SSC Steno 2017 Official Paper (Held on: 11 Sep 2017 Shift 1) (Previous Year Paper)

The relation between the numbers is as follows,

33 + 10 = 43

10 + 43 = 53

43 + 53 = 96

Hence, the next number is 53 + 96 = 149

The relation between the numbers is as follows,

13 + 24 = 37

24 + 37 = 61

37 + 61 = 98

Hence, the next number is 61 + 98 = 159

The relation between the numbers is as follows,

9 × 2 + 1 = 19

19 × 2 - 1 = 37

37 × 2 + 1 = 75

75 × 2 - 1 = 149

Hence, the next number is 149 × 2 + 1 = 299

The relation between the numbers is as follows,

23 + 11 = 34

11 + 34 = 45

34 + 45 = 79

Hence, the next number is 45 + 79 = 124

The pattern is as follows,

Hence the next term is IJ.

The pattern is as follows,

Hence the next term is LMQ.

The pattern is as follows,

Thus the next term is MRS.

The arrangement is as follows:

Anger → Ankle → Antique → Aster

Thus, “Anger” will appear first when arranged in order of dictionary.

The arrangement is as follows:

Lamp → Lasted → Lively → Longer → Lost

Thus, 43125 is the answer.

The arrangement is as follows:

Omnious → Onion → Ostrich → Owl → Oxford

Thus, “Oxford” will appear last when arranged in order of dictionary.

The arrangement is as follows:

Kaizen → Kangaroo → Karma → Kite → Krypton

Thus, 42513 is the answer.

Out of the given options, 4 - 36 is odd one because in all other options 2^nd term is the multiple of 1^st term and one exceeding the 1^st term i.e.

9 - 90 → 9 × (9 + 1) = 9 × 10 = 90

6 - 42 → 6 × (6 + 1) = 6 × 7 = 42

5 - 30 → 5 × (5 + 1) = 5 × 6 = 30

But in 4 - 36, 4 × (4 + 1) = 4 × 5 = 20 which is not equal to 36.

Thus, 4 - 36 is odd one.

The pattern followed here is that the 2^nd number is one more than the cube of first number in each pair except in 5 - 124 i.e.

3 - 28 → 3³ + 1 =27 + 1 = 28

2 - 9 → 2³ + 1 = 8 + 1 = 9

4 - 65 → 4³ + 1 = 64 + 1 =65

But in 5 - 124 → 5³ + 1 = 125 + 1 = 126 ≠ 124

Thus, 5 - 124 is odd one.

Here, it follows a pattern of + 2 between two consecutive characters as shown below :

Hence, TVY is the odd one.

Here, it follows the pattern given below:

Hence, UVXW is the odd one.

In all of the above pair except Scooter: Garage the 1^st one is used to keep or shelter the 2^nd one i.e.

Hangar: Aeroplane → A Hangar is a large building with an extensive floor area, typically for housing and maintaining aircraft or aeroplane.

Yard: Train → A Yard or Train Yard is a place where Trains are sheltered, loaded, unloaded and maintained.

Depot: Bus → A Depot is a place where buses are sheltered and maintained.

Scooter: Garage → A Garage is a space where motor vehicle or vehicles are kept.

Hence, Scooter: Garage is the odd one.

In all of the above pair except Food: Hunger the 1^st one is an integral part of the 2^nd one i.e.

Room: House → Room is a part of a House.

Page: Book → Page is a part of Book.

Engine: Car → Engine is a part of Car.

Food: Hunger → Food is not a part of Hunger.

Hence, Food: Hunger is odd one.

Petrol, Coal and Natural Gas are used as fuel but Air is not a fuel

Hence, Air is off one here.

Pattern here is, second number is the square of the first number i.e.

110 : 12100 → 110² = 12100.

Similarly,

170² = 28900

Therefore 28900 is the correct answer.

Pattern here is, second number is one less than the square of first number i.e.

8 : 63 → 8² - 1 = 64 - 1 = 63

Similarly,

9² - 1 = 81 - 1 = 80

Therefore 80 is the correct answer.

Pattern here is, each digit of first number is squared and written starting from the left i.e. from first digit.

236 : 4936 → 2² 3² 6² → 4 9 36 = 4936

Similarly,

724 → 7² 2² 4² → 49 4 16 = 49416

Therefore, 49416 is the correct answer.

The pattern here is as follows,

Therefore, BWLG is the correct answer.

