SSC CHSL Previous Paper 17 (Held On: 9 Jul 2019 Shift 1) (Previous Year Paper)

The correct answer is option 1 i.e. regarded.

regarded- consider or think of in a specified way.

reviewed- assess (something) formally with the intention of instituting change if necessary.

referred- mention or allude to.

repeated- done or occurring again several times in the same way.

Here, regarded is the right option contextually.

So, the chosen option is correct.

The correct answer is option is 4 i.e. of.

Whenever we have to show relation or a sense of belonging we use OF.

As here we are showing the relation of the firm with the value, we have to use OF in the given blank.

So, the chosen answer is correct.

The correct answer is option 3 i.e. Every.

As is clear from the meaning of the passage, the core of the business is value proposition, and this policy is applicable to all the businesses.

This meaning can be imparted by only one of the options that is option 3.

So the chosen option is correct.

The correct answer is 1 i.e. Always.

Only an adverb can take that place and among the options, we have only two adverbs always and even.

Contextually, option 1 suits the given blank space.

The correct answer is option 1 i.e. The.

'Those' and 'this' will not be the answer as these are pronouns and refer to nouns mentioned previously. But there are no mentions of the promoters and the managers in the previous sentences.

'There' will not be the answer as it is an adverb.

Option 1 i.e. 'the' suits the blank space grammatically and contextually.

The correct answer is option 4 i.e. humble.

ARROGANT- having or revealing an exaggerated sense of one's own importance or abilities.

rough- having an uneven or irregular surface; not smooth or level.

uncouth- lacking good manners, refinement, or grace.

bold- (of a person, action, or idea) showing a willingness to take risks; confident and courageous.

humble- having or showing a modest or low estimate of one's importance.

Based on the mention meaning it can be said that only option 4 coveys the opposite meaning of the given word.

The correct answer is option 2 i.e. avoiding too much closeness.

The meaning of the given idiom is- away from the body, with one's arm fully extended.

The meaning of the idiom conveys the same meaning as written in option 2.

The correct answer is option 2 i.e. I'm afraid I do not know.

The verb Know never comes in the continuous form of the verb as it is verb of perception.

We need to keep it in other form of the verb for making the use correct.

Option 2 improves the sentence grammatically and contextually.

The correct answer is option 2 i.e. receipt.

receipt- the action of receiving something or the fact of its being received.

The correct answer is option 4 i.e. Maxim.

Look at the meaning of the given options:

• parable- a simple story used to illustrate a moral or spiritual lesson, as told by Jesus in the Gospels.
• illustration- a picture illustrating a book, newspaper, etc.
• instance- an example or single occurrence of something.
• maxim- a short, pithy statement expressing a general truth or rule of conduct.
  

Hence from the above-given meanings, we find that the correct answer is option  4 i.e. maxim.

The correct answer is option 2 i.e. deferred.

demanded- ask authoritatively or brusquely.

deferred- put off (an action or event) to a later time; postpone.

deployed- move (troops or equipment) into position for military action.

decided- (of a quality) definite; unquestionable.

Based on the meaning mentioned above only option 2 suits the passage grammatically and contextually.

The correct answer is 2 i.e. BDAC.

As A, D and C contain pronoun in it, this can not be the first sentence.

Now it is clear that sentence will start with the Option B and we have two options starting with B.

lets go ahead, After B, A can not come as there is another pronoun in the sentence  IT'S.

So, the correct option is 2.

BDAC is arrangement here.

• The correct answer is Option 3.
• The meaning of the given words:
• Quest: To seek a goal; to search for, ambitious.
• Path: A course taken, track.
• Destination: The act of destining or appointing; the place set for the end of a journey.
• Search: An attempt to find something.
• Route: A course or way.
• Therefore, out of given options the best alternative is 'Search'.

• The correct answer is Option 4 i.e. 'No improvement'.
• The given sentence is in present perfect tense which refers to an action that began at sometime in the past and is still in progress. In such cases we use 'have been + v + ing' form to represent the present perfect tense.

