Correct Answer : C

The pipe weighs 3.696 kg.

The external radius is 4 cm and, with a 1 cm wall, the internal radius is 3 cm. The volume of iron is the difference of the two cylinders:

\[ \begin{aligned} V &= \pi(4^{2} - 3^{2}) \times 21 \\ &= \tfrac{22}{7} \times 7 \times 21 = 462\ \text{cm}^{3} \\ \text{mass} &= 462 \times 8 = 3696\ \text{g} \end{aligned} \]

3696 g is 3.696 kg. 36.96 kg misplaces the decimal point. A solid rod of the same size would weigh \(\tfrac{22}{7} \times 16 \times 21 \times 8\) g, about 8.4 kg, so forgetting the hollow core does not give the other options either.

Correct Answer : B

First, find the smallest number that leaves a remainder of 7 when divided by 9, 10, and 15. This number is of the form \(k \times \text{LCM}(9,10,15) + 7\). LCM of 9, 10, 15 is 90. The numbers are 97, 187, 277, etc. We need to find a number of this form that is just less than 1936. Let's divide 1936 by 90. \(1936 = 21 \times 90 + 46\). The nearest multiple of 90 below 1936 is \(21 \times 90 = 1890\). The required number is \(1890+7=1897\). The number that must be subtracted from 1936 to get 1897 is \(1936 - 1897 = 39\).

Correct answer: V

All seven face north, so right means east. W sits five places to T’s right and not at an end, which puts T first and W sixth. Y is exactly in the middle, fourth, and U three places to Y’s right, seventh. Z must be three places from X and not beside Y, which leaves only one filling. From left to right the row reads T, Z, V, Y, X, W, U.

Counting two places to T’s right gives Z and then V.

A Johnson counter is a shift register with inverted feedback, and its stages produce a set of repetitive waveforms offset in phase, which is what makes it a standard waveform generator.

Of the four, the highest rainfall is received in Rajsamand.

Rainfall in Rajasthan decreases from the south and south-east towards the north-west, because the monsoon winds weaken as they move inland and the Aravalis lie parallel to the Arabian Sea branch. Rajsamand, in the southern Aravali region, is much wetter than the desert districts.

Bikaner, Churu and Jaisalmer are in the arid north-west and west, and Jaisalmer is among the driest districts of the state.

Hasrat Mohani coined the slogan Inquilab Zindabad.

The Urdu poet and freedom fighter used it in the 1920s, and Bhagat Singh and B.K. Dutt made it famous by shouting it in the Central Legislative Assembly in 1929. Mohani was also the first to demand complete independence, at the Ahmedabad Congress of 1921.

Correct Answer : A

Correct answer: Both Statement I and Statement II are correct

Both are true and the second is the reason for the first. Radon is a noble gas: it is chemically inert, so adsorbents have little hold on it, and it is a gas, so particulate filters pass it entirely.

Control therefore acts on entry rather than on the air already indoors - sealing cracks and service penetrations, and above all sub-slab depressurisation, which draws soil gas from beneath the floor and vents it above the roof so that it never enters at all.

Correct Answer : A

The first is true and the second is false: the gate is a capacitance, so switching it means moving real charge, and at high frequency that charge dominates the drive power. Zero steady current and zero switching charge are quite different claims, and confusing them leads to underestimating gate drive requirements badly. A static property and a dynamic one have to be quoted separately.

Correct Answer : C

Handing the causal part to a planner and the numeric part to a scheduler lets each use decades of specialised development, at the cost of iterating when the decomposition is imperfect. Complexity is unchanged and optimality is generally lost. Organisational separation is a side effect rather than a benefit. Accepting a loss of optimality in exchange for being able to use two mature tools is a trade that should be made explicitly rather than by default.

Correct Answer : A

An interpreted program runs slower.

A compiler translates the whole program into machine code once, before it runs. An interpreter analyses and executes the source (or an intermediate form) statement by statement while the program runs, repeating that work every time a statement is executed, for example on each pass through a loop. That overhead makes interpretation slower.

