SSC CGL Undated PYQs

Question 1

______________ 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 2

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 3

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 4

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 5

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 6

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 7

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 8

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 9

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 10

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 11

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 12

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 13

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 14

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 15

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.

Question 16

A wholesaler sells a jacket to a retailer at a proﬁt of 5% and the retailer sells it to a customer at a proﬁt of 10%. If the customer pays Rs. 4158, what had it cost (in Rs) to the wholesaler?

Accepted Answer

Let the wholesaler's cost be x. Successive profits mean x × 1.05 × 1.10 = 4158. Solving this gives x × 1.155 = 4158, so x = 3600.

Question 17

The flight fare between two cities is increased in the ratio 9:11. What is the increase (in Rs) in the fare, if the original fare was Rs. 18,000?

Accepted Answer

The original fare corresponds to 9 parts, so 1 part = 18000 / 9 = 2000. The increase is 11 - 9 = 2 parts. Thus, the increase is 2 × 2000 = Rs. 4000.

Question 18

A bag has Rs 43 in the form of 5-rupee, 50-paise and 10-paise coins in the ratio of 1:5:11. What is the total number of 50-paise coins?

Accepted Answer

Let the coins be x, 5x, and 11x. Total value in rupees: 5x + 0.5(5x) + 0.1(11x) = 43. So, 8.6x = 43, giving x = 5. Number of 50-paise coins = 5x = 25.

Question 19

Select the related number from the given alternatives. 64 : 8 :: 0.01 : ?

Accepted Answer

The relationship is based on the square root of the first number. Since √64 = 8, applying the same logic, the square root of 0.01 is 0.1.

Question 20

Sandy and Mandy do (8/13)th part of a work and the rest of the work was completed by Andy. If Sandy, Mandy and Andy take the same work for Rs 2600, then what is the share (in Rs) of Andy?

Accepted Answer

Andy's share of the work is 1 - 8/13 = 5/13. Since wages are distributed in proportion to the work done, Andy's share is (5/13) × 2600 = Rs 1000.