• The correct answer is Option 4.
• Given active sentence is in interrogative form therefore interrogative will be changed to an assertive sentence. To change the sentence into an indirect sentence. Simple past will be changed to past perfect tense, 'last month' will be changed to 'previous month'.
• Therefore, all these conditions are satisfied only in option 4.

The correct answer is Option 3

Explanation-

• The meaning of the given idiom 'acid test' - it is a situation or event which provides definitive proof of whether something is true or false, right or wrong, good or bad, effective or ineffective.
• Therefore only option 3 'definitive proof of truth or falsehood' gives the meaning of the given idiom.

The correct answer is a terrible weather.

Key Points

• The error lies in the usage of the indefinite article 'a' with an uncountable noun 'weather'.
• The word "weather" does not take the indefinite article "a" before it,
• Remove article 'a' to make the sentence grammatically correct.
  

Correct sentence: With this heatwave on, we have terrible weather.

The correct answer is Option 4.

Explanation:The meaning of the given words: 

• Advance: To promote or advantage, to move forward.
• Move: To change place or posture, to act.
• Shift: A slight movement or change.
• Progress: Movement or advancement.
• Retreat: The act of pulling back.

Therefore, out of given options only option 4 is the antonym and all other options are the synonyms of the given word.

• The correct answer is Option 1.
• In active voice, the subject performs the action denoted by the verb.
• On the other hand, a sentence is in the passive voice when the subject of the sentence is acted upon by the verb.
• When changing from active voice to passive, we do not change the tense of the given sentence.
• Except Option 1 all other options are in different tense. Therefore option 1 is the correct answer.

The correct answer is Option 2 

Look at the meaning of the given options-

• Precise: exact, accurate.
• Acronym: An abbreviation formed by the beginning letters or syllables of other words.
• Ellipsis: The omission of word or phrase.
• Epitome: A representative example, a brief summary of a text.
  

Hence from the above-given meanings, we find that the correct answer is option 2 i.e. acronym.

The correct answer is Option 2.

Explanation:The meaning of the given words:

• Orthodox: Conforming to the accepted, traditional doctrines.
• Civilized: Having a highly developed society or culture.
• Traditional: communicated from ancestors.
• Habitual: Behaving in a regular manner.
• Deliberate: Intentional, done on purpose.

Therefore, out of given options, traditional is the most similar word to the given word.

• The correct answer is Option 1.
• In the given sentence, the preposition 'as' and the pronoun 'that' are used together which is grammatically error.
• Therefore, remove 'that' to make the sentence grammatically correct.

The correct answer is Option 2.

• Sentence 'c' is the independent sentence, hence, it will be the first sentence.
• Hence, option 1 and 3 are eliminated.
• Sentence 'c' will be followed the sentence 'a' because sentence 'c' talks about a woman and sentence 'a' talks about the same woman.
• This combination is given in only option 2, hence, it will be the correct answer.

The correct answer is option 3.

When folded, the transparent sheet will look the below figure:

Hence, the correct answer is the figure in option 1.

Given that:

A + B + C = 209 ...... (i)

A = 6B ......(ii)

C = 4B .......(iii)

From (i), (ii) and (iii),

6B + B + 4B = 209

⇒11B = 209

⇒ B = 209 ÷ 11

⇒ B = 19

Therefore, A = 6 × 19 = 114

Hence, A gers 114 rupees.

3 and 6 are adjacent to 4 in the first position of the dice.

1 and 5 are adjacent to 4 in the second position of the dice.

Now, the only number left is 2.

Thus, 4 must be opposite to 2.

Hence, the number opposite to the face having 2 is 4.

Calculation:

First articles C.P. = Rs. 3000

First articles S.P. = 3000 × (115/100) = Rs. 3450.

