HPCL Engineer Civil Full Test 1 - Mechanical Engineering MCQ

The correct answer is Option (2) i.e. goes.

Key Points

• The sentence is in simple present tense, indicated by the context of a habitual action (taking a walk every morning), making "goes" the correct verb form.
• "Goes" agrees with the third-person singular subject "She".
• Habitual actions, such as routines or habits, are typically described using simple present tense in English.

Therefore, the correct answer is- “She goes for a walk every morning to the park.”

The correct answer is "went".

Key Points

• The given sentence is a past event, meaning it already happened.
• Therefore, we need to use the past tense.
• "Went" is the simple past tense of the verb 'go', and it fits perfectly when referring to a completed past action or event.
• Therefore, 'went' is the most appropriate choice, making the sentence: "I went to the movie with some friends last night."

Hence, the correct answer is "Option 2".

Additional Information

• "Have gone" is the present perfect tense.
  • This tense is typically used to describe actions that have an effect on the current moment or actions that have just completed.
  • It's not suitable for this sentence which describes a past event that is completely finished with no connection to the present.
• "Am gone" receives the action but it indicates a state rather than a complete action, which makes it inappropriate for this sentence.
• "Am going" is a form of the present continuous tense used for plans or future arrangements, it's not suitable for describing past actions.

The correct answer is "from".

Key Points

• The sentence is based on the context of someone being restrained or prevented from making a quick decision.
• "Restrained" indicates controlled or held back from making a decision, and this action is accurately linked with the term 'from'.
• Generally, the verb "restrain" is followed by the preposition "from" when referring to preventing an event or action.
• The options "of”, "to”, "for”, and leaving the statement blank, fail to express the intended meaning of being restrained 'from' acting.
• Therefore, the correct answer is 'Option 4'.

Additional Information

• "Of": The preposition "of" indicates the relationship between a part and a whole or belonging to something.
• "To": "To" is used to express motion in the direction of or identify the person affected.
  • "Restrained to" is grammatically incorrect in this context.
• "For": "For" is used to express purpose or reason, but in the sentence, it doesn’t express the prevention of an action, which is necessary.

The correct answer is 'Option 1' i.e. 'Esteem'.

Key Points

• The word that is opposite in meaning to the given word "Ignominy" is: 'Esteem'
• "Ignominy" refers to public shame or disgrace(अपमान).
• "Esteem" is the opposite of "Ignominy". It refers to respect and admiration.(सम्मान).

Therefore, the correct answer is: 'Esteem'.

Additional Information

• Here's the explanation for the other options:
  • "Disrepute" - It means the state of being held in low regard by the public.(बदनामी).
  • "Stigma" - It refers to a mark of disgrace associated with a particular circumstance, quality, or person.(कलंक).
  • "Infamy" - It refers to the state of being well known for some bad quality or deed.(कुख्याति).

The correct answer is Option(2), i.e. "would have allocated"

Key Points

• The sentence structure implies a conditional past perfect scenario, which requires the use of "would have" followed by the past participle of the verb to express a hypothetical action in the past.
• The use of "had the team anticipated" sets the conditional and past context, necessitating the use of "would have allocated" to correctly complete the thought.

Therefore, the correct sentence is- "Had the team anticipated the complexity of the project from the onset, they would have allocated much greater resources to ensure its timely completion."

Additional Information

• Option 1 ("would allocate") is incorrect because it does not correctly use the past conditional form required by the sentence's setup.
• Option 3 ("had allocated") incorrectly suggests that the action was completed in the past, which does not fit the conditional nature of the sentence.
• Option 4 ("allocates") is incorrect because it presents the verb in present tense, which is inconsistent with the past conditional mood implied by the sentence.

• The subject of the sentence, 'Stonehenge', is singular, and it requires the use of 'has' instead of 'have'.
• In addition to the appropriate auxiliary verb 'has', the main verb 'capture' needs to be in the past participle form 'captured' to fit properly within the present perfect tense structure 'has captured'.
• The present perfect tense 'has captured' correctly implies an action that happened at an unspecified time before now, which fits the context of the sentence.

​Therefore, the correct answer is 'Option 3'.

Corrected Sentence: Stonehenge has captured the hearts of people from pre-historic times due to its unique structure.

• 'Have capture' (option 1) and 'No correction' (option 4) - Both of these options keep the grammatically incorrect form found in the original statement, either by maintaining the incorrect auxiliary verb 'have' with a singular subject or by not changing the base form of the verb 'capture'.
• 'Have captured' (option 2) - Although 'captured' is the correct form of the main verb to use here, the auxiliary verb 'have' does not agree in number with the singular subject 'Stonehenge', making this option incorrect as well.