The pattern here is as follows,

Therefore, GKOPJJ is the correct answer.

The pattern here is as follows is replacing the letter by its opposite or reverse letter in alphabetical order i.e. A is replaced by Z, B by Y, C by X D by W and so on as shown in the figure below:

Hence the required conversion is,

Therefore, NZTPW is the correct answer

The pattern here is, second object is kept inside the first object i.e.

Wallet : Money → Money is kept inside the Wallet.

Similarly from the above options,

Clothes are kept inside the Almira.

Therefore, Clothes is the correct option.

The pattern here is, second direction is opposite of the first direction i.e.

Therefore, South - West is the correct answer.

The pattern here is, the second object (Shuttle) is used to play Badminton.

Similarly from the given options,

Ball is used to play Cricket.

Therefore, Ball is the correct answer.

Here, L means + and A means × i.e.

13 L 4 A 7 = 13 + 4 × 7 = 13 + 28 = 41

14 A 3 L 12 = 14 × 3 + 12 = 42 + 12 = 54

Similarly,

12 L 3 A 9 = 12 + 3 × 9 = 12 + 27 = 39

Hence, 39 is the correct answer.

The given equation is, 16 + 31 - 3 × 93 ÷ 11 = 966

Let’s check each option,

1. • and - 

16 - 31 + 3 × 93 ÷ 11 = 966

= 16 - 31 + 3 × 8.45 = 966

= 16 - 31 + 25.35 = 966

= 41.35 - 31 = 966 

= 10.35 = 966 (not equal)

2) - and ÷

= 16 + 31 ÷ 3 × 93 - 11 = 966

=  16 + 31 / 3 × 93 - 11 = 966

= 16 + 31 × 31 - 11 = 966

= 16 + 961 - 11 = 966 

= 977 - 11 = 966

= 966 = 966 (Equal)

3. ÷ and ×

= 16 + 31 - 3 ÷ 93 × 11 = 966

= 16 + 31 - 1/31 × 11 = 966

= 16 + 31 - 11/31 = 966 

= 16 + 31 - 0.35 = 966

= 47 - 0.35 = 966

= 46.65 = 966 (not equal)

4. × and +

= 16 × 31 - 3 + 93 ÷ 11 = 966

= 16 × 31 - 3 + 8.45 = 966

= 496 - 3 + 8.45 = 966

= 504.45 - 3 = 966

= 501.45 = 966 (not equal)

Hence, by interchanging - and ÷ the equation will be correct.

Let’s check each option,

1. LAID → can be formed as TRADITIONAL.

2. TRADE → cannot be formed as there is no ‘E’ in TRADITIONAL.

3. RADIATION → can be formed as TRADITIONAL.

4. RATIONAL → can be formed as TRADITIONAL.

Hence, TRADE can’t be formed from word TRADITIONAL.

Let’s check each option,

1. RANGE → can be formed as HANGOVER.

2. RAGE → can be formed as HANGOVER.

3. HOVER → can be formed as HANGOVER.

4. HANGS → cannot be formed as there is no ‘S’ in HANGOVER.

Hence, HANGS can’t be formed from word HANGOVER.

Consider the following least possible Venn diagram,

Conclusions:

I. Some blue are white → True.

II. Some yellow are white → True.

Hence, both I and II follows.

Consider the following least possible Venn diagram,

Conclusions:

I. No ear is nose → True. (definite true as all ears are hands and no hand is nose)

II. All noses are ears → False. (definite false as all ears are hands and no hand is nose)

III. Some hands are noses → False. (definite false as no hand is nose)

Hence, only I follows.

The pattern used here is,

Hence, QCJIW is the correct answer.

Here, if A is 1, B is 2, C is 3 and so on Z will be 26.

The code used here is three less than the sum of the numbers which comes in place of each letter i.e.

RUN → R = 18, U = 21, N = 14 → (18 + 21 + 14) - 3 = 53 - 3 = 50.

BUS → B = 2, U = 21, S = 19 → (2 + 21 + 19) - 3 = 42 - 3 = 39.

Similarly,

GUN → G = 7, U = 21, N = 14 → (7 + 21 + 14) - 3 = 42 - 3 = 39.

Here the pattern followed in each column is :

3^rd number × 1^st number + 2^nd number = 4^th number

In column 1 → 4 × 3 + 6 = 18

In column 2 → 8 × 2 + 5 = 21

Similarly,

In column 3 → 7 × 3 + 1 = 22

Hence, 22 is the correct answer.

