SSC GD 2019 PYQs

Question 1

Four numbers have been given out of which three are alike in some manner, while one is different. Choose the odd one.

Accepted Answer

All numbers except 33 are prime numbers. 33 is a composite number (3 x 11). Thus, 33 is the odd one out.

Question 2

Four options have been given out of which three are alike in some manner, while one is different. Choose the odd one.

Accepted Answer

All numbers except 3196 are divisible by 4. 2248/4 = 562, 3036/4 = 759, 1258/4 = 314.5 (incorrect, 1258 is not divisible by 4). Let's recheck. The pattern is that the first three numbers are divisible by 8. 2248/8 = 281, 3036/8 = 379.5 (incorrect). The pattern is that the sum of digits of the first three numbers is even. 2+2+4+8=16, 3+0+3+6=12, 1+2+5+8=16. For 3196, 3+1+9+6=19, which is odd. Thus, 3196 is the odd one out.

Question 3

Select the option that will correctly replace the q. mark (?) in theseries.RMB, POZ, NQX, LSV, ?

Accepted Answer

Analyze each letter's progression: R(-2)P(-2)N(-2)L(-2)J. M(+2)O(+2)Q(+2)S(+2)U. B(+4)Z(+4)X(+4)V(+4)T. Thus, the next term is JUT.

Question 4

Find the missing number from the below options.Figure

Accepted Answer

The pattern is that the number in the center is the HCF (Highest Common Factor) of the numbers in the corners of each triangle. For the first triangle, HCF(12, 18, 30) = 6. For the third triangle, HCF(16, 32, 40) = 8. Thus, for the second triangle, HCF(6, ?, 16) must be 2. The missing number is 4, as HCF(6, 4, 16) = 2.

Question 5

Eight friends A, B, C, D, E, F, G and H are sitting around circular table facing each other for a lunch. A is opposite F and third to the right of B. G is between F and D. H is to the left of D. E is between C and A. Who is sitting third to the right of H?

Accepted Answer

Place A opposite F. A is 3rd right of B, so B is 3rd left of A. G is between F and D. H is left of D. E is between C and A. This arrangement places F 3rd right of H.

Question 6

Select the option that will correctly replace the question mark (?) in the series.7, 19, 36, 63, ?

Accepted Answer

The differences between consecutive terms are 12, 17, 27. The second differences are 5, 10. The next second difference should be 15, making the next first difference 27+15=42. So, 63+42=105.

Question 7

Which two signs should be interchanged to make the following equation correct?12 + 18 × 24 ÷ 6 – 3 = 19

Accepted Answer

Interchanging ÷ and + gives 12 ÷ 18 × 24 + 6 – 3. Following BODMAS: 12/18 * 24 + 6 - 3 = 0.66 * 24 + 6 - 3 = 16 + 6 - 3 = 22 - 3 = 19. This matches the target.

Question 8

In a class of 45 students, a boy is ranked 20th. When two boys joined, his rank was dropped by one. What is his new rank from the end?

Accepted Answer

Initial rank is 20th. Two new students join, total students become 47. His rank drops by one, so new rank from top is 21st. Rank from end = (Total students - Rank from top) + 1 = (47 - 21) + 1 = 27th.

Question 9

Seven friends — Ajith, Bala, Hari, David, Raja, Sekar, and Guna — are sitting around a circular table. David is not the neighbor of Hari and Raja. Ajith is the neighbor of Bala and Hari. Guna, who is second to the left of David, is the neighbor of Sekar and Raja.What is the position of Hari?

Accepted Answer

Place Ajith between Bala and Hari. Guna is second left of David, and between Sekar and Raja. David is not next to Hari/Raja. This arrangement places Hari third to the left of Sekar.

Question 10

Select the option that will correctly replace the q. mark (?) in the series.8, 19, 41, 74, ?

Accepted Answer

The differences between consecutive terms are 11, 22, 33. This is an arithmetic progression with a common difference of 11. The next difference should be 44. So, 74 + 44 = 118.

Question 11

Seven friends O, P, Q, R, S, T and U are watching a movie sitting in a row. P is sitting at one extreme end. Q is sitting to the immediate left of S. P is sitting second to the right of T. U is not sitting at any extreme end. O is sitting between R and T. Who is sitting between P and T?

Accepted Answer

P is at an extreme end. P is second right of T, so T is not at an extreme end. This means P is at the rightmost end. The arrangement is T _ P. O is between R and T, so R O T _ P. Q is left of S. U is not at an extreme end. The final arrangement is R O T U Q S P. U is between P and T.

Question 12

In a certain code, ABOVE is written as ABEOV. How will QUESTION be written in that code?

Accepted Answer

The letters in ABOVE are rearranged alphabetically to form ABEOV. Applying the same logic, the letters in QUESTION when arranged alphabetically become EINOQSTU.

Question 13

Select the option that is related to the third term in the same way the second term is related to the first term.Television : Telecast :: Radio : ?

Accepted Answer

Television transmits content via 'Telecast'. Similarly, Radio transmits content via 'Broadcast'. This is a medium-to-transmission analogy.

Question 14

X, Y, Z, P, Q and R are sitting in a row facing north. X is the neighbour of Y and P. Q is the neighbour of Z and R, P is to the right of X and P and Z are immediate neighbours.Which pair sits on the extreme ends?

Accepted Answer

From the clues, deduce the arrangement: Y-X-P-Z-Q-R. Y is at the left end and R is at the right end. Thus, Y and R sit on the extreme ends.

Question 15

Select the number that DOES NOT belong to the following group.1, 2, 6, 21, 88, 446, 2676

Accepted Answer

The pattern is x1+1, x2+2, x3+3, x4+4, x5+5, x6+6. Following this, 88 * 5 + 5 = 445. So, 446 is the incorrect number.

Question 16

Select the option that will correctly replace the question mark (?) in the series.6, 21, 51, 96, ?

Accepted Answer

The differences between consecutive terms are 15, 30, 45. This is an arithmetic progression with a common difference of 15. The next difference will be 60. So, 96 + 60 = 156.

Question 17

Select the option that will correctly replace the question mark (?) in the series.100, 96, 80, 44, ?

Accepted Answer

The pattern is subtracting powers of 2: 100-4=96, 96-16=80, 80-36=44. The subtractions are 2^2, 4^2, 6^2. The next subtraction should be 8^2 = 64. So, 44 - 64 = -20.

Question 18

Find out the two signs to be interchanged to make the following equation correct.10 + 10 × 10 – 10 ÷ 10 = -89

Accepted Answer

Interchange '×' and '÷'. The equation becomes 10 + 10 ÷ 10 – 10 × 10. Applying BODMAS: 10 + 1 - 100 = 11 - 100 = -89. This matches the right-hand side.

Question 19

TIME is related to CLOCK in the same way as DISTANCE is related to:

Accepted Answer

A CLOCK measures TIME. Similarly, an ODOMETER is an instrument used to measure DISTANCE traveled by a vehicle.

Question 20

In which year was the constitution of Jammu and Kashmir adopted?

Accepted Answer

The Constitution of Jammu and Kashmir was adopted on November 17, 1956, and came into effect on January 26, 1957. This established its unique constitutional framework.
