((b))
around the corner
((c))

Show Answer

Answer: ((c))

against the clock

The correct answer is '3' i.e. against the clock .

Key Points

The phrase "against the clock" is a commonly used idiom that means working under time pressure or with urgency to meet a deadline.
In the given sentence, the phrase aligns perfectly with the context, as the team is described as working hard to finalize the report before the deadline.
Let’s evaluate the other options:
Option 1 - "under wraps": This phrase means keeping something secret or confidential, which doesn’t fit the context of the sentence.
Option 2 - "around the corner": This phrase refers to something that is about to happen soon, but it doesn’t describe the urgency of the team’s work.
Option 4 - "in high spirits": This phrase means being happy or cheerful, which doesn’t convey the sense of urgency described in the sentence.

Correct sentence: As the deadline approached, the team was working against the clock to finalize the report.

((a))
Fortunate
((b))
Lucky
((c))

((d))
Successful

Show Answer

Answer: ((c))

Unlucky

The correct answer is '3' i.e. Unlucky .

Key Points

The word "hapless" is used to describe someone or something that is unfortunate or unlucky.
Among the given options:
Fortunate means having good fortune or luck, which is the opposite of hapless.
Lucky also means having good fortune, which is not a synonym of hapless.
Unlucky directly matches the meaning of hapless, making it the correct synonym.
Successful indicates achieving success, which again is not related to the meaning of hapless.
Thus, the most appropriate synonym for "hapless" is Unlucky.

Correct Sentence: The synonym of "hapless" is unlucky.

Additional Information

Synonyms are words that have similar meanings. They help in enhancing vocabulary and improving sentence construction.
Antonyms are words that have opposite meanings. For example:
The antonym of hapless is fortunate or lucky.

Show Answer

Answer: ((c))

in stride

The correct answer is '3' i.e. in stride .

Key Points

The phrase "in stride" is an idiom used to describe a calm and composed reaction to a challenging or difficult situation.
In this context, the sentence mentions that the individual took the criticism positively and utilized it as a tool for self-improvement.

She used a hand saw to cut the plank in half.
((b))
We needed a power saw to cut through the thick branch.
((c))
I saw a beautiful sunset last night.
((d))
The lumberjack’s saw was very loud.

Show Answer

Answer: ((c))

I saw a beautiful sunset last night.

The correct answer is '3' i.e. I saw a beautiful sunset last night .

Key Points

The word "saw" in the sentence "He saw the car coming too late" is used as the past tense of the verb "see", which refers to the act of perceiving something with the eyes.
Option 3, "I saw a beautiful sunset last night," uses "saw" with the same meaning as perceiving something visually.
The other options (1, 2, and 4) use "saw" as a noun referring to a tool for cutting, which does not match the meaning of the word in the given sentence.

Correct sentence: "I saw a beautiful sunset last night".

Additional Information

Homonyms: Words like "saw" can have different meanings depending on the context. In this case:
As a verb: To perceive visually (e.g., "He saw the car").
As a noun: A tool used for cutting (e.g., "She used a hand saw").
Understanding context is essential to interpreting the correct meaning of a word in a sentence.

Read the following passage and answer the questions based on it:

Online purchasing, which combines unmatched ease with a distinct set of disadvantages, has completely changed how consumers behave. Accessibility is its main benefit; customers may explore and buy things from almost anywhere at any time, and there is frequently a greater selection than in physical stores. Important lures include competitive pricing, made possible by internet retailers' reduced overhead, and the simplicity of comparing prices from several providers. However, there are significant drawbacks to online shopping's virtual nature. Delivery-related discontent may result from the inability to personally inspect things before purchase. Concerns over shipping delays, unstated expenses, and the effects of packaging and transportation on the environment are becoming more widespread. Additionally, the individualised customer service experience may be weakened by a lack of human interaction.

What is the primary advantage of online purchasing according to the text?