Second articles C.P. = Rs. 3000

Second articles S.P. = 3000 × (110/100) =. Rs. 3300

Third articles C.P. = Rs. 3000

Third articles S.P. = 3000 × (85/100) = Rs. 2550

Total C.P. = 3000 × 3 = Rs. 9000

Total S.P. = 3450 + 3300 + 2550 = 9300

Profit percentage = (300/9000) × 100 = 10/3%

∴ The correct answer is 10/3%.

Shortcut Trick

Cost price is the same 

⇒ 3000(15% + 10% - 15%) = 300

Total cost price of 3 articles = 3 × 3000 = 9000

⇒ Profit percentage = (300/9000) × 100 = 10/3%

∴ The total profit gain on the article (10/3) %.

Given:

The distance between the centres (D) = 13 cm

Radius of circle = 2.5 cm

Calculation:

The length (in cm) of a transverse common tangent =√{(D)² − (R₁ + R₂)²}

⇒ √((13)² − (2.5 + 2.5)²)

⇒ √(169 − 25)

⇒ √144

⇒ 12 cm

∴ The correct answer is 12 cm

Given:

7(cosec255 - tan235)+ 2 × sin 90 - y × tan252 tan238 = y/2

Calculation:

⇒ 7(cosec²55 - tan²35)+ 2 × sin 90 - y × tan²52 tan²38 = y/2

⇒ 7(cosec255 - cot255)+ 2 × sin 90 - y × tan252 tan238 = y/2

⇒ 7 × 1 + 2 × 1 - y tan² 52 × 1/tan² 52 = y/2

⇒ 9 – y = y/2

⇒ 3y/2 = 9

⇒ y = 6

∴ The correct answer is 6.

Given:

⇒ x = 2 + √5

Formula used:

(a + b)³ = a³ + b³ + 3ab (a + b)

Calculation:

⇒ x = √5 + 2

By componendo and dividendo

⇒ 1/x = √5 - 2 

Now,

⇒ x + 1/x = 2 + √5 + √5 - 2 = 2√5

On cubing both sides,

⇒ (x + 1/x)³ = (2√5)³

⇒ x³ + (1/x³) + 3(x + 1/x) = 40√5

⇒ x³ + (1/x³) + 3(2√5) = 40√5

⇒ x³ + (1/x³) = 40√5 − 6√5

⇒ x³ + 1/x³ = 34√5

∴ The correct answer is 34√5.

Shortcut TrickConcept used:

⇒ x + 1/x = p

⇒ x3 + 1/x3 = p³ - 3p

Calculation:

⇒ x = √5 + 2

By componendo and dividendo

⇒ 1/x = √5 - 2 

Now,

⇒ x + 1/x = 2 + √5 + √5 - 2 = 2√5

⇒ x + 1/x = 2√5

⇒ x3 + 1/x3 = (2√5)³ - 3 × 2√5

⇒ x3 + 1/x3 = 40√5 - 6√5

⇒ x3 + 1/x3 = 34√5

∴ The correct answer is 34√5.

Given:

⇒ a3 - b3 = 899

⇒ a - b = 31

Formula used:

(a - b)² = a² + b² - 2ab

a3 - b3 = (a - b) (a2 + b2 + ab)

Calculation:

⇒ a³ - b³ = (a - b) × (a² + b² + ab)

⇒ a³ - b³ = (a - b) × (a² + b² + ab + 2ab - 2ab)

⇒ a³ - b³ = (a - b) × ((a² + b² - 2ab) + 3ab)

⇒ a³ - b³ = (a - b) × ((a - b)² + 3ab)

Putting the values,

⇒ (a³ - b³) / (a - b) = (a - b)² + 3ab

⇒ 899/31 = (a - b)² + 3ab

⇒ (a - b)² + 3ab = 29

∴ The correct answer is 29.

Given:

ABCD is a cyclic quadrilateral. 

