SSC GD 2021 PYQs

Question 1

From the given alternatives select the number that can replace the question mark (?) in the given series.15,16, 20, 47, 303, ?

Accepted Answer

The pattern is: 15 + 1^3 = 16, 16 + 2^3 = 24 (error in question, should be 20), 20 + 3^3 = 47, 47 + 4^3 = 303. So, 303 + 5^3 = 303 + 125 = 428. Wait, the question has a typo. Let's re-evaluate. The pattern is: 15 + 1^1 = 16, 16 + 2^2 = 20, 20 + 3^3 = 47, 47 + 4^4 = 303. So, 303 + 5^5 = 303 + 3125 = 3428.

Question 2

Six friends A, B, C, D, E and F, have different heights. A is taller than only C and E. B is shorter than D but D is not the tallest among them. Who is the tallest among them all?

Accepted Answer

A is taller than only C and E, so C, E < A. D is not the tallest. B < D. This implies F must be the tallest, as all others are placed.

Question 3

In a certain code language, ‘GREW’ is coded as ‘209224’.How will ‘TYPE’ be coded in that language?

Accepted Answer

The code uses the reverse alphabetical position of each letter. G is 20th from Z, R is 9th, E is 22nd, W is 4th. Applying this, T=7, Y=2, P=11, E=22. So, TYPE is 721122.

Question 4

Five friends, Bhumika, Rashi, Shweta, Vibha and Arunima, are sitting in a row facing east. Bhumika is sitting between Vibha and Shweta. Rashi is second to the left of Shweta. Who is sitting at the south end?

Accepted Answer

Facing east, 'left' is north and 'right' is south. 'Rashi is second to the left of Shweta' means the order is Rashi, _, Shweta. 'Bhumika is between Vibha and Shweta' means the order is Vibha, Bhumika, Shweta. Combining these, the full arrangement from north to south is: Arunima, Rashi, Vibha, Bhumika, Shweta. Therefore, Vibha is at the south end.

Question 5

Study the given pattern carefully and select the number that can replace the question mark (?) in it.162951991441726?16

Accepted Answer

By analyzing the rows or columns, a specific mathematical operation (like multiplication followed by subtraction) is applied to the first two numbers to get the third. Applying this to the last row gives 407.

Question 6

In a certain code language, 'ORACLE' is written as 'HSVUXG' and 'DAVID' is written as 'BVJFB'. How will 'VIDEO' be written in that language?

Accepted Answer

The logic is different for vowels and consonants. Consonants are coded to the next letter (+1). Vowels have a fixed code: A→V, E→G, I→F, O→H, U→J. For VIDEO: V(consonant)→W, I(vowel)→F, D(consonant)→E, E(vowel)→G, O(vowel)→H. Thus, VIDEO becomes WFEGH.

Question 7

In a certain code language, ‘DESK’ is coded as ‘@#+%’ and ‘RAIN’ is coded as ‘$-×*’. How will ‘RISK’ be coded in that language?

Accepted Answer

Identify the direct mapping for each letter from the given codes. R is $, I is ×, S is +, K is %. Combine these to get the code for RISK.

Question 8

Four letter - clusters have been given, out of which three are alike in some manner and one is different. Select the letter - cluster that is different.

Accepted Answer

In options 2, 3, and 4, the letters follow a pattern of -3, -2, -1. For example, G(-3)D(-2)B(-1)A. Option 1 (YUSR) follows -4, -2, -1, making it the odd one out.

Question 9

L is the mother of M. L has only two children. N is the sister of M. N is the daughter of K. Z is the grandson of K. O is the mother of Z. How is O related to N?

Accepted Answer

L and K are parents of M and N. Z is K's grandson, so Z is M's or N's child. Since O is Z's mother, O must be M's wife, making her N's sister-in-law.

Question 10

In a certain code language, 'MANGO' is written as 'QERKS' and 'APPLE' is written as 'ETTPI'. How will 'GUAVA' be written in that language?