In the above 2 × 2 matrices the sum of all the four numbers of a matrix is 19 i.e.

In matrix 1 → 2 + 3 + 8 + 6 = 19

In matrix 2 → 4 + 4 + 2 + 9 = 19

Similarly,

In matrix 3 → 12 + 2 + ? + 3 = 19 → ? = 19 - 17 = 2

Hence, the correct answer is 2.

The pattern used here is the number inside the triangle is obtained by multiplying the numbers on its vertices i.e.

3 × 4 × 7 = 84

5 × 3 × 2 = 30

Similarly,

7 × 2 × 5 = 70

Hence, 70 is the correct answer.

The pattern used here is the square of natural numbers are written in clock wise starting from 1 i.e.     

1² = 1

2² = 4

3² = 9

4² = 16

5² = 25

6² = 36

Hence, 36 is the correct answer.

The diagram below shows the path followed by Suman,

Clearly we can see that the end point is in the east direction from her starting point.

According to the question the relation between the ages of A, B, C, D and E are

A = B + 2

B = C - 5

C = D + 3

D = E - 6

Let the age of E be 10 years

D = 10 - 6 = 4 years

C = D + 3 = 4 + 3 = 7 years

B = C - 5 = 7 - 5 = 2 years

A = B + 2 = 2 + 2 = 4 years

Hence, B is the youngest.

1. R is sitting at south end and S is sitting at north end.

2. T is neighbour of Q and R. P and Q are sitting together.

Hence, Q is sitting in the middle.

According to the questions the relation between the weights of P, Q, R, S, and T are

$\begin{array}{l} P = 2Q\ Q = \frac{1}{2}R\ R = 3T\ T = \frac{1}{2}S \to S = 2T \end{array}$

Let the weight of T be 10kg

S = 2T = 20kg

R = 3T = 30kg

$Q = \frac{1}{2}R = \frac{1}{2} \times 30 = 15kg$

P = 2Q = 2 × 15 = 30 kg

Therefore, the weight of Q is greater than T only.

Hence, option 3 completes the pattern in question figure.

The question figure is hidden in the following figure.

The mirror image of the question will be : 

Hence, we can say that option 4 is the correct mirror image of the given question.

Let us check each option one by one :

1. In the option figure 6 and 4 are adjacent faces which is not possible as after folding the cube 6 and 4 will be opposite faces.

2. In the option figure 5 and 3 are adjacent faces which is not possible as after folding the cube 5 and 3 will be opposite faces.

3. In the option figure 1, 3 and 4 are adjacent faces which is possible as after folding the cube 1, 3 and 4 will form adjacent faces.

4. In the option figure 2 and 1 are adjacent faces which is not possible as after folding the cube 2 and 1 will be opposite faces.

Hence, cube of option number 3 can be formed by folding the figure given in the question.

Let’s check all the options,

1. 58, 40, 86, 34 → PAHR

2. 76, 55, 89, 23 → PNNK

3. 23, 78, 34, 02 → KARK

4. 95, 40, 77, 65 → PARK

Thus the correct option is 95, 40, 77, 65.

The correct answer is Electrical impulses.

The basic unit of the brain is the neuron and neurons exchange signals in the form of electrical impulses through axons and dendrites.

The detailed process is:

• The receptor detects a stimulus.
• Sensory neurons send electrical impulses to a relay neuron located in the spinal cord.
• Relay neurons connect sensory neurons to motor neurons.
• Motor neurons send electrical impulses to an effector.
• Effector produces a response.

Additional Information

Receptor→sensory neuron→spinal cord→motor neuron→effector

• A reflex arc is a neural pathway that controls a reflex action. Invertebrates, instead of passing directly to the brain, the sensory neuron's synapse in the spinal cord.
• This helps in a faster reflex action without the delay that is caused by routing signals through the brain.
• The three main types of neurons are sensory, motor, and relay neurons.

Genes are sequences of DNA or RNA that are related to heredity in animals. The study of this branch is known as genetics.

