Indian Navy Agniveer Mock Test - 3 - Indian Navy Agniveer MCQ

The correct answer is "A"

Key Points

• The error lies in part 'A' of the sentence because 'chosen' is used which is the past participle form of the verb 'choose' indicating that the action is completed and in the past.
• Here, the verb 'choose' is used in the context of the action that is still ongoing or current.
• Structure of the correct sentence is:
  • Subject + verb (3rd form) + Object + Preposition + Object
• Hence, 'chose' must be used instead of 'chosen' to make the sentence correct.

Thus, option 1 is the correct answer.

Correct Sentence: The company chose her for the position due to her qualifications.

The correct answer is "B"

Key Points

• The error lies in part 'B' of the sentence because 'more valuable' is used instead of 'most valuable'.
• The sentence is expressing that this painting is considered to be one of the most valuable in the museum's collection.
• 'Most' is used to indicate the superlative form, meaning 'the most' in this context.
• Hence, 'most valuable' must be used instead of 'more valuable' to make the sentence correct.

Thus, option 3 is the correct answer.

Correct Sentence: This painting is considered to be one of the most valuable in the museum's collection.

The correct answer is 'Both Landlords and Police'.

Key Points

• The passage is a non-fiction piece on the theme of 'freedom'. The purpose of this passage is to explain, analyse, define or clarify something—to provide us with information and to show the how and why of things.
• Read the lines of the passage- "Your landlord may refuse to let you live on his estate if you go to chapel instead of to church, or if you vote for anyone but his nominee, or if you practise osteopathy or if you open a shop."
• After reading the above lines from the passage we can conclude that people who exert pressure on man’s freedom is a landlords.
• The passage mentions that people who exert pressure on man's freedom are landlords and employers, who have the power to dictate various aspects of their tenants' and employees' lives. Additionally, the passage notes that laws enforced by the police also restrict freedom, but reasonable laws can actually increase freedom by protecting individuals from harm. Therefore, both landlords and police are correct answers.

Therefore, the correct answer is Option 4.

The correct answer is 'punishes'.

Key Points

• The passage is a non-fiction piece on the theme of 'freedom'. The purpose of this passage is to explain, analyse, define or clarify something—to provide us with information and to show the how and why of things.
• Read the lines of the passage- "If the laws are reasonable and are impartially administered, you have no reason to complain, because they increase your freedom by protecting you against assault, highway robbery and disorder generally."
• After reading the above lines from the passage we can conclude that if a person does not follow the law and order he/she will suffer in future in the form of assault, highway robbery and disorder. Hence, The author does not favour the non-violent means to get our demands conceded, because the person doing so is the ultimate sufferer.

Therefore, the correct answer is Option 1.

The correct answer is 'between'

Key Points

• Between as a preposition means in or into the space that separates two places, people, or objects:
  • Ex- The town lies halfway between Rampur and Faizabad.
• Among two or more people or things:
  • Ex- The money was divided equally between them.
• ​If something is between two amounts, it is greater than the first amount but smaller than the second:
  • Ex- He weighs between 55 and 60 kilograms.
• In the given sentence Between means the space that separate Russ and Ross.
  

As per the points mentioned above the correct answer is 'Option 3'

Confusion Points

• There are a few different ways among and between are used.
  • The most common use for among is when something is in or with a group of a few, several, or many things.
  • The most common use of between is when something is in the middle of two things or two groups of things.

The correct answer is Fickle.Key Points

• “Loyal” means someone who is very trustable.
• “Fickle” means who is never fixed on anything, especially when it comes to trust or loyalty.
  • Example: You should never trust a fickle-minded person.
• Therefore, “Fickle” is the correct antonym for “Loyal”.

Additional Information

The meaning and usage of the other words are as follows:

• “Ardent” means very passionate about something.
  • Example: He is an ardent follower of Virat Kohli.
• “Stupid” means foolish.
  • Example: I have never encountered such a stupid excuse for not coming to the party.
• “Tragic” means heartbreaking or sad.
  • Example: His failure in the exam after so much hard work was very tragic.

