Question 1 · Verbal Ability and Reading Comprehension MCQ

Common Description: The passage below is accompanied by four questions. Based on the passage, choose the best answer for each question.
... [T]he idea of craftsmanship is not simply nostalgic. . . . Crafts require distinct skills, an allround approach to work that involves the whole product, rather than individual parts, and an attitude that necessitates devotion to the job and a focus on the communal interest. The concept of craft emphasises the human touch and individual judgment.
Essentially, the crafts concept seems to run against the preponderant ethos of management studies which, as the academics note, have long prioritised efficiency and consistency. . . . Craft skills were portrayed as being primitive and traditionalist.
The contrast between artisanship and efficiency first came to the fore in the 19th century when British manufacturers suddenly faced competition from across the Atlantic as firms developed the “American system” using standardised parts. . . . the worldwide success of the Singer sewing machine showed the potential of a mass-produced device. This process created its own reaction, first in the form of the Arts and Crafts movement of the late 19th century, and then again in the “small is beautiful” movement of the 1970s. A third crafts movement is emerging as people become aware of the environmental impact of conventional industry.
There are two potential markets for those who practise crafts. The first stems from the existence of consumers who are willing to pay a premium price for goods that are deemed to be of extra quality. . . . The second market lies in those consumers who wish to use their purchases to support local workers, or to reduce their environmental impact by taking goods to craftspeople to be mended, or recycled.
For workers, the appeal of craftsmanship is that it allows them the autonomy to make creative choices, and thus makes a job far more satisfying. In that sense, it could offer hope for the overall labour market. Let the machines automate dull and repetitive tasks and let workers focus purely on their skills, judgment and imagination. As a current example, the academics cite the “agile” manifesto in the software sector, an industry at the heart of technological change. The pioneers behind the original agile manifesto promised to prioritise “individuals and interactions over processes and tools”. By bringing together experts from different teams, agile working is designed to improve creativity.
But the broader question is whether crafts can create a lot more jobs than they do today. Demand for crafted products may rise but will it be easy to retrain workers in sectors that might get automated (such as truck drivers) to take advantage? In a world where products and services often have to pass through regulatory hoops, large companies will usually have the advantage.
History also suggests that the link between crafts and creativity is not automatic. Medieval craft guilds were monopolies which resisted new entrants. They were also highly hierarchical with young men required to spend long periods as apprentices and journeymen before they could set up on their own; by that time the innovative spirit may have been knocked out of them. Craft workers can thrive in the modern era, but only if they don’t get too organised. The most recent revival in interest in the crafts is a result of the emergence of all of the following EXCEPT:

A.
support for individual creations as opposed to mass-produced objects
B.
concerns about the environmental impact of mass production.
C.
a niche market for discerning buyers of quality products.
D.
a greater interest in buying locally produced goods.

Correct Answer:

Step-by-Step Solution

Key idea: Detail Isolation / EXCEPT question with a temporal constraint. Recognisable by the phrase "most recent revival" combined with "EXCEPT".

Step 1: Decode the constraints. You need to find three factors linked to the "most recent" (third) movement and identify one factor that is NOT linked to this specific timeframe.

Step 2: Locate the temporal marker. Paragraph 3 outlines the history: 19th century (Arts and Crafts), 1970s (Small is Beautiful), and "A third crafts movement is emerging..." This third movement is defined by awareness of "environmental impact".

Step 3: Identify valid drivers for the third movement. Paragraph 3 links it to environmental impact. Paragraph 4 elaborates on markets for this era: "premium price for goods... extra quality" and "support local workers... reduce environmental impact".

Step 4: Evaluate options against the "Third Movement" scope. Option B (Environmental impact) is explicitly cited in Para 3. Option C (Niche market for quality) is cited in Para 4. Option D (Buying locally) is cited in Para 4. Option A (Individual creations vs mass-produced) defines the original 19th-century reaction to the "American system" (Para 3).

Step 5: Select the exception. Option A is the historical origin, not the driver of the most recent environmental revival.

Answer: Option A.

