AFCAT 18th Feb 2024 (Shift 1) Memory Based Paper. (Previous Year Paper)

The correct answer is: Walking slowly.

Key Points

• Explanation: The word 'plodding' typically refers to moving or walking slowly and with heavy steps. This interpretation aligns with option 2.
• Why the other options are incorrect:
• Climbing rapidly: The term 'plodding' does not convey any sense of rapid or climbing movement; instead, it suggests a slow and deliberate pace.
• Eating slowly: While 'plodding' does imply slowness, it is specifically used to describe movement, not the act of eating.
• Sleeping for long hours: 'Plodding' does not relate to sleeping; it refers to the manner of walking or moving.
• In summary, option 2 best captures the meaning of the word 'plodding' as used in the passage, indicating walking slowly. Options 1, 3, and 4 describe different actions that do not fit the context of 'plodding.'

The correct answer is: Poachers

Key Points

• Explanation: The term "poachers" refers to individuals who hunt or capture game or fish illegally. This definition aligns directly with the statement provided in the passage. Poaching is typically done in violation of wildlife conservation laws and regulations, aiming to protect endangered species and manage wildlife populations responsibly.
• Why the other options are incorrect:
• Camouflage: This term refers to the use of materials, coloration, or illumination for concealment, making an individual or object blend in with its surroundings. It does not relate to illegal hunting or fishing.
• Conservationists: These are individuals who advocate for the protection and preservation of the environment and wildlife. They work to prevent activities like poaching, making this term the opposite of what is described.
• Guardians: This term generally refers to protectors or defenders, often in a legal or custodial sense. It does not imply illegal hunting or fishing activities.
• In summary, option 3 ("Poachers") is the correct answer, as it specifically denotes individuals who engage in the illegal hunting or capturing of wildlife, fitting the definition provided in the passage. Options 1, 2, and 4 do not match the description of illegal hunting or fishing activities.

The correct answer is: They can rotate their ankles 180 degrees.

Key Points

• Explanation: Red pandas have a unique adaptation that allows them to descend trees headfirst. They can rotate their ankles 180 degrees, which enables them to climb down with ease and maintain control. This adaptation is especially useful for navigating the arboreal environments where they live.
• Why the other options are incorrect:
• Their long tails provide balance: While it is true that red pandas have long tails that help them balance, this feature does not specifically aid them in descending trees headfirst.
• Their sharp teeth help them grip the bark: Red pandas do have sharp teeth, but these are primarily used for feeding and not for gripping tree bark while climbing down.
• They have sticky pads on their feet: Red pandas have fur-covered paws with semi-retractable claws, which provide some grip, but this is not the unique adaptation that allows them to descend headfirst.
• In summary, option 2 best describes the unique adaptation of red pandas that allows them to descend trees headfirst. Their ability to rotate their ankles 180 degrees is a specialized feature that facilitates this behavior. Options 1, 3, and 4 describe other characteristics or adaptations of red pandas but do not directly address the specific ability to climb down trees headfirst.

The correct answer is: Red pandas live primarily in trees, have unique physical adaptations and face threats from habitat loss and poaching, with conservation efforts underway to protect them.

Key Points

• Explanation: The passage covers multiple aspects of red pandas, including their arboreal lifestyle (living in trees), unique physical adaptations, and the threats they face such as habitat loss and poaching. It also mentions ongoing conservation efforts to protect them. This comprehensive summary aligns with option 4, which encapsulates all these key points.
• Why the other options are incorrect:
• Red pandas are closely related to raccoons and weasels and spend most of their time avoiding predators: This option focuses mainly on the red pandas' relations to other species and their behavior in avoiding predators, which is not the central theme of the passage.
• Red pandas have unique adaptations for living in trees and are primarily bamboo eaters: While this is true, it does not encompass the full scope of the passage, which also addresses the threats they face and conservation efforts.
• Red pandas have distinctive red coats and live in the misty mountains of Nepal, Myanmar and central China: This option highlights their physical appearance and geographical distribution but misses out on their lifestyle, threats, and conservation.
• In summary, option 4 provides a comprehensive summary of the passage by including red pandas' arboreal lifestyle, unique adaptations, the threats they face, and the conservation efforts in place. Options 1, 2, and 3 only partially cover the information provided in the passage.

