BSF Head Constable Ministerial (HCM) Mock Test - 9 - BSF Head Constable MCQ

The correct answer is: Ceasefire.

Key Points

• The word "armistice" means a formal agreement between opposing sides in a war to stop fighting for a certain time; a truce. (युद्धविराम)
  • Example: The armistice was signed, bringing a temporary halt to the hostilities.
• "Ceasefire" also refers to a temporary suspension of fighting, typically one that is officially declared in a war or conflict. (युद्धविराम)
  • Example: Both sides agreed to a ceasefire to allow humanitarian aid to reach the affected areas.
• Hence, we can infer that the synonym for 'armistice' is 'ceasefire'.

Therefore, the correct answer is: Ceasefire.

Additional Information

Here are the other options explained along with their Hindi meanings and example sentences:

• Dispute (विवाद): An argument or disagreement, especially an official one between, for example, workers and employers or two countries with a common border.
  • Example: The two countries were locked in a dispute over the border for years.
• Bloodshed (रक्तपात ): The killing or wounding of people, typically on a large scale during a conflict.
  • Example: The revolution was marked by widespread bloodshed.
• Hostility (शत्रुता): Hostile behavior; unfriendliness or opposition.
  • Example: Their hostility towards the new management team was evident.

The correct answer is 'Option A' i.e. 'rapture'.
Key Points

• The underlined word "rapturously" is an adverb, but the sentence structure necessitates an adverbial phrase that begins with the preposition "with." Thus, an adjective or noun form is required after "with" to correctly modify the verb "listened."
• "Rapture" is a noun that perfectly fits the sentence, referring to a state of intense joy or pleasure, which aligns with how the audience experiences the school orchestra's performance.
• Using "rapture" after "with" corrects the sentence to indicate that the audience listened in a state of great joy or ecstasy.
• The correct form in this context should smoothly connect the listener's experience (the audience) with the verb (listened), and "rapture" is the suitable choice for expressing this meaning.

Therefore, the correct answer is- rapture.
Additional Information

• Option B ('raptures'): While also a noun, "raptures" in plural is less appropriate because the sentence calls for a singular form to match the collective sense of experiencing music.
• Option C ('raptured'): This is not correctly used in this context as "raptured" is a past participle and doesn't fit the grammatical structure required here.
• Option D ('rapturing'): This gerund form does not fit the required noun or adjectival phrase after "with" to describe the state of the audience's listening.

The correct answer is "Sturdy".
Key Points

• Strong means something or someone having great physical power, force, or potency. It can also be used to describe something that is able to withstand stress, pressure or damage.
  • Example: The weightlifter was able to lift the heavy barbell with his strong arms.
• Let us look at the meanings of all the options:
• Sturdy means having or showing physical strength and durability. It can be used to describe an object or a person that is strong and tough.
  • Example: The sturdy oak table was able to withstand the weight of the heavy books.
• Puny means weak, insignificant or small. It is used to describe something that is lacking in strength or size.
  • Example: The puny kitten was no match for the large dog.
• Small means little in size or amount. It is used to describe something that is not big or strong.
  • Example: The small child was unable to lift the heavy box.
• Straight means not bent or curved, or direct. It is used to describe something that is not crooked or weak.
  • Example: The straight line was the shortest distance between the two points.
• So, it is clear that Sturdy and Strong are similar in meaning.

Therefore, the correct answer is option A.

The correct answer is 'was acting in accordance with'.
Key Points

• The error lies in the usage of the Simple Past Tense and the preposition 'to'.
• The phrase “in accordance to,” although sometimes seen in informal speech, is grammatically incorrect.
• “In accordance with” is correct when referring to something that we are complying with, such as a law, a contract, or advice.
  • Example - In accordance with your request, I am sending a copy of my book.
• Thus, the phrase 'in accordance' should be followed by preposition 'with' not 'to'.
• Also, 'was acted' needs to be replaced by 'was acting' i.e., the Past Continuous tense.
• The Past Continuous tense is used to denote an action going on at some time in the past. The time of the action may or may not be indicated.
  • Structure of the Past continuous tense: Subject + was/were + ing form of the verb + object.
  • Example - We were listening to the radio all evening.
• Correct sentence: She was acting in accordance with the director's advice.

