SSC CHSL Previous Paper 58 (Held On: 27 March 2018 Shift 3) (Previous Year Paper)

The correct answer is 2.

Key Points

• Part 2 of the given sentence has an error.
• Here we are comparing Kamleshwar reservoir (in the sanctuary) with other places.
• 'Best' the superlative degree of the adjective (good) is used in the sentence,
• Hence, we should use 'the' with the superlative degree of adjectives.
  

**Correct sentence: '**The Kamleshwar reservoir in the sanctuary is the best place to see the marsh crocodile.'

The correct answer is 1.

Key Points

• Part 1 of the given sentence has an error.
• 'While' is used in a sentence when a moment is happening, during. 
• Ex. He was watching me while running.
• 'When' at or on which (referring to a time or circumstance). 
• Ex. I used to do that stuff when I was young.
• Hence 'when' should be used in place of 'while', because the people of Orleans saw her at a particular time.
  

Correct sentence: 'The people of Orleans, when they first saw her in their city, thought she was an angel.'

The correct answer is Shoot down.

Key Points

• Shoot down is a phrasal verb of Shoot which means to kill or wound someone by shooting them, especially in a ruthless way.
• ​Ex. Police had to shoot him down, because of the threat he posed.
• Shot - The firing of a gun or cannon.
• Ex. Anup killed him with a single shot
• Shoot of is not a word.
• Hoot with is not a word, 
• ​Hoot - to shout or laugh usually derisively 
• Ex. T**he audience broke into hoots of laughter
• Hence, 'shoot down' should be used in the given space. 
  

**Correct sentence: 'The sniper was able to shoot down two rebels.'

The correct answer is Lived.

Key Points

• The given sentence is in past tense as the sentence starts with 'Once upon a time'.
• Hence, past participle of 'live'- 'lived' should be used.
• The given sentence is not progressive as there are no signs of auxiliary verbs like was/had been. Hence living cannot be used in the given space.
• Live is used in the simple present tense.
• Liven means make or become more lively or interesting. this meaning doesn't suit the given sentence. 
  

Correct sentence: '**Once upon a time there lived a dragon named Erasmus.'

• दिया गया वाक्य भूतकाल में है क्योंकि वाक्य 'Once upon a time' से शुरू होता है।
• अत: 'lived'- 'live' के past perfect tense का प्रयोग करना चाहिए।
• दिया गया वाक्य प्रगतिशील नहीं है क्योंकि सहायक क्रियाओं के कोई संकेत नहीं हैं जैसे was/had been। इसलिए दिए गए स्थान में living का उपयोग नहीं किया जा सकता है।
• Live  का प्रयोग simple present tense में किया जाता है।
• Liven का अर्थ है अधिक जीवंत या दिलचस्प बनाना या बनना। यह अर्थ दिए गए वाक्य के अनुकूल नहीं है।

सही वाक्य : Once upon a time there lived a dragon named Erasmus.

Here, Pattern is such that second word is a place or area which is fully surrounded by the first word i.e.

Sand : Desert → Desert is a place which is fully surrounded by sand.

Let’s check all the options.

Ocean : Water → Here water is not fully surrounded by ocean.

Pond : Water → Here water is not fully surrounded by pond.

Eat : Smoke → Here smoke is not fully surrounded by eat.

Water : Sea → Here sea is a place which is fully surrounded by water.

Hence, Water : Sea is the correct alternative.

Here pattern is such that 2^nd number is 5 more than the 1^st number i.e.

33 : 38 → 33 + 5 = 38.

Let’s check all the options

17 : 24 → 17 + 5 = 22 ≠ 24.

12 : 18 → 12 + 5 = 17 ≠ 18.

10 : 20 → 10 + 5 = 15 ≠ 20

13 : 18 → 13 + 5 = 18 = 18

Thus, 13 : 18 is the correct alternative.

The pattern here is as follows,

Therefore, FGJ is the correct alternative.

In all of the above pair clearly Carnivorous - Bear is the odd one because in all the above options the animals are vegetarian i.e. herbivorous animals while bear is the only carnivorous i.e. non-vegetarian

Thus, Carnivorous - Bear is the odd pair.

Out of the given options, 27 - 22 is odd one because in all other options 2^nd term is 3 less than the 1^st term i.e.

15 - 12 → 15 - 3 = 12

21 - 18 → 21 - 3 = 18

25 - 22 → 25 - 3 = 22

But in 27 - 22 → 27 - 3 = 24 which is not equal to 22.

Thus, 27 - 22 is odd one.

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

Hence, JLP is the odd one.

The dictionary sequence is:

Massive → Match → Measure → Metal → Method.

