SSC CHSL Previous Paper 16 (Held On: 11 March 2018 Shift 1) (Previous Year Paper)

The correct answer is 'recuperate'

Key Points

• The meaning of the given word 'recuperate' is 'recover from illness or exertion'
• Let's see the word in the given sentence-
• I went away to the country to recuperate.

The correct answer is 'ABC' 

Key Points

• The last word of the fixed sentence is 'an' hence the next word should have a sound of vowel and this word we can see in sentence A
• Hence, after looking at the options we can directly say that the answer is 'option 1'

So the correct sentence is- Finally, what is left are an innocuous bunch of audit queries, useful for auditors and harmless for the staff member.

The correct answer is 'No improvement'

Key Points

The given underlined phrase doesn't need any improvement.

• According to grammar, the present perfect tense is used to tell when the situation is happened and still continuing in the present.
• Let's see the given options-
• 'has becoming' is incorrect because 'with has we can't write 'becoming' which is -ing form of the verb.'
• 'have become' is incorrect because with the singular noun we need to use the singular verb. In the given sentence, the subject is 'cooking' which is singular in number.
• So the given phrase doesn't need any improvement.

So the correct sentence- Needless to say, cooking has become easier now.

The correct answer is 'No improvement'

Key Points

• In the given sentence, the usage of 'had been hijacked' is correct.
• We need a passive voice in the sentence to show that the doer of hijacking is somebody else's.
• Let's see the options-
• 'have been hijacked' we can't write 'have' with the singular subject because the noun 'footpath' is singular.
• 'have being hijacked' we can't write the -ing form of the verb with 'have' hence it is incorrect.
• 'Had been hijacking' as it is already stated that we need a passive voice and the structure of the passive voice is 'been +V3' hence this option is also incorrect.

So the correct sentence is- The footpath had been hijacked by gigantic blue-and-green barricades.

The correct answer is 'The Queen asked whether he really came from Spain'

Key Points

• Let's see the following steps to change the Direct speech to Indirect speech-
• Firstly, see the type of sentence. The given sentence is an imperative sentence and interrogative sentence because the reported speech starts with a verb i.e. 'do' also at the end of the sentence we have a question mark.
• Secondly, see the tense of the verb the given sentence is in the present tense.
• Thirdly, if we have a question mark in the sentence then we have to use 'if/whether' in the indirect speech.
• So after following these steps the correct indirect speech is- The Queen asked whether he really came from Spain.

The correct answer is 'Disintegrate'

Key Points

• The meanings of the words are:
• Disintegrate →divide into small parts
• Juxtapose → place side by side
• Conjugate → coupled; connected
• Entwine →wound

So according to the meanings of the given words, the correct answer is 'Disintegrate'

The correct answer is 'Pander'.

Key Points

• Let's see the meanings of the words are:
• Depress→ make sad
• Example: The ongoing bad news about the economy tends to depress a lot of people.
• Frustrate→ prevent (a plan or attempted action) from progressing, succeeding, or being fulfilled.
• Example: It frustrates me when my internet connection is slow and I can't get my work done on time.
• Offend → to annoy
• Example: The comedian's racially insensitive joke offended many in the audience.
• Pander → gratify or indulge (an immoral or distasteful desire or taste or a person with such a desire or taste).
• Example: The politician's promises to lower taxes without outlining any feasible plan seemed like an attempt to pander to the voters.

So according to the meaning of the given words, the correct answer is 'Pander'.

The correct answer is 'A profound or notable transformation'

Key Points

• The meaning of the given idiom 'A sea change' is a complete change in someone's attitudes or behavior'
• Let's see an example-
• They are also part of a sea change in the capital's hotel industry.

The correct answer is 'Apprehend someone in the course of wrongdoing'

Key Points

• The meaning of the given idiom 'Catch red-handed' is 'they are caught while they are in the act of doing something wrong.'
• Let's see an example-
• My friend and I robbed a store and were caught red-handed.

The correct answer is 'by'

Key Points

• According to grammar, 'by' preposition is used 'to tell 'through the agency or means of' hence, in the given sentence we need to tell how it is going to be 'used'
• So the correct sentence is- This function is used by the active, wide-awake.

The correct answer is 'not'

Key Points

• According to parts of speech, 'not' is an adverb and 'no' is an adjective.
• In the given blank, we need 'not' which is qualifying the prepositional phrase 'in harmony'
• We can't use the 'do not' because we don't need a helping verb in the blank. Hence, 'not' is the correct answer.