The correct answer is Option 3.

Key Points

• The primary objective is to identify the most appropriate adverb that fits the context of the sentence.
• The sentence suggests that the lack of food can be observed by looking at the faces of the people.
• The adverb "closely" best fits the context as it implies a detailed and careful observation.
• Thus, the correct adverb to complete the sentence is "closely".

Therefore, the correct answer is Option 3.

Correct Sentence: "This lack of food was confirmed when one looked closely in the faces of these people."

Additional Information

• Generally: This adverb refers to something that is usually or commonly the case, which does not fit the context of careful observation.

The correct answer is Option 3.

Key Points

• Passive voice structure: The object of the active voice sentence becomes the subject of the passive voice sentence.
• In the active voice, the sentence is: "The chef prepares the meal with great care."
• To convert to passive voice: Place the object "the meal" at the beginning.
• Change the active verb form "prepares" to "is prepared" (present simple passive).
• Add the preposition "by" followed by the original subject "the chef."
• Ensure the phrase "with great care" remains at the end of the sentence for clarity.

Therefore, the correct answer is Option 3.

Correct Sentence: "The meal is prepared with great care by the chef."

Additional Information

• Option 1: "The meal was prepared with great care by the chef." – Incorrect tense (past simple passive).
• Option 2: "The meal will be prepared with great care by the chef." – Incorrect tense (future simple passive).

• Change the active verb form "have to say" to "has to be said" (passive form).

Therefore, the correct answer is Option 4.

Correct Sentence: "Little has to be said in this matter."

Additional Information

• Option 1: "Little had to be said in this matter." – Incorrect tense (past tense).
• Option 2: "In this matter, little is to be said." – Incorrect structure and verb form.
• Option 3: "In this matter, little must be said." – Incorrect modal verb usage.

The correct answer is Option 2.

Key Points

• The active sentence “He has written a best-selling novel” is in the present perfect tense (has written).
• When converting to the passive voice, the tense remains the same:
• has written → has been written

So, the correct passive construction is: A best-selling novel has been written by him.

Additional Information

Why others are incorrect:

• Option 1: was being written → past continuous (wrong tense)
• Option 3: was written → simple past (tense changes)
• Option 4: would have been written → conditional perfect (changes meaning)

Therefore, the correct answer is Option 2.

Given:

One side of the rhombus = 13 cm

One diagonal of the rhombus = 24 cm

Formula used:

Area of rhombus = (1/2) × product of diagonals

In a rhombus, diagonals bisect each other at right angles.

Using Pythagoras theorem:

Diagonal₁ = 2 × √(side² - (Diagonal₂/2)²)

Calculation:

Diagonal₂ = 24 cm

Diagonal₂/2 = 24/2 = 12 cm

Diagonal₁ = 2 × √(13² - 12²)

⇒ Diagonal₁ = 2 × √(169 - 144)

⇒ Diagonal₁ = 2 × √25

⇒ Diagonal₁ = 2 × 5 = 10 cm

Area = (1/2) × Diagonal₁ × Diagonal₂

⇒ Area = (1/2) × 10 × 24

⇒ Area = 120 cm²

∴ The correct answer is option (4).

Given:

Initial milk quantity = 10 L

Water percentage in milk = 10%

Water content = 10% of 10 L = 1 L

Milk content = 10 L - 1 L = 9 L

Required water percentage = 20%

Calculation:

Let the additional water to be added = x L.

Final water percentage = $\frac{\text{Water content}}{\text{Total liquid content}} \times 100$

Final water percentage = $\frac{(1 + x)}{(10 + x)} \times 100 = 20$

⇒ $\frac{(1 + x)}{(10 + x)} = \frac{20}{100} = 0.2$

⇒ (1 + x) = 0.2 \times (10 + x)

⇒ (1 + x) = 2 + 0.2x

⇒ (1 + x - 0.2x = 2)

⇒ (1 + 0.8x = 2)

⇒ (0.8x = 1)

⇒ $x = \frac{1}{0.8} = 1.25$

∴ The correct answer is option (2).