((a))
It allows for in-person inspection of products
((b))
It provides easy access to a wider selection of items from anywhere at any time
((c))
It offers higher prices than physical stores
((d))
It eliminates the need for shipping

Show Answer

Answer: ((b))

It provides easy access to a wider selection of items from anywhere at any time

The correct answer is Option 2.

Key Points

The passage explicitly identifies the primary benefit in the second sentence: "Accessibility is its main benefit; customers may explore and buy things from almost anywhere at any time, and there is frequently a greater selection than in physical stores."
This captures the essence of convenience and variety that defines the modern e-commerce paradigm.
Why other options are incorrect:
Option 1: The text states the "inability to personally inspect things" is actually a drawback of the virtual nature of online shopping.
Option 3: The passage mentions "competitive pricing" (often lower) due to reduced overhead, not higher prices.
Option 4: The text notes that concerns over "shipping delays" are widespread, meaning shipping is very much a part of the process and not eliminated.

Therefore, the correct answer is 2.

Analytical Insight: For exams, watch out for "absolute" words like "eliminates" or "higher/lower." Authors usually provide a balanced view, and the correct answer will mirror the specific degree of benefit mentioned in the text.

Additional Information

Unmatched ease: Level of convenience that cannot be equaled by other methods.
Overhead: The regular and necessary costs of running a business, such as rent and utilities.
Discontent: A lack of satisfaction or happiness.
Virtual nature: Existing in a technological environment rather than a physical one.

What is one of the key benefits of online shopping in terms of pricing?

((a))
Higher prices due to store overhead costs
((b))
Competitive pricing due to lower overhead costs for online retailers
((c))
Fixed prices with no possibility of comparison
((d))
Prices that remain constant across all platforms

Show Answer

Answer: ((b))

Competitive pricing due to lower overhead costs for online retailers

The correct answer is Option 2.

Key Points

The passage identifies competitive pricing as an important "lure" (attraction) for online shoppers.
It explains the reason behind this: it is "made possible by internet retailers' reduced overhead." Since online stores don't have to pay for expensive physical storefronts or large in-person staff, they can pass those savings to the customer.
Why other options are incorrect:
Option 1: This is the opposite of what the text says. Physical stores have higher overhead, not online ones.
Option 3: The passage highlights the "simplicity of comparing prices," which contradicts the idea of fixed prices with no comparison.
Option 4: The text mentions the ability to compare prices from "several providers," implying that prices differ across platforms.

Therefore, the correct answer is 2.

Analytical Insight: In competitive exams, questions about "causality" (the reason something happens) are common. The text provides a clear cause (reduced overhead) for the effect (competitive pricing).

Additional Information

Lures: Things that tempt or attract a person to do something.
Overhead: General expenses of a business (rent, utilities, etc.) that are not directly tied to creating a product.
Competitive Pricing: Setting the price of a product or service based on what the competition is charging.
Virtual nature: Something that exists in code or online rather than in physical form.

What is a significant drawback of online shopping mentioned in the text?

((a))
Lack of variety in products
((b))
The inability to inspect products before purchasing
((c))
Higher prices for shipping
((d))
Faster delivery times than physical stores

Show Answer

Answer: ((b))

The inability to inspect products before purchasing

The correct answer is Option 2.

Key Points

The passage explicitly discusses the "drawbacks" resulting from the virtual nature of e-commerce.
It states: "Delivery-related discontent may result from the inability to personally inspect things before purchase." This is a primary disadvantage because the consumer cannot verify the quality, size, or feel of a product until it arrives.
Why other options are incorrect:
Option 1: The text says there is frequently a "greater selection" online, not a lack of variety.
Option 3: While the text mentions "unstated expenses" and environmental "effects of transportation," it does not explicitly state that shipping prices are higher than other costs; it emphasizes the uncertainty and delays.
Option 4: "Faster delivery times" would be an advantage, not a drawback. Furthermore, the text mentions concerns over "shipping delays."

Therefore, the correct answer is 2.

Analytical Insight: In exams, questions about "drawbacks" often test your ability to distinguish between a factual disadvantage mentioned in the text and a general opinion. While shipping costs (Option 3) can be a drawback in real life, the text specifically emphasizes the inability to inspect items.

