SSC CGL Undated PYQs

Question 1

Bhutan does not share its border with which Indian state?

Accepted Answer

Bhutan shares borders with four Indian states: Sikkim, West Bengal, Assam, and Arunachal Pradesh. It does not share a border with Meghalaya, which is located further south, bordering Bangladesh.

Question 2

20% of a = b, then b% of 20 is the same as _________ of a.

Accepted Answer

Given b = 20% of a = 0.2a. We need b% of 20, which is (b/100) × 20 = b/5. Substituting b, we get 0.2a / 5 = 0.04a, which is 4% of a.

Question 3

Which of the following metal (shown by its symbol) is generally used for making filaments of bulb?

Accepted Answer

Tungsten (symbol W) is used for bulb filaments because it has a very high melting point and high resistance, preventing it from melting when glowing hot.

Question 4

Which of the following device is best suited for measuring the temperature inside metallurgical furnaces?

Accepted Answer

A pyrometer is a remote-sensing thermometer used to measure extremely high temperatures, making it ideal for metallurgical furnaces where direct contact is impossible or dangerous.

Question 5

In a certain code language, "TROUPE" is written as "GILFKV" and "ERUPTION" is written as "VIFKGRLM". How is "GENIUS" written in that code language?

Accepted Answer

Each letter is replaced by its opposite letter in the English alphabet (e.g., T-G, R-I). Applying this to GENIUS: G->T, E->V, N->M, I->R, U->F, S->H, giving TVMRFH.

Question 6

Which of the statements given below are correct? 1. The author of the novel 'Missile Gap' is Charles Stross. 2. The author of the novel 'Bird Box' is Victor LaValle. 3. The author of the novel 'The City and the City' is China Mieville.

Accepted Answer

Statements 1 and 3 are correct. 'Missile Gap' is by Charles Stross and 'The City and the City' is by China Mieville. 'Bird Box' was actually written by Josh Malerman.

Question 7

The salt concentration (measured as salinity in parts per thousand), is _______ % in sea.

Accepted Answer

The average salinity of seawater is typically around 35 parts per thousand (ppt), meaning there are about 35 grams of dissolved salts in one kilogram of seawater.

Question 8

Select the related number from the given alternatives. -3/7 : 7/3 :: 9/2 : ? -3/7 : 7/3 :: 9/2 : ?

Accepted Answer

The second term is the negative reciprocal of the first term. Therefore, the negative reciprocal of 9/2 is -2/9.

Question 9

If (x – y) = 7, then what is the value of (x – 15)3 – (y – 8)3?

Accepted Answer

Let A = x - 15 and B = y - 8. Then A - B = x - y - 7. Substituting x - y = 7 gives 7 - 7 = 0. Since A = B, A³ - B³ = 0.

Question 10

Which of the following is also known as Carbolic Acid?

Accepted Answer

Phenol is an aromatic organic compound with the molecular formula C6H5OH. It was originally extracted from coal tar and is historically known as carbolic acid, widely used as an antiseptic.

Question 11

Hansh's birthday is on Monday 5th June. On what day of the week will be Tushar's Birthday in the same year if Tushar was born on 11th December?

Accepted Answer

Calculate days from June 5 to Dec 11: 25(Jun) + 31(Jul) + 31(Aug) + 30(Sep) + 31(Oct) + 30(Nov) + 11(Dec) = 189 days. 189 divided by 7 leaves 0 remainder, so it's Monday.

Question 12

Which of the following is a major river in Bangladesh which is also the main distributary of the Ganges?

Accepted Answer

When the Ganges river enters Bangladesh, its main distributary is known as the Padma. It later merges with the Jamuna (Brahmaputra) and Meghna rivers before emptying into the Bay of Bengal.

Question 13

Goods for which the quantity that a consumer chooses, increases as the consumer's income increases and decreases as the income decreases are called?

Accepted Answer

Normal goods have a positive income elasticity of demand. As consumers earn more, they buy more of these goods, unlike inferior goods where demand drops as income rises.

Question 14

Select the related word from the given alternatives. Plane : Pilot :: Ship : ?

Accepted Answer

Just as a pilot is the person who operates and commands a plane, a captain is the person in charge of commanding and steering a ship.

Question 15

A passage is given with 5 questions following it. Read the passage carefully and choose the best answer to each question out of the four alternatives. Many plays and films have depicted the life story of Gautama Buddha, but what made the musical play The Way Across unique was its regional focus. Directed by G. Kumara Swamy, the play adapted from the book Telangana lo Buddhism focused on the enlightenment of a cursed Brahmin Bawari and his 16 curious disciples willing to understand the deeper truths of birth, death, rebirth and brotherhood. From the impressive use of projector visuals, music and shadow-play, there was every effort to lend authenticity to the theme. Despite the play's focus on Telangana, the native essence was compromised, due to the English rendition (done for a wider reach). The lines appeared jaded with literal translations. The honest performances from the crew impacted only on a surface-level. Kiran Kumar's Bawari act and Krishna Chaitanya Joshi as Pingiya (said to have propagated Buddhism from Telangana to several regions across South India) grab your attention. What was sacrificed to keep the play in English?

Accepted Answer

The passage explicitly states, "Despite the play's focus on Telangana, the native essence was compromised, due to the English rendition." This directly answers what was sacrificed.

Question 16

______________ scheme by the Central Government aims at providing affordable aviation by making domestic flight charges economically accessible for middle-class citizens of India. 9/7/2017 Staff Selection Commision

Accepted Answer

UDAN (Ude Desh ka Aam Naagrik) was launched in 2016 by the Ministry of Civil Aviation to enhance regional connectivity and make air travel affordable for common citizens.

Question 17

In the following question, select the related number from the given alternatives. 3 : 27 : : 4 : ? 3 : 27 : : 4 : ?

Accepted Answer

The pattern is the cube of the first number. Since 3 cubed is 27, the cube of 4 is 4 × 4 × 4 = 64.

Question 18

Select the related letters from the given alternatives. WUS : DFH :: MKI : ? WUS : DFH :: MKI : ?

Accepted Answer

Each letter in the first term is replaced by its opposite letter in the English alphabet (W-D, U-F, S-H). Similarly, the opposites for M, K, and I are N, P, and R respectively.

Question 19

D and E are points on side AB and AC of ΔABC. DE is parallel to BC. If AD:DB = 2:3, what is the ratio of area of ΔADE and area of quadrilateral BDEC?

Accepted Answer

Since DE || BC, ΔADE ~ ΔABC. Ratio of sides AD:AB = 2:5. Ratio of areas = 4:25. Area of BDEC = 25 - 4 = 21. Required ratio is 4:21.

Question 20

What is the slope of the line perpendicular to the line passing through the points (-5 , 1) and (-2 , 0)?

Accepted Answer

First, find the slope of the given line: m = (0 - 1) / (-2 - (-5)) = -1/3. The perpendicular line's slope is the negative reciprocal, which is 3.