Explanation:

• Lysosomes are known as suicidal bags due to their Hydrolytic enzymes. These enzymes can lead to the self-destruction of the cell when the lysosomes burst and release their content into the cell, digesting its components.
• "suicidal bags" when referring to lysosomes comes from their hydrolytic enzymes which facilitate self-destruction under certain circumstances, not from their phagocytic activity.
• While it is true that lysosomes play a crucial role in phagocytosis, the process of engulfing and degrading foreign particles or pathogens. this is not the feature that earned them the "suicidal bags" name. It's their hydrolytic enzymes that, under conditions of cellular damage or stress, may be released into the cell, causing autolysis or "cell suicide"

So, based on these sources, the answer would still be "3) Hydrolytic enzymes".

Detoxification refers to the physiological removal of toxic substances from the human body and it is carried out by liver.

Additional Information

Correct option:1) Since the latter part of the sentence conveys that the attempts have already failed, the error is in the first part of the sentence (has becoming). The correct form of the verb ‘become’ should be ‘has become’.

Thus the correct sentence is:

It has become clear that attempts to impress the people have failed.

Correct option: **2)**The error lies in the second part of the sentence. The usage of ‘had’ is incorrect as the sentence is in the present tense. The correct word to be used is ‘has’.

Therefore, the correct sentence is:

A raise is important since one has to beat rising prices.

Here the correct answer is 1.

Key Points

• The fault is in part 1 of the sentence due to the presence of preposition ‘in’.
• The verb committed takes the preposition ‘to’ with it.
• For Example - Jana won an academic award after committing herself to her studies.
• Thus, the correct answer is Option 1.

Hence, the correct sentence is: We are committed to providing you a safe and comfortable travel experience.

Hinglish

• Preposition 'in' की उपस्थिति के कारण वाक्य के भाग 1 में दोष है।
• Verb 'committed' के साथ preposition 'to' का उपयोग होता है।
• उदाहरण के लिए - Jana won an academic award after committing herself to her studies.
• अत: सही उत्तर विकल्प 1 है।

अत: सही वाक्य है: We are committed to providing you a safe and comfortable travel experience.

Correct option: 3) The flaw is in the third part of the sentence. The fault is due to the presence of preposition ‘in’. It is always a ‘period of time’.

Hence, the correct sentence is:

Most of us have a desire to create wealth in the shortest period of time.

The correct answer is 2.

Key Points

• Using 'searching' in the place of 'search' to make the sentence correct.
• 'Began' is the 2^nd form of the verb 'Begin', we know that after the verb 'began' needs the objective case of 'noun or pronoun'.
• 'Searching' is the gerund form of the verb 'Search' and we know that gerund can act as a noun. So it is the most suitable here.
• Hence, option 2 is the most appropriate answer here.

The correct sentence is: Intrigued by this problem, I began searching for a solution. 

Additional Information

• A gerund is the '–ing' form of a verb that functions the same as a noun.
• For example, 'Running is fun.' (In this sentence, 'running' is the gerund. It acts just like a noun)

The correct answer is 4.

Key Points

• The sentence is grammatically and contextually correct.
• Hence, there is no error in the sentence.

Additional Information

• In first part of the sentence "is" is used correctly. Here "is" comes for something. In this structure "there' is used as an introductory there, so first part of the sentence is correct.
• In second part of the sentence the "in the store for" is also correct because it gives the contextual meaning of the sentence and here preposition 'for' is also correct.
• In third part of sentence only one word i.e. "everyone", itself correct to the contextual sense of the sentence.

The correct answer is '2'

Key Points

• In the given sentence, the usage of 'try' is incorrect instead of it use 'trying'
• According to grammar, whenever we use a preposition it always has a noun/pronoun/gerund after it. So in the given sentence 'try' is a verb hence we need to use a gerund after the preposition to make it a prepositional object.

So the correct sentence is- We might supply so much evidence in trying to explain it in so many ways.

The correct answer is 3.

Key Points

• The error is in the third part of the sentence. This sentence can be corrected in two ways
• We can either change it to 'spiritual benefits' or 'spiritually benefited'.
• 'Spiritually' is an adverb. An adverb is a word that qualifies a verb, adjective or another adverb. So 'spiritually benefited' is correct to use here.
• 'Spiritual is an adjective. An adjective is a word that qualifies a noun. So 'spiritual benefits' is also correct to use here.

Thus the sentence can be corrected as:

We hope devotees will participate in the event and get spiritually benefited.

                                             or

We hope devotees will participate in the event and get spiritual benefits.

Correct option: 2) The error is in the second part of the sentence due to wrong usage of ‘fell’. It should be ‘feel’ as it means to experience something.

The correct sentence is:

A lot of efforts may feel like they are going unnoticed.