Additional Information

Discontent: Dissatisfaction with one's circumstances.
Virtual: Existing or occurring on computers or on the internet.
Unstated expenses: Hidden costs that are not clearly mentioned upfront (e.g., hidden taxes or handling fees).
Overhead: The regular costs of running a business, such as rent and insurance.

What are some growing concerns related to the environmental impact of online shopping?

((a))
Increased store visits
((b))
Concerns over shipping delays
((c))
Higher fuel consumption from physical stores
((d))
Limited product availability

Show Answer

Answer: ((b))

Concerns over shipping delays

The correct answer is Option 2.

Key Points

The passage groups environmental concerns together with other logistics-related issues. It states: "Concerns over shipping delays, unstated expenses, and the effects of packaging and transportation on the environment are becoming more widespread."
While "shipping delays" are primarily a logistical frustration, the text places them in the same list of growing concerns that include the environmental effects of packaging and transportation.
Why other options are incorrect:
Option 1: Online shopping generally reduces store visits; it does not increase them.
Option 3: The passage focuses on the environmental impact of packaging and transportation for online orders, not fuel consumption of physical stores.
Option 4: The text mentions that online shopping offers a "greater selection," which is the opposite of limited availability.

Therefore, the correct answer is 2.

Analytical Insight: In competitive exams, questions often ask you to identify a group of items mentioned together in the text. Even if "shipping delays" doesn't sound like an "environmental" issue, it is part of the specific list provided by the author regarding modern widespread concerns.

Additional Information

Unstated expenses: Hidden costs like taxes or convenience fees not shown in the initial price.
Discontent: Dissatisfaction or lack of contentment.
Overhead: The ongoing costs of operating a business (rent, utilities, etc.).
Individualised: Tailored to the specific needs or preferences of a person.

What aspect of the customer experience may be weakened by online shopping?

((a))
The ability to compare prices easily
((b))
Personalized customer service due to lack of human interaction
((c))
The variety of products available
((d))
Convenience of purchasing from anywhere

Show Answer

Answer: ((b))

Personalized customer service due to lack of human interaction

The correct answer is Option 2.

Key Points

The passage concludes by discussing the social/service aspect of e-commerce. It states: "Additionally, the individualised customer service experience may be weakened by a lack of human interaction."
In physical stores, customers often benefit from immediate, face-to-face assistance. Online shopping, while efficient, often replaces this with automated systems or delayed digital communication, which can feel less personal.
Why other options are incorrect:
Option 1: The text describes the "simplicity of comparing prices" as an "important lure" (an advantage), not a weakness.
Option 3: The passage notes there is "frequently a greater selection" online, meaning variety is a strength.
Option 4: Accessibility and the ability to buy from anywhere are listed as the "main benefit" of online purchasing.

Therefore, the correct answer is 2.

Analytical Insight: In exams, questions about "weaknesses" or "negatives" are often placed at the end of the passage. Look for transition words like "However," "Additionally," or "Conversely" to find these shifts in focus.

Additional Information

Individualised: Tailored to satisfy the specific requirements of an individual.
Lures: Qualities that attract or tempt one to do something.
Overhead: Business costs not directly related to the production of goods (e.g., rent, utilities).
Unmatched ease: A level of convenience that is superior to all others.

Very close and loyal

The correct answer is '1' i.e. Very close and loyal .

Statement: Advancements in surveillance technology have improved national security and crime prevention. However, concerns about mass surveillance and privacy violations have sparked debates on ethical boundaries and government overreach. Critics demand transparent policies and public oversight.

Conclusions:

I. Surveillance technology has both benefits and risks.

II. Public oversight and clear policies are needed to balance privacy and security.

III. Surveillance should be completely banned to protect individual freedom.

Which conclusion necessarily follows?

((a))
Only I follows
((b))
I and II follow
((c))
Only III follows
((d))
All follow

Show Answer

I and II follow

Analysis of Conclusions:

Conclusion I: Surveillance technology has both benefits and risks.

