SSC CHSL Tier-1 2021: Official Paper (Held On : 27 May 2022 Shift 2) (Previous Year Paper)

The correct answer is: Pseudo.

Key Points

• Pseudo means pretended and not real (दिखावा करना ; वास्तविक नहीं)

                • Example- Her care for the poor is completely pseudo. 

• Marked option Genuine means things are authentic. (चीजें जो प्रामाणिक हैं।)

                • Example- This ring is genuine gold.

• It is clear that Pseudo and Genuine are opposite in meaning.

Therefore the correct answer is option 2.

 

Additional Information

• Flawed means an imperfection or weakness and especially one that detracts from the whole or hinders. (एक अपूर्णता या कमजोरी और विशेष रूप से एक जो पूरी तरह से अलग हो जाती है या बाधा डालती है।)
• Artificial means not genuine or natural but made by people. (वास्तविक या प्राकृतिक नहीं बल्कि लोगों द्वारा बनाया गया)
• Corrupt means doing or involving illegal or dishonest things in exchange for money, etc. (पैसे ���दि के बदले में अवैध या बेईमान चीजें करना या शामिल करना।)

The segment that contains a grammatical error is 'fastly above'.

Key Points

• ‘Fastly’ is not correct.
• The word ‘fast’ is used in the same form in adjectives and in adverbs.
• Generally, we add ' ly' to the adjectives to change them into adverbs.
• But there are certain words that can be used as adjectives as well as adverbs without adding 'ly'. Eg: ‘ fast, straight, enough, etc. ‘
• Examples-  • He ran fast. (adverb)

                              •They like fast cars and expensive restaurants. (adjective)

So, the right sentence is**:** The birds flew fast above us as we stood on our terrace.

The correct answer is option 3.

The correct answer is: She said that she could play the guitar pretty well.

Key Points

• The given sentence is in direct speech and we need to convert it to indirect speech.
• When we change a direct speech to indirect speech, we must follow these rules:

​                • The reporting verb 'said' remains unchanged.

                • The inverted commas ("...") are replaced with the conjunction 'that' to show the indirect speech.

                • A comma (,) that is added after the direct speech part, should be removed in the indirect speech.

                • The modal 'can' changes to 'could'.

                • 'I' changes to 'she'.

• Thus, option 3 is the correct answer.

Hence, The Indirect speech is- She said that she could play the guitar pretty well.

The correct answer is 'discontinues'.

Key Points

• Persist means to continue to exist or occur without interruption. (बिना किसी रुकावट के मौजूद रहना या घटित होना।)

                  • Example- If the fool would persist in his folly he would become wise.

• Discontinue means to stop something or stop producing something. (किसी चीज़ को रोकना या किसी चीज़ का उत्पादन बंद करना)

                  • Example- He discontinued his visits to the psychiatrist.

• So, it is clear that 'Persist' and 'Discontinue' are opposite in meaning.

We have to try the options on the given equation:

    25 * 5 * 10 * 2 * 8 * 56

Using BODMAS rule :- Bracket of Division Multiplication Addition Subtraction.

 Option 1) ÷, ×, +, –, =

25 ÷ 5 × 10 + 2 - 8 = 56

5 × 10 + 2 - 8 = 56

50 + 2 - 8 = 56

52 - 8 = 56

44 = 56  Incorrect

Option 2) –, +, ÷, ×, =

25 - 5 + 10 ÷ 2 × 8 = 56

25 - 5 + 5 × 8 = 56

25 - 5 + 40 = 56

65 - 5  = 56

60 = 56  Incorrect

Option 3) ×, ÷, –, +, =

25 × 5 ÷ 10 - 2 + 8 = 56

25 × 0.5 - 2 + 8 = 56

12.5 - 2 + 8 = 56

20.5 - 2 = 56

18.5 = 56  Incorrect

Option 4) ÷, ×, –, +, =

25 ÷ 5 × 10 - 2 + 8 = 56

5 × 10 - 2 + 8 = 56

50 - 2 + 8 = 56

58 - 2 = 56

56 = 56  Correct

 Hence the correct answer is option 4.

The pattern followed in the given terms are:

 The first and third characters are interchanged & fifth and seventh characters are interchanged.