Here the logic is,

Hence, FISH is the correct answer.

Given:

Distance walked = 1/10 of total distance

Distance run = 1/6 of total distance

Distance (third part) = 1/5 of total distance

Remaining distance = 16 km

Formula used:

Total Distance = Sum of all individual distances

Calculations:

Let the total distance be D km.

⇒ Distance walked = D/10

⇒ Distance run = D/6

⇒ Distance (third part) = D/5

⇒ Remaining distance = 16 km

⇒ Total Distance (D) = D/10 + D/6 + D/5 + 16

⇒ To combine fractions, find the LCM of the denominators (10, 6, 5). The LCM is 30.

⇒ D = (3D/30) + (5D/30) + (6D/30) + 16

⇒ D = (3D + 5D + 6D)/30 + 16

⇒ D = 14D/30 + 16

⇒ D = 7D/15 + 16

⇒ D - 7D/15 = 16

⇒ (15D - 7D)/15 = 16

⇒ 8D/15 = 16

⇒ 8D = 16 × 15

⇒ D = (16 × 15) / 8

⇒ D = 2 × 15

⇒ D = 30 km

∴ The total distance is 30 km.

The logic follows here is :

(Product of upper numbers) ÷ (Sum of lower numbers) = Middle number.

Given:

Selling price (SP) = ₹30,030

Loss percentage = 22%

Required gain percentage = 22%

Formula used:

Cost Price (CP) = SP / (1 - Loss%)

New Selling Price (New SP) = CP × (1 + Gain%)

Calculation:

Cost Price (CP):

⇒ CP = 30030 / (1 - 22/100)

⇒ CP = 30030 / (0.78)

⇒ CP = ₹38,500

New Selling Price (New SP):

⇒ New SP = 38500 × (1 + 22/100)

⇒ New SP = 38500 × 1.22

⇒ New SP = ₹46,970

∴ The correct answer is option (3).

CONCEPT:

The total time taken for the given activity should be calculated first and then we have to find out the angle covered by the hour hand in that particular time interval.

We know that, Hour hand covers 360**°** in 12 hours.

Angular distance covered in 1 hour = 360**°/12 = 30°**

That is, Angular distance covered in 60 minutes = 30**°**

Then, Angular distance covered in 1 minutes = 30º/60 = 1/2**°**

CALCULATION:

Total time taken by Arjun for the work = 5:50 - 1:00 = 4:50.

Thus, he took 4 hours and 50 minutes to complete the work.

Angular distance covered by the hour hand in 4 hour = 4 × 30**°** =120**°**

Angular distance covered by the hour hand in 50 minutes = 50 × ½**°** = 25**°**

Then, total angular distance covered by the hour hand = 120° + 25° = 145°.

Hence, 145° is the correct answer.

The correct answer is Option 2.

Given:

The Loss incurred by selling an article at ₹2114 is 65% of the gain attained by selling the same article at ₹2675.

Formula used:

Let Cost Price (CP) = x

Loss = CP - Selling Price (SP)

Gain = SP - CP

Calculations:

Loss = CP - 2114

Gain = 2675 - CP

(CP - 2114) = 0.65 × (2675 - CP)

⇒ CP - 2114 = 1738.75 - 0.65CP

⇒ CP + 0.65CP = 1738.75 + 2114

⇒ 1.65CP = 3852.75

⇒ CP = 3852.75 / 1.65

⇒ CP = 2335

∴ The correct answer is option (1).

Given:

Speed at which A travels first time = 187 kmph

Late time when traveling at 187 kmph = 330 minutes

Speed at which A travels second time = 198 kmph

Early time when traveling at 198 kmph = 330 minutes

Concept used:

Distance = [( S1 × S2 ) ÷ (S2 – S1) ] × time difference

S1 & S2 are two different speeds

S2 - S1 = Speed Difference = 198 - 187 = 11 kmph

Explanation:

S1 = 187 kmph

S2 = 198 kmph

Time difference = (330 + 330) = 660 minutes

Distance = [(198 × 187) ÷ (11)] × (660 / 60)

= 37026 km

∴ The correct answer is option (3).