Hence, the correct answer is option (B).

The correct answer is "examples"
Key Points

• Option B) examples is the most appropriate word to fill in the blank because it accurately describes the Taj Mahal as a representation of a particular style or type of architecture. The passage states that the Taj Mahal is considered one of the finest examples of Mughal architecture, a blend of Indian, Persian, and Islamic styles. An example is "a particular instance or case that is used to illustrate a particular point or to show how something works or is done", so it is a suitable word to describe the Taj Mahal as a representation of Mughal architecture.
• Option A) patterns means a "regular or repeated arrangement, design, or sequence", which is not relevant to the Taj Mahal as described in the passage.
• Option C) ideals means a "standard of perfection or excellence", which is not relevant to the Taj Mahal as described in the passage.
• Option D) excuses means "a reason or explanation given to justify a fault or offense", which is not relevant to the Taj Mahal as described in the passage.
• Therefore, option B) examples is the most appropriate word to fill in the blank.

Correct paragraph: The Taj Mahal is a white marble mausoleum located in Agra, India. It was built by the Mughal Emperor Shah Jahan in memory of his beloved wife, Mumtaz Mahal, who died during childbirth. The Taj Mahal is considered one of the finest examples of Mughal architecture, a blend of Indian, Persian, and Islamic styles. It is a UNESCO World Heritage Site and is one of the most visited tourist attractions in the world, with millions of visitors each year.

Hence, "479" is the correct answer.

The pattern followed here is:
The prime number series followed here which start with 19.

Hence, the correct answer is "174".

The pattern followed is:

Similarly,

Hence, the correct answer is "NLVR".

1. L is sitting third to the left of O.

2. M is sitting second to the right of O

3. N is sitting second to the right of P.

4. P is the only one sitting between Q and O.

As we can see the diagram L is sitting between M and Q.

Here, we use the table given below:

Given:
YWE, WTG, TOJ, OHO, HYV, ?
Logic: Letters are decreasing and Increasing in Prime Number order (2, 3, 5, 7, 11) in the First and the Third column respectively.
And;
Letters are Decreasing in Odd Number Order (3, 5, 7, 9, 11) in Second column.
The logic followed in the given series:

Here, 'WNG' will be the next term as per the logic.
Hence, the correct answer is "WNG".

Calculation:

Convert the given ratios to a common format for easy comparison:

can be written as 3 ∶ 2 (by finding a common multiple).

can be written as 7 ∶ 4 (by finding a common multiple).

From the given ratios, a ∶ b = 3 ∶ 2 and b ∶ c = 7 ∶ 4.

First, make the 'b' term the same in both ratios. The least common multiple (LCM) of 2 and 7 is 14:

a ∶ b = 3 ∶ 2 can be written as 3 × 7 ∶ 2 × 7 = 21 ∶ 14.

b ∶ c = 7 ∶ 4 can be written as 7 × 2 ∶ 4 × 2 = 14 ∶ 8.

Now combine the ratios to get a ∶ b ∶ c:

⇒ a ∶ b ∶ c = 21 ∶ 14 ∶ 8.

∴ The ratio a ∶ b ∶ c = 21 ∶ 14 ∶ 8.

Given:

X, Y and Z invest capitals in the ratio 18 ∶ 20 ∶ 25.

After 6 months, X increases his capital by 331/3% and Y decreases his capital by 50%, and no change in the capital of Z.

The profit is Rs. 15.25 lakhs at the end of the year.

Concept used:

1. Profit in a partnership business is always distributed in the ratio of capital investment.

2. 331/3% = 1/3 ​

Calculation:

So, the new ratio of their investment on the annual basis

⇒ {(18 × 6) + (18 + 18 × 1/3) × 6} : {20 × 6 + (20 - 20 × 50%) × 6} : (25 × 12)

⇒ 252 : 180 : 300

⇒ 21 : 15 : 25

Now, the Y's share of the profit

⇒ 15.25 lakhs × 15/(21 + 15 + 25)

⇒ 3.75 lakhs = Rs. 3,75,000

∴ The share of Y in the profit of Rs. 15.25 lakhs at the end of a year is Rs. 3,75,000.

