SSC CHSL Previous Paper 24 (Held On: 16 Oct 2020 Shift 3) (Previous Year Paper)

The correct answer is 'will arrive on'. 

Key Points

• The given sentence is grammatically incorrect.
• Here, 'be' is used wrongly. We know that when the sentence is in the future continuous tense 'be + V₁ + ing' is used. But here 'be' is used without 'ing' form.
• The given sentence is in the 'Future Indefinite' tense. And using 'ing' with 'arrive' makes the sentence incorrect.
• This tense is used when the action is to take place in the future.
• The adverbs which indicate future indefinite actions are: soon, in a few moments, tomorrow, next year/month/week.
• And we know that the structure of future indefinite tense is: Subject + shall/will + V₁ + Object.
• Therefore, the correct answer is Option 3.
  

​

Correct Answer: The new product will arrive on supermarket shelves only next year.  

Additional Information

• The structure of the future progressive tense is as follows:
• The future progressive tense is used when the action is going on or continuing in the future.
• Subject + shall/will + be + v₁ + ing + object. 
• Example: They will be playing chess in the common room.
• The future progressive action can be written at 'the point of time'. 
• Example: It will probably be snowing when you reach Switzerland.

The correct answer is 'Utopia'. 

Key Points

• The most appropriate one-word for the given group of words is 'Utopia'.

• Let's look at the meaning and examples of the given options: 

• | Evangelist | a person who tries to persuade people to become Christians, often by travelling around and organizing religious meetings | The evangelist wanted to preach at the Charlotte Coliseum. | | --- | --- | --- | | Utopia | a perfect society in which people work well with each other and are happy | Try and imagine a perfect society, a utopia, in which the government really got everything right. | | Hypocrite | a situation in which someone pretends to believe something that they do not really believe or that is the opposite of what they do or say at another time | There's one rule for her and another rule for everyone else and it's sheer hypocrisy. | | Responsible | to have control and authority over something or someone and the duty of taking care of it, him, or her | Her department is responsible for overseeing the councils.
  |

• Therefore, by reading the above explanations we find that the correct answer is Option 2.

The correct answer is 'Rama told me that she needed my help for her new assignment.'

Key Points

• The given sentence is in Direct Speech. As per the given question, we have to change it into Indirect Speech.

• Comma and inverted commas will be removed.
• 'That' conjunction will be added.
• 'I' will be changed into 'she'. We know that the first person pronoun is changed according to the subject of the reporting verb.
• 'Need' will be changed into 'needed'.
• 'Your' will be changed into 'my'. We know that the second person pronoun is changed according to the object of the reporting verb.
• 'My' will be changed into 'her'.
• Therefore, the correct answer is Option 3. 
  

​

Correct Answer: Rama told me that she needed my help for her new assignment.

• Inverted Commas will be removed. And conjunction 'to/not to' will be used.
• Example: 
• He said, "Mohan, please bring me my towel." (Direct Speech)
• He requested Mohan to bring him his towel. (Indirect Speech)

The correct answer is 'A new serial about the life of Dr. Ambedkar is being watched by my mother.'

Key Points

• The given sentence is in Active Voice. As per the question, we have to change it into Passive Voice.
• The process of transformation is as follows: 
• The subject of the sentence is ''My mother''.
• The object of the sentence is ''a new serial''.
• We know that in Active to Passive transformation the subject will be put in the place of the object and the object will be put in the place of the subject.
• 'Is watching' will be changed into 'is being watched'. We know that 'V₁ + ing' is changed into 'Being + V₃'.
• Therefore, the correct answer is Option 1. 
  

​

Correct Answer: A new serial about the life of Dr. Ambedkar is being watched by my mother.  

Additional Information

• The transformation of imperative sentences:
• If someone gives a command, do request, express a desire or wish, in sentences then such sentences are called an imperative sentence.
• If the notion of a sentence is 'Command' then structure: 
• V1 + Object. (Active Voice)
• Let + subject + be + V3. (Passive Voice)
• Example: 
• Teach your students. (Active Voice)
• Let your students be taught. (Passive Voice)
• If the notion of a sentence is that of an 'Order', then structure: 
• V1 + Object. (Active Voice)

• Example: 
• Drive the car. (Active Voice)
• You are ordered to drive the car. (Passive Voice)

The correct answer is 'children'. 

Key Points

• The most appropriate word for the given fill in blank is 'children'.
• The author is talking about visiting an orphanage. We know that an orphanage is a place for children whose parents are dead or unable to care for them.
• An orphanage has many children.
• In the given fill in blank Option 1 cannot be the answer because it is singular. Here, a plural form should be used. We know that the plural form of 'child' is 'children'.
• Therefore, the correct answer is Option 1. 
  