The statement mentions improvement in security (benefit) and privacy concerns (risk). Therefore, this conclusion follows.

Conclusion II: Public oversight and clear policies are needed to balance privacy and security.

The statement clearly says critics demand transparent policies and public oversight. Hence, this conclusion follows.

Conclusion III: Surveillance should be completely banned to protect individual freedom.

The statement only mentions concerns and demand for oversight, not a complete ban. Hence, this conclusion does not follow.

Hence, the correct answer is: Only Conclusions I and II follow.

Situation: A student has only 3 days left before an exam. She hasn't completed half the syllabus. What's the best strategy?

((a))
Watch motivational videos to calm nerves
((b))
Sleep less and cover all topics
((c))
Focus on high-weightage and familiar topics
((d))
Give up and skip the exam

Show Answer

Answer: ((c))

Focus on high-weightage and familiar topics

Situation:

A student has only 3 days left before an exam and half the syllabus is still incomplete.

Analysis of Options:

Watch motivational videos to calm nerves

This may reduce stress, but it does not directly help in completing the syllabus. Hence, it is not the most practical strategy.

Sleep less and cover all topics

Reducing sleep can harm concentration and efficiency, which may negatively affect exam performance.

Focus on high-weightage and familiar topics

This is a practical and effective strategy when time is limited. Prioritizing important and known topics can maximize marks within the available time.

Give up and skip the exam

This is not a reasonable response because the student still has time to prepare.

Hence, the correct answer is Focus on high-weightage and familiar topics.

Offer to help them prioritize tasks and suggest they talk to HR or supervisor

This response shows empathy, support, and professionalism while guiding them toward the proper authority who can help.

Tell them to leave work at home

This response is insensitive and does not provide any support.

Ignore since it's not your concern

Ignoring the situation shows a lack of teamwork and empathy.

Hence, the correct answer is 2) Offer to help them prioritize tasks and suggest they talk to HR or supervisor.

In a line of 40 children, Sita is 15^th from the beginning and Rita is 18^th from the end. How many children are there between Sita and Rita?

((a))
6
((b))
7
((c))
8
((d))
0

Show Answer

Answer: ((b))

Given:

Total number of children = 40

Position of Sita from the beginning = 15

Position of Rita from the end = 18

Formula Used:

Position from beginning = Total number − Position from end + 1

Children between two persons = Difference of positions − 1

Calculation:

Position of Rita from the beginning = 40 − 18 + 1 = 23

Position of Sita from the beginning = 15

Children between them = 23 − 15 − 1

= 8 − 1

= 7

Hence, the correct answer is 7.

Hence, the correct answer is 17th.

In each question below is given a statement followed by two courses of action numbered I and II. You have to assume everything in the statement to be true and on the basis of the information given in the statement, decide which of the suggested courses of action logically follow(s) for pursuing.

Statement : A high number of accidents are occurring at a railway crossing due to lack of proper signaling systems.

Course of action I : Install automated signaling systems at the crossing immediately.

Course of action II : Ban train services on that route

((a))
Only I follows
((b))
Only II follows
((c))
Both follow
((d))
Either I or II follows

Show Answer

Answer: ((a))

Only I follows

Analysis of Courses of Action:

Course of Action I: Install automated signaling systems at the crossing immediately.

This directly addresses the problem mentioned in the statement (lack of proper signaling). Hence, this course of action logically follows.

Course of Action II: Ban train services on that route.

This is an extreme step and does not logically solve the core problem. The issue can be resolved by improving the signaling system.

Hence, the correct answer is: Only Course of Action I follows.

Each question given below consists of a statement, followed by two arguments numbered I and II. You have to decide which of the arguments is a 'strong' argument and which is a 'weak' argument.

Statement : Should voting be made compulsory?

Argument I : Yes, it ensures better representation

Argument II : No, people should have freedom of choice.

((a))
Only I is strong
((b))
Only II is strong
((c))
Both I and II are strong
((d))
Neither I nor II is strong

Show Answer

Answer: ((c))

Both I and II are strong

Analysis of Arguments:

Argument I: Yes, it ensures better representation.

