SSC CHSL Previous Paper 16 (Held On: 8 Jul 2019 Shift 3) (Previous Year Paper)

The correct answer is option 4) i.e. are a greatest

• The subject in the given sentence is 'climate change' which is a singular subject, hence, the auxiliary verb 'is' will be used in place of 'are'.
• And article 'the' is used before the superlative degree, hence, 'the greatest' will be used in the given sentence.
• So, the correct sentence will be: Climate change is the greatest threat facing our planet which needs our immediate attention.

The correct answer is option 4) i.e. reconciliation.

• Retaliation: the action of returning a military attack; counter-attack.
• Reconciliation: the restoration of friendly relations. This is the most appropriate antonym of the given word.
• Retrospection: the action of looking back on or reviewing past events or situations, especially those in one's own life.
• Retribution: punishment inflicted on someone as vengeance for a wrong or criminal act.
• Regression: a return to a former or less developed state.

The correct answer is option 3) i.e. She told you that she had a thousand rupees in her purse then.

Key Points

• 'Said to' will be changed into 'told' while making the indirect speech of the given sentence.
• 'I' will be changed according to 'subject' in the reported speech i.e. 'she'.
• the entire sentence will be in the past tense, hence, 'have' will be changed into 'had'.
• 'my' will be changed according to 'she' and 'her' will be used.
• 'now' is changed into 'then' while converting direct speech into indirect speech.

The correct answer is option 3) i.e. the better singer.

• In the given sentence a comparison is being made between two persons, hence, 'better' will be used here.
• When we have to choose one out of two persons we used the article 'the' with the comparative degree, hence, 'the better' will be used.

The correct answer is option 1) i.e. Great many students.

• The phrase 'great many' used in the given sentence is wrong.
• The correct phrase is 'a great many' which is used to refer to a large number of things or persons.
• So, the correct sentence will be: A great many students who are good at other subjects perform poorly in English.

• The correct answer is Option 4.
• The meaning of the given words:
• Discover: To find or learn something for the first time.
• Neglect: To fail to care.

• Hide: To put out of sight.
• Find: To encounter or discover something
• Therefore, out of given alternatives, the word 'find' gives the similar meaning as the given word.

• The correct answer is Option 4.
• In the given sentence it is talking about a specific mistake, therefore, we have to use the definite article 'the'.
• The correct sentence is 'This was the only mistake he made.'

​Through thick and thin: Despite difficult or troubling circumstances or setbacks; through good and bad times.

• E.g: Our company has survived through thick and thin, and we'll be able to get through this challenge as well.
• She's always been there for me through thick and thin, so I can't turn my back on her now.

Thus, option 4 is the correct answer.

The mirror image of the question figure is as follows:

Hence, the correct answer is option 3.

Let's check each option:

1. 49 → 4 + 9 = 13 → (odd)

2. 16 → 1 + 6 = 7 (odd)

3. 25 → 2 + 5 = 7 (odd)

4. 64 → 6 + 4 = 10 → even

Hence, 64 is the odd one among the given alternatives.

1 and 3 are adjacent to 5 in the first position of the dice.

4 and 6 are adjacent to 5 in the second position of the dice.

The only number left is 2.

Hence, 2 must be on the face opposite to the one having 5.

The steps in the process of a student's transit from class 12 to college are as follows:

5. Annual Examination – Class 12
6. Result declaration – Class 12
7. Applying for admission to college
8. Admission merit list declaration
9. Getting admission in the college
10. Attending classes in college

Hence, the correct sequence is 5, 6, 4, 2, 3, 1.

Let's check each option:

1. x y y y q s q t -  x z z y q s q t -  x z y y q s q t → doesn't follow a pattern

2. x z y y q s q t -  x z y y q s q t  - x y z y q s t t → doesn't follow a pattern

3. x z y y q s q t  -  x z y y q s q t  -  x z y y q s q t → Follows a pattern i.e. xzyyqsqt

4. x z y y q q s t  - x z y z q s q t  - x z y y q s q t → doesn't follow a pattern

Hence, the correct answer is 'z y s q y y z y q'.

