SSC CGL English (Tier II) Mock Test - 9 - SSC CGL MCQ

Given:

The average of numbers is .

Sum of observations = average numbers of observations

Sum of all numbers

Later it was found that a number was wrongly taken as .

Correct sum

Correct Average  

Given:
First we will calculate mean:

Given:

and

Formula:

According to the given formula,

As we know,

Given,

The length of a pendulum = 60cm and an arc of length = 16.5 cm

∴ The angle through which it swings = 15° 45′

Given,

Sum of 5 consecutive integers is S.

Let the smallest of these 5 numbers be x.

5 consecutive numbers will be .

According to the question,

Largest of these 5 number

Given:
The length of a room = 21/16 times it's breadth.
The breadth is  4/3 times its height.
We know that,
Longest diagonal of the room 
Where, l = length, b = breadth and h = height
Let the value of Height = 12
According to the question,

As data given in the question,
Product of two natural number
Division of number  = 19/28

Let assume the two natural numbers as x and y,

Substitute the value in Eq (i).

Given:

Concept used:

Calculation:

According to the question,

Now comparing both side we get,

Given:

Length cm

Breadth cm

If we revolve sheet around length ,

Then

As we know,

Circumference of cylinder formed  length of rectangular sheet

cm

Volume 

cm

We have the equations: and

The equations are equivalent to the matrix equation AX = B

So, the equations have only one root.

Let f(θ) = 7cos²θ + 5sin²θ

= 2cos²θ + 5cos²θ + 5sin²θ 

= 2cos²θ + 5(cos²θ + sin²θ)

= 2cos²θ + 5

[∵ cos²θ + sin²θ = 1]

As we know, 0 ≤ cos²θ ≤ 1

⇒  0 ≤ 2cos²θ ≤ 2

⇒  0 + 5 ≤ 2cos²θ + 5 ≤ 2 + 5

⇒ 5 ≤ 2cos²θ + 5 ≤ 7

⇒ 5 ≤ f(θ) ≤ 7

So, Maximum value of function is 7.

Given:

Formula:

a³ + b³ = (a + b)(a² + b² – ab)

Calculation:

⇒ (x² + 9) = 3x

⇒ x² + 9 – 3x = 0      ----(1)

Now,

x³ + 3³ = (x + 3)(x² + 3² – 3x)

From equation (1):

⇒ x³ + 3³ = (x + 3) × 0

⇒ x³ + 3³ = 0

⇒ x³ = – (3)³ = – 27

∴ The value of x³ is – 27.

On arranging the given words in alphabetical order, we get:

1. Pope
2. Poppy
3. Populace
4. Popular
5. Population

Therefore, the word which will come at fifth position will be 'Population'.

According to grammar, 'in' is a preposition and we know that after the preposition we usually use the prepositional object that can be a noun /pronoun/gerund.

In this case, we need to use a gerund.

So the correct sentence is- She is not interested in eating sweets.

In the given options "Abstinant" is incorrectly spelt. Its correct spelling is "Abstinent."

Abstinent: Total avoidance of something.

​Example: He has been abstinent from alcohol for two years. 

​Therefore, as per the points mentioned above, we find that the correct answer is Abstinent.

The correct answer is 'laboratary'.

'Laboratary': There is no such word in English or we can say that there is some spelling mistake in this word, correct spelling is 'Laboratory'.

Laboratory: a room or building that is used for scientific research, testing, experiments, etc. or for teaching about science

Example: The blood will be tested by a laboratory technician.

After those first two cargo missions, SpaceX will launch two manned missions alongside two additional cargo-only flights to begin setting up a propellant production plant. At that plant, water and carbon dioxide will be converted into liquid methane and liquid oxygen, which fuel the rocket's engines.

From the highlighted part, it is obvious that both liquid methane and liquid oxygen will be used to power the Starship rocket while returning from Mars. Liquid hydrogen is nowhere mentioned in the passage.

Refer to:
For its very first Mars missions, SpaceX will land at least two unmanned cargo ships on the Red Planet before sending any humans there, Wooster said.
The highlighted part confirms that the statement given in option A is false.

Refer to:
After those first two cargo missions, SpaceX will launch two manned missions alongside two additional cargo-only flights to begin setting up a propellant production plant.
Robots and A.I. were not mentioned in the passage. Besides, the highlighted part confirms that the the statement given in option B is false.

Refer to:
As NASA works toward its long-term goal of establishing a human settlement on Mars, SpaceX is fleshing out its plans to help NASA make that dream a reality.
Jaxa and ISRO are nowhere mentioned in the passage, and the highlighted part confirms that SpaceX tied up with NASA.
So, the statement given in option D is clearly false.

Refer to:
Before Starship can launch to Mars, it will start off launching commercial satellites as early as 2021, followed by a manned flight around the moon in 2023.
Starship is being developed by SpeceX and the highlighted part confirms that the statement given in option C is true.

A news broadcast becomes more immediate when people could actually see the scene ...

The computer performs five basic operations which are input, process, output, storage, and control. The major characteristics of a computer are high speed, accuracy, diligence, versatility, and storage.

• Input captures the data from the user, or it is the process of accepting data or information, by using input the computer can do any process.
• The process is to convert the input into output.
• Output is the display or output of the result from processing.
• The storage stores the data or information or instructions, for future use.
• Control directs the manner and sequence of all the operations performed in a computer system.

Multimedia projectors of a computer are used for training presentations. A multimedia projector is a compact, high resolution, full-colour projector capable of projecting text, images, video and audio content. Typically the projector will feature inputs for a computer, DVD player, VCR, CD player and storage device.