Given:

Pipe A can fill the tank in 170 hours.

Pipe B can fill the tank in 204 hours.

Pipe C can fill the tank in 255 hours.

Formula used:

Total work = Efficiency × Total days.

Concept used:

If a person can do a work in m days, part of the work done by the person is $\dfrac{1}{m}$

Calculations:

A's one hour work = $\dfrac{1}{170}$

B's one hour work = $\dfrac{1}{204}$

C's one hour work = $\dfrac{1}{255}$

Total work by all in 34 hours = ($\dfrac{1}{170}$ + $\dfrac{1}{204}$ + $\dfrac{1}{255}$) × 34

= $\dfrac{6 + 5 + 4}{1020}$ × 34

= $\dfrac{15}{1020}$ × 34 = $\dfrac{1}{2}$

So, remaining work = 1 - $\dfrac{1}{2}$ = $\dfrac{1}{2}$

Work done by A and C,

= $\dfrac{1}{170}$ + $\dfrac{1}{255}$

= $\dfrac{3 + 2}{510}$

= $\dfrac{5}{510}$

Time taken by A and C to complete remaining work and B is closed,

= $\dfrac{1}{2}$ ÷ $\dfrac{5}{510}$

= 51 hours

∴ The correct answer is option (3).

Given:

Two fair dice are thrown at random independently.

We need to find the probability that the average of the values on their upper faces is 4.

Formula used:

Probability = $\dfrac{\text{Favorable outcomes}}{\text{Total possible outcomes}}$

Calculations:

Total possible outcomes when two dice are thrown = 6 × 6 = 36

For the average of the values to be 4, the sum of the values on the upper faces must be 8 (since Average = Sum ÷ 2).

We now find the pairs of dice rolls where the sum is 8:

(2, 6), (3, 5), (4, 4), (5, 3), (6, 2)

Number of favorable outcomes = 5

⇒ Probability = $\dfrac{\text{Favorable outcomes}}{\text{Total possible outcomes}}$

⇒ Probability = $\dfrac{5}{36}$

Given:

A contributes one-third of the capital.

B contributes as much as A and C together.

Total profit = ₹1,26,000

Formula used:

Profit Share = (Capital Contribution / Total Capital) × Total Profit

Calculations:

Let the total investment be ‘x’  

⇒ A’s contribution = x/3

⇒ Contribution of B + Contribution of C = 2x/3

Let B’s contribution be ‘y’

⇒ C’s contribution = 2x/3 - y

According to the given condition,

⇒ y = (2x/3 - y) + x/3

⇒ y = x – y

⇒ y = x/2

⇒ C’s contribution = 2x/3 – x/2 = x/6

⇒ The share of A, B and C will be proportionate to x/3, x/2 and x/6 respectively

⇒ The ratios will be 1/3: 1/2: 1/6 = 2: 3: 1

⇒ Amound recieve by C = 1/6 × 1,26,000 = 21000

The correct answer is Option (4).

Drawing the diagram according to the given information,

Distance between house to mall = $\sqrt {{\text{A}}{{\text{F}}^2} + {\text{E}}{{\text{F}}^2}}$

AF = AB + BF = 33 + 30 = 63 m

Distance between house to mall = $\sqrt {{{63}^2} + {{16}^2}}$ = $\sqrt {4225} ;$

Distance between house to mall = 65 m

Hence, 65 m is the correct answer

The correct answer is Proxima Centauri.

• Proxima Centauri Star System is closest to Earth.
• Proxima Centauri has two confirmed exoplanets: Proxima Centauri b and Proxima Centauri c.
• Sirius is the brightest star in the night sky.

