to do with making things worse or better.

Correct Answer : C

Correct answer: 81

The gaps are 8, 16, 24, which follow no constant pattern, so the rule lies in the terms rather than in the steps between them. Each term is the square of an odd number: position 1 gives 1 and position 4 gives 49. The next position is 5, which gives 81. As a check, the same rule applied to the earlier positions reproduces 1, 9, 25, 49 exactly, so it accounts for every term shown and not merely the last. Subtracting one from each square gives numbers that factorise neatly, which is sometimes the easier way to see the pattern.

Correct answer: None of these

Each 7 that has a 6 before it must be checked for what precedes that 6. Working through the row, every such 6 turns out to have an 8 before it, or the 7 has no 6 before it at all - so the count is not one of the figures offered, and the answer is none of these.

The novel 'Astarag' (Astaraag) is by Homen Borgohain.

Homen Borgohain was a leading Assamese novelist, short-story writer and journalist, who won the Sahitya Akademi Award for his novel Pita Putra.

The other two are also Assamese novelists, which is why the options are close. Nirupama Borgohain, his wife, won the Sahitya Akademi Award for Abhijatri, and Rita Chowdhury won it for Deo Langkhui. Since the author is among the options, 'None of them' is wrong.

USG stands for Ultrasonography.

Ultrasonography is the imaging technique that uses high-frequency sound waves and their echoes to produce pictures of internal organs and of the foetus during pregnancy. It uses no ionising radiation.

'Undersized gland' and 'Unsegmented gonads' are not medical abbreviations for USG, so 'None of the above' is wrong as well.

It is routinely used to examine the abdominal organs, the heart (as echocardiography) and the developing foetus during pregnancy.

Correct Answer : B

Statements (i), (ii) and (iii) are correct, so the answer is (i), (ii) and (iii) only.

ICT gives access to more precise and accurate data of many kinds (i), it helps firms find the areas where they can gain a competitive advantage (ii), and ICT products change the environmental footprint of other products and activities, for example by enabling remote work or smarter energy use (iii).

Statement (iv) describes the opposite of ICT-enabled manufacturing. Energy-intensive, standardised, departmentalised production is the old mass-production model; ICT makes manufacturing more flexible, customised, integrated across departments and generally less energy-intensive. Option B is the only one that leaves out (iv).

The heavy afternoon rains of the equatorial belt are convectional. Intense midday heating makes moist surface air rise rapidly, and as it cools it builds towering cumulonimbus cloud that breaks in a downpour, usually between two and four in the afternoon.

The pattern repeats almost every day, which is why the equatorial regions have no dry season.

Correct Answer : D

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 : C

The key gives Supriya Jatav, of Madhya Pradesh, as the karate player who won a mixed event gold and an individual bronze in the 55 to 61 kg kumite category at the US Open Karate Championships in Las Vegas. News reports from 2022 describe her as the first Indian karate player to win a gold medal in the mixed event there.

I could not confirm the exact year from a primary source, since one reference gives an earlier date for a US Open title, so the answer rests on the key and the news reports. Sandhya Shetty, Bhavisha Singh and Tashvi Menghi are the other names offered.