Given:

tanθ + cotθ = 8

Concept used:

cotθ = 1/tanθ

x² + 1/x² = (x + 1/x)² - 2

Calculation:

tanθ + cotθ = 8

tanθ + 1/tanθ = 8

tan2θ + cot2θ

We can write this as tan2θ + 1/tan²θ using (cotθ = 1/tanθ)

By using the formula: x2 + 1/x2 = (x + 1/x)2 - 2

tan2θ + 1/tan2θ = (tanθ + 1/tanθ)² - 2

tan2θ + 1/tan2θ = (8)2 - 2

tan2θ + 1/tan2θ = 64 - 2

tan2θ + 1/tan2θ = 62

tan2θ + cot2θ = 62

∴ Option D is the correct answer.

Formula used:

1 + cot2 θ = cosec² θ

1 + tan² θ = sec² θ

cosec θ = 1/sin θ and sec θ = 1/cos θ

Calculation:

(1 + cot2 θ) (1 + cos θ) (1 - cos θ) - (1 + tan2 θ) (1 + sin θ) (1 - sin θ)

⇒ cosec2 θ (1 - cos² θ) - sec² θ (1 - sin² θ)

⇒ cosec2 θ . sin² θ - sec2θ . cos² θ

⇒ 1 - 1 = 0

Given:

In a 60 litres solution of spirit and water, the ratio of spirit and water is 8 ∶ 7.

When 12 litres of the solution is drawn off and 8 litres of water is added.

Calculation:

Initial amount of spirit in the mixture = 60 × 8/(8 + 7) = 32 litres

Initial amount of water in the mixture = 60 × 7/(8 + 7) = 28 litres

Amount of spirit in 12L of mixture = 12 × 8/(8 + 7) = 6.4 litres

Amount of water in 12L of mixture = 12 × 7/(8 + 7) = 5.6 litres

Final amount of water in the resulting solution = 28 - 5.6 + 8 = 30.4 litres

Final amount of spirit in the resulting solution = 32 - 6.4 = 25.6 litres

Now, the final ratio = 25.6 : 30.4 = 16 : 19

∴ The required ratio is 16 : 19.

Calculation:

Distance between A and B = 220 km

A starts moving towards B at 11 AM with speed of 40 km/hr

B starts moving Away from A at 12 PM with speed of 30 km/hr

At 12 PM A travelled 40 km

Now distance reduced to 180 km

Now both starts moving and difference between their speed is 10 km/hr

Since A’s speed is 10 km more than B so they will meet after 180 km / 10 km/hr = 18 hr = at 6 AM on next day

∴ Option 4 is the correct answer.

Formula:
Total distance covered = Speed × Total time
Calculation:
Total distance covered by the train in 1.2 min = 1.2/60 × 90 = 1.8 km or 1800 m
According to the question, the train enters and leaves the tunnel-
⇒ Total distance train needs to cover to get out of the tunnel = Length of train + Length of tunnel
∴ Length of tunnel = 1800 m - 1200 m = 600 m
⇒ Difference in the length = 1200 - 600 = 600 m
The difference in the length is 600 m.

Given:

CI for 2 years = ₹2544

SI for 2 years = ₹2400

Formula used:

SI = (Principle × Rate × Time) ÷ 100

Concept Used:

CI for 2 years = SI for 2 years + (SI × r/100)

Rate = × 100

Calculation:

According to the question,

CI for 2 years - SI for 2 years = 2544 - 2400 = ₹144

SI of two years = ₹2400

⇒ SI of one year = ₹2400 ÷ 2 = 1200

⇒ Rate = (144/1200) × 100 = 12%

The rate is 12% and SI is 1200 for one year

⇒ Principle = 1200 × (100/12) = ₹10,000

Thus, the total savings of Harry is

⇒ 10,000 × 2 =20,000

⇒ 70% of total savings = 20,000 × (70/100)

⇒ 70% of total savings = ₹14,000

∴ The value of 70% of total savings of Harry is ₹14,000.
