Correct answer: 99996

The largest five-digit number is 99999. Divide it by 13 and subtract whatever is left over.

\[99999 = 13\times 7692 + 3\]

\[99999 - 3 = 99996 = 13\times 7692\]

The three numbers above it - 99997, 99998 and 99999 - leave remainders 1, 2 and 3, so 99996 is the greatest five-digit multiple of 13.

Correct Answer : C

Two series are interleaved and run in opposite directions.

\[ \text{positions 1, 3, 5, 7, 9: } 3,\; 6,\; 9,\; 12,\; 15 \quad (+3) \]

\[ \text{positions 2, 4, 6, 8, 10: } 7,\; 5,\; 3,\; 1,\; \mathbf{-1} \quad (-2) \]

The tenth term belongs to the falling series:

\[ 1 - 2 = -1 \]

Nothing in the rule stops the second series going negative, which is what makes \( -1 \) the answer rather than 3.

Clearly, mechanization would speed up the work and increase the production. So, argument I is strong enough. Argument II is vague because mechanization will only eliminate wasteful employment, not create unemployment.

Your Answer : (Not Answered)

Correct Answer : B

Correct answer: Only argument II is strong

Argument II raises a genuine difficulty: the cost would fall on a treasury already stretched. Argument I claims free schooling is the only way to raise literacy, which is too strong - teachers, schools and attendance matter as much. Only II is strong.

Correct Answer : C

CLOCK is spelt as CMNCL.

Compare WATCH with WBSCI letter by letter:

The pattern of shifts is 0, +1, -1, 0, +1. Applying it to CLOCK: C stays C, L becomes M, O becomes N, C stays C, K becomes L, giving CMNCL.

The other options break the pattern: CKPCJ reverses every shift, CKNCJ moves L and K backwards instead of forwards, and CMNDJ changes the fourth letter, which should stay C, and moves K backwards.

Correct Answer : C

The lines "Malaiyulae pirapinum malaiku avaitham en seiyum" are from the Kalithogai, option C.

The Kurunthogai, Agananooru and Natrinai are other Sangam anthologies and do not hold these lines. The booklet tick agrees with the final key.

The Kalithogai is the fifth anthology in the Ettuthogai and its metre is kali, a lyrical form often used in dialogues of love. The image in the line, that the mountain does not mind where the stone is born, is typical of its poems. The Kurunthogai, Agananooru and Natrinai use the akaval metre instead.

Correct Answer : A

Iodised salt is a mixture of potassium iodide and common salt.

Common salt (sodium chloride) is fortified by adding a small amount of an iodine compound, traditionally potassium iodide and now often potassium iodate, to prevent iodine deficiency disorders such as goitre. The additive is simply mixed in, and each substance keeps its own properties, so the product is a mixture, not a compound.

Molecular iodine is not used, because it is volatile and would escape, and it does not combine with sodium chloride to form a compound. 'Only potassium iodide' is wrong because most of iodised salt is still common salt.

The statement that is not a method of preventing desertification is discourage plantation on sandy soil to avoid water loss.

Vegetation is the main defence against a spreading desert. Trees, shrubs and grasses bind sand, slow the wind and add organic matter, so planting on sandy soil is exactly what desert control programmes promote, through shelterbelts and sand dune stabilisation.

The other three are genuine measures: a green belt to stop the desert moving east, social and agro forestry with local species, and a ban on cutting plants that conserve soil and water.

This is the greenhouse effect.

Short-wavelength sunlight passes through the glass and is absorbed by the seats and dashboard, which then re-radiate at much longer infrared wavelengths. Glass is opaque to that infrared, so the heat is trapped, and the closed windows also prevent it escaping by convection.

Correct answer: The 61st Amendment

The 61st Amendment, passed in 1988 and effective from 1989, lowered the voting age for elections to the Lok Sabha and the state legislative assemblies from 21 to 18 by amending Article 326. The stated reasoning was that the country’s young people were politically conscious and literate enough to be given the franchise, and that including them would deepen democracy. It added some fifty million voters at a stroke. The other amendments named are all significant in their own right. The 42nd of 1976, passed during the Emergency, is called the mini-Constitution for the sheer number of changes it made, including the insertion of socialist and secular into the Preamble and the Fundamental Duties. The 44th of 1978 reversed many of them and removed the right to property from the fundamental rights. The 52nd of 1985 introduced the anti-defection law in the Tenth Schedule.

Correct answer: The Godavari

The Godavari, about 1,465 km long, is the longest river whose entire course lies within India. It rises at Trimbakeshwar in Maharashtra and flows east across the Deccan through Telangana and Andhra Pradesh to the Bay of Bengal, where it forms a large delta. It is often called the Dakshina Ganga, the Ganga of the south. The Ganga is longer at about 2,525 km but flows into Bangladesh before reaching the sea, so it does not qualify. The Brahmaputra rises in Tibet as the Yarlung Tsangpo and also crosses into Bangladesh; the Indus rises in Tibet and flows chiefly through Pakistan. The Godavari is the second longest river in India after the Ganga, and its basin is the largest of the peninsular rivers. Its major tributaries are the Pravara, Manjira, Indravati and Sabari, and the Polavaram and Sriram Sagar projects are built on it.

The Government of India Act, 1935 influenced the Constitution more than any other single source.

Something like two-thirds of its provisions were carried over - the federal scheme, the division of powers into three lists, the office of governor, the emergency provisions and much of the administrative machinery.

Correct Answer : C

The new scheme proposed 7 slabs.

The optional new tax regime announced in the Union Budget 2020-21 had these rates on income: up to Rs 2.5 lakh, nil; Rs 2.5-5 lakh, 5%; Rs 5-7.5 lakh, 10%; Rs 7.5-10 lakh, 15%; Rs 10-12.5 lakh, 20%; Rs 12.5-15 lakh, 25%; and above Rs 15 lakh, 30%.

Counting the nil band, that makes seven slabs. Answering 6 counts only the slabs that carry tax, and 5 and 8 match no version of the scheme.
