SSC CGL English (Tier II) Mock Test - 7 - SSC CGL MCQ

Given:

The medians QT and RS intersect at right angles.

QT = 18 cm, RS = 27 cm

The two medians intersect at G. Hence G is the centroid of the triangle and the centroid divides the median in the ratio 2 : 1

∴ QG : GT = 2 : 1 ⇒ QG = 18 ×  = 12 cm 

Also, RG : GS = 2 : 1 ⇒ GS = 27 × = 9 cm

∴ In ΔGQS, ∠QGS = 90° (∵ medians intersect at 90°)

Using Pythagoras theorem,

∴ The length of QS = 15 cm.

Given numbers are .

Let the sum of all their possible products be 'x'.

As we know,

Also,

So, we can write,

Square of sum of ' n ' numbers = Sum of their squares +2

(Sum of all possible products taken two at a time)

Now,

Square of sum of given numbers

Sum of their squares:

Given:
698x3291y is a 9-digit number divisible by 99.

As we know,
To check the divisibility by 9, the sum of the digits of the number of should be multipole of 9.
To check the divisibility by 11, the difference of the sum of the digits at the unit's place and the ten's place of the number should be 0 or a multiple of 11.
The number is divisible by 99 means that the number is divisible by 11 and 9 (factor of 99 ).

Divisibility by 9,
The sum of the digits of the number should be a multiple of 9
⇒ 6 + 9 + 8 + x + 3 + 2 + 9 + 1 + y 
⇒ for the above expression to be a multiple of 9, the value of x + y = 7      ---(1)

Divisibility by 11,
(6 + 8 + 3 + 9 + y) - (9 + x + 2 + 1)
⇒ 26 + y - 12 - x 
⇒ (14 + y - x) → this should be either 0 or a multiple of 11
⇒ Lets take (14 + y - x) = 0
⇒ x - y = 14, but on solving this with equation (1), this will not give the integer value of x
So, 14 + y - x = 11 ⇒ x - y = 3      ---(2)
On solving (1) and (2),
x = 5 and y = 2
∴ The given nine-digit number is 698532912
Now,

∴ The value of the given expression is 9.

Given,

Sum of two numbers is 23.

The product of two numbers is 216.

As we know,

a² + b² = (a + b)² - 2ab

Let p and q be the numbers

p + q = 23

pq = 216

By using the above formula

p² + q² = (23)² - 2 × 216

p² + q² = 529 - 432 = 97

The sum of the squares of the number is 97.

Given,

The simplest triangles are BFG, CGH, EFM, FMG, GMN, GHN, HNI, LMK, MNK and KNJ i.e. 10 in number. The triangles composed of three components each are FAK and HKD i.e. 2 in number. The triangles composed of four components each are BEN, CMI, GLJ and FHK i.e. 4 in number. The triangles composed of eight components each are BAJ and CLD i.e. 2 in number. Thus, there are 10 + 2 + 4 + 2 = 18 triangles in the given figure.

The logic followed is here:

1^st to 2^nd diagram:

(1) Rectangle length side both arrows change direction.

(2) Triangle left side arrow change here direction.

(3) Circle rotates anti-clockwise direction.

2^nd to 3^rd diagram:

(3) Rectangle width side both arrows change direction.

(4) Triangle left side arrow change here direction.

(5) Circle rotates anti-clockwise direction.

3rd to 4th diagram:

(6) Rectangle length side both arrows change direction.

(7) Triangle left side arrow change here direction.

(8) Circle rotates anti-clockwise direction.

Similarly,

4^th to 5^th diagram:

(6) Rectangle width side both arrows change direction.

(7) Triangle left side arrow change here direction.

(8) Circle rotates anti-clockwise direction.

The pattern is as follows:

Z - Y = A i.e.26 – 25 = 1 (the positional value of A)

Z - O = K i.e.26 – 15 = 11(the positional value of K)

Z - K = O i.e.26 – 11 = 15 (the positional value of O)

Z - I ≠ N i.e.26 – 9 = 17 ≠ 14 (the positional value of N)

Therefore, ZIN is the different one.

So, ‘D’ is sitting opposite C.

The pattern here followed is:

In the given options, the most appropriate answer is 'Had I been in.' Had been is the past perfect continuous form of the verb.

• Had been is used to identifiy actions that both began and ended in the past.
• It is used in the past perfect and past perfect progressive tenses.
• Had been indicates something is closed and completed.

The sentence structure is as follows:

• Had+been+ing 
• Example: I had been working.

​Correct sentence: Had I been in your place, I would not have accepted his suggestion.

The correct answer is 'My new slippers were chewed by the little puppy'.

The instructions given below should be followed while changing an assertive sentence to a passive voice.

• Find the subject and object of the sentence and exchange their places; make changes in their cases as well if subject and object are pronouns.
• Use preposition 'by' before the agent.
• Use an appropriate helping verb in passive form according to the tense of the active form. 
• Always use the third form of the main verb in passive form.
• At last line up the remaining part.

Now let us look at the question:

The subject will become ''my new slippers''.

The active form contains the past participle form of verb i.e. chewed so the passive form will be in past tense form.

Option (A) is in past continuous form.

Option (B) contains 'can' which is incorrect.