If voting is compulsory, more citizens will participate in elections, which can lead to broader and more representative results. Hence, this is a strong argument.

Argument II: No, people should have freedom of choice.

In a democratic system, individuals should have the freedom to decide whether to vote or not. Hence, this is also a strong argument.

Hence, the correct answer is: Both Argument I and Argument II are strong.

Investigate by collecting evidence from both sides
((b))
Ignore to avoid conflict
((c))
Promote the claimant to appease
((d))
Fire the colleague immediately

Show Answer

Answer: ((a))

Investigate by collecting evidence from both sides

Analysis of Options:

Investigate by collecting evidence from both sides

This is a fair and logical approach because HR should first understand the facts before taking any action.

Ignore to avoid conflict

Ignoring the issue may worsen workplace trust and morale.

Promote the claimant to appease

Promotion without proper investigation is not a justified solution.

Fire the colleague immediately

Taking such a drastic action without investigation is unfair.

Hence, the correct answer is 1) Investigate by collecting evidence from both sides.

Rs. 24,582
((c))
Rs. 30,000
((d))
Rs. 35,789

Show Answer

Answer: ((b))

Rs. 24,582

Given:

A capital = 80000

B capital = 60000

C capital = 40000

B increases capital by 25% after 6 months

C decreases capital by 10% after 6 months

Total profit = 120000

Formula Used:

Profit share ∝ Capital × Time

Calculation:

⇒ A investment for 12 months = 80000 × 12

⇒ A = 960000

⇒ B investment for first 6 months = 60000 × 6

⇒ B investment for next 6 months = (60000 × 125 ÷ 100) × 6

⇒ B = 360000 + 450000

⇒ B = 810000

⇒ C investment for first 6 months = 40000 × 6

⇒ C investment for next 6 months = (40000 × 90 ÷ 100) × 6

⇒ C = 240000 + 216000

⇒ C = 456000

⇒ Ratio A : B : C = 960000 : 810000 : 456000

⇒ Ratio = 320 : 270 : 152

⇒ Total ratio = 320 + 270 + 152

⇒ Total ratio = 742

⇒ C share = 120000 × 152 ÷ 742

⇒ C share = 18240000 ÷ 742

⇒ C share ≈ 24582.21

∴ The correct answer is ₹24582.

Given:

sin A = 7 ÷ 25

cos B = 24 ÷ 25

Formula Used:

sin²θ + cos²θ = 1

sin A cos B + cos A sin B = sin(A + B)

Calculation:

⇒ cos A = √(1 − (7 ÷ 25)²)

⇒ cos A = √(1 − 49 ÷ 625)

⇒ cos A = √(576 ÷ 625)

⇒ cos A = 24 ÷ 25

⇒ sin B = √(1 − (24 ÷ 25)²)

⇒ sin B = √(1 − 576 ÷ 625)

⇒ sin B = √(49 ÷ 625)

⇒ sin B = 7 ÷ 25

⇒ sin A cos B + cos A sin B

⇒ (7 ÷ 25 × 24 ÷ 25) + (24 ÷ 25 × 7 ÷ 25)

⇒ 168 ÷ 625 + 168 ÷ 625

⇒ 336 ÷ 625

((a))
₹100 profit
((b))
₹100 loss
((c))
₹200 profit
((d))
₹200 loss

Show Answer

Answer: ((a))

₹100 profit

Given:

First quantity = 50 kg

Cost price of first variety = 50 per kg

Second quantity = 30 kg

Cost price of second variety = 60 per kg

Selling price = 55 per kg

Formula Used:

Total cost price = Sum of (Quantity × Cost price)

Total selling price = Total quantity × Selling price per kg

Profit or Loss = Total selling price − Total cost price

Calculation:

⇒ Cost of first variety = 50 × 50

⇒ Cost = 2500

⇒ Cost of second variety = 30 × 60

⇒ Cost = 1800

⇒ Total cost price = 2500 + 1800

⇒ Total cost price = 4300

⇒ Total quantity = 50 + 30

⇒ Total quantity = 80 kg

⇒ Total selling price = 80 × 55

⇒ Total selling price = 4400

⇒ Profit = 4400 − 4300

⇒ Profit = 100

∴ The correct answer is Profit of ₹100.