Accepted Answer

The pattern is +4, +3, +2, +1, +0 for each letter. Applying this to GUAVA: G+4=K, U+3=X, A+2=C, V+1=W, A+0=A. So, GUAVA becomes KXCW A. Wait, the correct answer is KYEZE. Let's re-evaluate the pattern. M(13)+4=Q(17), A(1)+4=E(5), N(14)+4=R(18), G(7)+4=K(11), O(15)+4=S(19). So, it's a consistent +4 shift for MANGO. For APPLE: A(1)+4=E(5), P(16)+4=T(20), P(16)+4=T(20), L(12)+4=P(16), E(5)+4=I(9). It's also a consistent +4 shift. Therefore, for GUAVA: G+4=K, U+4=Y, A+4=E, V+4=Z, A+4=E. The answer is KYEZE.

Question 11

'Printer' is related to 'Hardware' in the same way as 'Web Browser' is related to '________'.

Accepted Answer

A printer is a type of hardware. Similarly, a web browser is a type of software. This establishes a 'type of' relationship.

Question 12

Select the dice that can be performed by folding the given sheet along the lines.

Accepted Answer

In the given sheet, the opposite faces are (F, B), (E, C), and (A, D). Opposite faces cannot be adjacent. Dice B and D show opposite faces (F,B) and (A,D) together, so they are impossible. Dice A and C are possible.

Question 13

‘Cricket’ is related to ‘LBW’ in the same way as ‘Chess’ is related to ‘______’.

Accepted Answer

LBW is a specific term used in Cricket. Similarly, 'Checkmate' is a specific term used to denote the end of a game in Chess.

Question 14

Three different positions of the same dice are shown. Select the number that will be on the face opposite to the one having '4'.

Accepted Answer

From the first two dice, 1 and 5 are common. So, 4 is opposite to 2. Alternatively, compare dice 2 and 3, 3 and 5 are common, so 4 is opposite to 2.

Question 15

'P × Q' means 'P is the wife of Q'. 'P + Q' means 'P is the father of Q'. 'P ÷ Q' means 'P is the daughter of Q'. 'P - Q' means 'P is the son of Q'. How is E related to I in the expression 'E ÷ F + G - H ÷ I' ?

Accepted Answer

Break down the expression: E is F's daughter. F is G's father. G is H's son. H is I's daughter. This means E is G's daughter, and G is I's grandchild, making E I's great-grandchild. Wait, re-evaluating: E is F's daughter. F is G's father. So E is G's sister. G is H's son. H is I's daughter. So G is I's grandson. Since E is G's sister, E is I's granddaughter.

Question 16

'Dictionary' is related to 'Meaning' in the same way as 'Encyclopaedia' is related to '_________ '.

Accepted Answer

A dictionary provides meanings of words. Similarly, an encyclopedia provides comprehensive knowledge on various subjects. Thus, 'Knowledge' is the correct relation.

Question 17

Five persons are sitting in a row facing north. Driver and Electrician sit at both ends of the row. The plumber sits next to the right of the carpenter. The mechanic sits next to the immediate left of the electrician. The carpenter sits exactly between the driver and the plumber. Who among the following person sits in the middle of the row?

Accepted Answer

Arrange the persons based on given clues: Driver, Carpenter, Plumber, Mechanic, Electrician. The plumber is in the middle position.

Question 18

Whichtwo numbers (NOT digits)need to be interchanged to make the following equation correct?3 × 45 ÷ 5 + 7-12 = 70

Accepted Answer

Interchanging 3 and 5 gives 5 × 45 ÷ 3 + 7 - 12. Following BODMAS: 5 × 15 + 7 - 12 = 75 + 7 - 12 = 82 - 12 = 70. Thus, option 1 is correct.

Question 19

Five friends, P, Q, R, S and T are sitting in a row facing south. Q is sitting in the centre position. P is sitting at the west end. T and R are sitting on one side of Q. Two persons are sitting between P and R. Who is sitting between Q and P?

Accepted Answer

P is at the west end. Q is in the center. Two people are between P and R. This places R to the right of P. The arrangement is P _ _ R Q. The remaining person S fills the gap between P and Q.

Question 20

If the diagonal of a square is increased by 4 cm, its area increases by 56 cm2. Find the ratio of the new area of the square to the initial area of the square.

Accepted Answer

Let initial diagonal be d. Area = d^2/2. New diagonal = d+4. New Area = (d+4)^2/2. Given (d+4)^2/2 - d^2/2 = 56. Solving gives d=12. Initial Area = 12^2/2 = 72. New Area = (12+4)^2/2 = 128. Ratio = 128/72 = 16/9.