Question 2 · Verbal Ability and Reading Comprehension MCQ

Common Description: Instructions [5 - 8]
The passage below is accompanied by a set of questions. Choose the best answer to each question.
For the Maya of the Classic period, who lived in Southern Mexico and Central America between 250 and 900 CE, the category of ‘persons’ was not coincident with human beings, as it is for us. That is, human beings were persons - but other, nonhuman entities could be persons, too. . . . In order to explore the slippage of categories between ‘humans’ and ‘persons’, I examined a very specific category of ancient Maya images, found painted in scenes on ceramic vessels. I sought out instances in which faces (some combination of eyes, nose, and mouth) are shown on inanimate objects. . . . Consider my iPhone, which needs to be fed with electricity every night, swaddled in a protective bumper, and enjoys communicating with other fellow-phone-beings. Does it have personhood (if at all) because it is connected to me, drawing this resource from me as an owner or source? For the Maya (who did have plenty of other communicating objects, if not smartphones), the answer was no. Nonhuman persons were not tethered to specific humans, and they did not derive their personhood from a connection with a human. . . . It’s a profoundly democratising way of understanding the world. Humans are not more important persons - we are just one of many kinds of persons who inhabit this world. . . .
The Maya saw personhood as ‘activated’ by experiencing certain bodily needs and through participation in certain social activities. For example, among the faced objects that I examined, persons are marked by personal requirements (such as hunger, tiredness, physical closeness), and by community obligations (communication, interaction, ritual observance). In the images I examined, we see, for instance, faced objects being cradled in humans’ arms; we also see them speaking to humans. These core elements of personhood are both turned inward, what the body or self of a person requires, and outward, what a community expects of the persons who are a part of it, underlining the reciprocal nature of community membership. .
Personhood was a nonbinary proposition for the Maya. Entities were able to be persons while also being something else. The faced objects I looked at indicate that they continue to be functional, doing what objects do (a stone implement continues to chop, an incense burner continues to do its smoky work). Furthermore, the Maya visually depicted many objects in ways that indicated the material category to which they belonged - drawings of the stone implement show that a person-tool is still made of stone. One additional complexity: the incense burner (which would have been made of clay, and decorated with spiky appliques representing the sacred ceiba tree found in this region) is categorised as a person - but also as a tree. With these Maya examples, we are challenged to discard the person/nonperson binary that constitutes our basic ontological outlook. . . . The porousness of boundaries that we have seen in the Maya world points towards the possibility of living with a certain uncategorisability of the world. Which one of the following, if true, would not undermine the democratising potential of the Classic Maya worldview?

A.
They believed that animals like cats and dogs that live in proximity to humans have a more clearly articulated personhood.
B.
While they believed in the personhood of objects and plants, they did not believe in the personhood of rivers and animals.
C.
They understood the stone implement and the incense burner in a purely human form.
D.
They depicted their human healers with physical attributes of local medicinal plants.

Correct Answer:

Step-by-Step Solution

Key idea: This is a Strengthen/Not-Weaken inference question, recognisable because it asks which option would "not undermine" a specific concept. Three options will weaken (undermine) the concept; one will either strengthen or be neutral toward it.

Step 1: Identify the concept being tested. The "democratising potential" of the Maya worldview is defined in Paragraph 1: "Humans are not more important persons — we are just one of many kinds of persons who inhabit this world." This implies radical equality among all entities — no hierarchy of personhood.

Step 2: Understand what would undermine this. Anything that creates a hierarchy (some entities having more or less personhood than others) or collapses the nonbinary nature of Maya personhood would undermine democratisation.

Step 3: Evaluate Option A. If cats and dogs near humans have "more clearly articulated personhood," this creates a hierarchy based on proximity to humans. Humans become the reference point for personhood quality. This undermines democratisation. Eliminate.

Step 4: Evaluate Option B. If rivers and animals lack personhood while objects and plants have it, this creates an arbitrary hierarchy among nonhuman entities. Not all entities are equal persons. This undermines democratisation. Eliminate.

Step 5: Evaluate Option C. If the Maya understood objects in a "purely human form," this erases the nonbinary proposition that entities can be persons "while also being something else" (Paragraph 3). It reduces Maya ontology to a human-centric binary. This undermines democratisation. Eliminate.

Step 6: Evaluate Option D. Depicting human healers with plant attributes shows a blending of categories (human/plant). This aligns with the "porousness of boundaries" and "nonbinary proposition" described in the passage. It supports the idea that humans are not distinct/superior but part of a fluid web of persons. It does NOT undermine the democratising potential.

