SSC CGL Undated PYQs

Question 1

Select the related letters from the given alternatives. BEH : KNQ :: FIL : ?

Accepted Answer

Each letter in the first term is shifted forward by 9 positions to get the second term. F+9=O, I+9=R, L+9=U. So, FIL becomes ORU.

Question 2

The areas of two similar triangles ΔABC and ΔPQR are 36 sq cms and 9 sq cms respectively. If PQ = 4 cm then what is the length of AB (in cm)?

Accepted Answer

For similar triangles, the ratio of areas equals the square of the ratio of corresponding sides. Area(ABC)/Area(PQR) = (AB/PQ)². 36/9 = (AB/4)². 4 = AB²/16. AB² = 64, so AB = 8 cm.

Question 3

Which Fundamental Right in the Indian Constitution states that all persons shall be equally protected by the laws of the country?

Accepted Answer

Article 14 under the Right to Equality guarantees equality before the law and equal protection of the laws within the territory of India for all persons.

Question 4

______________ scheme launched by the Central Government aims at development of rural growth clusters which have latent potential for growth.

Accepted Answer

The Shyama Prasad Mukherji Rurban Mission (SPMRM) was launched in 2016 to develop 300 rural clusters with urban-like facilities, stimulating local economic development and reducing rural-urban migration.

Question 5

In the following question, select the related letters from the given alternatives. YONEX : DUUMG : : JASPO : ?

Accepted Answer

The pattern adds +5, +6, +7, +8, +9 to the letters of YONEX. Applying the same to JASPO gives J+5=O, A+6=G, S+7=Z, P+8=X, O+9=X, resulting in OGZXX.

Question 6

Which of the following is not among the 3 main classes of Algae?

Accepted Answer

Algae are mainly divided into Chlorophyceae (green), Rhodophyceae (red), and Phaeophyceae (brown). Gymnosperms are seed-producing vascular plants, not algae, making option 4 the correct answer.

Question 7

If Cot θ = 21/20, then what is the value of Sec θ?

Accepted Answer

Cot θ = Base/Perpendicular = 21/20. The hypotenuse is √(21² + 20²) = √841 = 29. Sec θ is Hypotenuse/Base, which equals 29/21.

Question 8

The 7th pay commission has retained the rate of annual increment of _____.

Accepted Answer

The 7th Central Pay Commission retained the annual increment rate at 3% for government employees, continuing the practice established by the 6th Pay Commission.

Question 9

What is the process of rust forming on iron called?

Accepted Answer

The chemical process where iron reacts with oxygen and moisture in the environment to form iron oxide is called rusting.

Question 10

What is the value of 125% of 25% of 80?

Accepted Answer

Convert percentages to fractions: 125% = 5/4 and 25% = 1/4. Multiply them with 80: (5/4) × (1/4) × 80 = (5/16) × 80 = 25.

Question 11

A certain sum of money triples itself in 5 years at simple interest. In how many years it will be ﬁve times?

Accepted Answer

Money triples means interest is 2P in 5 years. To become 5 times, interest needed is 4P. Since 2P takes 5 years, 4P will take exactly double the time, which is 10 years.

Question 12

If Cot θ = 21/20, then what is the value of Cosec θ?

Accepted Answer

Cot θ = Base/Perpendicular = 21/20. The hypotenuse is √(21² + 20²) = √841 = 29. Cosec θ = Hypotenuse/Perpendicular = 29/20.

Question 13

In the following question, select the related letters from the given alternatives. TRACK : MECTV : : POND : ?

Accepted Answer

Reverse the letters of the word and add 2 to the positional value of each letter. POND reversed is DNOP. Adding 2 to each gives FPQR.

Question 14

In the following question, select the related letters from the given alternatives. JPC : GMZ : : PUV : ?

Accepted Answer

Each letter in the first term is shifted backward by 3 positions to get the second term (J-3=G, P-3=M, C-3=Z). Applying -3 to PUV gives MRS.

Question 15

What is the value of Sin 30° + Cos 30°?

Accepted Answer

We know that Sin 30° = 1/2 and Cos 30° = √3/2. Adding these values gives (1 + √3)/2.

Question 16

What should be the least number of runs that Pujara must have scored in total (runs can only be integers)? )?

Accepted Answer

Based on the given options and the requirement for the least integer value, 25 is the smallest possible total runs Pujara could have scored.

Question 17

Which student scored the maximum marks in all the 4 subjects taken together?

Accepted Answer

To find the maximum marks, calculate the total sum of scores in all 4 subjects for each student. Student 3 has the highest aggregate score.

Question 18

If the expression px3 – 2x2 – qx + 18 is completely divisible by (x2 – 9), then what is the ratio between p and q respectively?

Accepted Answer

Since the expression is divisible by (x2 - 9), substitute x = 3. We get 27p - 18 - 3q + 18 = 0, which simplifies to 27p = 3q, giving p:q = 1:9.

Question 19

Which of the following transports water from the roots of the plant to its leaves?

Accepted Answer

Xylem is the specialized vascular tissue responsible for transporting water and dissolved minerals upward from the roots to the leaves. Phloem transports food.

Question 20

In due course of time the meander loop cuts off from the river and forms a cut-off lake, also called an _________ lake.

Accepted Answer

As a river meanders, the neck of the loop becomes narrower until the river cuts straight through it, leaving behind a U-shaped body of water known as an ox-bow lake.
