SSC CHSL 2022 PYQs

Question 1

In a certain code language, 'COUNTY' is written as 'YTNUOC', and 'DEFEAT' is written as 'TAEFED'. How will 'FAMILY' be written in that language?

Accepted Answer

The pattern involves reversing the entire word. 'COUNTY' becomes 'YTNUOC' and 'DEFEAT' becomes 'TAEFED'. Applying this, 'FAMILY' becomes 'YLIMAF'.

Question 2

Which of the following numbers will replace the question mark (?) in the given series?1724, 1716, 1689, 1625, 1500, ?

Accepted Answer

The pattern is subtracting consecutive squares: 1724-8=1716 (2^3), 1716-27=1689 (3^3), 1689-64=1625 (4^3), 1625-125=1500 (5^3). So, 1500 - 6^3 (216) = 1284.

Question 3

If 20 July 2021 was Tuesday, then what was the day of the week on 28 November 2021?

Accepted Answer

Calculate odd days from July 20 to November 28. July (11), Aug (31), Sep (30), Oct (31), Nov (28). Total odd days: 11+31+30+31+28 = 131. Divide by 7: 131/7 = 18 remainder 5. Add 5 days to Tuesday to get Sunday.

Question 4

Which of the following numbers will replace the question mark (?) in the given series?2, 22, 32, 42, 57, 87,162, ?

Accepted Answer

The pattern is based on differences: 22-2=20, 32-22=10, 42-32=10, 57-42=15, 87-57=30, 162-87=75. The second differences are: -10, 0, 5, 15, 45. This is a geometric progression (x3, x3, x3...). The next second difference is 45x3=135. So, the next first difference is 75+135=210. Thus, 162+210=372. Wait, the correct answer is 387. Let's re-evaluate. The differences are: 20, 10, 10, 15, 30, 75. The pattern is: 20, 10 (20/2), 10 (10*1), 15 (10*1.5), 30 (15*2), 75 (30*2.5). The multiplier increases by 0.5 each time. So the next multiplier is 3. 75*3 = 225. Therefore, 162 + 225 = 387.

Question 5

In a certain code language, “AN” is coded as “16”, and “NO” is coded as “212”. How will “US” be coded in that language?

Accepted Answer

The pattern is (position of first letter + 1) * (position of second letter + 1). For AN: (1+1)*(14+1) = 2*15 = 30. This is not 16. Let's re-evaluate. The pattern is (position of first letter * position of second letter) - (position of first letter + position of second letter). For AN: (1*14) - (1+14) = 14 - 15 = -1. This is not 16. Let's try another pattern. The pattern is (position of first letter + 1) * (position of second letter + 1) - (position of first letter + position of second letter). For AN: (1+1)*(14+1) - (1+14) = 2*15 - 15 = 30 - 15 = 15. This is not 16. Let's try another pattern. The pattern is (position of first letter + 1) * (position of second letter + 1) - (position of first letter + position of second letter) + 1. For AN: (1+1)*(14+1) - (1+14) + 1 = 2*15 - 15 + 1 = 30 - 15 + 1 = 16. For NO: (14+1)*(15+1) - (14+15) + 1 = 15*16 - 29 + 1 = 240 - 29 + 1 = 212. For US: (21+1)*(19+1) - (21+19) + 1 = 22*20 - 40 + 1 = 440 - 40 + 1 = 401.

Question 6

Which letter-group will replace the question mark (?) in the given series?78, 97, 54, ?, 30, 145

Accepted Answer

The series alternates between adding 19 and subtracting 43. 78 + 19 = 97, 97 - 43 = 54. So, 54 + 19 = 73, and 73 - 43 = 30. The pattern is incorrect. The actual pattern is: 78 + 19 = 97, 97 - 43 = 54. Then 54 + 67 = 121, and 121 - 91 = 30. This is also incorrect. The correct pattern is: 78 + 19 = 97, 97 - 43 = 54. Then 54 + 67 = 121, and 121 - 91 = 30. This is also incorrect. The correct pattern is: 78 + 19 = 97, 97 - 43 = 54. The next step should be 54 + X = ?. The differences are +19, -43. The next difference should be +67. So 54 + 67 = 121. Then 121 - 91 = 30. The differences are 19, 43, 67, 91. The differences between these differences are 24. So the next difference is 91 + 24 = 115. So 30 + 115 = 145. Thus, the missing number is 121.

Question 7

In a certain code language, 'PENCIL' is written as '1771771418' and 'ERASER' is written as '6204231024'. How will 'SHARPNER' be written in that language?

Accepted Answer

The code uses (alphabet position + 1) for consonants and (alphabet position - 1) for vowels. Applying this rule to SHARPNER gives 201042221201226.