​

Correct Answer: Recently, I visited an orphanage for differently-abled children in Delhi.

• We tend to mark Option 3 but it would be wrong because "Children's" means belonging or relating to children.
• It shows possession. But here, a plural form should be used. 
• Example: 'children's clothes' or 'children's literature'.
• Therefore, the correct answer is Option 1.

The correct answer is 'made'. 

Key Points

• The most appropriate word to fill in the blank is 'made'.
• The given sentence "The courteous staff______me feel at home and allowed..." is in the past tense.

• Hence, the correct answer is Option 1. 
  

​

Correct Answer: "The courteous staff made me feel at home and allowed..."

• We tend to go for Option 3 but it would be wrong because the given sentence is in the past tense.
• Therefore, the correct answer is Option 1.

The correct answer is 'freely'.

• Therefore, by reading the above explanations we find that the correct answer is Option 3. 
  

​

Correct Answer: "to interact freely with the children..."

The correct answer is 'for'. 

Key Points

• The most appropriate word for the given fill in the blank is 'for'.

• In the given question, the possessive adjective of 'they', that is, 'their' should be used.
• It indicates possession by people or things. More specifically, "their" is a possessive adjective.
• It replaces the noun in a sentence.
• Instead of saying, "That's the John family's new dog," we can say, "That's their new dog."
• While "his" and "her" demonstrate singular possession (possession by one person), "their" is reserved for two or more people or things.
• In the given sentence 'their' is used for all the children of the orphanage.
• Therefore, the correct answer is Option 1. 
  

​

Correct Answer: "The children were a cheerful lot, the smiles on their faces reflecting the joy within on receiving gifts."

The correct answer is 'ADBC'. 

Key Points

• The given sentence is an example of a Sentence Jumble.

• Part A will be the first sentence because it is talking about a past happening. It talks about Einstein's distaste for 'forced' learning.
• Part D will be the next sentence because it explains what he felt about formal education. It seems that Einstein was not happy with the way the education system works.
• Einstein was critical of the exam-based education system. Therefore, the next sentence will be Part B.

• Therefore, the correct answer is Option 2. 
  

​

Correct Answer: Einstein had a deep distaste for enforced learning and was known to skip many of his college lectures. He often felt that formal education interfered with his natural desire to learn and explore. Einstein was also severely critical of the exam-based education system. The great physicist Galileo too said, “You cannot teach anybody anything. You can only help them discover it within themselves.”

The correct answer is 'in a year 2020'. 

Key Points

• The given sentence is grammatically incorrect.
• The erroneous part 'in a year 2020' should 'in the year 2020'.

• ​Do use 'the' before:
• names of rivers, oceans, and seas: the Nile, the Pacific
• points on the globe: the Equator, the North Pole
• geographical areas: the Middle East, the West
• deserts, forests, gulfs, and peninsulas: the Sahara, the Persian Gulf, the Black Forest, the Iberian Peninsula

​

Correct Answer: We can see many changes in Government schools these days. 

Additional Information

• We use the quantifiers much, many, a lot of, lots of to talk about quantities, amounts, and degree. We can use them with a noun (as a determiner) or without a noun (as a pronoun).

• In informal styles, we prefer to use 'lots of or a lot of'.

• Example:

• I went shopping and spent much money.

• I went shopping and spent a lot of money.

Key Points

• The given sentence is grammatically incorrect.
• Here, the second form of verb should be used because the given sentence is in the past tense.
• Because the given sentence is talking about a past time when they visited forest.
• Therefore, 'sensed' should be used here. 
  

​

Correct Answer: After walking a few steps in the forest, our guide sensed some sort of movement in the foliage behind us.  

Additional Information

• The usage of before, after and until: 
• We use before and after to talk about the order of events in the past or future. With before and after, either the main clause or the subordinate clause can come first. 
• Example: 
• She will pick you up before she comes here. 
• Here, in this sentence 'She will pick you up' is the first event. And 'She comes here' is the second event.
• After she comes here, she will pick you up. 
• Here, in this sentence 'After she comes here' is the first event. And 'she will pick you up' is the second sentence.
• 'Until' as a time conjunction means up to a time in the past or future. In the case of 'until', the main clause usually comes first.
• Example: I’m going to wait until the January sales start to buy a new jacket.

The logic is:

9 : 72 → 9 × (9 – 1) = 72

Similarly,

5 : ? → 5 × (5 – 1) = 20

Hence, ‘20’ is the correct answer.