 FLOWERS becomes OLFWSRE 

 

HOSTILE becomes SOHTELI 

 

 IMPORTS becomes PMIOSTR

Hence, the correct answer is option 3.

The answer is option 1)

SOLUTION:

When we unfold the paper once we get the mirror image of :

  

The mirror image of this pattern will be:                   

Now to get the complete unfolded pattern, which will be the mirror image of the last pattern:  

Hence the correct answer is option 1)

The relation between two consecutive term is :

The difference between first and the second term is 217.

Let's apply the pattern on the given series:

375 : 592 

592 - 375 = 217 

423 : 640 

640 - 423 = 217 

198 : ?

 ? - 198 = 217 

 ? = 217 +198 

 ? = 415

Hence the correct answer is 415.

The pattern in the given series can be determined by:

Hence the correct answer is 332.

In the given figure we can observe the pattern:

• The diamond moves in clock wise direction and turns solid after every alternate step.
• The triangle moves in clock wise direction and it is following the diamond.
• The circle inside the triangle turns solid after every alternate step.

​

Next step:

• As the last block shows the diamond downwards, it will appear upwards in the next step due to the clockwise motion and the triangle will not be solid because it was solid in the last step.
• The triangle will face upwards as it follows the movement of diamond.
• The circle will be solid because of it's alternate behavior.

So the pattern with the next step will be :

Hence the correct answer is option 2)

We take the difference between the numbers:

Note: Add prime number series 13,17, 19, 23, 29, 31 and 37. 

Hence the correct answer is 595.

Logic: (First term × 4) - 7 = Second term 

In 56 : 217

 (56 × 4) - 7 = 217

 (224) - 7 = 217 

  217 = 217 

In 73 : 285

 (73 × 4 ) - 7 = 285

 (292) - 7 = 285 

  285 = 285

In 38 : ? 

 (38 × 4 ) - 7 = Second term 

 (152) - 7 = Second term 

  145 = Second term

Hence, the correct answer is 145.

When we observe the given image we can easily locate the triangles present in it:

• 

      4 + 4 + 2 = 10 

Hence the correct answer is 10.

Alphabetical Order with its placed value:

The pattern followed in the given series is:

 On continuing the pattern we get the next cluster, 

Hence, the correct answer is UGJN.

The pattern in the following series:

  13 × 21 = 273 

Hence the correct answer is 273.

Alternate Method7 x (7 + 8) = 7 x 15 = 105

9 x (9 + 8) = 9 x 17 = 153

13 x (13 + 8) = 13 x 21 = 273

Given: 11 July 2020 was Monday.

Important Points

• Here, 11 July 2020 has been given as Monday  - this does not match the original weekday of this date. Hence, the day on 14 October 2028 is also not similar to the original weekday.
• Therefore, 14 October 2028 will not be a Saturday if 11 July 2020 is a Monday.

So, 11 July to 14 October = 20(July) + 31(Aug) + 30(Sep) + 14(Oct)

= 95 days = 95/7 = 13 weeks and 4 odd days.

So, 14 October 2020 = Monday + 4 = Friday.

Now, 

14 October 2020 to 14 October 2028 = 8 Years.

 

8 Years (6 Ordinary Year + 2 Leap Year) = 6 + 4 = 10 odd days.

10 odd days = 10/7 = 1 week 3 odd days.

So, 14 October 2028 = Friday + 3 = Monday.

Hence, the correct answer is "Monday".

Alternate Method

Year : 2028 - 2020 = 8 years + 2 leap years = 10 years , odd days = 3 

 Month: July-3, Aug-3, Sep-2 = 8 , odd days =1 (Oct will not be counted)

Date: 22-14 = 8, odd days = 1

total odd days = 3 + 1 + 1 = 5 , odd days = 0

Therefore, Monday + 0 = Monday    

Hence, the correct answer is Monday.

Alphabetical order with its placed value:

The pattern in the given series is:

The letters are increased to 1 positional value and the code word is arranged backwards:

PUNCH becomes IDOVQ

CRACK becomes LDBSD

BREAK becomes LBFSC

Hence the correct answer is LBFSC.

Family chart:

According to the statement:

She is Rashmi's mother.

Hence, 'option 1' is the correct answer.

In a standard dice the faces 2 and 5 are opposite & 3 and 4 are opposite & 1 and 6 are opposite to each other.