∠ADC = 126°

Calculation:

∠ADC + ∠ABC = 180°(sum of the opposite angles in a cyclic quadrilateral is 180°)

∠ADC + ∠ABC = 180°

⇒ 126° + ∠ABC = 180°

⇒ 126° + ∠ABC = 180°

⇒ ∠ABC = 180 − 126°

∠ABC = 54°

Since, ∠ACB

∠ACB is an angle in a semi–circle.

∠ACB = 90°

In ΔABC, ∠BAC + ∠ACB + ∠ABC = 180°

ΔABC, ∠BAC + ∠ACB + ∠ABC = 180° [by angle sum property of a triangle]

⇒ ∠BAC = 90° + 54° = 180°

⇒ ∠BAC = 90° + 54° = 180°

⇒ ∠BAC = 180° − 144° = 36°

∴ The correct answer is 36°

Calculation:

According to the question:

Percentage change in area of rectangle

⇒ (2079/10000) × 100 = 20.79% 

∴ The correct answer is 20.79%.

Given:

△ ABC ∼ △ QPR

$\frac{ar\left( \text{ }!!\Delta!!\text{ }ABC \right)}{ar\left( \text{ }!!\Delta!!\text{ }PQR \right)}=\frac{4}{25}$

Calculation:

△ ABC ∼ △ QPR

In similar triangles, the ratio of their corresponding sides are equal:

⇒ (AC/QR)2 = $\frac{ar\left( \text{ }!!\Delta!!\text{ }ABC \right)}{ar\left( \text{ }!!\Delta!!\text{ }PQR \right)}$

⇒ (AC/QR)2 = 4/25

⇒ AC/QR = 2/5

⇒ 10/QR = 2/5

⇒ QR = 25

∴ The correct answer is 25 cm.

Given:

x4 + x-4 = 194

Formula used:

(a + b)² = a² + b² + 2ab

Calculation:

x⁴ + 1/x⁴ = 194       ----(1)

⇒ (x² + 1/x²)² – 2 = 194

⇒ (x² + 1/x²)² = 194 + 2

⇒ x² + 1/x² = √196

⇒ x² + 1/x² = 14      ----(2)

⇒ (x + 1/x)² – 2 = 14

⇒ (x + 1/x)² = 14 + 2

⇒ (x + 1/x) = √16

⇒ x + 1/x = 4

⇒ x² + 1 = 4x

⇒ x² – 4x = –1       ----(3)

We have to find the value of (2x – 4)²

4 (x – 2)²

⇒ 4 (x² – 4x + 4)

⇒ 4 (–1 + 4),    from (3)

⇒ 12

∴ The correct answer is 12.

Shortcut TrickConcept used:

⇒ x4 + 1/x4 = p

⇒ x2 + 1/x2 = √{p + 2} 

Calculation:

According to the question:

⇒ x4 + x-4 = 194

⇒ x2 + 1/x2 = √{194 + 2}

⇒ x2 + 1/x2 = 14

Now, 

⇒ x + 1/x = √{14 + 2}

⇒ x + 1/x = √16 = 4

⇒ x² + 1 = 4x

⇒ x2 + 4x = - 1   ------(1)

So, (2x – 4)2 = (2)² (x - 2)²

⇒ 4 (x – 2)2

⇒ 4 (x2 – 4x + 4)

⇒ 4 (–1 + 4),    from (1)

⇒ 12

∴ The correct answer is 12.

Given:

C.I = Rs. 6,961.5; rate = 21%; time = 2 yrs

Formula used:

Simple interest = (P × R × T)/100

Compound interest = P [(1 + r/100)² – 1]

Calculation: 

⇒ 6,961.5 = P × [(1 + 21/100)² – 1]

⇒ 6,961.5 = P × [(121/100)² – 1]

⇒ 6,961.5 = P × (14641 – 10000)/10000

⇒ 6,961.5 = P × (4641/10000)

⇒ P = (6, 961.5 × 10000)/4641 = 15000

So, S.I = 15000 × 21 × 2/100 = 6300

⇒ S.I = Rs. 6300

∴ The correct answer is Rs. 6300.

