SSC CGL Undated PYQs

Question 1

What is the percentage increase in education loan disbursed by Bank 2 from 2010 to 2014?

Accepted Answer

Use the percentage increase formula: [(Value in 2014 - Value in 2010) / Value in 2010] × 100. Substituting the data table values gives exactly 87.69%.

Question 2

In the following question, select the related word from the given alternatives. Calendar : Date : : Index : ?

Accepted Answer

A calendar is used to look up a specific date. Similarly, an index in a book is used to look up specific contents or topics.

Question 3

Accepted Answer

A prime number is only divisible by 1 and itself. Option 3 contains 43, 1, 23, 95, 89. However, 1 is not a prime number. The question is flawed. Assuming it means numbers that are not composite, 1 is included. 95 is not prime (5x19). The question is flawed, but option 3 is the intended answer.

Question 4

Ratio of present ages of P and Q is 9 : 4. The difference between their ages is 20 years. What will be the sum (in years) of their ages after 10 years?

Accepted Answer

Let ages be 9x and 4x. Difference is 5x = 20, so x = 4. Present sum = 13x = 52. After 10 years, sum = 52 + 10 + 10 = 72.

Question 5

Sec 45% + Tan 30% = Sec 45% + Tan 30% =

Accepted Answer

The question contains typographical errors. Assuming it meant sec 45° + tan 30°, the values are √2 and 1/√3, giving (√6 + 1)/√3.

Question 6

In the question a statement is given, followed by two arguments, I and II. You have to consider the statement to be true even if it seems to be at variance from commonly known facts. You have to decide which of the given arguments, if any, is a strong argument. Statement : Should sale of alcohol near highways be banned? Argument I : No, people should have freedom to decide as it is their fundamental right. Argument II : Yes, 90% of road accidents involve drivers who are under influence of alcohol.

Accepted Answer

Argument I is strong as it highlights constitutional fundamental rights and personal freedom. Argument II is also strong because it provides a crucial safety perspective backed by data. Hence, both are strong.

Question 7

What is the LCM of 64 and 56?

Accepted Answer

Prime factorization of 64 is 2^6 and 56 is 2^3 × 7. The LCM takes the highest powers of all prime factors: 2^6 × 7 = 64 × 7 = 448.

Question 8

What is the simple annual growth rate (in %) in the sales of SUV from 2009 to 2012?

Accepted Answer

Find the total percentage increase from 2009 to 2012 using the given data, then divide by the number of years (3 years) to get the simple annual growth rate of 133.33%.

Question 9

In which market form, a market or industry is dominated by a few ﬁrms?

Accepted Answer

An oligopoly is a market structure where a small number of large firms dominate the industry, often leading to limited competition and interdependent decision-making among them.

Question 10

If length of each side of a rhombus PQRS is 8 cm and ∠PQR = 120°, then what is the length (in cm) of QS?

Accepted Answer

In rhombus PQRS, adjacent angles are supplementary, so ∠SPQ = 60°. Since sides PQ = PS = 8 cm, triangle PQS is equilateral. Thus, diagonal QS is also 8 cm.

Question 11

A batsman makes a score of 95 runs in the 13th match and thus increases his average runs per match by 4. What is his average after the 13th match?

Accepted Answer

Let the old average be x. Total runs = 12x. New total = 12x + 95 = 13(x + 4). Solving gives x = 43. New average = 43 + 4 = 47.

Question 12

In the following question, select the missing number from the given series. 19, 38, ?, 228, 684, 1368 19, 38, ?, 228, 684, 1368

Accepted Answer

The pattern alternates between multiplying by 2 and 3. 19×2=38, 38×3=114, 114×2=228, 228×3=684. Thus, the missing number is 114.

Question 13

If HEROISM is coded as SVILRHN, then how will ALP be coded as?

Accepted Answer

Each letter is replaced by its opposite letter in the English alphabet (A↔Z, B↔Y, etc.). Thus, A becomes Z, L becomes O, and P becomes K, giving ZOK.

Question 14

Which of the following is a characteristic of an exothermic reaction?

Accepted Answer

An exothermic reaction is a chemical reaction that releases energy, usually in the form of heat or light, into its surroundings, causing the temperature to rise.

Question 15

Two women A and B are shopping in a mall. They start from the same point. A walks 150 m West, then turns to her left and walks 160 m. B walks 140 m East, then turns South and walks 160 m, then turns to her left and walks 120 m. Where is B with respect to A now?

Accepted Answer

A reaches 150m West and 160m South. B reaches (140+120)=260m East and 160m South. Both are on the same horizontal line. Distance = 150 + 260 = 410m. B is East of A.

Question 16

Sum of four times a fraction and 7 times its reciprocal is 16. What is the fraction?

Accepted Answer

Let the fraction be x. The equation is 4x + 7/x = 16. Checking option 2: 4(7/2) + 7(2/7) = 14 + 2 = 16. Thus, 7/2 is correct.

Question 17

What is plant cell wall mainly composed of?

Accepted Answer

Plant cell walls are primarily made of cellulose, a complex carbohydrate that provides structural support and rigidity to the plant cells.

Question 18

10 women can do a piece of work in 6 days, 6 men can do same work in 5 days and 8 children can do it in 10 days. What is the ratio of the efﬁciency of a woman, a man and a child respectively?

Accepted Answer

Total work = 10W × 6 = 6M × 5 = 8C × 10. This gives 60W = 30M = 80C, or 6W = 3M = 8C. The efficiency ratio W:M:C is 1/6 : 1/3 : 1/8 = 4 : 8 : 3.

Question 19

If Sin θ = 12/13, then what is the value of Cot θ?

Accepted Answer

Sin θ = Perpendicular/Hypotenuse = 12/13. By Pythagoras theorem, Base = √(13² - 12²) = 5. Cot θ = Base/Perpendicular = 5/12.

Question 20

With which country India has recently signed a MoU for Water Conservation in India?

Accepted Answer

India signed an MoU with Israel to enhance cooperation in water conservation and state water utility management, leveraging Israel's advanced water technologies and expertise.
