SSC CHSL Tier-1 2022: Official Paper (Held On: 20 March, 2023 Shift 4) (Previous Year Paper)

The logic followed here is:

Logic: (First Number)³ = Second Number

Let's check each option as per the logic,

1) 11 – 1331

→ (11)³ = 1331

2) 12 – 1728

→ (12)3 = 1728

3) 16 – 4086

→ (16)³ ≠ 4086 → Doesn't follow the logic.

4) 13 – 2197

→ (13)³ = 2197

Here, we can see that only Option 3 doesn't follow the logic.

Hence, the correct answer is "16 – 4086".

According to the given diagram the total number of people who are good at exactly two sports are shown below :

Thus, as marked above :-

Total number of people who are good at exactly two sports = Total number of people good at both chess and badminton + Total number of people good at both chess and tennis + Total number of people good at both tennis and badminton

Total number of people who are good at exactly two sports = 14 + 11 + 18

Total number of people who are good at exactly two sports = 43

Hence, "43" is the correct answer.

The total ages of Sweta, Damini and Supriya is 56 years.

Let, the total of their ages 3 years ago be x.

→ (Shweta - 3) + (Damini - 3) + (Supriya - 3) = x

→ (Shweta + Damini + Supriya) - 9 = x

→ 56 - 9 = x

→ 47 = x

Hence, the correct answer is "47".

The logic followed here is:

Logic: Second Number = (First Number) × 2

→ Third Number = (Second Number) × 3

(12, 24, 72):

→ 24 = 12 × 2

→ 72 = 24 × 3

(14, 28, 84):

→ 28 = 14 × 2

→ 84 = 28 × 3

Let's check each option as per the logic,

1) (20, 40, 160):

→ 40 = 20 × 2

→ 160 ≠ 40 × 3 

2) (24, 72, 216):

→ 72 ≠ 24 × 2

3) (16, 32, 96):

→ 32 = 16 × 2

→ 96 = 32 × 3 ⇒ Follow the logic.

4) (18, 36, 118):

→ 36 = 18 × 2

→ 118 ≠ 36 × 3

Here, we can see that only Option 3 follow the logic.

Hence, the correct answer is "(16, 32, 96)".

Let's check each option,

When the paper is unfolded, the image we get is shown below:

Hence, the correct answer is "Option 1".

After interchanging 5 and 7, the equations we get:

I. 4 × 5 + 8 ÷ 2 – 7 = 14

→ 4 × 5 + 4 – 7 = 14

→ 20 + 4 – 7 = 14

→ 24 – 7 = 14

→ 17 ≠ 14

→ LHS ≠ RHS

II. 5 + 6 × 4 – 7 ÷ 3 = 22

→ 5 + 6 × 4 – 7/3 = 22

→ 5 + 24 – 7/3 = 22

→ 29 – 7/3 = 22

→ 80/3 ≠ 22

→ LHS ≠ RHS

Here, we can see that both equations are incorrect.

Hence, the correct answer is "Neither I nor II".

Additional Information

• Boyle's Law:
• Boyle's law states that, at a constant temperature, the volume of a given amount of gas is inversely proportional to its pressure.
• In other words, as the pressure of a gas increases, its volume decreases, and vice versa, provided the temperature remains constant. Mathematically, Boyle's law can be expressed as:
• P₁V₁ = P₂V₂
• where P₁ and V₁ are the initial pressure and volume, and P₂ and V₂ are the final pressure and volume, respectively.
• Charles's Law:
• Charles's law states that, at a constant pressure, the volume of a given amount of gas is directly proportional to its absolute temperature. This means that as the temperature of a gas increases, its volume also increases, and as the temperature decreases, its volume decreases, as long as the pressure remains constant. Mathematically, Charles's law can be expressed as:
• V₁/T₁ = V₂/T₂
• where V₁ and T₁ are the initial volume and temperature (in Kelvin), and V₂ and T₂ are the final volume and temperature, respectively.
• Avogadro's Law:
• Avogadro's law states that, at a constant temperature and pressure, equal volumes of gases contain an equal number of particles (atoms, molecules, or ions).
• This law implies that the volume of a gas is directly proportional to the number of moles of gas present. Mathematically, Avogadro's law can be expressed as:
• V₁/n₁ = V₂/n₂

where V₁ and n₁ are the initial volume and number of moles, and V₂ and n₂ are the final volume and number of moles, respectively.