Thus, Measure will come at THIRD position.

The relation between the numbers is as follows,

26 × 0.5 + 0.5 = 13.5

13.5 × 1 + 1 = 13.5 + 1 = 14.5

14.5 × 2 + 2 = 29 + 2 = 31

31 × 4 + 4 = 124 + 4 = 128

128 × 8 + 8 = 1024 + 8 = 1032

Hence, the next number is 1032.

The pattern is as follows,

Hence, the next term is E.

In a row of boys, Rahul is 31^st from top and Vinod is 53^rd from the bottom and there are 22 boys between Vinod and Rahul. So, there are two possible arrangements which are shown in the diagram below:

We have to find the minimum students. So, Case I is eliminated. We have case II as the valid case.

Now there are 30 boys above Rahul out of which 22 are those who are between Rahul and Vinod and 1 is Vinod himself. Hence, boys above Vinod = 30 - 23 = 7.

Again there are 52 boys behind Vinod out of which 22 are those who are between Rahul and Vinod and 1 is Rahul himself. Hence, boys behind Rahul = 52 - 23 = 29.

So, minimum number of boys = 29 + 22 + 7 + 2 = 60

Number of girls = 15

Hence, Minimum number of students = 60 + 15 = 75.

Let’s check each option,

1. FORM → can be formed from MISINFORMATIVE.

2. MOTIVE → can be formed from MISINFORMATIVE.

3. INFORM → can be formed from MISINFORMATIVE.

4. MANY → cannot be formed because there is no ‘Y’ in MISINFORMATIVE.

Hence, MANY can’t be formed from word MISINFORMATIVE.

The pattern here is each letter of the given two words is coded with a number which is its place value in English alphabet as shown below

Hence the required conversion is,

Hence, 31181215 is the correct alternative.

The given equation is: 10 ÷ 4 - 10 + 6 × 2 = ?

Here ‘-’ represents ‘+’, ‘+’ represents ‘×’, ‘×’ represents ‘÷’ and ‘÷’ represents ‘-’. So let’s replace the sign in the above equation.

10 ÷ 4 - 10 + 6 × 2 →

10 - 4 + 10 × 6 ÷ 2

= 10 - 4 + 10 × 3

= 10 - 4 + 30 

= 40 - 4

= 36

Hence, 36 is the correct alternative.

The given equation is: 18 ÷ 2 × 4 + 10 - 2 = 25

Let’s check each option,

1. ÷ and - → 18 - 2 × 4 + 10 ÷ 2 = 15 ≠ 25

2. • and ÷ → 18 + 2 × 4 ÷ 10 - 2 = 16.8 ≠ 25
3. • and + → 18 ÷ 2 × 4 - 10 + 2 = 28 ≠ 25

4. × and - → 18 ÷ 2 - 4 + 10 × 2 = 25 = 25

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

The pattern here is as follows, two numbers are given separated by ‘#’. We get the answer by adding the two numbers and dividing it by 2 to get the answer.

Let A and B are two numbers such that A # B then

A # B = (A + B) ÷ 2 i.e.

6 # 2 = (6 + 2) ÷ 2 = 8 ÷ 2 = 4

2 # 6 = (2 + 6) ÷ 2 = 8 ÷ 2 = 4

14 # 12 = (14 + 12) ÷ 2 = 26 ÷ 2 = 13

Similarly, 4 # 24 = (4 + 24) ÷ 2 = 28 ÷ 2 = 14.

Hence, 14 is the correct alternative.

The pattern here is the letter ‘C’ is interchanging its position with the letter on its immediate right in every step i.e.

CBABABABA, BCABABABA, BACBABABA, BABCABABA, BABACBABA, BABABCABA.

Hence, BABABCABA is the correct alternative.

The diagram below shows the route taken by the woman,

Clearly, we can see that the market is 3 - 2 = 1 km in North direction from her hut.

Consider the following least possible Venn diagram,

Conclusions:

I. Some tobacco are cigars → False (It is possible but not definite hence false).

II. All cigars are tobacco → False (It is possible but not definite hence false).

Hence, neither conclusion I nor conclusion II follows.

Here, rectangle represents Film directors, circle represents Bikers, triangle represents Riders and square represents Asians.

Clearly, Film directors who are Riders is represented by the intersection of rectangle and triangle i.e. BC.

Hence, BC is the correct alternative.

The pattern is as follows,

Hence, the next term is SBX.

The relation between the numbers is as follows,

97 - (6 × 1) = 97 - 6 = 91

91 - (6 × 2) = 91 - 12 = 79

79 - (6 × 3) = 79 - 18 = 61

61 - (6 × 4) = 61 - 24 = 37

37 - (6 × 5) = 37 - 30 = 7

Hence, the next number is 7.

