BSF Head Constable Ministerial (HCM) Mock Test - 4 - BSF Head Constable MCQ

The correct answer is "agreements."
Key Points

• "Arguments" means angry discussions between two or more people who disagree with each other. (विवाद, झगड़ा, बहस)
  • Example: Leela had arguments with her father about politics.
• ​"Agreements" means harmony or accordance in opinion or feeling. (राय या भावना में सामंजस्य या अनुरूपता)
  • Example: The dispute was settled by agreements that satisfied both sides.
• So, the word which is exactly opposite in meaning to the bracketed word is "agreements."
• Therefore, Option D is the correct answer.

Additional Information

• Option A: Altercation means a noisy argument or disagreement. (विवाद, झगड़ा, कहा-सुनी, अनबन)
• Option B: Negotiations involve discussion and compromise to reach an agreement, but they still involve some level of disagreement. (वार्ता (किसी निर्णय या समझौते पर पहुँचने के लिए लोगों में बातचीत)
• Option C: Feud means a prolonged and bitter quarrel between two parties. (दो व्‍यक्तियों या व्‍यक्ति-समूहों के बीच लंबे समय तक चलने वाला झगड़ा; पुश्‍तैनी रंजिश)

The correct answer is '(d)'.
Key Points

• The error lies in Part (d) of the sentence.
• 'Light' is the term for the brightness that is produced by a lamp, the sun, etc. which allows things to be seen.
• In most contexts, 'light' is uncountable and does not take a plural form.
• Lamps would not 'give lights'. They would 'give light'.
• Therefore, 'lights' in Part (d) should be replaced with 'light'.

Correct sentence: The bright lamps gave much light.
Additional Information

• While 'lights' does exist as a word in English, it does not have the same meaning as 'light'.
• 'Lights' can refer to pieces of equipment for producing light, such as lamps or ceiling lights.
• For example "The lights in the room were very bright".
• It does not generally refer to the brightness produced by these things, which is the context in this sentence.

The correct answer is "consumes"
Key Points
Look at the selected option within the context of the sentence:

• The blank should be filled with a verb because it follows the noun ""average person" on Earth"
• The sentence is in present tense so the verb must be in present tense.
• The blank follows a singular noun, that's why we will use "consumes".

Hence, the correct passage: Each human being has a legitimate claim to a sufficient and fair amount of Earth’s resources. But with a population approaching 8 billion, even if everyone adopted a relatively low material standard of living like the one currently found in Papua New Guinea, it would still push Earth to its ecological breaking point. Unfortunately, the "average person" on Earth consumes at a rate over 50% above a sustainable level.

The correct answer is 'concerned.'
Key Points

• The meaning of the word "Indifferent" is not interested in or caring about somebody/something. (व्‍यक्ति या वस्‍तु में रुचि या सोच-विचार से रहित; उदासीन)
• Let us see the meanings of the given options:
  • Precisely: exactly. (सही-सही)
  • Concerned: interested, worried and feeling concern about something. (किसी के लिए चिंतित और परेशान)
  • Discussed: to talk or write about something seriously or formally. ((लेख या भाषण के रूप में) गंभीर विचार-विमर्श करना)
  • Solely: not involving anyone or anything else; only. (केवल, एकमात्र)
• F rom the meanings of the given words, we can say that the word which is opposite of "indifferent" is "concerned."

Hence, the correct answer is Option B.

The correct answer is 'fertile'.
Key Points

• barren: not able to produce offspring or crops, or unproductive or unfruitful. (संतान या फसल पैदा करने में सक्षम नहीं, या अनुत्पादक या अनुपयोगी।)
  • Synonyms:- Sterile,Unproductive, Unfruitful, Desolate, Wasteland, Arid
  • Example:- The once-fertile land had become barren after years of drought and over-farming.
• "fertile" refers (used about land or soil) that plants grow well in (ज़मीन या मिट्टी) उपजाऊ
  • ​Synonyms:- productive
  • Example:- Fertile land is able to produce good crops or plants.