 Shortcut TrickCalculation:

Effective rate of 2 yrs at 21% = 46.41%

So, P × 46.41 % = 6961.5

⇒ P = 6961.5/46.41 % = 15000

Now, S.I = (P × R × T)/100

⇒ S.I = (15000 × 21 × 2)/100 

⇒ S.I = 6300

∴ The correct answer is Rs. 6300.

Given:

cos = 4x and sin θ = 4x, x ≠ 0

Concept used:

sin2θ + cos2θ = 1

Calculation:

⇒ sin²θ + cos²θ = 1

⇒ (4/x)² + (4x)² = 1

⇒ 16 (1/x² + x²) = 1

⇒ (1/x² + x²) = 1/16

∴ The correct answer is 1/16.

Calculation:

C.P of article = marked price × 80% × 95%

So, C.P of article = 30000 × 4/5 × 19/20 = 22800

Additional expenditure = 1200 

So, total C.P of article = 22800 + 1200 = 24000

Given that S.P of article = 30000

So, gain = 30000 – 24000 = 6000

Gain% = (gain /C.P) × 100

Gain% = (6000/24000) × 100 = 25%

∴ The correct answer is 25%.

Given:

The average age of 15 person is 32 years.

Formula used: 

Average age = sum of ages of all persons/number of persons

Calculation:

Sum of ages of 15 persons = average age × 15

Sum of ages of 15 persons = 32 × 15 = 480

Let the ages of two persons are x and y

According to question,

Average age of 17 persons = 32 + 3 = 35

So, the sum of ages of 17 persons = 17 × 35 = 595

According to the question:

Sum of ages of 15 person + x + y = sum of ages of 17 persons 

⇒ 480 + x + y = 595

⇒ x + y = 595 – 480

⇒ x + y = 115      ----(1)

It is given that their age difference is 9 years 

⇒ x – y = 9      ----(2)

On subtracting (2) from (1) we get

⇒ y = 53

∴ The age of younger person = 53 years

Calculation:

For year 2014–2015, percentage increase of passed students as compared to previous year = (200 – 150)/150 × 100 = 33.33%

For year 2015–2016, percentage increase of passed students as compared to previous year = (300 – 200)/200 × 100 = 50%

For year 2016-2017 percentage increase of passed students as compared to previous year = (250-300)/300 × 100 = -16.66%

(Negative sign means there is decrease in percentage of passed students in 2016-2017 in comparison to 2015 -2016)

For year 2017–2018, percentage increase of passed students as compared to previous year = (300 – 250)/250 × 100 = 20%

∴ For the year 2017–2018, the percentage increase in a total number of passed students is the lowest in comparison to its previous academic year.

Given:

The sum of the salaries of A and B is Rs. 42,000.

Calculation:

A spends 75% of his salary, his saving 25% of his salary

B spends 90% of his salary, his saving 10% of his salary

According to condition,

Saving of A = saving of B

⇒ 25% A = 10% B

⇒ A : B = 2 : 5

Now salary of B = (5/7) × 42,000 = 5 × 6, 000 = 30,000

∴ The correct answer is Rs.30000.

Calculation:

The total number of students who passed in the five academic years = 150 + 200 + 300 + 250 + 300 = 1200

 Average number of passed students = total students/Number of years

Average number of passed students = 1200/5 = 240

∴ The correct answer is 240.

Calculation:

Total number of students = 150 + 100 + 200 + 100 + 300 + 50 + 250 + 100 + 300 + 100 = 1650

Total number of failed students = 100 + 100 + 50 + 100 + 100 = 450

Required percentage = 450/1650 × 100 = 27.27% ≈ 27%

∴ The correct answer is 27%.

Given:

A can complete a piece of work in 15 days.

B can complete a piece of work in 10 days.

