SSC CGL Undated PYQs

Question 1

In Microsoft Word, _______ allows us to change the color of selected text.

Accepted Answer

In MS Word, the 'Font Color' tool located in the Home tab is specifically used to change the color of the selected text.

Question 2

If 3 # 4 % 8 = 6 and 9 % 4 # 3 = 12, then 12 % 6 # 24 = ?

Accepted Answer

Here, '#' represents division (/) and '%' represents multiplication (*). Applying this to 12 % 6 # 24 gives 12 * 6 / 24 = 72 / 24 = 3.

Question 3

Who discovered Electron?

Accepted Answer

J.J. Thomson discovered the electron in 1897 through his cathode ray tube experiments, proving that atoms contain negatively charged subatomic particles.

Question 4

Two cyclists P and Q cycle at 20 km/hr and 25 km/hr towards each other. What was the distance (in kms) between them when they started if they met after 56 minutes?

Accepted Answer

Since they move towards each other, relative speed is 20 + 25 = 45 km/hr. Time is 56/60 hours. Distance = Speed × Time = 45 × (56/60) = 42 km.

Question 5

If 19#13=3; 25#3=11; 36#10=13; then what is the value of 7#3=?

Accepted Answer

The pattern is (First Number - Second Number) / 2. For example, (19 - 13) / 2 = 3. Applying this to 7#3 gives (7 - 3) / 2 = 2.

Question 6

Point A (4 , 2) divides segment BC in the ratio 2:5. Co-ordinates of B are (2 , 6) and C are (7 , y). What is the value of y?

Accepted Answer

Using the section formula for the y-coordinate: y = (my₂ + ny₁)/(m+n). Substituting the values gives 2 = (2y + 5×6)/(2+5). Solving 14 = 2y + 30 yields y = -8.

Question 7

The short run marginal cost curve is ____ shaped.

Accepted Answer

The short-run marginal cost curve is U-shaped due to the law of variable proportions. It initially falls due to increasing returns, reaches a minimum, and then rises due to diminishing returns.

Question 8

The innermost layer is the core with a radius of about ___________ km.

Accepted Answer

The Earth's innermost layer, the core, consists of a solid inner core and a liquid outer core. Its total radius is approximately 3500 km, primarily composed of iron and nickel.

Question 9

Which of the following is an Inert Gas?

Accepted Answer

Argon is a noble gas found in Group 18 of the periodic table. It has a completely filled valence electron shell, making it chemically unreactive or inert.

Question 10

If 2/3(6x/5 - 1/4) + 1/3 = 9x/5, then what is the value of x?

Accepted Answer

Expand the bracket: 4x/5 - 1/6 + 1/3 = 9x/5. Simplify the constants to get 4x/5 + 1/6 = 9x/5. Subtract 4x/5 from both sides to find x = 1/6.

Question 11

What is the accepted average Calorie requirement for rural area in India?

Accepted Answer

In India, the accepted average calorie requirement is 2400 calories per person per day in rural areas and 2100 calories in urban areas, due to higher physical labor in villages.

Question 12

In computer terminology, what is the full form of FTP?

Accepted Answer

FTP stands for File Transfer Protocol. It is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network.

Question 13

If REGAINS is coded as QDFZHMR, then how will PRY be coded as?

Accepted Answer

Each letter in the word is shifted backward by one position in the alphabet (-1). Applying the same rule to PRY: P-1=O, R-1=Q, Y-1=X, giving OQX.

Question 14

CAD stands for _____.

Accepted Answer

CAD stands for Computer Aided Design. It refers to the use of computer software to create, modify, analyze, or optimize a design, widely used in engineering.

Question 15

In the following question, select the odd letter group from the given alternatives.

Accepted Answer

The pattern is adding 9 to the position of the first letter to get the second. A+9=J, E+9=N, N+9=W. But P+7=W, making PW the odd one.

Question 16

What is the average of all numbers between 9 and 90 which are divisible by 8?

Accepted Answer

The numbers divisible by 8 between 9 and 90 form an AP from 16 to 88. The average of an AP is (first + last)/2. So, (16 + 88)/2 = 52.

Question 17

If compound interest received on a certain amount in the 3rd year is Rs. 1,240, what will be the compound interest (in Rs) for the 4th year on the same amount at 9% rate of interest?

Accepted Answer

The compound interest for a specific year acts as the principal for the interest of the next year. Thus, CI for 4th year = 1240 × (1 + 9/100) = 1351.6.

Question 18

In the following question, select the missing number from the given series. 21, 25, 52, 68, 193, ?

Accepted Answer

The pattern of differences between consecutive terms is +2², +3³, +4², +5³. The next difference must be +6² = 36. So, 193 + 36 = 229.

Question 19

The ________ curve represents the demand of all consumers in the market taken together at different levels of the price of the good.

Accepted Answer

The market demand curve is the horizontal summation of individual demand curves, showing the total quantity demanded by all consumers in the market at various price levels.

Question 20

Improve the bracketed part of the sentence. We (has finished) our lunch half an hour ago.

Accepted Answer

The phrase 'half an hour ago' indicates a completed action in the past. Therefore, the simple past tense 'finished' is the correct verb form.