The correct answer is 'from'

Key Points

• According to grammar, the meaning of the word 'banish' is 'to send someone away, especially from their country, and not allow them to come back'
• We use the prepositions 'to' and 'from' with this verb.
• Let's see the concept of 'to and from'
• Banish to- we use the preposition 'to' when we are sending someone from somewhere.
• He was banished to an uninhabited island for a year.
• Banish from- we use the preposition 'from' when the meaning of the word is 'to get rid of something completely'
• Try to banish all thoughts of revenge from your mind.

So according to the meaning given the correct answer is 'banish from'

The correct answer is 'On'

Key Points

• According to grammar, 'focus on' is a phrasal verb that means 'to give most of your attention to someone or something'
• Let's see an example-
• Try to focus on the most important facts.

So the correct sentence is- the mind on some mental

The correct answer is 'performs'

Key Points

In the given blank, we need to fill 'performs'

• According to grammar, whenever the subject of the sentence is singular then the verb should be singular.
• Hence, in the sentence, the subject is 'function' which is singular, and in the options, there is only one singular verb which is 'performs'

So the correct sentence is- The action function performs the volitional.

The correct answer is 'Exhilarate'

Key Points

• The correct spelling is 'Exhilarate'
• Let's see the meaning of the given word- to give someone strong feelings of happiness and excitement
• Let's see an example-
• Its effect is an exhilarating regression that undoes the vestments of selfhood.

The correct answer is 'A very remarkable observation was made by her.'

Key Points

• Let's see the following steps while changing the Active voice into the passive voice-
• Firstly, see the tense of the sentence because the tense in the active voice and the passive voice doesn't change.
• Secondly, see whether the sentence has an object. If it doesn't have the object look for the infinitive verb and make the passive of the infinitive verb.
• Thirdly, the subject of the active voice changes into the object of the sentence in the passive voice, and the object becomes the subject of the sentence.
• So following these steps we get the correct passive voice which is- A very remarkable observation was made by her.

The correct answer is 'PQR'

Key Points

• In the fixed sentence there is a usage of 'are' which is a helping verb hence we need to write the main verb after it which is given in sentence P.
• In sentence Q, 'resources' is the object complement for the object 'groundwater' hence according to grammar this part will be the second one.
• So according to this pairing the correct answer is 'PQR'

The correct answer is 'Definite'

Key Points

• Let's see the meaning of the given words-
• Moot→ Subject to debate or dispute.

• Dumb→ means 'unable to speak'
• So according to the meaning, the correct synonym is 'clear'

The correct answer is 'Overstatement'.

Key Points

• The best option that expresses the meaning of the given word "Hyperbole" is option 2, "Overstatement."
• The word "Hyperbole" refers to an exaggerated statement or claim that is not meant to be taken literally, usually used for emphasis or effect.
• For example, "He is so hungry that he could eat a horse" is a hyperbole because it exaggerates the degree of hunger to make a point.
• Overstatement refers to the act of exaggerating something beyond its actual significance or importance. It is a type of hyperbole that is used to emphasize a point or to make something appear more impressive or dramatic.
• Example of overstatement: "I've been waiting for ages." - In this sentence, the speaker is using overstatement to exaggerate the amount of time they've been waiting. They may not have actually been waiting for a very long time, but they want to emphasize their impatience.
• Option 1, "Spoliation," refers to the act of plundering or looting, and is not related to the meaning of "Hyperbole."
• For example, "The invaders engaged in spoliation of the city's treasures" means that the invaders looted the city's treasures.
• Option 3, "Simplification," refers to the process of making something simpler or easier to understand, and is not related to the meaning of "Hyperbole."
• For example, "She simplified the instructions for the children to follow" means that she made the instructions easier to understand for the children.
• Option 4, "Injury," refers to physical harm or damage caused to a person or object, and is not related to the meaning of "Hyperbole."
• For example, "He suffered a severe injury to his leg in the accident" means that he suffered physical harm to his leg.
• Therefore, the correct answer is option 2, "Overstatement," which accurately expresses the meaning of "Hyperbole."

The correct answer is 'determines'

Key Points

• In the given blank, we need a verb 'determines'
• According to grammar, when the subject of the sentence is singular we need a singular verb for it.
• The subject in the given sentence is 'Career' which is singular in number so the correct verb for this is 'determines'
• The meaning of the word 'determine' is 'cause to occur in a particular way'

So the correct sentence is- Career determines the kind of lifestyle one will lead and his/her position in the society.