Question 8

If 13 January 2006 is a Friday, then what will be the day of the week on 28 March 2008?

Accepted Answer

From Jan 13, 2006 to Jan 13, 2008, there are 2 years. 2008 is a leap year, so 2 odd days for 2007 and 2 odd days for 2008 (Jan 13 to Mar 28). Total odd days = 2 + (18+29+28)/7 = 2 + 75/7 = 2 + 5 = 7. So, 0 odd days. Friday + 0 = Friday.

Question 9

Select the correct mirror image of the combination when the mirror is placed at MN as shown.

Accepted Answer

In a mirror image, the left and right sides are interchanged while the top and bottom remain the same. Apply this rule to each component of the given image.

Question 10

Select the Venn diagram that best illustrates the relationship between the following classes.King, Father, Queen

Accepted Answer

Some kings can be fathers, and some fathers can be kings. However, a queen is a distinct category, separate from both kings and fathers.

Question 11

Select the Venn diagram that best illustrates the relationship between the following classes.Fruit, Apple, Vegetable

Accepted Answer

Apples are a type of fruit, so the 'Apple' circle is entirely inside the 'Fruit' circle. Vegetables are distinct from fruits, so the 'Vegetable' circle is separate.

Question 12

In a certain code language, ‘RACE’ is written as ‘AREC’, and ‘PEAK’ is written as ‘EPKA’. How will ‘CORE’ be written in that language?

Accepted Answer

The pattern involves moving the first letter to the second position, the second to the first, and keeping the third and fourth letters in their original positions. Applying this to CORE gives OCER.

Question 13

In a certain code language, ‘ACNE’ is written as ‘XZVM’ and ‘BODY’ is written as ‘LYBW’. How will ‘EVIL’ be  written in that language?

Accepted Answer

The pattern is that each letter is replaced by its opposite letter in the alphabet (A=Z, B=Y, C=X, etc.). Applying this, E becomes V, V becomes E, I becomes R, and L becomes O. So, EVIL becomes VEOR.

Question 14

Which letter-cluster will replace the question mark (?) to complete the given series?HSDA, IZQT, ?, KNQF, LUDY

Accepted Answer

Analyze each letter's progression. First letter: H(+1)I(+1)J(+1)K(+1)L. Second letter: S(+7)Z(+7)G(+7)N(+7)U. Third letter: D(-10)T(-10)J(-10)Q(-10)D. Fourth letter: A(+12)Q(+12)M(+12)F(+12)Y. Thus, the missing cluster is JGDM.

Question 15

Pointing to a woman in the picture, Vishal said, "Her mother is the wife of my sister's father". How is the lady related to Vishal?something went wrong

Accepted Answer

Vishal's sister's father is Vishal's father. His father's wife is Vishal's mother. So, the woman's mother is Vishal's mother, making the woman Vishal's sister.

Question 16

Select the figure from among the given options that can replace the question mark (?) in the following series.

Accepted Answer

The pattern involves the inner figure rotating 90 degrees clockwise and the outer figure rotating 90 degrees anti-clockwise in each step. Following this, option 4 is correct.

Question 17

If ‘A’ denotes ‘+’, ‘B’ denotes ‘×’, ‘C’ denotes ‘–’ and ‘D’ denotes ‘÷’, then what will come in place of ‘?’ in the following equation?71 A 3 B 2 C 6 B (65 D 13) C 7 B 4 = ?

Accepted Answer

Substitute the symbols with operators: 71 + 3 × 2 - 6 × (65 ÷ 13) - 7 × 4. Follow BODMAS: first solve the bracket (65 ÷ 13 = 5), then multiplications, then additions and subtractions from left to right. This yields 71 + 6 - 30 - 28 = 77 - 58 = 19.

Question 18

Select the option figure which is embedded in the given figure as its part(rotation is NOT allowed).

Accepted Answer

Carefully observe the main figure. Option 2 perfectly fits within the main figure without any rotation, matching its exact shape and orientation.

Question 19

Which of the following numbers will replace the question mark (?) in the given series?67, 83, 71, 91, 80, 118, ?

Accepted Answer

The series has two alternating patterns. The first pattern is 67, 71, 80, ... (adding 4, then 9). The second pattern is 83, 91, 118, ... (adding 8, then 27). The next number in the first pattern should be 80 + 16 = 96.

Question 20

For what angle D is ΔABC congruent to ΔDEF, given AC = 2.5 cm, BC = 5 cm, ∠C = 75°, DE = 2.5 cm and DF = 5 cm?

Accepted Answer

For ΔABC to be congruent to ΔDEF by SAS criterion, AC must correspond to DE, BC to DF, and the included angle ∠C to ∠D. Thus, ∠D must be 75°.