Correct Answer Sound can travel through vacuum

**Key Points:**Concept:

• A sound is a form of energy that produces the sensation of hearing in our ears.
• Sound is a type of longitudinal wave.
• Sound is measured in Decibels(Db).
• The speed of the sound varies in different mediums.

Explanation:

• Sound from a violin and a flute played at the same time travel at the same speed.
• Both sounds travel through the same medium which is air.
• Both the sounds travel through at the same speed at the same time but the sound we receive are different due to characteristics associated with the sound such as pitch and amplitude.
• Hence, option 1 is correct.
• Two sound waves of the same intensity would not be perceived to have the same loudness because of the human's ear tendency to amplify sounds having frequencies in the range from 10kHz to 50kHz, sounds with these intensities seem louder to the human ear. Hence, option 2 is incorrect.
• Speed of sound in hot air is more than that of the room temperature because heat makes air molecules move around faster. Hence, option 3 is correct.
• The speed of sound depends on the density of the material.
• Tightly packed material molecules transfer the sound at high speed.
• Speed of sound is fastest in Solids, Liquids then Gas.

Thus, the incorrect statement is that two sound waves of the same intensity will always have equal loudness. 

Important PointsAmplitude:

• Amplitude is the measure of compression or rarefaction of particles of a medium through which sound is traveling.
• The higher the amplitude, the louder the sound.
• The amplitude A is related to loudness as loudness ∝ A2

Frequency:

• Frequency refers to the rate of vibration of sound.
• The pitch of a sound is decided by the measure of frequency.
• The higher the frequency, the shriller the sound.
• Frequency measured in Hertz (Hz).

Additional Information Sound in the air: 

• In a gas-like air, the particles are generally far apart so they travel further before they bump into one another.
• There is not much resistance to movement so it doesn’t take much to start a wave, but it won’t travel as fast.

Sound in water:

• In water, the particles are much closer together, and they can quickly transmit vibrational energy from one particle to the next.
• This means that the sound wave travels over four times faster than it would in the air, but it takes a lot of energy to start the vibration.

Sound in solids: 

• In a solid, the particles are even closer together and linked by chemical bonds so the wave travels even faster than it does in either liquid or air, but you need quite a lot of energy to start the wave at the beginning.

Correct Answer Budding

Key PointsAsexual Reproduction: In asexual reproduction, plants can give rise to new plants without seeds

1. Fragmentation: Where the body of the organism breaks into smaller pieces, called fragments and each segment grows into an adult individual. like Algae etc.
2. Vegetative propagation: It is a type of asexual reproduction in which new plants are produced from roots, stems, leaves, and buds. Since reproduction is through the vegetative parts of the plant, it is known as vegetative propagation. Ex- sweet potato, ginger, grass, etc.
3. Spore formation: Reproduction in fungus/fungi and Chlamydomonas.
4. Budding: The small bulb-like projection coming out from the yeast cell is called a bud. The bud gradually grows and gets detached from the parent cell and forms a new yeast cell. Ex-yeast, sponges, and hydra.

Hence, it can be concluded that Budding is the correct option.

Shortcut Trick

Assume the numbers are 10 units and 13 units.

80% of 10 units = 8 units.

8 units = 16 ⇒ 1 unit = 2.

The second number = 13 units × 2 = 26.

50% of the second number = 26 ÷ 2 = 13.

∴ The correct answer is 13.

Alternate Method

Given:

Ratio of two numbers = 10 : 13

80% of the first number = 16

Formula used:

Percentage Value = (Percentage/100) × Number

Let the first and second numbers be 10x and 13x respectively.