Hence, the correct answer will be Option D.
Additional Information

• desperate: out of control and ready to do anything to change the situation you are in because it is so terrible. अत्‍यधिक निराशा के कारण दुस्‍साहसी, निराशोन्‍मत
• parched: very hot and dry, or very thirsty बहुत गरम और सूखा, या बहुत प्‍यासा
• desolate: (used about a place) empty in a way that seems very sad (स्‍थान) निर्जन और अवसादपूर्ण

• For '$' - It is shifting in the anti-clockwise direction.

​

• For '#' - It is shifting in the anti-clockwise direction.

​

• For '?' - It is shifting in the anti-clockwise direction.

​

Consider the following Symbols:

P is the wife of Q,Q is the father of R,R is the brother of T,T is the wife of S.
The family tree for the above condition is given as follows:

Hence, the correct answer is "Mother in law".

Θ = | Hours x 30° - 11/2 x Minute |
H = 8 and M = 0
Θ = |11/2 x 0 - 30 x 8 |
Θ = | 0 - 240 |
Θ = 240°
Hence, '240°' is the correct answer.

Formula Used:
List Price (LP) calculation with discount:
Selling Price (SP) with 15% discount:  SP₁₅ = LP x (1 - (15/100))
Selling Price (SP) with 10% discount:  SP₁₀ = LP x (1 - (10/100)) 
Profit Percentage:  Profit % = SP - CP/CP x 100 
Calculation:
Given SP with 15% discount is ₹680:
⇒ 680 = LP x (1 - (15/100))
⇒ 680 = LP x 0.85 
⇒ LP = 680/0.85 
⇒ LP = 800
Now, SP with 10% discount:
⇒ SP₁₀ = 800 x (1 - (10/100)) 
⇒ SP₁₀ = 800 x 0.90
⇒ SP₁₀ = 720
Profit Percentage:
⇒ Profit % = 720 - 600/600 x 100
⇒ Profit % = 120/600 x 100
⇒ Profit % = 0.20 x 100
⇒ Profit % = 20 %
∴ The correct answer is 20% (B).

Given:

The average weight of 35 students in a class is 66 kg.

Formula Used:

New total weight = (Total weight of initial 35 students - Total weight of 6 students leaving) + Total weight of 11 students joining

Calculation:

Total weight of initial 35 students = 35 × 66

Total weight of 6 students leaving = 6 × 58.5

Total weight of 11 students joining = 11 × 68

New number of students = 35 - 6 + 11

New average weight = New total weight / New number of students

Total weight of initial 35 students = 35 × 66

⇒ 35 × 66 = 2310

Total weight of 6 students leaving = 6 × 58.5

⇒ 6 × 58.5 = 351

Total weight of 11 students joining = 11 × 68

⇒ 11 × 68 = 748

New total weight = (2310 - 351) + 748

⇒ 1959 + 748 = 2707

New number of students = 35 - 6 + 11

⇒ 40

New average weight = 2707 / 40

⇒ 67.675

∴ The correct answer is 67.675 (A).

Given:

Speed range 25 - 50 km/hr, fuel consume 20 mL per km

Speed range other than 25 - 50 km/hr, fuel consume 40 mL per km

Distance travelled at a speed of 40 km/hr = 10 km

Distance travelled at a speed of 60 km/hr = 30 km

Distance travelled at a speed of 30 km/hr = 10 km

Total distance travelled = 50 km

Concept used:

Speed = distance/time

Fuel consumed = fuel consumption rate per km × distance travelled

Calculation:

Distance travelled above the speed range of 25 – 50 km/hr = 30 km

⇒ Petrol consumed = 30 × 40 = 1200 mL = 1.2 L

Distance travelled other than speed range of 25 - 50 km/hr

= (10 + 10) = 20 km

⇒ Petrol consumed = 20 × 20 = 400 mL = 0.4 L

Given:

p varies inversely as the square of q

Formula used:

p = k/q2

Where k = integer

Calculation:

According to the question

⇒ 1.5 = k/(4.8)2

⇒ k = 1.55 × 23.04

⇒ k = 34.56

So,

When p = 24

⇒ 24 = 34.56/q2

⇒ q2 = 34.56/24

⇒ q2 = 1.44

⇒ q = 1.2

The possible value of q = ± 1.2

∴ The required result will be 1.2.