The side opposites to each other in a dice are:

     

The dice is turned to it's right keeping the face '1' at the same position.

We found that '3' is to the right of '5' and '4' is to the left of '5'. Thus, 3 is opposite to 4.

Therefore 5 is opposite to 2.

The only two faces left are '1' and '6'. So 1 is opposite to 6.

 

So the sum of side opposite to 5 and 1 is: 

  Side opposite to 5 + side opposite to 1 = 6 + 2 = 8 

Hence the correct answer is 8.

From the given information:

Step 1: A is shorter than B but taller than C.

⇒ B > A > C​

Step 2: E is taller than G but shorter than C.

⇒ C > E > G

Step 3: D is taller than B but shorter than F.

⇒ F > D > B

Combining the given information:

⇒ F > D > B > A > C > E > G

So, F is the tallest.

Hence the correct answer is option 3)

The pattern applied in the given series is: 

Thus you can clearly see that there are two cases alternatively followed, first a number is multiplied by two and as we further go on it , it will be multiplied by next number by keeping a common multiple of 2 and in next case subtracted by an odd number in a succeeding manner from the previous cases.

Hence the answer will be option 4)

If you see the question properly the paper  has been folded  symmetrically from the middle  and then again through the line.

This will divide the figure into four squares and each square will contain 3 circles along the adjacent sides, when the paper will be folded the circles should overlap each other which can be only seen in Option 4 while all the other three options are asymmetrical.

Thus the correct answer is option 4)

Lets see the statements;

All pillows are beds.

No table is a bed.

Some tables are chairs.

Now we consider the given conclusions:

I. No pillow is a table: From the diagram and the given statement we can say that there is no relation between pillow and table and thus we can say that no pillow is a table. So the conclusion follow.

II. Some chairs are pillows: From the diagram and the given statement we can say that there is no relation between pillow and chairs also chairs are not related to bed so there is no possibility and thus we cannot say that some chairs are pillows. So the conclusion does not follow.

III. No bed is a chair: There is no information that relates bed with chairs and we already know chairs are not related to pillows either so there is no connection that leads us to this conclusion and therefore this conclusion does not follow.

Since only conclusion I follows.

Hence the correct answer is option 2)

The logic is followed here:

Sum of all numbers = Multiplication of first two numbers

First row: 5,6,19

⇒ 5 × 6 = 5 + 6 + 19 

⇒ 30 = 30

Second row: 7,7,35

⇒ 7 × 7= 7 + 7 + 35

⇒ 49 = 49 

Third row: 8,9,?

⇒  8 × 9 = 8 + 9 + ?

⇒ 72 = 17 + ?

⇒ ? = 55

Here, the correct answer is 55.

Alternate Method The applied logic is:

In a given row the first two numbers are multiplied and subtracted with the third number which will give the obtained number thus as we go on to the next row the obtained value increases by three in each case, thus following the same logic, 

First row: 5,6,19

5 × 6 - 19 = 11

30 - 19 = 11

Second row:7,7,35

7 × 7 - 35 = 14

49 - 35 = 14

That is (11+3=14, FROM FIRST ROW)

Third row:8,9,?

8 × 9 - ?= (14 + 3)

72 - ? = 17

55 = Answer

Hence the correct answer is option 4)

In the given series:

 The pattern changes in rows and columns alternatively.

• In rows, the top row shift to middle, middle row shifts to bottom and bottom row shifts to top.
• In columns, the right column sifts to left, left shifts to middle and middle shifts to right.

​So the next step will be:

Now we consider the given options:

Option 1) The arrangement of rows are wrong.

Option 2) ) The pattern matches completely.

Option 3) The arrangement of rows and columns are wrong.

Option 4) The arrangement of rows are wrong.

Hence the correct answer is option 2)

From the given information:

M denotes ‘−’, N denotes ‘÷’, O denotes ‘×’ and P denotes ‘+’We substitute the values and solve the equation using BODMAS rule:

(16 O 7) P 124 M 92 P (86 N 43) O 18 M 29 = ?

(16 × 7) + 124 - 92 + (86 ÷ 43) × 18 - 29 = ?

112 + 124 - 92 + 2 × 18 - 29 = ?

112 + 124 - 92 + 36 - 29 = ?

272 - 92 - 29 = ? 