The pattern followed here is:

4³ = 64 and 7² = 49

Add both to get the middle number: 64 + 49 = 113

Similarly, for the set (5,141,4):

5³ = 125 and 4² = 16

Add both to get the middle number = 125 + 16 = 141

Hence, the correct answer is (5, 141, 4).

Lentils are a type of pulses and pulses are a type of food.

Hence, the correct answer is option 2.

A ‘tadpole’ grows into a frog. Similarly, a caterpillar grows into a butterfly.

Hence, 'butterfly' is the correct answer.

Given that  A + B + C = 153 ….(i)

C = 5A ….(ii)

B = 3A ….(iii)

Now, from (i), (ii), and (iii),

A + 3A + 5A = 153

9A = 153

A = 153 ÷ 9

A = 17

B = 3A

B = 3 × 17 = 51

Hence, B gets 51 rupees.

The pattern followed here is:

Similarly,

Hence, the correct answer is 69955437.

In the given series, the circle and the square simultaneously rotate at an angle of 45° in the clockwise direction. 

The circle is shaded at alternate steps starting from the first step.

The square is shaded at alternate steps starting from the second step.

Thus, in the answer figure, only the circle must be shaded and the two shapes must be diagonally opposite to each other.

Only option 4 satisfies this condition.

2) 

3) 

4) 

Hence, JNRW is the odd one among the given alternatives.

Meticulous is a synonym for detailed.

Similarly, obese is a synonym for fat.

Hence, the correct answer is Fat : Obese.

The pattern followed here is:

2³ = 8 +1 = 9

Similarly,

4³ = 64 +1 = 65

Hence, the correct answer is 4 : 65.

Using the symbols in the below table, we can draw the family tree.

D + P ÷ I × K ÷ T – R

After decoding:

D + P means D is sister of P.

P ÷ I means P is the mother of I.

I × K means I is brother of K.

K ÷ T means K is mother of T.

T – R means T is daughter of R.

Hence, R is P’ daughter’s husband.

The question figure is embedded in the below figure:

Hence, the correct answer is the figure in option 2.

The pattern followed here is:

Hence, 352 will be the next number in the series.

The triangles are as follows:

Hence, there are 30 triangles in the given figure.

The pattern followed here is:

Similarly,

Hence, KFPHFLOD is the correct answer.

731 ÷ 13 + 450 – 25 × 43 = 142

After interchanging 13 and 43 and using BODMAS rule we get the following:

731 ÷ 43 + 450 – 25 × 13

= 17 + 450 – 25 × 13

= 17 + 450 – 325

= 467 – 325

= 142

Hence, the correct answer is '13 and 43'.

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

Hence, the correct answer is option 1.

The pattern followed here is:

Similarly,

Hence, the correct answer is GRRC.

The pattern followed here is:

(8, 112, 28) → 112 ÷ 28 × 2 = 8

Similarly,

(14, 364, 52) → 364 ÷ 52 × 2 = 14

Hence, (14, 364, 52) is the correct answer.

Here, nervous, anxious and apprehensive are synonyms of worried whereas serene means calm and peaceful.

Hence, serene is the odd word among the given alternatives.

The least possible Venn diagram is as follows:

Conclusions:

I - Some onions are chilies → False (it is possible but not definite)

II - Some onions are potatoes → True (some potatoes are onions)

III - No onion is chilly → False (it is possible but not definite)

Here, conclusions I and III form a complementary pair.

Hence, conclusion II and either conclusion I or III follow.

Given:

The sum of the salaries of A and B together is 45000

Savings of A and B are the same

Calculation:

According to the question:

⇒ A × 15% = B × 30%

⇒ A = 2 B

⇒ A/B = 2/1

Let the salaries of A and B be 2x and x, respectively.