The correct answer is 'The books are'.

Key Points

• The subject in the sentence "The books" is plural.
• A plural subject like "books" should be followed by a plural verb, which in this case is 'are'.
• The verb 'are' agrees with the plural subject, so the improved sentence should be: "The books are on the table."

Therefore, the correct answer is 'Option 2'.

Additional Information

• Option 1 ‘The book are' is incorrect because 'The book', being singular, should be followed by a singular verb 'is', not 'are'.
• Option 3 ‘The book is', although grammatically correct, changes the meaning of the sentence because it makes the subject 'book' singular, whereas the original sentence has a plural subject 'books'.

The correct answer is 'wasn't it'.

Key Points

• The sentence is asking a question about whether Ireland was part of the UK in the past.
• The question tag "wasn't it" is used to confirm or seek agreement on a statement that is in the past tense.

Therefore, the correct sentence is: 'Ireland was part of the UK, wasn't it?

Additional Information

• Option 1) "Isn't it" is the present tense of the auxiliary verb "be" (is/are). It is incorrect because the sentence is in the past tense.
• Option 3) "hasn't it" is the present perfect tense of the auxiliary verb "have" (has/have). It is incorrect because the sentence is simply asking a question about a past event, not about something that happened in the past and continues to the present.
• Option 4) "weren't it" is the past tense of the auxiliary verb "be" (was/were) used with the pronoun "it." It is incorrect because the subject of the sentence is "Ireland," not "it."

The correct answer is “Appetizing”.

Key Points

• Sumptuous: lavish or luxurious.(भव्य या विलासी)
  • Example- The sumptuous feast was fit for a king.
• Appetizing: appealing to the sense of taste.(स्वाद की अनुभूति के लिए आकर्षक)
  • Example- The appetizing aroma of the food made my mouth water.
• Hence, the option that is similar in meaning to the given word is 'Appetizing'.

Therefore, the correct answer is “option 2”.

Additional Information

• Unpalatable: not pleasant to the taste.(स्वाद के लिए सुखद नहीं)
• Bland: lacking flavor or taste.(स्वाद या स्वाद का अभाव)
• Nutritious: providing the nutrients necessary for growth and health.(विकास और स्वास्थ्य के लिए आवश्यक पोषक तत्व प्रदान करना)

Here the correct answer is Imprudence.

Key Points

• The correctly spelt word is "Imprudence".
• Imprudence means the quality of being unwise or indiscreet.
  • Example: His imprudence led to the loss of the entire investment.
• Thus, the correct answer is Option 2.

The correct answer is "dissuade"

Key Points

• INDUCE means to bring about, cause, or give rise to something. 
  • For example - More than 4,000 teachers were induced to take early retirement.
• Dissuade means to convince someone not to do something or to discourage them from a particular course of action.
  • For example - John's friends tried to dissuade him from quitting his stable job and starting his own business.

Therefore, the correct answer is Option no. 1.

Here the correct answer is Susceptible.

Key Points

• The word "immune" refers to having protection or resistance against something, such as diseases or infections. In the given context, it specifically refers to the immune system's ability to defend the body against foreign substances and pathogens.("प्रतिरक्षा")
  • Example sentence: Vaccines help to boost your immune system, making you less susceptible to certain diseases.
• Among the given options:
• "Susceptible" means vulnerable or prone to something. In the context of immunity, it is the opposite of being immune. If someone is susceptible to a disease, it means their immune system is not able to provide sufficient protection against it.(अतिसंवेदनशील)
• "Fragile" means delicate or easily broken. It does not convey the opposite meaning of "immune" in the context of the immune system attacking the body.(कमज़ोर)
• "Sick" means unwell or having an illness. It is not an antonym of "immune."(बीमार)
• "Sedentary" means characterized by or involving little physical activity. It does not convey the opposite meaning of "immune."(गतिहीन)
• Among the options, "susceptible" is the best antonym of "immune" as it denotes the lack of immunity or the ability to resist the attacks of the immune system. In the case of autoimmune diseases, the immune system mistakenly attacks the body, indicating a lack of immunity against one's own cells or tissues.

The correct answer is "Many historians argues that".

Key Points

• The error lies in the subject-verb agreement. "Historians" is a plural noun, so the verb "argues" should be "argue."
• The presence of "s" in "argues" indicates a singular subject, making it incorrect with the plural subject "historians."
• Correcting "argues" to "argue" aligns the verb with the plural subject.
• Such errors are common when the subject's plurality is not matched by the verb, leading to grammatical inconsistency.

Therefore, the correct answer is- Correct answer A.