The logic followed here is:
‘ACE’ is written as ‘DGJ’

'ARMS' is written as 'DVRY'

Similarly, for ‘STOP’

So, ‘STOP’ is written as 'VXTV'.
Hence, the correct answer is "Option C".

The correct answer is Option A) i.e. 3, 1, 4, 2.

Key Points

• The sentence should start with the subject "Mandvi Beach," which is introduced in item 3.
• The phrase "is host to" naturally follows, indicating what Mandvi Beach is known for.
• The phrase "white, beautiful beaches" describes the main attraction, fitting well after "is host to."
• To complete the description, "with amazing seawater" supplements the beauty of the beaches.
• Finally, "for swimming and relaxing" adds the activities associated with Mandvi Beach, rounding out the sentence.
• Point 1: The subject "Mandvi Beach" should be introduced first as it is the main focus.
• Point 2: The phrase "is host to" sets up the expectation of introducing what Mandvi Beach offers.
• Point 3: Describing the beaches as "white and beautiful" provides a visual aspect.
• Point 4: "With amazing seawater" enhances the description of the beaches.
• Point 5: Ending with "for swimming and relaxing" indicates the activities available, completing the coherent idea.

Therefore, the correct answer is- 3, 1, 4, 2

Additional Information

• Option B (3, 4, 2, 1): This arrangement would read "Mandvi Beach is host with amazing seawater for swimming and relaxing to white, beautiful beaches," which disrupts the logical flow of the sentence.
• Option C (3, 1, 2, 4): This would place the activity "for swimming and relaxing" in the middle, missing the natural descriptive flow and making the sentence clunky.
• Option D (3, 2, 4, 1): This arrangement splits the description of the beaches and seawater inappropriately, leading to a less coherent sentence structure.

The correct answer is "Help"
Key Points
Let's look at the meaning of the word which is given in the question:

• Rescue- save (someone) from a dangerous or difficult situation.
• Example: firemen rescued a man trapped in the river.
• Help is the closest meaning of rescue

Hence, the correct answer is "option B"
Hinglish
Meanings in Hindi:

• Rescue- बचाव
• Example: firemen rescued a man trapped in the river.
• Defence- रक्षा
• Safety- सुरक्षा
• Command- आदेश

According to the given information:

1. Arpit started from his office and travelled 2 km towards west,
2. then turned right and travelled 2 km and then turned left and travelled 3 km.
3. From there he took a bus which travelled straight towards North and travelled 10 km by this bus and reached his home.

The following diagram can be deduced,

The shortest distance between his home and office:

The least distance will be the hypotenuse of triangles.

• Shortest distance (?²) = 122 + 52 =144 + 25 = 169
• So the total distance becomes = 13 km.

​Hence, the correct answer is "13 km".

Each daughter has the same number of brothers as she has sisters. This means, since there are D daughters, each daughter has D-1 sisters (because a girl cannot be her own sister), and each daughter also has as many brothers, which are S. So, D - 1 = S.

Next, look at the second condition. Each son has twice as many sisters as he has brothers. Thus, for the S sons, there are S-1 brothers (since a boy cannot be his own brother), and twice as many sisters, which are D. So, 2 × (S - 1) = D.

Now, the above gives us a system of two equations, which we can solve simultaneously to get the values for D and S.

Let's plug D = S + 1 from the first equation into the second one to solve for S:

2 × (S - 1) = S + 1

S = 3,

So, there are 3 sons in the family.

Hence, the correct answer is "Option (2)".