The correct answer is 'bare'

Key Points

• Let's see the meaning of the given words-
• Bare→ means 'uncover and expose it to view'
• Bear→ means 'carry or convey'
• Beer→ means 'an alcoholic drink made from yeast-fermented malt flavored with hops'
• Bee→ means 'an insect of a large group'
• Hence, according to grammar, we need a verb in the given blank and contextually the correct verb is 'bare'

The correct answer is '3' i.e. error lies in the third part of the sentence

Key Points

In the third part of the sentence, the usage of 'developmental' is incorrect Instead, use 'development'

• According to grammar, whenever two nouns/verbs/adjectives are connected with the conjunction 'and' then they should be in the same form.
• Hence, 'democracy' is the noun and development is a noun too.
• 'Developmental' is an adjective that is incorrect.

So the correct sentence is- We wish to make globalization a means to expand human well being and freedom, and to bring democracy and development to local communities where people live.

The correct answer is '1' i.e. error lies in the first part of the sentence.

Key Points

In the first part of the sentence, the usage of 'were' is incorrect Instead, use 'was'

• According to grammar, whenever the subject of the sentence is singular then, the verb of the subject is always singular.
• In the given sentence, the subject of the sentence is 'person' that is singular hence use the singular verb for it.

So the correct sentence is- The person was duly rewarded for her bravery.

3. 22, 69, 11, 75 → H, S, B, U

4. 14, 87, 32, 67 → H, T, B, X

Hence, the correct answer is ‘42, 44, 14, 97’.

Concept used:

Laws of Indices:

1. a^m × aⁿ = a^{{m + n}}
2. a^m ÷ aⁿ = a^{{m - n}}
3. (a^m )ⁿ = a^mn
4. (a)^-m = 1/a^m
5. (a)^m/n = ⁿ√a^m
6. (a)⁰ = 1

Calculation:

⇒ 5¹² × 125 ÷ 15625 = 3125 × 25^?

⇒ 5¹² × 5³ ÷ 5⁶ = 5⁵ × (5²)^?

⇒ 5^{12 + 3 - 6} = 5^{5 +} 2?

⇒ 5⁹ = 5^{5 +} 2?

⇒ 9 = 5 + 2?

⇒ ? = 4/2

∴ ? = 2

Calculation:

Let the two parts be ‘x’ and ‘(150 – x)’

Sum of their reciprocals = 3/112

⇒ 1/x + 1/(150 – x) = 3/112

⇒ (150 – x + x)/x(150 – x) = 3/112

⇒ 150/x(150 – x) = 3/112

⇒ 150 × 112/3 = x(150 – x)

⇒ 5600 = 150x – x²

⇒ x² – 150x + 5600 = 0

⇒ x² – 70x – 80x + 5600 = 0

⇒ x(x – 70) – 80(x – 70) = 0

⇒ (x – 70)(x – 80) = 0

⇒ x = 70, 80

∴ The two parts are 70 and 80

Calculation:

We can write,

⇒ 108 = 2² × 3² × 3

⇒ √108 = 2 × 3 × √3 = 6√3

Hence,

⇒ (5√3)/2 + 6√3

= √3(5/2 + 6)

= 17√3/2

∴ value of $\frac{{5\sqrt 3 }}{2} + \sqrt {108}$  is 17√3/2

Calculation:

∵ (a – 1/a)² = a² + 1/a² – 2

⇒ (a – 1/a)² = 38 – 2 = 36

⇒ (a – 1/a) = √36

∴ (a – 1/a) = 6

Calculation:

When two tangents are drawn to a circle from an external point, then the tangent segments are equal,

This means, in the given figure, AP = AQ

∵ OP = OQ = radius of the circle

Hence, the two triangles AOP and AOQ are equal triangles

∴ ∠AOP = ∠AOQ

Calculation:

For an equilateral triangle with side ‘a’ units, length of inradius = a√3/6 units

Given, the side of the equilateral triangle = 8√3 cm

Length of inradius = 8√3 × √3/6

= 24/6

= 4 cm

∴ The length of the inradius  is 4 cm

Calculation:

If the current population of a town is P and it increases at a rate of R% per annum, then,

Population after n years = P × (1 + R/100)²

Given, P = 350000, R = 20%,

∴ Population after 2 years = 350000 × (1 + 20/100)² = 350000 × 1.44 = 504000

Calculation:

Let the incomes of P and Q be Rs. ‘4x’ and Rs. ‘7x’ respectively

Let the expenditures of P and Q be Rs. ‘3y’ and Rs. ‘7y’ respectively

Now, Savings = Income – Expenditure

⇒ Savings of P = 4x –3y = 10000      ----(1)

⇒ Savings of Q = 7x – 7y = 7000

⇒ x – y = 1000

⇒ y = x – 1000

Substituting in (1),

⇒ 4x – 3(x – 1000) = 10000

⇒ 4x – 3x + 3000 = 10000

⇒ x = 10000 – 3000 = 7000

∴ Income of P = 4x = 4(7000) = Rs. 28000

GIVEN:

Investment of Akash = Rs. 85000

Investment of Payal = Rs. 102000

Profit is divided among them in the ratio of 1: 1

CALCULATION:

Akash’s total capital investment = 85000 × 12 = 1020000

Let Payal join Akash after ‘x’ months

⇒ Payal’s investment time = (12 – x)

⇒ Payal’s total capital investment = 102000 × (12 – x)

Now, the Ratio of profits = Ratio of total capital investments

⇒ 1∶ 1 = 1020000∶ [102000(12 – x)]

⇒ 102000(12 – x) = 1020000

⇒ 12 – x = 10

⇒ x = 12 – 10 = 2

∴ Payal joined after 2 months

Shortcut Trick Profit ratio = Investment × time

P_A/P_B = I₁T₁/I₂T₂

1/1 =  (85000 × 12)/1020000 T₂

T₂ = 10 so Payal joined after 2 month

Calculation:

As we know, all the one-digit, two-digit, and 3-digit natural numbers are from 1 – 999

∵ Sum of n natural numbers = n(n + 1)/2

Sum of 999 natural numbers = (999 × 1000)/2

= 499500

∴ Required average = 499500/999 = 500

Short Trick:

Interest for 7 years = Rs. 8400

∴ Interest for 1 year = 8400/7 = Rs. 1200

Rate of interest = Interest/Principle = 1200/6000 × 100 = 20%

Detailed Solution:

Let the rate of interest be R%

As we know, Simple interest = (Principal × Rate × Time)/100

Given, Principal = Rs. 6000

Simple interest for 7 years = (6000 × R × 7)/100

⇒ 8400 = 420R

⇒ R = 8400/420 = 20%

∴ Rate of interest = 20% p.a.

Cost price = Rs. 13400

Loss = 4% of 13400 = 4/100 × 13400 = Rs. 536

∵ Selling price = Cost price – Loss

∴ Selling price = 13400 – 536 = Rs. 12864

Calculation:

Selling price = (20/31) × Marked price(MP)

Now, Cost price – Loss = Selling price

⇒ CP – 20% of CP = (20/31) × MP

⇒ 80% of CP = (20/31) × MP

⇒ 4/5 × CP = 20/31 × MP

⇒ MP/CP = 4/5 × 31/20 = 31/25

∴ Ratio of marked price and cost price = 31 ∶ 25

Calculation:

We can write,

⇒ √128 = √(2⁶ × 2) = 2³√2 = 8√2

⇒ √72 = √(2² × 3² × 2) = 2 × 3√2 = 6√2

⇒ √32 = √(2⁴ × 2) = 2² × √2 = 4√2

Hence,

⇒ (√128 + √72)/√32

= (8√2 + 6√2)/4√2

= 14√2/4√2

= 7/2

= 3.5

Calculation:

Let the tank be filled in ‘a’ hrs.

Part filled by X in 1 hr. = 1/16

⇒ Part filled by X in a hrs. = a/16

Part filled by Y in 1 hr. = 1/20

⇒ Part filled by Y in a hrs. = a/20

Part emptied by Z in 1 hr. = 1/25

⇒ Part emptied by Z in (a – 6) hrs. = (a – 6)/25

Now, Total work done = 1

⇒ a/16 + a/20 – (a – 6)/25 = 1

⇒ a(1/16 + 1/20 – 1/25) = 1 – 6/25

⇒ a(29/400) = 19/25

⇒ a = 400/29 × 19/25

⇒ a = 304/29

∴ The tank will be filled in 304/29 hrs.

Calculation:

∵ Speed = Distance/Time

⇒ Speed of man = 700/120 = 35/6 m/sec.

∴ Speed of man = 35/6 × 18/5 = 21 km/hr.