Out of the given options, (8, 25, 39) is odd one because in all other options 2^nd number is one less than thrice the 1^st number and 3^rd number is one less than five times the 1^st number i.e.

(5, 14, 24) → 5 × 3 - 1 = 14 and 5 × 5 - 1 = 24.

(9, 26, 44) → 9 × 3 - 1 = 26 and 9 × 5 - 1 = 44.

(15, 44, 74) → 15 × 3 - 1 = 44 and 15 × 5 - 1 = 74.

But in (8, 25, 39) → 8 × 3 - 1 = 23 which is not equal to 25 and 8 × 5 - 1 = 39.

Thus, (8, 25, 39) is odd one.

The mirror image of the question will be:

Hence, we can say that option 2 is the correct mirror image of the given question.

If we consider face with “

” as centre and fold its surrounding faces inside, we find that face with “

” and “

” are opposite to each other, face with “

” and “

” are opposite to each other and face with “

” and “

” are opposite to each other.

Here, cube in option 2 of the answer figure cannot be made based on the unfolded cube in the question because face with “

” and “

” are opposite to each other which is shown adjacent in option 2.

Hence, Option 2 is the correct alternative.

Let’s check all the options,

1) 11, 30, 75, 43 → FANG

2) 41, 59, 10, 69 → IXCX

3) 44, 89, 11, 68 → IYFW

4) 22, 67, 40, 78 → LPMY

Thus, the correct option is 11, 30, 75, 43.

Computing the factorials,

⇒ 1! = 1

⇒ 2! = 1 × 2 = 2

⇒ 3! = 1 × 2 × 3 = 6

⇒ 4! = 1 × 2 × 3 × 4 = 24

⇒ 5! = 1 × 2 × 3 × 4 × 5 = 120

As we can notice that the unit digit of 5! Is 0, hence, the unit digit of 6!, 7!, …, 50! will be zero

Unit's digit of (1! + 2! + 3! + 4! + …………… + 50!)

⇒ Unit's digit of (1! + 2! + 3! + 4!)

⇒ Unit's digit of (1 + 2 + 6 + 24)

∴ Unit's digit of (33) = 3

Alternate Method 1! = 1

2! = 2

3! = 6

4! = 24

5! = 120

∴ Unit digit = 1+ 2+ 6 + 4 + 0  = 13 = 3

Calculation:

All the digits of (10⁶ – 12) are 9, except the last two digits

The last two digits of (10⁶ – 12) = 100 – 12 = 88

When 88 is divided by 9, the remainder is 7

∴ The remainder when (10⁶ – 12) is divided by 9 is 7

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

Given,

⇒ 25^{x + y} = 1

⇒ 25^{x + y} = 25⁰

⇒ x + y = 0

⇒ y = – x       ----(1)

Also,

⇒ 3^{4x + y} = 1/27

⇒ 3^{4x + y} = 1/3³

⇒ 3^{4x + y} = 3^-3

⇒ 4x + y = –3

Substituting from (1),

⇒ 4x – x = –3

⇒ x = –3/3 = –1

⇒ y = –(–1) = 1

∴ xy = 1(–1) = –1

Given:

a + b + c = -7 + 5 + 2 = 0

Concept used:

As we know, (a³ + b³ + c³ – 3abc) = (a + b + c)(a² + b² + c² – ab – bc – ca)

Calculation:

If (a + b + c) = 0, then a³ + b³ + c³ = 3 abc

∴ a³ + b³ + c³ = 3(-7)(5)(2) = -210

When the distance between the circles is equal to the sum of their radii, it means that the two circle touch each other externally, as shown below

∴ A maximum of 3 common tangents can be drawn to the circles

When two circles touch each other internally, only one common tangent can be drawn to them, as shown below

Shortcut Trick

Difference in percentages = 50% − 20% = 30%

Difference in marks = 4 − (−11) = 15 marks

30% = 15 marks ⇒ 1% = 0.5 marks

Passing marks = (20% of Total Marks) + 11 = (20 × 0.5) + 11 = 21 marks

∴ The correct answer is 21.

Alternate Method

Given:

Marks scored at 20% = Passing Marks − 11

Marks scored at 50% = Passing Marks + 4

Formula Used:

Marks Scored = (Percentage ÷ 100) × Total Marks

Calculations:

⇒ Let the Total Marks be x.