151 = Answer

Hence the correct answer is option 2)

The pattern followed here is:

Coded word = (Positional value of 1^st letter) × (Positional value of 2^nd letter) + 2

• In AN → 16 
• Positional value of A and N = 1 and 14
• Hence, coded word = (1 × 14) + 2 = 14 + 2 = 16
• In NO → 212 
• Positional value of N and O = 14 and 15
• Hence, coded word = (14 × 15) + 2 = 210 + 2 = 212
• Similarly, US → ? 
• Positional value of U and S = 21 and 19
• Hence, coded word = (21 × 19) + 2 = 399 + 2 = 401

Hence, Option 3) is the correct answer.

According to the English alphabet and their positional values:

Given: 

45% voted for A, 35% voted for B and the remaining 20% voted for C.

30% of the votes polled for A and 20% of the votes polled for B were later deemed invalid,

A got 882 more valid votes than B 

Calculations:

According to the question,

Let the total votes be 'x'

882 = (Valid votes of A) - (Valid votes of B)

⇒ 882 = (70% of 45% of 90% of x) - (80% of 35% of 90% of x)

⇒ 882 = (x × 90 × 10 × 5)/1000000 (7 × 9 - 8 × 7)

⇒ 882 = (4500x)/1000000 × (63 - 56)

⇒ 882 = (45x)/10000 × (7)

⇒ x = (882 × 10000)/(7 × 45)

⇒ x = 14 × 2000 = 28000 votes

Now, valid votes did C recieve

Votes of C = 20% of 90% of valid votes

⇒ Votes of C = 20% × 90% × 28000 

⇒ Votes of C = 0.20 × 0.90 × 28000 

⇒ Votes of C = 0.20 × 25200 = 5040 votes

∴ Valid votes of C is 5040.

Given:

∴ The difference in the number of type B geysers sold in 2010 and 2012 is 44000 units.

Shortcut Trick

Relative speed of the policeman = 10.5 − 8 = 2.5 km/h.

Distance covered in 60 min (1 hour) = 2.5 km = 2500 m.

Distance covered in 12 minutes = 2500 × (12 ÷ 60) = 500 m.

Remaining distance between them = 650 − 500 = 150 m.

∴ The correct answer is 150 m.

Alternate Method

Given:

Initial distance = 650 m

Speed of thief (v_t) = 8 km/h

Speed of policeman (v_p) = 10.5 km/h

Time (t) = 12 minutes

Formula Used:

Relative Speed (Same direction) = v_p − v_t

Distance = Speed × Time

Calculations:

⇒ Relative speed = 10.5 − 8 = 2.5 km/h

⇒ Converting speed to m/min: 2.5 × (1000 ÷ 60) = 125/3 m/min

⇒ Distance reduced in 12 min = (125 ÷ 3) × 12

⇒ Distance reduced = 125 × 4 = 500 m

⇒ Distance between them after 12 minutes = Initial Distance − Distance reduced

⇒ Final distance = 650 − 500 = 150 m

∴ The correct answer is 150 m.

Additional Information

Relative Speed in Same Direction

When two objects move in the same direction, the effective speed is the difference: Speed = v₁ − v₂.

⇒ 0.2962 × 100 = 29.62% or 29$\frac{{17}}{{27}}$%

∴ The quantity of wheat used in the month of July is 29.62% or 29$\frac{{17}}{{27}}$% of the total quantity of food items used in June.

Shortcut Trick

Use the Ratio Method for multi-factor Profit and Loss problems.

Price Ratio (CP : SP) → 100 : 105 = 20 : 21

Weight Ratio (Actual : Claimed) → 960 : 1000 = 24 : 25

Final Ratio (CP : SP) = (20 × 24) : (21 × 25) = 480 : 525 = 32 : 35

Profit % = (3 ÷ 32) × 100 = 9.375%

∴ The correct answer is 9.375%.

Alternate Method

Given:

Claimed Profit Percentage = 5%

Claimed Weight = 1000 g

Actual Weight = 960 g

Let the Cost Price (CP) of 1 g be ₹1.

