SSC CGL Undated PYQs

Question 1

____________ scheme by the Central Government aims at setting up an organized rural Panchayat in order to make the villages more self-sustained.

Accepted Answer

'Gram Uday Se Bharat Uday Abhiyan' was launched to strengthen Panchayati Raj institutions and promote rural development, aiming to make villages self-sustained and prosperous.

Question 2

If (x – 2)2 + (y + 3)2 + (z – 15)2 = 0, then what is the value of x + y + z – 5?

Accepted Answer

Since the sum of squares is zero, each term must be zero. Thus, x = 2, y = -3, and z = 15. Substituting these gives 2 - 3 + 15 - 5 = 9.

Question 3

A spaceship travels at 810 km/hr. How many metres does it travel in 1/5th of a second?

Accepted Answer

Convert speed to m/s by multiplying 810 by 5/18 to get 225 m/s. Multiply this by the time (1/5 s) to find the distance: 225 × 1/5 = 45 metres.

Question 4

A woman walks 3 km North, then turns West and walks 4 km, then turns South and walks 7 km, then turns to her left and walks 4 km. Where is she now with reference to her starting position?

Accepted Answer

She goes 3 km North, 4 km West, 7 km South, and 4 km East (left turn from South). East-West cancels out. Net vertical movement is 3 - 7 = -4 km, meaning 4 km South.

Question 5

Bhavin's birthday is on Monday 29th May. On what day of the week will be Rachit's Birthday in the same year if Rachit was born on 17th November?

Accepted Answer

Total days from May 29 to Nov 17: May(2) + Jun(30) + Jul(31) + Aug(31) + Sep(30) + Oct(31) + Nov(17) = 172 days. 172 ÷ 7 leaves remainder 4. Monday + 4 = Friday.

Question 6

Who invented the Centigrade scale?

Accepted Answer

Swedish astronomer Anders Celsius invented the Centigrade (Celsius) temperature scale in 1742, basing it on the freezing and boiling points of water.

Question 7

Two trains are moving in the opposite directions at speed of 43 km/h and 51 km/h respectively. The time taken by the slower train to cross a man sitting in the faster train is 9 seconds. What is the length (in metres) of the slower train?

Accepted Answer

Relative speed in opposite directions = 43 + 51 = 94 km/h. Convert to m/s: 94 × 5/18. Length of slower train = Relative speed × time = (94 × 5/18) × 9 = 235 m.

Question 8

ABCD is a parallelogram in which AB = 7 cm, BC = 9 cm and AC = 8 cm. What is the length (in cm) of other diagonal?

Accepted Answer

Use the parallelogram law: 2(AB² + BC²) = AC² + BD². Substituting the values gives 2(49 + 81) = 64 + BD², so BD² = 196, making BD = 14 cm.

Question 9

_____________ is the number of deaths in the population during a given period.

Accepted Answer

Mortality refers to the number of deaths in a population over a specific period. In contrast, natality refers to the number of births.

Question 10

Area of 4 walls of a cuboid is 448 sq cm, its length is 18 cm and height is 8 cm. What is its breadth (in cm)?

Accepted Answer

The area of 4 walls of a cuboid is 2(l + b)h. Given 2(18 + b) × 8 = 448. Solving this: 16(18 + b) = 448, so 18 + b = 28, which gives b = 10 cm.

Question 11

The average weight of P, Q and R is 45 kg. If the average weight of P and Q be 36.5 kg and that of Q and R be 52 kg, then what is the weight (in kgs) of Q?

Accepted Answer

Total weight of P+Q+R = 45 × 3 = 135 kg. P+Q = 36.5 × 2 = 73 kg. Q+R = 52 × 2 = 104 kg. Q = (P+Q) + (Q+R) - (P+Q+R) = 73 + 104 - 135 = 42 kg.

Question 12

Slope of the line AB is -4/3. Co-ordinates of points A and B are (x, -5) and (-5, 3) respectively. What is the value of x?

Accepted Answer

Use the slope formula m = (y2 - y1) / (x2 - x1). Here, -4/3 = (3 - (-5)) / (-5 - x). Solving gives -4/3 = 8 / (-5 - x), so 20 + 4x = 24, meaning x = 1.

Question 13

Area of 4 walls of a cuboid 400 sq cm, its length is 15 cm and height is 8 cm. What is its breadth (in cm)?

Accepted Answer

Area of 4 walls = 2(l + b)h. Given 2(15 + b) × 8 = 400. So, 16(15 + b) = 400, which gives 15 + b = 25. Thus, b = 10 cm.

Question 14

If Cosec θ = 25/7 , then what is the value of Cot θ?

Accepted Answer

Cosec θ = Hypotenuse/Opposite = 25/7. Using the Pythagorean triplet (7, 24, 25), the adjacent side is 24. Therefore, Cot θ = Adjacent/Opposite = 24/7.

Question 15

'Neo-Malthusian Theory' is associated with which of the following?

Accepted Answer

Neo-Malthusian theory argues that rapid population growth will outpace agricultural production and available resources, ultimately leading to severe resource scarcity and environmental degradation.

Question 16

Which key is used to move to next line in a Ms-Word document?

Accepted Answer

In MS Word, pressing the Enter key inserts a paragraph break, moving the cursor to the beginning of the next line.

Question 17

In the following question, select the related word from the given alternatives. Mathematics : Formulas : : Chemistry : ?

Accepted Answer

Just as mathematics is fundamentally based on formulas to solve problems, chemistry relies heavily on chemical reactions to understand and describe processes.

Question 18

Which among the following is used to treat Indigestion?

Accepted Answer

Antacids are mild bases, such as magnesium hydroxide, that neutralize excess stomach acid. This neutralization process provides quick relief from indigestion and heartburn.

Question 19

A] The author of the novel 'The Corrections' is Jonathan Franzen. B] The author of the novel 'A Visit from the Goon Squad' is Edward P Jones. C] The author of the novel 'Forty Thieves' is Thomas Perry. Which of the statements given above are correct?

Accepted Answer

Statements A and C are correct. Statement B is incorrect because the novel 'A Visit from the Goon Squad' was actually written by Jennifer Egan, not Edward P Jones.

Question 20

In the following question, select the odd word pair from the given alternatives.

Accepted Answer

Dates are recorded in a calendar, notes in a notebook, and entries in accounts. All are written records. Milk is a physical product obtained from a dairy, making it the odd one out.