Salaries of A and B = 45000

⇒ 2x + x = 45000

⇒ 3x = 45000

⇒ x = 15000

∴ Salary of B = Rs. 15000

Calculation:

Let the radius of both circles be R and r and the distance between their center is d

Now,

R = 3 cm, r = 2 cm and d = 13 cm

Transverse common tangent (PQ)=  √{d² - (R + r)²}

⇒ √{(13)² - (3 + 2)²} = 12 cm

∴ The correct answer is 12 cm.

Given:

A earns per day = Rs. 640

B earns per day = Rs. 360

Calculation:

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

∴ Required ratio = 640 : 360 = 16 : 9

∴ The correct answer is 16 : 9.

Calculation:

Total age of 15 persons = 15 × 32 = 480

After adding 2 more persons the new average will be = 32 + 3 = 35

Now the total age of 17 persons = 17 × 35 = 595

Age of two new persons = 595 – 480 = 115

The two new people have an age difference of 9 years

Let the age of younger is x year and age of older is x + 9 years

∴ x + x + 9 = 115

⇒ 2x = 115 – 9 = 106

⇒ x = 53

∴ The age of elder person = 53 + 9 = 62 years.

Alternate MethodDeflection in the average = 3 years

The total age of 2 new persons = 2 × 32 + 3 × 17 (3 is the increment and 32 is the original average)

The total age of 2 new persons = 115

∴ x + x + 9 = 115

⇒ 2x = 115 – 9 = 106

⇒ x = 53

∴ The age of elder person = 53 + 9 = 62 years

Given:

x⁴ + x^-4 = 47

x⁴ + 1/x⁴ = 47

Calculation:

x4 + 1/x4 = 47

Adding 2 to both sides,

(x⁴ + 1/x⁴) + 2 = 47 + 2

⇒ (x² + 1/x²)² = 7²

⇒ x² + 1/x² = 7

Adding 2 both sides

⇒ (x² + 1/x²) + 2 = 7 + 2

⇒ (x + 1/x)² = 9

⇒ x + 1/x = 3

⇒ x² + 1 = 3x

⇒ x² – 3x = -1      ---- (1)

We have to find

⇒ (2x - 3)² = 4x² + 9 – 12x

⇒ 4 (x² – 3x) + 9

⇒ 4 × -1 + 9

⇒ (2x - 3)² = 5

∴ The correct answer is 5.

Alternate Method⇒ x4 + 1/x4 = 47

⇒ x2 + 1x2 = √47 + 2

⇒  x2 + 1x2 = 7

Similarly

x + 1/x = √7 + 2

⇒ x + 1/x = 3     ....(1)

And,

x - 1/x = √7 - 2

⇒ x - 1/x = √5     ....(2)

Add equation (1) and equation (2),

⇒ 2x = 3 + √5

⇒ (2x - 3) = √5

⇒ (2x - 3)² = 5

∴ The correct answer is 5.

Calculation:

4 (cosec²65° - tan²25°) – sin 90°- tan²63° y tan²27° = y/2

⇒ 4 (cosec²65° − tan²(90° − 65°) – 1 – tan²(90° − 27°) tan²27° y = y/2

⇒ 4 (cosec²65° − cot²65°) – 1 – cot²27° tan²27°y = y/2

⇒ 4 – 1 – y = y/2

⇒ 3y/2 = 3

⇒ y = 2

∴ The correct answer is 2.

Given:

r = 21%

Calculation:

Compound interest rate for 2 years = (21 + 21 + 21 × 21/100) = 46.41 %

Let certain sum be P

∴ P × 46.41% = 9282

⇒ P × (4641/100 × 100) = 9282

⇒ P = Rs. 20000

Again for SI

P = 20000, r = 21%, t = 2 years

SI = P × r × t /100 = 20000 × 21 × 2/100 = Rs. 8400

∴ The correct answer is Rs. 8400.