The correct answer is "The shooting of the hideous movie will have been finished by Jennifer Lawrence"

Key Points

• To form the passive voice, you need to use the verb be in the same tense as the active voice, followed by the past participle of the main verb.
• The active voice sentence is in the future perfect tense, which uses will have + past participle.
• Therefore, the passive voice sentence should use will have + been + past participle.
• This is an example of the future perfect tense.
• Rules for this type of conversion:
  • Active: Subject + will have been + V-III + Object
  • Passive: Object + will / shall have been + V-III + by + Subject
• While comparing with the basic structure:
  • Jennifer Lawrence(subject)
  • finish(verb)
  • The shooting of the hideous movie(object)

CONCEPT:

• AND Gate: The Logic AND Gate is a digital logic circuit whose output HIGH only when all the inputs are 1 (HIGH) otherwise output will be LOW.

• OR Gate: The Logic OR Gate is a digital logic circuit whose output goes HIGH only when any one or more than one of its inputs is HIGH.

• NOT Gate: The Logic NOT Gate is the most basic of all the logic gates and is often referred to as an Inverting Buffer or simply an Inverter.

EXPLANATION:

• OR Gate: The Logic OR Gate is a digital logic circuit whose output goes '1' HIGH only when any one or more than one of its inputs is '1' HIGH.

• So the correct answer is option 2.

Concept:

Coulomb's law

• It states that the magnitude of the electrostatic force F between two point charges q1 and q2 is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance r between them.

• It is represented mathematically by the equation:

⇒F=14πϵ0q1q2r2

Where ϵ0 is the permittivity of free space (8.854 × 10-12 C2 N-2 m-2).

The expression is also written as

k is constant having value 9 × 10 ⁹ N r² C^-2

Superposition Principle

• The Forces in each charge are obtained using this Principle
• The total force on a given charge is the vector sum of the individual forces exerted on the given charge by all the charges.
• This is used to calculate the following parameter at the observation point, to any configuration of charges.

• The third charge has no role to play when we are calculating the force between just two charges.

Calculation:

So, the Given situation can be represented in the following diagram.

Here let one unit distance be r

Distance between 4q and q is r

Distance between Q and q is r / 2

Now, we have to calculate the net Force acting on charge q

First, we will find the force between 4q and q charge

 -- (1)

Now we will find the force between Q and q

 --- (2)

Net force is zero. So,

F_4q + F_Q = 0

⇒ FQ = - F4q

⇒ Q = - q

So, the correct option is - q.

Concept:

• When a wave travels from one medium to another medium, wavelength, and speed amplitude change.
• But the frequency remains constant because it is a property of the source and it only deepened on the source of the wave.
• The speed of light depends on the optical density (refractive index) of the medium.

Refractive index:

• ​It is defined as the ratio of the speed of light in air to the speed of light in the medium.
• Formula, refractive index,  where, c = speed of light in air, v = speed of light in the medium.
• It is a dimensionless physical quantity.
• Whereas, density is defined as the mass per unit volume.
• The refractive index of air is 1 and the refractive index of glass is 1.5.

Explanation:

• The speed of light depends on the optical density (refractive index) of the medium.
• Light travels faster in a medium with a lower refractive index than in one with a higher refractive index.
• As glass is optically denser than air, light travels slower in glass than in air.
• Or the refractive index of air is less than that of glass.

​Hence, the correct option is 1.

CONCEPT:

• Simple Pendulum: An ideal simple pendulum consists of a heavy point mass body (bob) suspended by a weightless, inextensible and perfectly flexible string from rigid support about which it is free to oscillate.
• For a simple pendulum, the time period of swing of a pendulum depends on the length of the string and acceleration due to gravity.

The above formula is only valid for small angular displacements.

• The force which acts to bring a body to its mean position/equilibrium position is called a restoring force.
• For example: The spring force is a restoring force because it always applies a force towards the equilibrium point.