According to the question:

⇒ 80% of 10x = 16

⇒ (80/100) × 10x = 16

⇒ 8x = 16

⇒ x = 16 ÷ 8

⇒ x = 2

Now, find the second number:

⇒ Second number = 13x = 13 × 2 = 26

Finally, calculate 50% of the second number:

⇒ 50% of 26 = (50/100) × 26

⇒ 0.5 × 26 = 13

∴ The correct answer is 13.

Additional Information

Concept of Ratio Multiplier

When numbers are in ratio a : b, they can be expressed as ax and bx, where x is the common hcf or multiplier.

Shortcut Trick

Original Simple Interest = 4960 − 4000 = Rs. 960

Since Simple Interest is directly proportional to the rate, New Interest = 1.5 × 960 = Rs. 1440

New Amount = Principal + New Interest = 4000 + 1440 = Rs. 5440

∴ The correct answer is Rs. 5,440.

Alternate Method

Given:

Principal (P) = Rs. 4000

Original Amount (A) = Rs. 4960

Time (T) = 4 years

Formula Used:

Simple Interest (SI) = (P × R × T) ÷ 100

Amount = Principal + SI

P = Rs. 4000

SI = Rs. 960 Rate = R%

SI = Rs. 1440 Rate = 1.5R%

A = Rs. 5440

Direct proportionality: SI ∝ Rate

Calculations:

⇒ Original SI = Amount − Principal = 4960 − 4000 = Rs. 960

⇒ 960 = (4000 × R × 4) ÷ 100

⇒ 960 = 160 × R

⇒ R = 960 ÷ 160 = 6%

⇒ New Rate = 1.5 × 6% = 9%

⇒ New SI = (4000 × 9 × 4) ÷ 100

⇒ New SI = 40 × 36 = Rs. 1440

⇒ New Amount = P + New SI = 4000 + 1440 = Rs. 5440

∴ The correct answer is Rs. 5,440.

Additional Information

Simple Interest Formula

SI = (P × R × T) ÷ 100, where P is Principal, R is Rate of Interest, and T is Time. The total amount A is calculated as A = P + SI.

Direct Proportionality in SI

Since SI is directly proportional to Rate (R), if Principal and Time remain constant, increasing the rate by a factor of n will increase the simple interest by the exact same factor n.

Compound Interest vs Simple Interest

Simple interest remains constant for each successive year, whereas compound interest increases every year because it is calculated on the updated amount (Principal + previous Interest).

Shortcut Trick

Efficiency ratio (Initial : New) = 100% : 80% = 5 : 4

Time is inversely proportional to efficiency: Time ratio = 4 : 5

Given: 4 units of time = 20 days

1 unit = 20 ÷ 4 = 5 days

New time = 5 units = 5 × 5 = 25 days

∴ The correct answer is 25 days.

Alternate Method

Given: Initial time = 20 days, Efficiency decrease = 20%.

Formula Used: Total Work = Efficiency × Time

⇒ Let the initial efficiency of A be 100 units/day.

⇒ Total Work = Efficiency × Time = 100 × 20 = 2000 units.

⇒ New efficiency of A = 100 − (20% of 100) = 80 units/day.

⇒ New Time taken = Total Work ÷ New Efficiency

⇒ New Time = 2000 ÷ 80 = 25 days.

∴ The correct answer is 25 days.

Additional Information

Inverse Proportion in Work

When Total Work is constant, the time required to complete the work is inversely proportional to the efficiency (T ∝ 1/E).

Percentage and Time

If efficiency increases by x%, the new time is T ÷ (1 + x/100). If efficiency decreases by x%, the new time is T ÷ (1 − x/100).

Work Equivalence Formula

M₁D₁H₁/W₁ = M₂D₂H₂/W₂, where M is efficiency/number of workers, D is days, H is hours, and W is work.

• "Been" is the past participle of "be" and is typically used in the perfect tenses.
• Here, the present simple tense is appropriate, so we should use the base form of the verb "be".