Given:

cos x = -√3/2, π < x < 3π/2

Concept Used:

sin² x + cos² x = 1

cot x = cos x / sin x

sec x = 1/ cos x

Calculation:

According to the question:

⇒ cos x = -√3/2

⇒ sin x = √1 - (-√3/2)²

⇒ sin x = √(1 - 3/4)

⇒ sin x = -1/2     [∵ π < x < 3π/2 and sinx is negative in 3rd quadrant]

cot x = cos x/sin x

⇒ cot x = √3

sec x = 1/cos x = -2/√3

2cot2 x – 3sec2 x

⇒ 2(√3)² - 3 × (-2/√3)²

⇒ 6 - 4

⇒ 2

∴ The correct answer is 2.

Calculation:

Let the C.P of article = Rs.100 each

Now

Total CP of three articles = 300

SP of first articles = 100 × 110/100 = 110

SP of second articles = 100 × 105/100 = 105

SP of third articles = 100 × 85/100 = 85

Total SP of three articles = 110 + 105 + 85 = 300

Now CP = SP

∴ No profit, no loss

Alternate MethodTotal profit/loss percentage = 10 + 5 -15 = 0

It means there is no profit or loss.

Calculation:

CP for dealer = 20000 × 80/100 × 95/100 = 15200

He spends Rs. 1800 on repairs

Total CP for dealer = 15200 + 1800 = 17000

SP for dealer = 20000

Profit = 20000 – 17000 = 3000

Profit percentage = (3000/17000) × 100 = 17.65%

∴ The correct answer is 17.65%.

Calculation:

Let the speeds of the both trains be 2x and 5x

Speed of first train = 350/5 = 70 km/h

∴ 2x = 70

⇒ x = 35

Difference between the speeds between them = 5x – 2x = 3x

Difference between the speeds between them = 3 × 35 = 105 km/h

∴ The correct answer is 105 km/h.

Given

a + b = 28

Calculation:

⇒ a + b = 28

Cubing both sides

⇒ (a + b)³ = (28)³

⇒ a³ + b³ + 3ab (a + b) = 21952

⇒ 1344 + 3ab × 28 = 21952

⇒ 3ab × 28 = 21952 – 1344 = 20608

⇒ 3ab = 736

∴ (a + b)² - 3ab = (28)² – 736 = 784 – 736 = 48

∴ The correct answer is 48.

Calculation:

⇒ $\frac{{46; - ;\frac{3}{4};of;32 - 6}}{{37 - ;\frac{3}{4};of;\left( {34; - ;6} \right)}}$

⇒ $\frac{{46; - ;24; - ;6;}}{{37 - ;\frac{3}{4};of;28}}$

⇒ $\frac{{46; - ;30}}{{37; - ;21}}$

⇒ 16/16 = 1

∴ The correct answer is 1.

Concept Used:

When a number is divisible by 72, it must be also divisible by 8 × 9

When a number is divisible by 8, then its last three digits will be also divisible by 8

Calculation:

According to the question,

⇒ 9y6 is divisible by 8 when y = 3

Again, when a number is divisible by 9 then its sum of digit must be divisible by 9

⇒ 5 + 4 + x + 2 + 9 + 3 + 6 = 29 + x

Possible value of x = 7

Because 29 + 7 = 36 is divisible by 9

∴ 2x + 3y = 2 × 7 + 3 × 3 = 14 + 9 = 23

∴ The correct answer is 23.

Concept used:

For successive, increase or decrease = x + y + xy/100

Calculation:

⇒ −13 – 13 + (-13) (-13)/100

⇒ -26 + 1.69 = - 24.31 %

∴ The area is decreased by 24.31%.

Given:

∠BOC = 106° 

Calculation:

We know that, ∠BOC = 90 + ∠A/2

⇒ 106° = 90° + ∠A/2

⇒ ∠A/2 = 16°

⇒ ∠A = 32°

∴ The correct answer is 32°.