The correct answer is "off".

Key Points

• The sentence is about someone interrupting or abruptly ending their speech.
• The term 'broke' in this context signifies a sudden stop or interruption.
• "Off" is used here to signify the immediate cessation of the action.
• In the context of a speech or conversation, "broke off" means to suddenly stop speaking.
• Consequently, "broke off" is the appropriate term to use here. It correctly conveys the abrupt interruption of the speech.
• The other options provided, such as "with", "apart", "in", and the blank option, don't correctly fit into the context of the sentence.
• Therefore, the correct answer is 'Option 1'.

Additional Information

• "With": The preposition "with" shows the relationship of an object with its surroundings or other related aspects.
  • However, it does not properly fit the context of abruptly ending a speech.
• "Apart": "Apart" signifies being separate or away.
  • Using "broke apart" in this context would indicate a physical disintegration, which is not correct here.
• "In": "In" shows the relation of an object with its surrounding environment, and in some cases, the initiation of an action.
  • It does not correctly denote the cessation of action, as indicated in the sentence.

Here the correct answer is Angryest.

Key Points

• The correct answer i.e. angryest is incorrectly spelled.
• Let's look at its correct spelling and meaning:-
  • Angriest - It is the superlative degree of angry. It means feeling or showing strong annoyance, displeasure, or hostility; full of anger. 
• Thus, the correct answer is Option 2.

The correct answer is Option (2) i.e. "wants".

Key Points

• Here "Each one" is the main subject which is singular.
• "Each one of the workers" implies each worker individually which requires a singular verb.
• "Wants" correctly agrees with the singular subject phrase.

Therefore, the correct answer is- "Each one of the workers wants a raise in salary from the coming month."

Additional Information

• Option (1) "are wanting" does not agree with the singular subject phrase.
• Option (3) "have wanted" does not correctly fit the singular subject in present tense.
• Option (4) "want" is plural and does not agree with the singular subject phrase.

The correct answer is "had stopped".

Key Points

• This sentence is using the past perfect tense, which is used to indicate that one action in the past happened before another action in the past.
• The structure of the past perfect tense is:
  • had + past participle (in this case, "stopped", which is the past participle of "stop").
• With the use of "by the time" in the sentence, it clearly suggests that one event (the rain stopping) had already finished before another event (reaching home) took place.

Therefore, the correct answer is "option 2".

Complete Sentence: "By the time we reached home, the rain had stopped."

Given:

Number of white balls = 5 Number of red balls = 4

Concept used:

The probability of an event occurring is given by the number of favorable outcomes divided by the total number of possible outcomes.

Calculation:

Total number of balls = Number of white balls + Number of red balls

= 5 + 4 = 9

Number of favorable outcomes (drawing a ball that is not red) = Number of white balls

= 5

Probability = Number of favorable outcomes / Total number of possible outcomes

= 5 / 9

Therefore, the probability that the ball drawn is not red is 5/9.

The correct option is: 2) 5/9

Calculation:

Let x, y, and z be the number of Rs. 50, Rs. 100, and Rs. 500 notes, respectively.

According to the question,

x + y + z = 32 and 50x + 100y + 500z = 5350.

First, let's eliminate z from the second equation by substituting z = 32 - x - y

⇒ 50x + 100y + 500(32 - x - y) = 5350

Simplify the equation:

50x + 100y + 16000 - 500x - 500y = 5350

⇒ -450x - 400y = -10650 (Divide by -50)

9x + 8y = 213

Now, we can find a solution by trial method:

x = 13, y = 12 → 9(13) + 8(12) = 213 (This solution works)

So, x = 13 and y = 12. Now, we can find z:

z = 32 - x - y = 32 - 13 - 12 = 7

∴ The correct answer is x=13 (Rs. 50 notes), y=12 (Rs. 100 notes), and z=7 (Rs. 500 notes).

Given:

An alloy of copper and nickel contains 60 % copper. The ratio of copper and nickel in the second alloy is 17 ∶ 4.

Calculation:

First alloy:

Copper = 60% and Nickel = 40%

Ratio: 60 : 40 = 3 : 2

Second alloy: Ratio = 17 : 4

The proportion of copper in the 1st alloy = 3/5

The proportion of copper in the 2nd alloy = 17/21

Let the ratio of the two alloys in the new mixture be m : n.

The total amount of copper in the new mixture = +

The total amount of nickel in the new mixture = +

According to the question,

+ : + =

⇒ : =

⇒ =

⇒ 63m + 85n = 168m + 80n

⇒ 105m = 5n

⇒ = =

∴ Option (1) is the correct answer.