Therefore, the correct sentence should be: "Personal care products can also be made from agricultural ingredients, such as flower or fruit extracts and oils."

The correct answer is 'Option 4' i.e. 'Deed'.

Key Points

• A "deed" in this context refers to an action or a task.
• When referring to a "good deed," we're discussing a beneficial, kind, or helpful act that one person does for another.
• This aligns best with the overall meaning of the sentence which suggests a single beneficial action making a significant impact on both the performer and the recipient of the action.

Therefore, the correct sentence is: 'Sometimes, even one good deed can make a big impact on both the person doing it and the person receiving it.

Additional Information

• Let's explain all the options:
• Deal: In this context, a "deal" would usually refer to a business agreement or transaction. It doesn't fit well in this sentence as it doesn't convey the intended meaning of a beneficial action performed for someone else.
• Dwell: "Dwell" primarily means to live in a specified place or to think, speak, or write at length about a particular subject, especially one that is a source of unhappiness, anxiety, or dissatisfaction. It does not fit in this context.
• Drill: In this context, a "drill" would refer to a training exercise or a tool for making holes. Neither of these meanings fits well in this sentence.

Additional Information

• MALIGNANT: This is the correctly spelled word. "Malignant" means very dangerous or harmful, or refers to a disease, like cancer, that is likely to get worse and lead to death.(हानिकारक)

The correct answer is 'Option 3' i.e. 'Flounder'.

Key Points

• Here's the rationale:
• D. The wheels rotated on a fixed axle linked by a shaft to the yoke.

• C. The chassis of the two carts are made of wood and covered with thick copper sheets.
• This sentence follows nicely from D, further describing the construction of the carts and the materials used.
• B. The wheels are decorated with triangles made of copper.
• After discussing the materials of the carts, it's appropriate to move on to the decoration of the wheels.
• A. The triangles are distributed in three concentric circles.
• Finally, this sentence goes into more specific detail about the decoration mentioned in B, closing the paragraph nicely by describing how the triangles are arranged.

Therefore, the correct sequence is DCBA: "The wheels rotated on a fixed axle linked by a shaft to the yoke. The chassis of the two carts are made of wood and covered with thick copper sheets.

• So when we say "The machine can be set to deliver a certain number of coins", we mean that the machine can be adjusted or programmed to deliver a specific amount of coins.

Additional Information

• Here's why the other options are incorrect:
• "Sums": This verb is used in the context of adding up numbers or amounts. It doesn't make sense in this context.
• "Expands": This verb means to increase in size, volume, quantity, or scope. It doesn't make sense to say the sun "expands" in the east.
• "Elevates": This verb means to raise or lift something up to a higher position. While the sun does appear to move higher in the sky after sunrise, the standard term used to describe this phenomenon is "rise", not "elevate".

The correct answer is 'Option 1'.

Key Points

• The correct sequence of the sentences to form a meaningful and grammatically correct paragraph is 1) PQRS.
• Here's the rationale:
• P. The Spanish flu, also known as the 1918 flu pandemic, was a deadly pandemic in recent history.
• This sentence should come first as it introduces the subject, which is the Spanish flu.
• Q. It spread worldwide during the year 1918-1919.
• This sentence logically follows P, providing information about when and where the Spanish flu spread.
• R. The virus infected 500 million people – about a third of the world's population at the time.
• After stating when and where the flu spread, this sentence gives specifics about how many people were affected, providing additional information about the severity of the Spanish flu.
• S. The death toll was estimated to be at least 50 million worldwide, possibly as high as 100 million this makes it the severest pandemic in human history.
• Finally, this sentence further underscores the severity of the Spanish flu by discussing the death toll, which makes it a fitting conclusion to the paragraph.

Therefore, the correct sequence is PQRS: "The Spanish flu, also known as the 1918 flu pandemic, was a deadly pandemic in recent history. It spread worldwide during the year 1918-1919. The virus infected 500 million people – about a third of the world's population at the time. The death toll was estimated to be at least 50 million worldwide, possibly as high as 100 million this makes it the severest pandemic in human history."