Option (D) is in present continuous form.

It is appropriate to use in, have, the, a respectively in the blank spaces of the sentence. So the meaningful sentence would be:

There are no sparrows chirping in the cities anymore. All have either died or flown far away as they had no space in the growing concrete jungle. The cunning pigeons have become a menace.

The given passage discusses the importance of analyzing one's own concept to achieve success.

Let us refer to this line from the passage, "We must analyze what makes us happy and what ______(3)______ us".

According to the given sentence, the blank must contain a word that represents analyzing what makes us happy and encourages us.

So, the word 'motivates' fits correctly in the given blank as it means 'provide (someone) with a reason for doing something; encourage'.

Complete Sentence: We must analyze what makes us happy and what motivates us.

According to the passage, "It was during these tiring times that she realized how difficult it would be for abandoned children or orphans and decided to do something for them. Her first adopted child was Deepak, whom she found on a railway track. Quite soon she had adopted sixteen children."

According to the passage, "She set up four NGOs to accomplish her mission."

According to the passage, "So Sindhutai started taking care of children in return for some food. Looking after these kids soon became the mission of her life."

So, it is concluded that 'she got the most brilliant children admitted to public schools' is not true according to the passage.

The study showed that temperatures would rise by almost four times that amount, to 2.2 degrees Celsius above current readings, if emissions were allowed to continue on their present course.

Sea-level rise due-to thermal expansion as water temperatures warmed would be 14 centimeters (about 5.5 inches) instead of 22 centimeters (8.7 inches). Also, Arctic ice in the summertime least shrink by about a quarter in volume and stabilize by 2100, as opposed to shrinking at least three-quarters and continuing to melt, and Arctic warming would be reduced by almost half.

Thus, all of the given options are correct.

The correct answer is 'critical point.'

Idiom: Crux of the matter means the basic, central or critical point of an issue, topic, or problem.

Example: The real crux of the matter was finding out why her daughter felt the need to take drugs.

From the given options, the fourth option is the most appropriate meaning of the given idiom.

Providance has the wrongly spelt word. 

The correct spelling of the word is ‘providence’ which means an influence that is not human in origin and is thought to control people's lives.

The correct sentence is: I shall be honoured if you accept my offer.

The sentence is in the First Conditional. The First Conditional is used to talk about the result of an imagined future situation, when we believe the imagined situation is quite likely.

​Structure: If + present simple + modal verb with future meaning (will, shall, might etc.)

• ​Ex: If he gets a job in Liverpool, he will have to get up early. It’s a long drive.

​The question sentence has 'would' in 'if-clause', which should be improved.

Option (C): i.e., 'if you accept' has 'if-clause' in present simple, therefore, it is the correct improvement

The correct pair is (a) - (iv), (b) - (i), (c) - (ii), (d) - (iii)

Differences in the heating and cooling of the earth's surfaces and the cycles that develop daily or annually can create several common local or regional winds. These blow only during a particular period of the day or year in a small area. According to the nature of air, air can be divided into two parts- cold local wind, and warm local wind.

Mistral: In Spain and France, it is a chilly, dry wind that blows from the northwest to the southeast. It blows during the winter months in the alps region. Due to the Rhone River's presence, these winds are channelized towards the Rhone valley. It causes a certain drop in temperature.

Purga: It is a cold and dry local wind. It is blowing in Russia and over the Tundra.

Harmattan: It is hot and dry local wind. It is blown in West Africa, from Sahara to Guinea.

Pampero: It is cold polar air. It blows from the southern pampas to the southernmost parts of Argentina and Brazil.

Huge cracks which are found in deep ocean basins are called ocean trench.

Ocean trenches are steep depressions in the deepest parts of the ocean where old oceanic crust from one tectonic plate is pushed beneath another plate, raising mountains, causing earthquakes, and forming volcanoes on the seafloor and on land.

Zoji La pass connects Srinagar and Leh. Zoji La is a mountain pass located in the Himalayas in Ladakh. It connects the Kashmir Valley to its west with the Dras and Suru valleys to its northeast and the Indus valley further east.

Zoji La pass is the lifeline that keeps the people of Ladakh in touch with the rest of the world.

Hyder Ali established a modern arsenal at Dindigul with the help of French experts. He also modernized the army. With the help of the French, he established a modern armory at Dindigul. Hyder Ali was not responsible for these kinds of changes in the Kingdom of Mysore. A new calendar, a new system of coinage and a new scale of weight and measure were introduced by Tipu Sultan.

A shelterbelt is the planting of trees or shrubs planted in such a manner as to provide shelter from the wind and to protect soil from erosion.

• They are commonly planted in hedgerows around the edges of fields on farms.
• Desertification is land degradation in arid, semiarid, and dry subhumid areas resulting from temporary climatic crises.

Concept:

IPv4 address: 32 bits

IP address = Network ID + Host ID

Network ID + Host ID = 32

PREFIX is the part of the Network ID

IPv4 classification:

In Classful address starts with 110 is class C because class C first 3 bits is reserved

To get last address make all remaining host Id part and network id part as 1

(1101 1111.11111111. 11111111.11111111)₂ = 223.255.255.255.255

Therefore, class of IP address has the last address as 223.255.255.255 is C.