Calculation:

Ratio of number of days taken by A and B to complete the work = 15 : 10 = 3 : 2

Ratio of efficiency of A and B = 2 : 3

Let their share is in the ratio of 2x and 3x

Now

⇒ 2x + 3x = 75000

⇒ 5x = 75000

⇒ x = 15000

Share of A = 2x = 15000 × 2 = Rs. 30000

∴ The correct answer is Rs. 30000.

Given:

cos x = $\frac{-\sqrt{3}}{2}$

Calculation:

cos x = $\frac{-\sqrt{3}}{2}$ then,

⇒ x = 7π/6 (210°)  [as π < x < 3π/2 ]

So, the value of 2 cot²x + 3 cosec²x

⇒ 2(√3)² + 3(-2²) = 18

∴ The correct answer is 18.

Calculation:

⇒ \(\frac{46-\frac{3}{4}of32-6}{11+\frac{3}{4}of\left( 34-6 \right)}\)

⇒ $\frac{46-3\times 8-6}{11+3\times 7}$

⇒ $\frac{46-24-6}{11+21}$

⇒ $\frac{46-30}{32}$

⇒ 16/32

Simplified value = 1/2

∴ The correct answer is 1/2.

Given:

The ratio between the speeds of two trains is 2 : 5

Calculation:

For first train, Speed = distance/time

t = 5 hr, distance = 250

⇒ s = 250/5 = 50 km/hr

⇒ The speeds of two trains = 2 : 5

∴ The difference between the speeds (in km/h) of both the trains= 50 × 3/2 = 75 km/hr

Given:

∠BAC = 52°

Calculation:

⇒ ∠BOC = 90° - ∠A/2

⇒ ∠BOC = 90° - (52°/2)

⇒ ∠BOC = 90° - 26°

⇒ ∠BOC = 64°

∴ The correct answer is  64°.

Alternate MethodGiven:

∠A  = 52°

Calculation:

∠A + ∠B + ∠C = 180°

52° + ∠B + ∠C = 180°

∠B + ∠C = 128°

Let ∠B = x° , ∠C  = y°

Now, 

AB is extended to D, 

∠ABD = 180°

∠ABD =  ∠ABC  +  ∠DBC = 180°

x + ∠DBC = 180° 

∠DBC = (180° - x)

Similarly, 

∠ECB = (180° - y)

Now,

As per the triangle Law,

$\frac{{\angle ECB}}{2} + \frac{{\angle DBC}}{2} + \angle O = {180^ \circ }$

$\frac{{{{180}^ \circ } - x}}{2} + \frac{{{{180}^ \circ } - y}}{2} + \angle O = {180^ \circ }$

${180^ \circ } - \frac{x}{2} - \frac{y}{2} + \angle O = {180^ \circ }$

$\angle O = \frac{{x + y}}{2} = \frac{{{{128}^ \circ }}}{2} = {64^ \circ }$

∴ The correct answer is  64°.

Calculation:

⇒ 72 = 9 × 8, where 9 and 8 are co–prime

⇒ 64x29y6 is should be divisible by 9 and 8

Divisibility rule of 8,

⇒ Last three digits 9y6 so minimum value of y = 3

Divisibility rule of 9,

⇒ 30 + x also divisible by 9 so x = 6

The value of (2x – 3y) = 12 – 9 = 3

∴ The correct answer is 3.

Calculation:

In year 2013–2014, difference of passed and failed students = 150 – 100 = 50

In year 2014–2015, difference of passed and failed students = 200 – 100 = 100

In year 2015– 2016, difference of passed and failed students = 300 – 50 = 250

In year 2016–2017, difference of passed and failed students = 250 – 100 = 150

In year 2017–2018, difference of passed and failed students = 300 – 100 = 200

∴ In the year 2013–2014 the difference between the number of students passed and failed students is the lowest

Given:

A earns = 640 per day

B earns = 360 per day

Calculation:

Since A earns Rs. 640 per day and B earns Rs. 360 per day

Required ratio = 360 : 640 = 9 : 16

∴ The correct answer is 9 : 16.