Given:

A carton contains 5,00,000 tablets of medicine and 1200 packets of cotton

Calculation:

Each tablet weighing 30 mg = 30/1000000 kg = 3 × 10^-5 kg

Each cotton packet weighing 50 g = 50/1000 kg = 5 × 10^-2 kg

Then, the total weight of the contents of the carton

⇒ (500000 × 3 × 10^-5 + 1200 × 5 × 10^-2)

⇒ (15 + 60)

⇒ 75 kg

∴ The correct answer is 75 kg

Calculation:

Rahul has 3 cans of 25 L, so total volume of the cans = 25 × 3 × 1000 = 75000 ml

Now, he has to fill 750 ml bottles, total bottles can be filled = 75000/750 = 100

∴ The correct answer is 100

Given :

Radius of the top of the circular shape (r) = 20 CM.

Height of the cylinder (h) = 160 CM.

Formula used:

The outer surface area of the hemisphere = 2πr²

The curved surface area of the cylinder = 2πrh

where, r = Radius, and h = Height

Calculation:

The total surface area of ​​the bird bath pot equal to

Curved surface area of the cylinder + Inner surface area of the hemisphere

The curved surface area of ​​the bird bath pot

⇒ 2πr² + 2πrh

⇒ 2 × π × 202 + 2π × 20 × 160

⇒ 6400π + 800π = 7200π cm2

∴ The correct answer is 7200 π cm².

Calculation:

In the exam total questions = 120

Now, she didn't attempt 15 question, so her total attempts = (120 - 15) = 105

Here, 80% of her attempted questions were correct, so total correct questions = (105 × 80/100) = 84, incorrect attempt = 21

So, total marks obtained by Reena = (84 × 2) - 21 = 147

∴ The correct answer is 147

Given :

Spherical lead shots of radius 2.1 cm.

Rectangular lead piece of dimension 84 cm, 77 cm, 63 cm.

Formula used :

Volume of sphere = 4/3πr³

Volume of cuboid = l × b × h

Calculation :

According to question,

Let the number of spherical lead shots be n.

⇒ 84 × 77 × 63 = n × 4/3 × 22/7 × 2.1 × 2.1 × 2.1

⇒ 21 × 77 × 63= n × 1/3 × 22/7 × 21/10 × 21/10 × 21/10

⇒ 21 × 77 × 63 = n × 22 × 21/10 × 21/10 × 1/10

⇒ 77 × 63 = n × 22 × 21/1000

⇒ 7/2 × 63 = n × 21/1000

⇒ n = 7/2 × 3000

⇒ n = 7 × 1500

⇒ n = 10500

∴ The correct answer is 10500.

Given:

The inradius of the triangle = 5.5 cm

Perimeter = 36 cm

Formula used:

Semi perimeter of triangle (s) = a/2

Area of triangle = Inradius × S

Calculation:

According to the question,

Semi perimeter of triangle = (36/2) = 18 cm

Now,

Area of triangle = (5.5 × 18) cm2

⇒ 99 cm2

∴ The required area is 99 cm2.

Given :

SP = Rs.980

Loss =

Gain= 8%

Calculation :

By applying ratio method,

Loss = = 20/3% = 2/30

Gain = 8% = 8/100 = 2/25

Now,

SP = 28 = 980

⇒ 1 = 35

CP = 30 × 35 = 1050

Now,

CP = 25 = 1050

⇒ 1 = 42

SP = 27 × 42 = 1134

∴ The correct answer is 1134.

Calculation:

Let's assume a = 1, b = 2, c = 3, then all possible 3-digit numbers formed by a, b, c without repetition are,

123, 132, 213, 231, 312, and 321, so the sum of these numbers = 1332

Here, 1332 is a multiple of 37

∴ The correct answer is 37

Calculation:

Total principal = 25000 and total interest receive = 2031.25

So, all-over interest rate = 2031.25/25000 × 100 = 8.125%

So, the 1st part and 2nd part of the principal were lent out in the ratio 3 : 1

Now, the 2nd part of the money is = 25000 × = Rs. 6250

∴ The correct answer is Rs. 6,250

Given:

Mode of a series exceeds its median by 10

Concept used:

Mode = 3 Median - 2 Mean

Calculation:

Mode = Median + 10

Again,

Mode = 3 Median - 2 Mean

⇒ Median + 10 = 3 Median - 2 Mean

⇒ 10 = 3 Median - Median - 2 Mean

⇒ 10 = 2 Median - 2 Mean

⇒ 5 = Median - Mean

⇒ 5 + Mean = Median

So,

Mode = 5 + Mean + 10

⇒ Mean + 15

∴ Mode exceeds the mean by 15.
