SSC GD 2019 PYQs

Question 1

In a certain code, BOTANY is written as OBATYN. How will OOLOGY be written in that code?

Accepted Answer

The pattern involves swapping letters in pairs: BO becomes OB, TA becomes AT, NY becomes YN. Applying this to OOLOGY, OO remains OO, LO becomes OL, GY becomes YG. Thus, OOLOGY becomes OOOLYG.

Question 2

In a certain code, SAW is written as 38. How will FEED be written in that code?

Accepted Answer

Assign numerical positions to letters (A=1, B=2...). SAW = S(19) + A(1) + W(23) = 43. Then, 43 - 5 = 38. Apply the same logic to FEED: F(6) + E(5) + E(5) + D(4) = 20. Then, 20 * 4 = 80. Wait, the pattern is (sum of positions) * number of letters. SAW: (19+1+23) = 43. Number of letters = 3. 43 * 3 = 129. This is not 38. Let's re-evaluate. SAW: S=19, A=1, W=23. Sum = 43. 43 - 5 = 38. This is not a consistent pattern. Let's try another pattern. SAW: S=19, A=1, W=23. Reverse positions: S=8, A=26, W=4. Sum = 38. This is the pattern! Now for FEED: F=21, E=22, E=22, D=23. Sum = 21+22+22+23 = 88.

Question 3

Find out the two signs to be interchanged to make the following equation correct.25 + 25 × 25 − 25 ÷ 25 = −599

Accepted Answer

Interchange '×' and '÷'. The equation becomes 25 + 25 ÷ 25 - 25 × 25. Applying BODMAS: 25 + 1 - 625 = 26 - 625 = -599. This matches the right side.

Question 4

If in a code language, MOTHER is coded as OMHTRE, then THURSDAY would be coded as:

Accepted Answer

The pattern involves swapping letters in pairs: M-O becomes O-M, T-H becomes H-T, E-R becomes R-E. Applying this to THURSDAY, T-H becomes H-T, U-R becomes R-U, S-D becomes D-S, A-Y becomes Y-A.

Question 5

Which of the two signs should be interchanged in order to make the following equation correct?21 + 5 × 2 – 21 ÷ 3 = 12

Accepted Answer

Interchange '-' and '×'. The equation becomes 21 + 5 - 2 × 21 ÷ 3. Following BODMAS: 21 + 5 - 2 × 7 = 21 + 5 - 14 = 26 - 14 = 12. This matches the RHS.

Question 6

Find out the two signs to be interchanged to make the following equation correct.30 + 28 × 3 – 16 ÷ 4 = - 50

Accepted Answer

Interchange '+' and '–'. The equation becomes 30 – 28 × 3 + 16 ÷ 4. Following BODMAS: 30 – 84 + 4 = -54 + 4 = -50. This matches the right side.

Question 7

Select the correct option that will fill the blank and complete the series.117, 107, 92, 72, .........

Accepted Answer

The pattern is a decreasing difference: 117-107=10, 107-92=15, 92-72=20. The next difference should be 25. So, 72-25=47.

Question 8

Select the word-pair that is analogous to the given word-pair.Bird : Fly

Accepted Answer

The analogy is 'Animal : Action'. A bird flies. Similarly, a horse gallops. This matches the relationship.

Question 9

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

Accepted Answer

The code is formed by taking the 2nd, 4th, 6th, and 8th letters of the original word and then repeating this sequence. For STEERING, the letters are T, E, I, G, which forms TEIG, repeated as TEIGTEIG. For QUESTION, the 2nd, 4th, 6th, and 8th letters are U, S, I, N. Repeating this gives USINUSIN.

Question 10

Select the option that will correctly replace the Q mark (?) in the series.109, 105, 89, 53, ?

Accepted Answer

The pattern is subtracting consecutive powers of 2. Differences are -4, -16, -36. These are -(2^2), -(4^2), -(6^2). The next difference will be -(8^2) = -64. So, 53 - 64 = -11.

Question 11

Select the option that will correctly replace the Question mark (?) in the series.13, 25, 42, 69, ?

Accepted Answer

The differences between consecutive terms are 12, 17, 27. The differences of these differences are 5, 10. The next difference should be 15, making the next term 69 + (27+15) = 111.

Question 12

If ‘+’ means ‘× ’, ‘-’ means ‘+’, ‘×’ means ‘÷ ’ and ‘÷’means ‘-‘, then find the value of the following equation:21 ÷ 8 + 2 − 12 × 3 =?

Accepted Answer

Replace symbols as given: 21 - 8 × 2 + 12 ÷ 3. Apply BODMAS: 21 - 16 + 4 = 5 + 4 = 9.

Question 13

Read the given statements and conclusion carefully and decide which of the following options is true with respect to the given conclusion.Statements:Men who are handsome are generally of the intellectual type.Vikram is handsome.Conclusion:Vikram is intellectual.

Accepted Answer

The statement says handsome men are 'generally' intellectual, not 'always'. Since Vikram is handsome, it's probable, but not certain, that he is intellectual.

Question 14

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

Accepted Answer

The pattern is that each letter is replaced by its opposite letter in the English alphabet (A-Z, B-Y, etc.). Apply this rule to QUESTION to get JFVHGRLM.

Question 15

In a certain code, JOY is written as 150. How will FEED be written in that code?

Accepted Answer

Assign numerical values to letters (J=10, O=15, Y=25). Sum them (10+15+25=50) and multiply by 3 (50*3=150). Apply the same logic to FEED: (F=6, E=5, E=5, D=4). Sum (6+5+5+4=20) and multiply by 4 (20*4=80).

Question 16

The numbers in the following set are related in a certain way. Choose the set that is similar to the following set:{4, 6, 9}

Accepted Answer

The given set {4, 6, 9} follows a pattern where the ratio of consecutive numbers is constant (6/4 = 1.5, 9/6 = 1.5). Option 3, {6, 12, 24}, also follows this pattern (12/6 = 2, 24/12 = 2).

Question 17

In a certain code, DIG is written as 60. How will FEED be written in that code?

Accepted Answer

Assign numerical positions to letters (A=1, B=2...). DIG = 4+9+7 = 20. Multiply by 3 (number of letters) to get 60. For FEED, 6+5+5+4 = 20. Multiply by 4 (number of letters) to get 80.

Question 18

In a certain code, COMPUTER is written as CEMOPRTU. How will CUPBOARD be written in that code?

Accepted Answer

The letters of the word COMPUTER are arranged alphabetically to form CEMOPRTU. Similarly, arrange the letters of CUPBOARD alphabetically to get ABCDOPRU.

Question 19

The statement below is followed by three conclusions labelled I, II and III. You have to assume everything in the statement to be true, and then decide which of the three suggested conclusions logically follows for pursuing.Statements:1) No school is an institution but they are establishment.2) All establishments that are not institutions have buildings.Conclusions:I. Schools are not establishments.II. All schools have buildings.III. Schools do not have buildings.

Accepted Answer

From statement 1, Schools are establishments. From statement 2, all establishments that are not institutions have buildings. Since schools are establishments and not institutions, all schools must have buildings. Thus, conclusion II follows.

Question 20

Select the correct option that will fill in the blank and complete the series.145, 100, 65, 40, ?

Accepted Answer

The differences between consecutive numbers are -45, -35, -25. This is an arithmetic progression with a common difference of 10. The next difference should be -15. So, 40 - 15 = 25.