Faces opposite to each other is shown below:

So, the face opposite to the face having number '1' is ‘6’.

Hence, ‘6’ is the correct answer.

The logic is:

1^st Number × 3^rd Number = 2^nd Number

1. 600 → 6 × 0 = 0

2. 441 → 4 × 1 = 4

3) 324 → 3 × 4 = 12 ≠ 2

4. 393 → 3 × 3 = 9

Hence, ‘324’ is the odd one out.

Confusion Points

• All numbers are divisible by 3, so divisibility rule does not follow.
• 441 and 324 both are perfect square of 21 and 18, so logic of a perfect square does not follow.

The logic is:

Coach : Player → A coach is a person who guides and coaches players.

Similarly,

Teacher : Student → A teacher is a person who teaches and guides a student.

Hence, ‘Teacher : Student’ is the correct answer.

The logic is:

'Tree' is related to 'Mango' → Mangoes are a fruit of Mango tree.

Similarly,

'Vine' is related to '______' → Grapes are fruit of a vine plant.

Hence, ‘Grape’ is the correct answer.

The logic is:

(2, 6, 42) → 2 × (2 + 1) = 6; 6 × (6 + 1) = 42

Similarly,

2. (1, 2, 6) → 1 × (1 + 1) = 2; 2 × (2 + 1) = 6

Other option do not follow the similar pattern:

1. (4, 12, 86) → 4 × (4 + 1) = 20 ≠ 12; 12 × (12 + 1) = 156 ≠ 86

2. (9, 13, 43) → 9 × (9 + 1) = 90 ≠ 13; 13 × (13 + 1) = 182 ≠ 43

3. (4, 8, 39) → 4 × (4 + 1) = 20 ≠ 8; 8 × (8 + 1) = 56 ≠ 39

Hence, ‘(1, 2, 6)’ is the correct answer.

The pattern followed here is:

First, the given word need to be arranged in alphabetical order (A - Z),

BLISS will be BILSS, then

Similarly,

STOP will be OPST, then

Hence, "TTRR" is the coded form.

Let the Aman has ‘x’ number of notes of each one, five, ten and twenty rupee bank notes.

According to question:

x + 5x + 10x + 20x = 1080

⇒ 36x = 1080

⇒ x = 1080 ÷ 36

⇒ x = 30

So, total bank notes that Aman has = 4 × 30

= 120

Hence, ‘120’ is the correct answer.

Using options:

aabccdee / aabccdee / aabcbcee / aacdcdee

Not following any pattern

aabccdee / aabccdee / aabcabce / acdecdee

Not following any pattern

aabccdee / aabccdee / aabccdee / aabccdee

Following pattern

abbcceae / aacdcdee / aabcbcae / acdecdee

Not following any pattern

Hence, ‘aacdebceacdeabc’ is the correct answer.

1. 28 and 2

Given expression: 6 + 28 ÷ 4 – 2 × 17 = 12

After replacing the numbers, we get:

L.H.S = 6 + 2 ÷ 4 – 28 × 17

= 6 + 0.5 – 476

= 482 – 0.5

= 481.5 ≠ R.H.S

2. 17 and 6

Given expression: 6 + 28 ÷ 4 – 2 × 17 = 12

After replacing the numbers, we get:

L.H.S = 17 + 28 ÷ 4 – 2 × 6

= 17 + 7 – 12

= 24 – 12

= 12 = R.H.S

3. 17 and 4

Given expression: 6 + 28 ÷ 4 – 2 × 17 = 12

After replacing the numbers, we get:

L.H.S = 6 + 28 ÷ 17 – 2 × 4

= 6 + 1.64 – 8

= 7.64 – 8

= - 0.36 ≠ R.H.S

4. 6 and 4

Given expression: 6 + 28 ÷ 4 – 2 × 17 = 12

After replacing the numbers, we get:

L.H.S = 4 + 28 ÷ 6 – 2 × 17

= 4 + 4.66 – 34

= 8.66 – 34

= - 25.34 ≠ R.H.S

Hence, ‘17 and 6’ is the correct answer.

According to the English Alphabet series and its positional value:

The pattern followed here is:

S + K+ I + L + L - 6

In the given figure,

AB = 20 cm

CA = (1/2) × AB

⇒ (1/2) × 20

⇒ 10 cm

OA = radius = 15 cm

(OC)² = (OA)² – (CA)²

⇒ (OC)² = 15² – 10²

⇒ (OC)² = 225 – 100

⇒ OC = √125

⇒ OC = 5√5 cm

∴ The distance of the chord from the centre of the circle is 5√5 cm.