⇒ CP of 1000 g = ₹1000

⇒ Claimed SP = ₹1000 + 5% of ₹1000 = ₹1050

⇒ Actual Weight sold = 960 g

⇒ Actual CP for Subir = ₹960

⇒ Actual Profit = SP − Actual CP = 1050 − 960 = ₹90

⇒ Actual Profit % = (Profit ÷ Actual CP) × 100

⇒ Actual Profit % = (90 ÷ 960) × 100

⇒ Actual Profit % = (3 ÷ 32) × 100 = 9.375%

∴ The correct answer is 9.375%.

Additional Information

Dishonest Dealer Formula

Profit % = [(True Value − False Value) ÷ False Value] × 100. This is used when only weight is manipulated.

Effective Profit with Price Hike

Net Profit % = [(100 + g₁) × (True Weight ÷ False Weight) − 100], where g₁ is the claimed profit percentage.

Shortcut Trick

By the Remainder Theorem, if a polynomial f(x) is divided by (ax + b), the remainder is f(−b/a).

Here, dividing by (3x + 2) means we substitute x = −2/3 into f(x).

f(−2/3) = 15(−8/27) − 14(4/9) − 4(−2/3) + 10

f(−2/3) = −40/9 − 56/9 + 24/9 + 90/9 = 18/9 = 2

∴ The correct answer is 2.

Alternate Method

Given:

Polynomial f(x) = 15x³ − 14x² − 4x + 10

Divisor = 3x + 2

Remainder Theorem: If f(x) is divided by ax + b, the remainder is f(−b/a).

Calculations:

⇒ Let 3x + 2 = 0

⇒ 3x = −2

⇒ x = −2/3

⇒ Substitute x = −2/3 in f(x) to find the remainder:

⇒ Remainder = 15(−2/3)³ − 14(−2/3)² − 4(−2/3) + 10

⇒ Remainder = 15(−8/27) − 14(4/9) + 8/3 + 10

⇒ Remainder = −40/9 − 56/9 + 24/9 + 90/9

⇒ Remainder = (−40 − 56 + 24 + 90) / 9

⇒ Remainder = 18 / 9

⇒ Remainder = 2

∴ The correct answer is 2.

Additional Information

Remainder Theorem

When a polynomial p(x) is divided by a linear polynomial (x − a), the remainder is equal to p(a).

Factor Theorem

A polynomial p(x) has a factor (x − a) if and only if p(a) = 0. This is a special case of the remainder theorem.

Given:

The average present age of four members of a family is 27 years 

Average increases by 3 years when one of their relatives joins them

Concept used:

Average value = (Sum of all the values)/Total no. values)

Calculations:

Let the age of relative be 'x'

According to the question,

Average age = [(4 × 27) + x]/5

⇒ 30 = (108 + x)/5

⇒ 108 + x = 150

⇒ x = 150 - 108 = 42 years

∴ The age of the relative is 42 years. 

Shortcut Trick

Average increases by 3 years when one of their relatives

joins them and common average = 27

Total member = 5 

so, extra age = 5 × 3 = 15

new relative age = 27 +15 = 42

Given:

Percentage = (Given value/Total value) × 100

Calculations:

According to the question,

Total percentage (P_T) student acquired = 90% of internal test + 95% of Assignments + 75% of external exam

⇒ PT = 90% of 30 + 95% of 30 + 75% of 40

⇒ PT = 90% × 30 + 95% × 30 + 75% × 40

⇒ PT = 0.90 × 30 + 0.95 × 30 + 0.75 × 40

⇒ PT = 27% + 28.5% + 30%

⇒ PT = 85.50%

Given:

Total spending of the country = ₹15,62,000

Concept used:

Percentage = (Given value/Total value) × 100

Calculations:

According to the question,

Money spent on District C = 14% of total money

⇒ District C = 14% of 1562000

⇒ District C = 14/100 × 1562000

⇒ District C = 14 × 15620 = Rs. 218680

Money spent on District C = 18% of total money

⇒ District E = 18% of 1562000

⇒ District E = 18/100 × 1562000

⇒ District E = 18 × 15620 = Rs. 281160

Now difference between money spent of district C and district E

⇒ (Money spent on District E) - (Money spent on District C)

⇒ (281160) - (218680) = Rs. 62480

∴ Rs. 62480 is spent on District C than on District E.

∴ 9832 - 172 is 966000.

Shortcut Trick

The remaining work can be completed by 30 men in (24 − 12) = 12 days.

After 10 more men join, total men working = 30 + 10 = 40.