Where,T = Time period of oscillation, l = length of the pendulum, and g = gravitational acceleration

CALCULATION:

Given that: Acceleration due to gravity on earth = g, Acceleration due to gravity on moon = g', and Thus from the given statement, g = 6g'

• This shows that acceleration due to gravity on earth will be greater than that on the moon
• And from the above explanation, we can see that time period of oscillation for a simple pendulum is inversely proportional to acceleration due to gravity acting on it.

i.e.,

• Hence from this, we can conclude that the time period of oscillation kept on the moon will be greater than that of the earth since acceleration due to gravity on the moon is less than that of earth

Concept:

• For any base b which is a transcendental number the logarithm log_bn of every integer n ≥ 2 is an irrational number.
• A rational number is a number, which can be written as p/q where p & q are integers and q ≠ 0.

Formula used:

• log mn = log m + log n
• log_aa = 1
• log_aⁿb = (1/n) log_ab

Calculation:

Statement:1 log₁₀50 is a rational number.

log1050 = log1050 = log10(5 × 10)

log1050 = log105 + log1010

log1050 = log105 + 1

As discussed, log105 is an irrational number, log1050 will be also irrational.

Statement:2 log100 10 is an irrational number.

log₁₀₀10 = log_10²10 = (1/2)log₁₀10 = 1/2

Which is a rational number.

∴ Both statements are incorrect.

Calculation:

It is given that each set A_i contains 5 elements and

∴ Number of elements is S, n(S) = 30×5 = 150

But, it is given that each element of S belong to exactly 10 of the A_i's.

∴ Number of distinct elements in S =  = 15

It is also given that each set B_j contains 3 elements and

∴ Number of elements is S, n(S) = 3×n = 3n

Also, each element of S belongs to exactly 9 of the B_j's.

∴ Number of distinct elements in S =  =

∴  = 15

⇒ n = 45

∴ The required value of n is 45.

Concept:

Number of ways of choosing r objects from n objects = nCr =

Calculation:

The number of ways of forming a committee with atleast one woman

= Total number of ways of forming the committee - (ways of forming a committee with no woman)

If a five-membered committee consists of no woman,

⇒ The committee consists of exactly 5 men and 0 women.

Number of ways of choosing 5 men from 6 men

⇒ 6C5 =  = 6

And the total number of ways of choosing 5 members from 10 members (6 men and 4 women)

⇒ 10C5 =  = 252

⇒ The number of ways of forming a committee with atleast one woman = 252 - 6

⇒ The number of ways of forming a committee with atleast one woman = 246

∴ The correct answer is option (2).

∴ The correct answer is option (1).

Calculation:

Given: x² + 3|x| + 2 = 0

Case - 1: when x ≥ 0

⇒ x² + 3x + 2 = 0

⇒ x² + x + 2x + 2 = 0

⇒ (x + 1) (x + 2) = 0

⇒ x = - 1 or - 2

∵ x ≥ 0 ⇒ The given quadratic equation has no real roots for x ≥ 0.

Case - 2: when x < 0

⇒ x² - 3x + 2 = 0

⇒ x² - x - 2x + 2 = 0

⇒ (x - 1) (x - 2) = 0

⇒ x = 1 or 2

∵ x < 0 ⇒ The given quadratic equation has no real roots for x < 0.

Concept:

Calculation:



∴ The correct option is (2).

Given:

The probabilities of the occurrence of two events E and F are 0.25 and 0.50 respectively.

The probability of their simultaneous occurrence is 0.14.

Concept used:

By definition of P(E or F) under axiomatic approach(also called addition theorem) we know that: P(E∪F) = P(E) + P(F) – P(E∩F)

Calculation:

P(E) = 0.25

P(F) = 0.50

P(E ∩ F)= 0.14

The probability that neither E nor F occurs is = P(E' ∩ F')

⇒ [1 - P(E ∪ F)]

We know that P(E ∪ F) = P(E) + P(F) - P(E ∩ F)

⇒ 0 .25 + 0.50 - 0.14

⇒ 0.61

Now, P(E' ∩ F')

⇒ 1 - 0.61

⇒ 0.39

∴ The required answer is 0.39.