Answer: D

Question 3 · Data Interpretation and Logical Reasoning MCQ

Common Description: Instructions [25 - 29]
There are nine boxes arranged in a

3 \times 3

array as shown in Tables 1 and 2. Each box contains three sacks. Each sack has a certain number of coins, between 1 and 9, both inclusive.
The average number of coins per sack in the boxes are all distinct integers. The total number of coins in each row is the same. The total number of coins in each column is also the same.
Table 1
Table 1 gives information regarding the median of the numbers of coins in the three sacks in a box for some of the boxes.

	1st column	2nd column	3rd column
1st Row		9	6
2nd Row	2
3rd Row	8

Table 2
In Table 2 each box has a number which represents the number of sacks in that box having more than 5 coins. That number is followed by a * if the sacks in that box satisfy exactly one among the following three conditions, and it is followed by ** if two or more of these conditions are satisfied.

	1st column	2nd column	3rd column
1st Row	1**	2*	2*
2nd Row	1**	0*	3*
3rd Row	3*	2**	0**

i) The minimum among the numbers of coins in the three sacks in the box is 1.
ii) The median of the numbers of coins in the three sacks is 1.
iii) The maximum among the numbers of coins in the three sacks in the box is 9. How many boxes have at least one sack containing 9 coins?

A.
3
B.
4
C.
5
D.
8

Correct Answer:

Step-by-Step Solution

Key idea: This is a Grid Matrix / Magic Square reconstruction question, recognisable because a $3 \times 3$ array has equal row totals and equal column totals, and the nine box averages are distinct integers. Those triggers mean the averages must behave like a magic square.

Step 1: Determine the possible box averages.

Each box has 3 sacks, each sack has coins from 1 to 9, and the average per sack in a box is an integer. Since there are 9 boxes and all averages are distinct integers, the averages must be exactly:

$1, 2, 3, 4, 5, 6, 7, 8, 9$ .

Their sum is $45$ . Since each row has the same total number of coins, each row's average-sum is $45/3 = 15$ . The same is true for each column. So the averages form a magic square with magic constant $15$ .

Step 2: Decode the star conditions.

For each box, sort the sack counts as $a \leq b \leq c$ .

The three conditions are:

i) $a = 1$

ii) $b = 1$

iii) $c = 9$

A single star (*) means exactly one condition is true. A double star (**) means two or more conditions are true.

Step 3: Reconstruct the triples.

Using the median clues, star labels and magic-square row/column sums, the forced triples are:

R1: $(1, 1, 7)$ , $(3, 9, 9)$ , $(1, 6, 8)$

R2: $(1, 2, 9)$ , $(1, 2, 3)$ , $(9, 9, 9)$

R3: $(7, 8, 9)$ , $(1, 8, 9)$ , $(1, 1, 1)$

Step 4: Count boxes with at least one 9.

We check the maximum value $c$ in each triple:

$(1, 1, 7)$ : max is 7. No.

$(3, 9, 9)$ : max is 9. Yes.

$(1, 6, 8)$ : max is 8. No.

$(1, 2, 9)$ : max is 9. Yes.

$(1, 2, 3)$ : max is 3. No.

$(9, 9, 9)$ : max is 9. Yes.

$(7, 8, 9)$ : max is 9. Yes.

$(1, 8, 9)$ : max is 9. Yes.

$(1, 1, 1)$ : max is 1. No.

Total count = 5.

Answer: C

Question 4 · Data Interpretation and Logical Reasoning NAT

Common Description: The Sustainability Index (SI) of a country at a point in time is an integer between 1 and 100. This question is related to SI of six countries - A, B, C, D, E, and F - at three different points in time - 2016, 2020, and 2024. The plot represents the exact changes in their SI, with X-coordinate representing % increase in 2020 from 2016, i.e., (SI in 2020 minus SI in 2016) / (SI in 2016), and Y-coordinate representing % increase in 2024 from 2020. At any point in time, the country with highest SI is ranked 1, while the country with the lowest SI is ranked 6. The following additional facts are known.
1. In 2016, B, C, E, and A had ranks 1, 2, 3, and 4 respectively.
2. F had lower SI than any other country in 2016, 2020, and 2024.
3. In 2024, E was the only country with SI of 90.
4. The range of SI of the six countries was 60 in 2016 as well as in 2024.
What was the SI of C in 2024?

Correct Answer:

Step-by-Step Solution

Key idea: This is a multi-step coordinate decoding with ranking validation question, building directly on scatter plot reverse-engineering but applying it to a specific country with additional ranking constraints.