Given

cosec θ = 5/x

cot θ = 5x

Calculation:

Now

⇒ cosec²θ – cot²θ = (25/x²) – (25x²)

⇒ 1 = 25 × {(1/x²) - x²}

⇒ -1 = 25 × {x2 - (1/x2)}

Dividing both sides by 5

⇒ 5 (x² – 1/x²) = -1 /5

∴ The correct answer is (- 1/5).

Calculation:

OP divide ∠APB equally

∴ ∠APO = ∠BPO = 36°

In ∆APB

∠OAP = 90°

⇒ ∠AOP = 180° − (36° + 90°) = 180° − 126° = 54°

Again In ∆ADO

∠AOD = ∠AOP = 54°

∠ADO = 90°

⇒ ∠OAB = 180° − (90° + 54°) = 180° − 144° = 36°

∴ The correct answer is 36°.

ΔABC ∼ ΔPQR

∴ (BC/QR)² = ar(∆ABC)/ar(∆PQR)

⇒ (8/QR)² = 4/25

⇒ 8/QR = 2/5

∴ QR = 20 cm

Note∶ The question was incorrect in the official paper. It has been corrected and updated it accordingly.

Given

⇒ x = √5 + 2

Concept used:

1/x = 1/(√5 + 2) × (√5 - 2)/(√5 - 2)

⇒ (√5 - 2)/(5 - 4) = √5 - 2

⇒ x – 1/x = p then,

⇒ x3 – 1/x3 = p³ + 3p

Calculation:

⇒ x – 1/x = √5 + 2 – (√5 – 2) = √5 + 2 − √5 + 2 = 4

⇒ x – 1/x = 4

Now, 

⇒ x3 – 1/x3 = (4)³ + 3 × 4

⇒ x3 – 1/x3 = 64 + 12 = 76

∴ The correct answer is x³ - x^-3 = 76.

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 B = 3x = 15000 × 3 = Rs. 45000

Calculation:

Total students in schools A and B for 6 years = 640 + 550 + 800 + 820 + 500 + 600 + 700 + 750 + 900 + 500 + 750 + 480 = 7990

∴ Required average = 7990/6 = 1331.67

Calculation:

The number of students taken together from the years 2008, 2012 and 2013 in school A

640 + 900 + 750 = 2290

The number of students taken together from the years 2008, 2012 and 2013 in school B

550 + 500 + 480 = 1530

∴ Required ratio = 2290 : 1530 = 229 : 153

Calculation:

In 2011 total number of students in school A and B = 700 + 750 = 1450

In 2012 total number of students in school A and B = 900 + 500 = 1400

In 2009 total number of students in school A and B = 800 + 820 = 1620

In 2008 total number of students in school A and B = 640 + 550 = 1190

∴ The sum of the students in two school, is the highest in year = 2009

Calculation:

Total students in school A and B in year 2010 = 500 + 600 = 1100

Total students in school A and B in year 2011 = 700 + 750 = 1450

Increase in number from 2010 to 2011 = 1450 - 1100 = 350

Percentage increase from 2010 to 2011 = (350/1100) × 100 = 31.81 %

Total students in school A and B in year 2008 = 640 + 550 = 1190

Total students in school A and B in year 2009 = 800 + 820 = 1620

Increase in number from 2008 to 2009 = 1620 - 1190 = 430

Percentage increase from 2008 to 2009 = (430/1190) × 100 = 36.13 %

Total students in school A and B in year 2011 = 700 + 750 = 1450

Total students in school A and B in year 2012 = 900 + 500 = 1400

It is cleared that Number of students decreased from 2011 to 2012

Total students in school A and B in year 2009 = 800 + 820 = 1620

Total students in school A and B in year 2010 = 500 + 600 = 1100

It is cleared that Number of students decreased from 2009 to 2010

∴ The percentage increase in the number of total students in schools A and B taken together is the highest in comparison to its previous year = 2009