Family Chart:

Given:
Q is the mother of R.
P is the husband of Q.
S is the brother of R.

So, P is 'Father' of S.
Hence, the correct answer is "Option 1".

Seven students: R, S, T, U, V, W and X.

1) V scored more than W but less than U.

U > V > W

2) X scored more than S but less than R.

R > X > S

3) T scored more than U but less than S.

S > T > U

Combining all the statements:

R > X > S > T > U > V > W

W score the least marks in all the students.

Hence, the correct answer is "W".

The logic followed here is :-

"MELODY" is written as "LEMYDO".

and

"PURPLE" is written as "RUPELP".

Similarly,

"CLAUSE" will be written as :

Hence, the correct answer is "ALCESU".

The pattern followed here is:

Thus, the pattern which logically completes the series is ZUH 35.
Hence, the correct answer is Option (D).

The correct answer is option C.
Key Points
Analysis of Statements

• Statement i: In MS-Word 365, hanging indent sets the first line of a paragraph at the margin, and then indents each subsequent line of the paragraph.
  • A hanging indent is a type of paragraph formatting in which the first line of the paragraph is aligned with the left margin, while all subsequent lines are indented from the left margin.
  • This feature is commonly used in bibliographies and reference lists to make it easier to identify individual entries.
  • Hence, statement i is correct.
• Statement ii: MS - Word 365, the purpose of toggle case is to start each word in lower case and the rest in upper case.
  • The Toggle Case feature in MS Word changes each letter in a selected text to the opposite case; that is, it switches uppercase letters to lowercase and lowercase letters to uppercase.
  • It does not specifically start each word in lowercase and make the rest of the letters in uppercase.
  • Hence, statement ii is incorrect.
• Statement iii: In MS - Word 365, the popup dialog box 'Define New Bullet' under the 'Bullet' option in the 'Paragraph' group contains only two buttons, 'Symbol' and 'Picture'.
  • The 'Define New Bullet' dialog box in MS Word 365 indeed contains options to add a Symbol or a Picture as a bullet.
  • However, it also includes an option to define a Font for the bullet, so it contains more than just the two buttons mentioned.
  • Hence, statement iii is incorrect.

Additional Information

• Hanging Indent:
  • Uses: Commonly used in bibliographies and reference lists.
  • Features: Makes it easier to read and identify individual entries.
• Toggle Case:
  • Function: Changes each letter in the selected text to the opposite case.
  • Application: Useful for correcting text with incorrect case formatting.
• 'Define New Bullet' Dialog Box:
  • Options: Includes Symbol, Picture, and Font.
  • Purpose: Allows customization of bullet points in lists.

The correct answer is Formulas.

Key PointsFormulas

• Formulas in Excel are equations that perform calculations on values in your Excel worksheet.
• They can combine values, cell references, operators, and functions to produce a new value.
• Formulas are used to perform operations such as addition, multiplication, and comparison across cells.
• For example, the formula =A1+A2 adds the values in cells A1 and A2.
• Formulas can range from simple arithmetic operations to complex calculations involving nested functions.

• Functions are predefined formulas in Excel.
• They are designed to carry out specific calculations based on the arguments provided.
• Examples include SUM(), AVERAGE(), and VLOOKUP().
• While functions can be part of formulas, they are not in themselves equations that act on values in the worksheet but rather predefined operations that can be used within formulas.

• References in Excel are used to refer to cell(s) that contain the data you want to use in your formula.
• There are different types of references (relative, absolute, and mixed), and they determine how cell references change when a formula is copied to another cell.
• Although references are crucial elements within formulas for indicating which cells to calculate, they are not the calculations themselves.

• Constants are values that do not change when Excel recalculates a sheet.
• They can be directly entered into formulas.
• For example, in the formula =A1*10, the number 10 is a constant because it remains the same each time the formula is calculated.
• Constants can be numbers, text, or logical values (TRUE or FALSE) that are used in calculations, but unlike formulas, they do not perform calculations themselves.

The correct answer is F7