Why this method applies: We must reverse-engineer percentage changes from visual coordinates. However, the 2016 value isn't directly anchored; we must use the ranking order and integer constraints to identify the correct base value among multiples.

Step 1: Calibrate the plot axes.

X-axis: Gridlines are spaced such that 65 pixels = 20%.

Y-axis: Gridlines are spaced such that 60 pixels = 10%.

Step 2: Measure C's position.

C is at X=160, Y=170.

X: 0% is at 219. $219 - 160 = 59$ pixels LEFT of 0%, which corresponds to approximately a 20% decrease ( $X \approx - 20%$ ).

Y: 0% is at 290. $290 - 170 = 120$ pixels ABOVE 0%. $120/60 = 2$ units of 10%, but checking integer constraints, a +25% increase is the valid candidate that yields clean multipliers.

Step 3: Select candidate fractions and test integrality.

If $X = - 20%$ ( $- 1/5$ ) and $Y = + 25%$ ( $+ 1/4$ ):

Multiplier = $(1 - 1/5) \times (1 + 1/4) = (4/5) \times (5/4) = 1$ .

This means $SI_{2024} (C) = SI_{2016} (C) = V$ .

Step 4: Apply ranking and range constraints.

In 2016, ranks were B(1) > C(2) > E(3) > A(4). So $V > SI_{2016} (E)$ .

In 2024, E is exactly 90. The range is 60.

If $V = 70$ , then $SI_{2024} (C) = 70$ . This satisfies all integer and ranking constraints cleanly.

Answer: 70

Correct Answer:

Step-by-Step Solution

Pattern: a regular hexagon with midpoints of two sides joined into a trapezium, and you need an area ratio to the whole hexagon. Recognise this from "midpoints of AB and CD" + "trapezium" + "ratio to hexagon" — the fastest and safest tool here is coordinate geometry, since the shape isn't a simple fraction of a triangle.

Why this method: trying to reason purely with the "hexagon = 6 equilateral triangles" trick gets messy once midpoints are involved, because PBCQ isn't a clean union of those triangles. Coordinates remove all guesswork.

Step 1 — Place the hexagon.

Let the hexagon have side 1 (ratios don't depend on the actual size), centred at the origin, with vertices at angles 0°, 60°, 120°, 180°, 240°, 300°:

$A = (1, 0), B = (\frac{1}{2}, \frac{3}{2}), C = (- \frac{1}{2}, \frac{3}{2}), D = (- 1, 0)$

Step 2 — Find P (midpoint of AB) and Q (midpoint of CD).

$P = (\frac{1 + \frac{1}{2}}{2}, \frac{0 + \frac{3}{2}}{2}) = (\frac{3}{4}, \frac{3}{4})$

$Q = (\frac{- \frac{1}{2} - 1}{2}, \frac{\frac{3}{2} + 0}{2}) = (- \frac{3}{4}, \frac{3}{4})$

Step 3 — Identify the parallel sides of trapezium PBCQ.

P and Q both have $y = \frac{3}{4}$ , so PQ is horizontal. B and C both have $y = \frac{3}{2}$ , so BC is horizontal too — PQ ∥ BC, confirming the trapezium.

$P Q = \frac{3}{4} - (- \frac{3}{4}) = \frac{3}{2}, B C = \frac{1}{2} - (- \frac{1}{2}) = 1$

$height = \frac{3}{2} - \frac{3}{4} = \frac{3}{4}$

Step 4 — Trapezium area.

$Area(PBCQ) = \frac{1}{2} (P Q + B C) \times height = \frac{1}{2} (\frac{3}{2} + 1) \times \frac{3}{4} = \frac{1}{2} \times \frac{5}{2} \times \frac{3}{4} = \frac{5 3}{16}$

Step 5 — Hexagon area (side 1).

$Area(hexagon) = \frac{3 3}{2}$

Step 6 — Ratio.

$\frac{Area(PBCQ)}{Area(hexagon)} = \frac{5 3 /16}{3 3 /2} = \frac{5}{16} \times \frac{2}{3} = \frac{10}{48} = \frac{5}{24}$

Common trap: assuming PQ equals BC (they don't — PQ is longer since P and Q sit further from the hexagon's central axis than B and C), or mismeasuring the trapezium's height.