Applying the M₁ × D₁ = M₂ × D₂ rule for the remaining work:

30 × 12 = 40 × D₂

D₂ = 360 ÷ 40 = 9 days.

∴ The correct answer is 9 days.

Alternate Method

Given:

Initial number of men = 30

Total time to complete the work = 24 days

Number of days worked initially = 12 days

Number of new men joined = 10

Calculations:

⇒ Let the efficiency of 1 man be 1 unit/day.

⇒ Total work = 30 × 24 = 720 units.

⇒ Work done in 12 days by 30 men = 30 × 12 = 360 units.

⇒ Remaining work = 720 − 360 = 360 units.

⇒ Total men working after 12 days = 30 + 10 = 40 men.

⇒ Total efficiency of 40 men = 40 units/day.

⇒ Time required for remaining work = Remaining work ÷ Total efficiency

⇒ Time required = 360 ÷ 40 = 9 days.

∴ The correct answer is 9 days.

Additional Information

Chain Rule (MDH Concept)

Used to relate Men (M), Days (D), Hours (H) and Work (W) across two scenarios: (M₁ × D₁ × H₁) ÷ W₁ = (M₂ × D₂ × H₂) ÷ W₂.

Efficiency Concept

Efficiency is inversely proportional to the time taken. If A is twice as efficient as B, then A takes half the time B takes to finish the same piece of work.

Work and Wages

Wages are always distributed in direct proportion to the total work done by each person, or in the ratio of their efficiencies if they work for the exact same number of days.

Given:

Marked Price = Rs. 8000

First Discount = 35%

Successive discounts on the bill = 20% and 15%

Formula used:

S.P = [(100- Discount% ) /100] × M.P

In case of successive discounts, equivalent discount% = a + b - (ab/100)

Where, a = First discount percentage, b = Second discount percentage

Calculation:

According to the first condition,

⇒ S.P₁ = [(100 - 35)/100] × 8000

⇒ S.P₁ = 65/100 × 8000

⇒ S.P1 = 0.65 × 8000 = Rs. 5200

According to the second condition, 

Equivalent discount = 20 + 15 - (20 × 15/100)

Equivalent discount = (35 - 3)%

Equivalent discount = 32%

⇒ S.P₂ = [(100 - 32)/100] × 8000

⇒ S.P2 = [68/100] × 8000

⇒ S.P2 = 0.68 × 8000 = Rs. 5440

Now the difference between the First condition and second condition = Rs. 5440 - Rs. 5200 = Rs. 240

∴ The difference between the First and second discounts is Rs. 240.   

Shortcut Trick

Condition (2) 

 

⇒ MRP =5 × 20 =100(unit)  SP = 4 × 17 = 68(unit)

⇒ 100 (unit) = 8000 so 68(unit) = 5440...(2)

Difference = 5440 - 5200 = 240

Calculations:

The largest 6-digit number = 999999

Dividing 999999 by 52 gives the quotient as 19230 and 39 as the remainder,

Now the largest 6-digit number divisible by 52

⇒ 999999 = 19230 × 52 + 39 (remainder 39)

⇒ 999999 - 39 = 999960

∴ The largest 6-digit number divisible by 52 is 999960.

Formula Used:

Average Speed = Total Distance / Total Time

Time = Distance / Speed

100 km 30 km/h 100 km 40 km/h 100 km 50 km/h Total Distance = 300 km

Calculations:

⇒ Total Distance = 100 + 100 + 100 = 300 km

⇒ Time for 1^st part (t₁) = 100 / 30 = 10/3 hours

⇒ Time for 2^nd part (t₂) = 100 / 40 = 2.5 hours

⇒ Time for 3^rd part (t₃) = 100 / 50 = 2 hours

⇒ Total Time = 10/3 + 2.5 + 2 = 10/3 + 4.5

⇒ Total Time = 10/3 + 9/2 = (20 + 27) / 6 = 47 / 6 hours

⇒ Average Speed = 300 / (47 / 6) = (300 × 6) / 47

⇒ Average Speed = 1800 / 47 ≈ 38.297 km/h

⇒ Average Speed ≈ 38.3 km/h

∴ The correct option is B.

Additional Information

Average Speed for Two Equal Distances

If a journey is divided into two equal distances with speeds x and y, Average Speed = 2xy / (x + y).

Harmonic Mean Property