So 'faster' and 'the same speed' are wrong, and 'may be faster or slower' does not describe the general case the question asks about.

Correct Answer : D

Expression needs the presence of lactose and absence of glucose.

The structural genes come from the trp operon, but their transcription is now controlled by the lac promoter region. That region responds to two signals: lactose (as allolactose) removes the lac repressor, and the absence of glucose raises cAMP so that CAP-cAMP can activate transcription.

Glucose keeps cAMP low and so blocks efficient expression, and without lactose the repressor stays bound. Tryptophan is irrelevant, because the trp promoter and operator that respond to it are no longer present.

The Public Accounts Committee consists of 22 members: 15 from the Lok Sabha and 7 from the Rajya Sabha, so (B) is correct. The Lok Sabha members are elected each year by the House from among its members by proportional representation with the single transferable vote, and the Rajya Sabha members are chosen in the same way. Option (A) has 15 members in all and leaves out most of the Rajya Sabha share. Option (C) gives 16 and option (D) gives 27, which do not match the strength of 22 laid down for the committee.

This explains the Müller-Lyer illusion.

Richard Gregory's misapplied size-constancy explanation notes that the arrow-fins of the Muller-Lyer figure resemble corners: outward fins look like the inside corner of a room (which looks farther away), and inward fins like the outside corner of a building (which looks nearer). The brain enlarges the line that seems farther, so the line with outward fins looks longer.

The Ponzo illusion uses converging lines like railway tracks, the Ames room uses a distorted room seen from one viewpoint, and the Poggendorff illusion involves a diagonal line interrupted by a rectangle; none rests on the corner explanation.

The movement began in the Nalgonda district of Hyderabad state.

The Telangana peasant armed struggle is usually dated from July 1946, when a deshmukh's men killed the village activist Doddi Komarayya at Kadavendi in Jangaon taluk, then part of Nalgonda district. The rising spread from Nalgonda to Warangal and Khammam and was led by the communists through the Andhra Mahasabha.

Warangal was drawn in soon after but was not where the movement began, Bidar saw no comparable rising, and Dinajpur in Bengal was the centre of the Tebhaga movement of 1946-47.

Territorially the largest unit of local government in the USA is the County.

Almost every US state is divided into counties (called parishes in Louisiana and boroughs in Alaska), and the county is the largest local unit by area. It administers state laws locally, runs courts, records, roads and elections, and contains the smaller units within it.

City municipalities and towns govern a single settlement or a small area within a county, and special districts are single-purpose bodies such as school or water districts, usually covering only part of a county.

The correct answer is Ghan Vadya.

Idiophones are instruments made of solid material, such as cymbals and bells, so they are ghana vadya.

Examples of idiophones are the manjira and the jhanjh, in which the body of the instrument itself vibrates.

Sushir vadya are wind instruments, avanaddha vadya are drums with skin, and taranga vadya is not the class of idiophones.

The matching is: measures towards globalisation with the liberalised inflow of FDI (III), off-shoring with globalisation (I), FERA with FEMA (II), and Mr. Arthur Dunkel with the Uruguay Round (IV), giving III I II IV, option A. The Foreign Exchange Regulation Act was replaced by the Foreign Exchange Management Act in 1999, and Arthur Dunkel, as Director General of GATT, put forward the Dunkel draft text of the Uruguay Round. Options B, C and D mispair at least two of the items.

Correct Answer : D

The extensive properties are (i) and (iv), volume and heat capacity.

An extensive property depends on the amount of matter in the system: double the system and the property doubles. Volume and heat capacity both behave this way, since twice the gas fills twice the volume and needs twice the heat for the same temperature rise.

Pressure and density are intensive: they do not change when the system is enlarged. Density in particular is the ratio of two extensive quantities (mass over volume), and such a ratio is always intensive. So any option including (ii) or (iii) is wrong, and (iv) only leaves out volume.