Given:

A finishes task in 12 days

B finishes task in 18 days

A and B work together for 5 days

B and C complete remaining work in 4 days

Calculations:

Total Work = LCM of (12, 18) = 36 units

A's efficiency = Total Work / A's days = 36 / 12 = 3 units/day

B's efficiency = Total Work / B's days = 36 / 18 = 2 units/day

Combined efficiency of A and B = A's efficiency + B's efficiency = 3 + 2 = 5 units/day

Work done by A and B in 5 days = 5 units/day × 5 days = 25 units

Remaining Work = Total Work - Work done by A and B = 36 - 25 = 11 units

Work done by B and C in 4 days = 11 units

Combined efficiency of B and C = Work done / Days worked = 11 units / 4 days = 11/4 units/day

C's efficiency = Combined efficiency of B and C - B's efficiency = 11/4 - 2

⇒ C's efficiency = 11/4 - 8/4 = 3/4 units/day

Time taken by C alone to complete 60% of the work:

60% of Total Work = 0.60 × 36 = 21.6 units

Time for C to complete 60% work = (60% of Total Work) / C's efficiency

⇒ Time = 21.6 / (3/4)

⇒ Time = 21.6 × (4/3)

⇒ Time = 28.8 days

The pattern followed here is :

For 5 % 7 = 72,

(5 + 7) × 6 = 12 × 6 = 72;

And,

3 % 8 = 66,

(3 + 8) × 6 = 11 × 6 = 66;

Similarly,

6 % 8 = ?

(6 + 8) × 6 = 14 × 6 = 84;

Hence, ‘84’ is the correct answer.

The correct answer is Tapeworms

Key Points

• Tapeworm belongs to the class Platyhelminthes of Kingdom-Animalia.

• The organisms of phylum Platyhelminthes have their body unsegmented.

• In tapeworms, the new segments (called proglottids**) originate from the neck i.e. anterior part of the body.** Hence, tapeworms exhibit pseudo-metamerism.

• They also live in human intestines.

• Unsegmented body- The body is not divided into segments.Ex-planaria(phylum-Platyhelminthes).

• Metamerically segmented-Body is divided into equal segments.Ex-earthworm(phylum-Annelida),centipede(phylum-Arthropoda)

Additional Information

• Caterpillars:
• One of the most prevalent categories of invertebrates is the insect.
• Their bodies are hard on the outside and comprised of three parts: the head, thorax, and abdomen.
• Most insects have six legs and wings.
• Insects include ants, flies, caterpillars, beetles etc.
• Silkworms
• The life cycle of a silkworm is Egg­ > Caterpillar ­> Pupa­ > Adult.
• The egg is the first and primary stage of the life cycle of Silkworm.
• The egg is laid by a  female moth and the egg is the size of small dots.
• More than 350 eggs are laid by a female moth at a time.
• The eggs hatch in the springtime due to the warmth in the air.
• This procedure takes place once a year.
• Moths
• They are in the order Lepidoptera, which also includes butterflies.
• The wings are covered in scales, which give them their distinctive appearance.
• They use this proboscis to suck nectar from flowers.
• They use their antennae to detect pheromones released by female moths.
• They help to spread pollen from flower to flower.

Given:

Weight of apples = 5 kg

Cost per kg of apples = ₹120

Weight of oranges = 3 kg

Cost per kg of oranges = ₹180

Formula used:

Weighted Average Cost per kg = ∑(Weight × Cost per kg) / ∑(Weight)

Calculation:

Weighted Average Cost per kg = (5 × 120) + (3 × 180) / (5 + 3)

⇒ Weighted Average Cost per kg = 600 + 540 / 8

⇒ Weighted Average Cost per kg = 1140 / 8

⇒ Weighted Average Cost per kg = ₹142.50

∴ The correct answer is option (2).

Given:

X can finish the work in 141 days

He worked for 57 days

Y completed the remaining work in 84 days

Formula used:

Total Work = LCM of 141 and 84 = 141 units (assumed)

Efficiency = Work ÷ Time

Time taken together = Total work ÷ (X’s efficiency + Y’s efficiency)

Calculations:

X’s efficiency = 141 ÷ 141 = 1 unit/day

Work done by X in 57 days = 57 × 1 = 57 units

Remaining work = 141 - 57 = 84 units

Y’s efficiency = 84 units ÷ 84 days = 1 unit/day

Total efficiency = 1 + 1 = 2 units/day