⇒ 20% of x + 11 = 50% of x − 4

⇒ 0.20x + 11 = 0.50x − 4

⇒ 11 + 4 = 0.50x − 0.20x

⇒ 15 = 0.30x

⇒ x = 15 ÷ 0.30 = 50

⇒ Passing Marks = (20% of 50) + 11

⇒ Passing Marks = (0.20 × 50) + 11 = 10 + 11 = 21

∴ The correct answer is 21.

Additional Information

Passing Percentage

It is the minimum percent required to pass: (Passing Marks ÷ Total Marks) × 100.

Percentage Change Formula

Percentage difference between two results = (Difference in Marks ÷ Total Marks) × 100.

Total Marks Calculation

Total Marks = (Difference in Marks ÷ Difference in Percentages) × 100.

Given:

Ratio of 1 rupee, 50 paise and 25 paise = 5 : 3 : 1

Total number of coins = 180

Calculation:

Let, the number of coins of 1, 0.5, and 0.25 are 5x, 3x, and 1x respectively.

Hence, 5x + 3x + x = 180     ---- (1)

⇒ 9x = 180

⇒ x = 20

Hence, the number of 1 rupee coins = 5 × 20 = 100

Number of 50 paisa coins = 3 × 20 = 60 

Number of 25 paisa coins = 20

∴ Total value (in Rs.) = 1 × 100 + 0.5 × 60 + 0.25 × 20 = 135

Calculation:

Percentage of alcohol in Rahul’s mixture = [2/(2 + 6)] × 100 = 25%

Percentage of alcohol in Dinesh’s mixture = [1/(1 + 9)] × 100 = 10%

∴ Required ratio = 25 ∶ 10 = 5 ∶ 2

Formula used:

Average = Sum of the observation ÷ no. of observation

Calculation:

Average of (d, e) – Average of (e, h) = 19

⇒ (d + e)/2 – (e + h)/2 = 19

⇒ d + e – e – h = 19(2)

⇒ d – h = 38

∴ Difference between d and h = 38

Given:

R = 7.5%

Formula used:

Simple interest = (Principal × Rate × Time)/100

Let Principal = P, Time = T

⇒ (3/5)P = (P × 7.5 × T)/100

⇒ T = 60/7.5 = 8 years

∴ Time period = 8 years

Calculation:

Let the SP of the article be Rs. 100.

CP = 35% of 100 = Rs. 35

Profit = 100 - 35 = Rs. 65

Profit % = (65/35) × 100 = 185.71%

∴ The profit percentage is 185.71%

Given:

Marked price of shirt = Rs. 10400

Calculation:

Discount price = 20% of Marked price = 0.2 × 10400 = Rs. 2080

Selling price of shirt = Marked price – Discount price = 10400 – 2080 = Rs. 8320

Profit earned = 30% of Cost price

∵ Cost price + Profit = Selling price

⇒ (100 + 30)% of Cost price = 8320

⇒ Cost price of shirt = 8320/1.3 = Rs. 6400

If no discount is given, then selling price = marked price = Rs. 10400

∴ Profit = [(10400 – 6400)/6400] × 100 = 62.5%

Considering statement I,

⇒ 2√26 > 3√35

Squaring both sides,

⇒ 4(26) > 9(35)

⇒ 104 > 315, which is not true

Considering statement I,

⇒ 3√37 > 4√50

Squaring both sides,

⇒ 9(37) > 16(50)

⇒ 333 > 800, which is not true

∴ Neither statement I nor II is true

Let Y take ‘n’ days to complete the wall alone

Time taken by X = (100 + 20)% of n = 1.2n

X’s 1 day work = 1/1.2n = 5/6n

Y’s 1 day work = 1/n

When they work together, they complete the wall in 30 days,

⇒ X’s 1 day work + Y’s 1 day work = 1/30

⇒ 5/6n + 1/n = 1/30

⇒ 11/6n = 1/30

⇒ n = (11 × 30)/6 = 55 days

∴ Y will take 55 days to complete the wall alone

Given:

Distance = 20 km

Time = 15 minutes

Calculation:

Speed of car = Distance/Time = 20/(15/60) = 80 km/hr

When speed is decreased by 10 km/hr,

Speed of car = 80 – 10 = 70 km/hr

∴ Time taken to cover same distance = 20/70 = 2/7 hrs = (2/7) × 60 = 120/7 minutes

Calculation:

Value of milk = 1000 crores

Value of soya = 250 crores

Value of rice = 200 crores

Value of wheat = 900 crores

Value of sugarcane = 950 crores

Value of pulses = 800 crores

Value of corm = 400 crores

Here, we can see that 1000 crores is the most

∴ Value of milk is the most

Calculation:

Total value of annual production (in crores) = 1000 + 250 + 200 + 900 + 950 + 800 + 400

= Rs. 4500

Annual production of Milk = Rs. 1000 crore

Total annual production = Rs. 4500 crore

∴ Central angle of sector representing the production of Milk = (1000/4500) × 360° = 80°

Annual production of Wheat = Rs. 900 crores

Value of Wheat per tonne = Rs. 15000

∴ Wheat produced = (900 × 10⁷)/15000 = 600000 tonnes

Given:

Breadth = 5 cm

Length = 12 cm

Concept used:

∵ Perimeter of rectangle = 2(length + breadth)

Calculation:

∴ Perimeter of given rectangle = 2(12 + 5) = 2(17) = 34 cm

For a regular polygon with n sides,

Sum of interior angles = (n – 2) 180°

∴ Sum of interior angles of a regular polygon with 8 sides = (8 – 2) × 180° = 1080°

∵ Volume of a cuboid = length × breadth × height

∴ Volume of given cuboid = 7.5 × 5 × 6 = 225 cm³

Given:

∆DEF, ∠E = 90° and ∠D = 60°

Concept used:

Sum of angles of a triangle = 180°

Calculation:

⇒ ∠D + ∠E + ∠F = 180°

⇒ 60° + 90° + ∠F = 180°

⇒ ∠F = 180° – 150° = 30°

∴ (cot F + 1/√3) = cot 30° + 1/√3 = √3 + 1/√3 = 4/√3

Given:

cot X = 3/4

Calculation:

In ∆XYZ shown below,

cot X = Adjacent side/Opposite side = XY/YZ = 3/4

∴ tan Z = Opposite side/Adjacent side = XY/YZ = 3/4

Here cot X = tan Z

The correct answer is Lignin

Explanation:-

• The cells of sclerenchyma tissue have their walls thickened due to the presence of Lignin.
• Sclerenchyma tissues are one of the fundamental tissues in the plants.
• These are the strengthening tissues in plants with lignified walls.

Sclerenchyma tissue:

• Sclerenchyma support tissue is composed of various kinds of hard woody cells.
• Mature cells are usually dead that have heavily thickened secondary walls containing lignin.
• Sclerenchyma cells occur in different shapes and sizes, its two main types are fibres and sclereids
• Fibres are greatly elongated cells whose long, tapering ends interlock each other thus providing maximum support to a plant.
• Sclereids are variable in shape and are present in various tissues of the plant, such as the periderm, cortex, pith, xylem, and phloem.

Additional Information Parenchyma, tissue is composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions.

Aerenchyma tissue contains enlarged gas spaces.

• It is formed either as part of normal development or in response to stress.

Collenchyma supports the tissue of living elongated cells with irregular cell walls.

• These cells have thick deposits of cellulose in their cell walls and appear polygonal in cross-section.

CONCEPT**:**

• Resistance: The property of electrical materials and electrical instruments that opposes the flow of current through them is called resistance.
• It is denoted by R.
• The SI unit of resistance is the ohm (Ω).
• Power: The rate of work done by an electric current is called power.
• It is denoted by P.
• The SI unit of power is the watt (W).
• Power dissipation is given by:

Power (P) = V I = V2/R = I2 R

Where V = potential difference across resistance, I = current flowing and R = resistance.

CALCULATION:

Given that:

Current (I) = 0.1 A

Potential difference (V) = 250V

• The power rating of the bulb (in Watt) is

⇒ P = V I

⇒ P = 250 × 0.1 W = 25 Watt

EXPLANATION:

The density of particles is more in solid and sound travels the fastest in it, thereby creating more pressure in the process. That is why the loudness is also the most in a solid medium.

The correct answer is Winds.

Key Points

• The wind is the movement of air, caused by the uneven heating of the Earth by the sun and the Earth's own rotation. Winds range from light breezes to natural hazards such as hurricanes and tornadoes.
• Differences in atmospheric pressure generate winds.
• At the Equator, the sun warms the water and land more than it does the rest of the globe.
• Warm equatorial air rises higher into the atmosphere and migrates toward the poles. This is a low-pressure system.
• At the same time, cooler, denser air moves over Earth’s surface toward the Equator to replace the heated air. This is a high-pressure system.
• Winds generally blow from high-pressure areas to low-pressure areas.
• Prevailing winds are winds that blow from a single direction over a specific area of the Earth.
• Areas, where prevailing winds meet, are called convergence zones.
• Generally, prevailing winds blow east-west rather than north-south.
• This happens because Earth’s rotation generates what is known as the Coriolis effect.
• The Coriolis effect makes wind systems twist counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