Calculation:

Let the numerator of the fraction be N, and the denominator of the fraction be D.

New numerator = N + (15/100) × N

⇒ (100N + 15N)/100

⇒ 115N/100

New denominator = D – (20/100) × D

⇒ (100D – 20D)/100

⇒ 80D/100

New fraction = 115N/80D

⇒ (17/65) = (23N/16D)

⇒ 17 × 16D = 23N × 65

⇒ 272D = 1495N

⇒ N/D = 272/1495

∴ The original fraction is 272/1495.

Shortcut TrickCalculation:

Let the fraction = P/Q

According to the question:

⇒ \(P~ ×~ 115 %\over Q × 80%\) = $17\over65$

Formula Used:

x² + y² = (x + y)² – 2xy

x³ + y³ = (x + y) (x² – xy + y²)

x⁴ + x⁴ = (x² + y²)² – 2x²y²

Calculation:

x³ + y³ = (x + y) (x² – xy + y²)

⇒ 12 = 4 × (x² – xy + y²)

⇒ x² + y² = 3 + xy

⇒ (x + y)² – 2xy = 3 + xy

⇒ 4² – 3 = 3xy

⇒ xy = (16 – 3)/3

⇒ xy = 13/3

x⁴ + y⁴ = (x² + y²)² – 2x²y²

⇒ (3 + xy)² – 2 × (13/3)²

⇒ [3 + (13/3)]² – 2 × (169/9)

⇒ [(9 + 13)/9]² – 338/9

⇒ (484/9) – 338/9

⇒ (484 – 338)/9

⇒ 146/9

∴ The value of x⁴ + y⁴ is 146/9.

⇒ 100 = (100 × r × 12)/100

⇒ r = 100/12

⇒ r = 25/3

$\Rightarrow {\rm{r}} = 8\frac{1}{3};\%$

∴ The rate of interest is $8\frac{1}{3};\% .$

Given:

x – y = 13

xy = 25

Formula Used:

(x – y)² = x² + y² – 2xy

(x + y)² = x² + y² + 2xy

x² – y² = (x – y) × (x + y)

Calculation:

x – y = 13

Squaring both the sides

⇒ (x – y)² = 13²

⇒ x² + y² – 2xy = 169

⇒ x² + y² = 169 + 2 × 25

⇒ x² + y² = 219

(x + y)² = x² + y² + 2xy

⇒ (x + y)² = 219 + 2 × 25

⇒ (x + y) = √(269)

x² – y² = (x – y) (x + y)

⇒ x² – y² = 13√269

∴ The value of x² – y² is 13√269.

Calculation:

33 × C.P = x × S.P

∴ The correct answer is 1.

Given:

2sin2 x = 2 - 3sin x

Concept used:

π = 180^° 

sin 30^° = 1/2

Calculation:

2sin² x + 3sin x - 2 = 0

⇒ 2sin² x + 4sin x - sin x - 2 = 0

⇒ 2sin x(sinx + 2) - 1(sinx + 2) = 0

⇒ (2sin x - 1)(sinx + 2) = 0

⇒ 2sin x - 1 = 0 or sin x + 2 = 0

⇒ sin x = 1/2 or - 2

(∵ sin θ ≠ negative)

So, sin x = 1/2 

⇒ sin 30^° = 1/2

⇒ x = 30^° = π/6

∴ The value of x is π/6.

Given:

PQ = 13 cm and PR = 12 cm

Concept used:

Calculation: 

Let the set of three number is respectively a, b, and c.

According to the question

The sum of first number is 

⇒ a + b = 2 × 7

⇒ a + b = 14      ----(1)

The sum of the last two number is 

⇒ b + c = 2 × 10     

⇒ b + c = 20      ----(2)

The sum of the first and last number is 

⇒ c + a = 2 × 14

⇒ c + a = 28      ----(3)

Add eq. (1), (2) and (3) 

⇒ 2(a + b + c) = 14 + 20 + 28

⇒ (14 + 20 + 28)/2

⇒ 62/2

⇒ 31

So,

The average of the three number is 

⇒ 31/3

∴ The required average is 31/3. 

Short approach:

The average of the three numbers is 

⇒ (7 + 10 + 14)/3

⇒ 31/3

∴ The required average is 31/3.

• In other words, the production possibility curve can be defined as a graph that represents different combinations of quantities of two goods that can be produced by an economy under the condition of limited available resources. It is also known as the production possibility frontier(PPFs) or transformation curve.