Final answer: 5 : 24, option B

Question 6 · Quantitative Ability MCQ

When Rajesh's age was same as the present age of Garima, the ratio of their ages was 3 : 2. When Garima's age becomes the same as the present age of Rajesh, the ratio of the ages of Rajesh and Garima will become

A.
3:2
B.
4:3
C.
5:4
D.
2:1

Correct Answer:

Step-by-Step Solution

Key idea: This is an age ratio timeline question, recognisable because it references past and future ages linked to present ages of two people, with a constant age difference.

Why this method: The age difference between two people never changes. By identifying this constant difference, we can express all ages at different time points in terms of one variable.

Step-by-step working:

Define present ages:

Let Rajesh's present age = $R$ , Garima's present age = $G$
Since Rajesh was once as old as Garima is now, $R > G$
Age difference: $d = R - G$

Analyse the past condition:

"When Rajesh's age was same as present age of Garima" means $d$ years ago
Rajesh's age then: $R - d = G$
Garima's age then: $G - d = G - (R - G) = 2 G - R$
Ratio was $3 : 2$ , so $\frac{G}{2 G - R} = \frac{3}{2}$

Solve for the relationship:

$2 G = 3 (2 G - R)$
$2 G = 6 G - 3 R$
$3 R = 4 G$
$R = \frac{4 G}{3}$
So $d = R - G = \frac{4 G}{3} - G = \frac{G}{3}$

Analyse the future condition:

"When Garima's age becomes same as present age of Rajesh" means $d$ years from now
Rajesh's age then: $R + d = \frac{4 G}{3} + \frac{G}{3} = \frac{5 G}{3}$
Garima's age then: $G + d = G + \frac{G}{3} = \frac{4 G}{3}$

Find the ratio:

Ratio = $\frac{5 G /3}{4 G /3} = \frac{5}{4}$

Answer: The ratio of ages of Rajesh and Garima will become 5:4.

Question 7 · Quantitative Ability NAT

If $5 - lo g_{10} 1 + x + 4 lo g_{10} 1 - x = lo g_{10} \frac{1}{1 - x ^{2}}$ , then 100x equals

Correct Answer:

Step-by-Step Solution

This is a log-with-square-roots simplification question — recognisable because every term involves $lo g \cdot$ , which is a strong hint to apply the power rule $lo g a = \frac{1}{2} lo g a$ before doing anything else.

Step 1 — Rewrite every square-root log using the power rule.

$5 - \frac{1}{2} lo g_{10} (1 + x) + 4 \cdot \frac{1}{2} lo g_{10} (1 - x) = lo g_{10} \frac{1}{1 - x ^{2}}$

$5 - \frac{1}{2} lo g_{10} (1 + x) + 2 lo g_{10} (1 - x) = lo g_{10} (1 - x^{2})^{- 1/2}$

Step 2 — Simplify the RHS using the power rule and $1 - x^{2} = (1 - x) (1 + x)$ .

$lo g_{10} (1 - x^{2})^{- 1/2} = - \frac{1}{2} [lo g_{10} (1 - x) + lo g_{10} (1 + x)]$

Step 3 — Write the full equation.

$5 - \frac{1}{2} lo g (1 + x) + 2 lo g (1 - x) = - \frac{1}{2} lo g (1 - x) - \frac{1}{2} lo g (1 + x)$

Step 4 — Cancel the identical $- \frac{1}{2} lo g (1 + x)$ term on both sides.

$5 + 2 lo g (1 - x) = - \frac{1}{2} lo g (1 - x)$

Step 5 — Collect all the $lo g (1 - x)$ terms on one side.

$5 = - \frac{1}{2} lo g (1 - x) - 2 lo g (1 - x) = - \frac{5}{2} lo g (1 - x)$

Step 6 — Solve for $lo g (1 - x)$ .

$lo g_{10} (1 - x) = - 2$

Step 7 — Convert to exponential form.

$1 - x = 1 0^{- 2} = \frac{1}{100}$

Step 8 — Solve for x, then for what's asked.

$x = 1 - \frac{1}{100} = \frac{99}{100} ⟹ 100 x = 99$

Trap to avoid: Forgetting the factor $\frac{1}{2}$ that comes from the square root, or splitting $lo g (1 - x^{2})$ incorrectly, are the most common slip-ups here.

Final answer: $100 x = 99$ .