No. of deaths in 2012 = 8000

No. of deaths in 2013 = 500

No. of deaths in 2014 = 4500

No. of deaths in 2015 = 7000

∴ No. of deaths were lesser in 2013 than the previous year

No. of deaths in 2017 = 2500

No. of deaths in 2013 = 500

∴ Required difference = 2500 – 500 = 2000

No. of deaths in 2012 = 8000

No. of deaths in 2016 = 5000

Difference = 8000 – 5000 = 3000

∴ The no. of deaths in 2016 were lesser than that in 2012 by 3000/8000 = 0.375

No. of deaths in 2013 = 500

Average insurance paid for each death = Rs. 20 lakhs

∴ Total insurance paid in 2013 = 500 × 20 lakhs = Rs. 10000 lakhs = Rs. 100 crores

Given:

Area of rectangle = 60 cm²

Breadth of rectangle = 5 cm 

Concept used:

Area of rectangle = Length × Breadth

Calculations:

Area of rectangle = Length × Breadth

⇒ 60 = Length × 5

⇒ Length = 60/5 = 12 cm

⇒ Diagonal of rectangle = √(length² + breadth²)

⇒ Diagonal of rectangle = √(144 + 25) = √169 = 13 cm

∴ Diagonal of rectangle is 13 cm.

Calculation:

Area of the circle with radius ‘r’ = πr²

⇒ 22/7 × r² = 616

⇒ r² = 196

⇒ r = √196 = 14 cm

∴ Circumference of circle = 2πr = 2 × 22/7 × 14 = 88 cm

Calculation:

The total surface area of a hemisphere of radius ‘r’ = 3πr2

The curved surface area of a hemisphere of radius ‘r’ = 2πr²

Radius of hemisphere = 42/2 = 21 cm

∴ Curved surface area of given hemisphere = 2 × 22/7 × 21 × 21 = 2772 cm²

Calculation:

 tan 60° + 1/3

= √3 + 1/3                                [∵ tan 60° = √3]

= (3√3 + 1)/3

Calculation:

In the given ∆PQR,

⇒ cos P = adjacent/hypotenuse = PQ/PR = 3/5

⇒ sin P = opposite/hypotenuse = QR/PR

But, sin P = √(1 – cos² P) = √(1 – 9/25) = √(16/25) = 4/5

⇒ QR/PR = 4/5

Now, cos R = adjacent/hypotenuse = QR/PR

∴ cos R = 4/5

The correct answer is Only women.

EXPLANATION:

• Women have a perfect pair of sex chromosomes XX while men have a mismatched pair in which one is a normal-sized X and the other a short one Y which is XY.

Key Points

• Chromosomes are structures found in the center (nucleus) of cells that carry long pieces of DNA. DNA is the material that holds genes. It is the building block of the human body.
• Chromosomes also contain proteins that help DNA exist in the proper form.
• Chromosomes come in pairs.
• Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes).
• Half comes from the mother, the other half comes from the father.
• Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born. They are called sex chromosomes:
• Females have 2 X chromosomes.
• Males have 1 X and 1 Y chromosome.
• The mother gives an X chromosome to the child. The father may contribute an X or a Y. The chromosome from the father determines if the baby is born male or female.
• A human being has 23 pairs of chromosomes in which one pair of X and Y chromosomes determine the sex of the human being.
• If there is one X chromosome from the mother and one X chromosome from the father, then two X chromosomes (XX) make a girl whereas the X chromosome from the mother and Y chromosome from the father then these chromosomes (XY) make a boy.
• The remaining chromosomes are called autosomal chromosomes.
• They are known as chromosome pairs 1 through 22.

CONCEPT:

• Momentum (p): The momentum of a body is the product of its mass and velocity.
• It is a vector quantity.
• The SI unit of momentum is kg.m/s.

Momentum (p) = Mass (m) × Velocity (v)

CALCULATION:

Given that:

mass =18 and v = 6

Momentum (p) = m × v = 18 × 6 = 108 kg.m/s

The Correct answer is Force.

Explanation:

• A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects.
• Newton’s Second law of motion: The rate of change of momentum of any object is directly proportional to the applied force on the body.

${\rm{Force;}}\left( {\rm{F}} \right) = \frac{{{\rm{Δ }}P}}{{{\rm{Δ }}t}}$

Where Δ P = Change in momentum and Δ t = change in time taken

Additional Information

1. Impulse (J): The change in momentum is called impulse.
2. Torque/moment/moment of force/rotational force/turning effect is the rotational equivalent of linear force.
3. Newton’s Second Law of Motion states that the rate of change of linear momentum of a body is proportional to the force acting on it. So option 3 is correct.
4. The kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