Two numbers are respectively 20% less and 30% more than a third number. What is the ratio of the two numbers?

((a))
8:13
((b))
2:3
((c))
4:5
((d))
7:9

Show Answer

Answer: ((a))

8:13

Shortcut Trick

Assume the third number is 100.

The first number (20% less than 100) = 80.

The second number (30% more than 100) = 130.

The required ratio = 80 : 130 = 8 : 13.

∴ The correct answer is 8:13.

Alternate Method

Given:

Let the third number be x.

First number = x − (20/100) × x

Second number = x + (30/100) × x

Calculations:

⇒ First number = 0.8x

⇒ Second number = 1.3x

⇒ Ratio = First number : Second number

⇒ Ratio = 0.8x : 1.3x

⇒ Ratio = 8 : 13

∴ The correct answer is 8:13.

Additional Information

Percentage to Fraction Conversion

To simplify calculations, convert percentages to fractions: 20% = 1/5 and 30% = 3/10. If the third number is 1, the first is 1 − 1/5 = 4/5 and the second is 1 + 3/10 = 13/10.

Base Value Selection

In problems where two values are compared to a common third value, always assume the third value to be 100 or a multiple of the denominators to avoid decimal calculations.

Ratio Properties

The ratio a : b is the same as ka : kb for any non-zero constant k. Multiplying 0.8 : 1.3 by 10 removes the decimal to give 8 : 13.

48

Show Answer

Answer: ((c))

Shortcut Trick

Net change in total sum = (4 × 5) + (4 × (−3)) = 20 − 12 = +8

Net change in average = Total change ÷ Total numbers = 8 ÷ 8 = +1

New Average = Old Average + Change = 45 + 1 = 46

∴ The correct answer is 46.

Alternate Method

Given:

Total numbers = 8

Original Average = 45

Formula Used:

Total Sum = Average × Total Numbers

New Average = New Total Sum ÷ Total Numbers

Calculations:

⇒ Original Sum of 8 numbers = 8 × 45 = 360

⇒ Increase in first 4 numbers = 4 × 5 = 20

⇒ Decrease in last 4 numbers = 4 × 3 = 12

⇒ New Total Sum = 360 + 20 − 12 = 368

⇒ New Average = 368 ÷ 8 = 46

∴ The correct answer is 46.

Additional Information

Basic Average Property

If a constant 'k' is added to or subtracted from every number in a set, the new average increases or decreases by 'k'.

Weighted Average

When two or more groups are combined, the new average is calculated as A_avg = (n₁a₁ + n₂a₂) ÷ (n₁ + n₂).

Sum Property

The total sum of observations is always the product of the average and the total number of observations (Sum = Avg × n).

Answer: ((d))

54,000

Given:

Initial population = 40000

First year increase = 20%

Second year decrease = 10%

Third year increase = 25%

Formula Used:

New value after increase = Original value × (1 + Percentage ÷ 100)

New value after decrease = Original value × (1 − Percentage ÷ 100)

Calculation:

⇒ Population after first year = 40000 × (1 + 20 ÷ 100)

⇒ Population = 40000 × 1.20

⇒ Population = 48000

⇒ Population after second year = 48000 × (1 − 10 ÷ 100)

⇒ Population = 48000 × 0.90

⇒ Population = 43200

⇒ Population after third year = 43200 × (1 + 25 ÷ 100)

⇒ Population = 43200 × 1.25

⇒ Population = 54000

∴ The correct answer is 54000.

Show Answer

Answer: ((b))

11:30 AM

Given:

Thief's speed = 20 km/h

Police car's speed = 30 km/h

Thief starts at 10:00 AM

Police car starts at 10:30 AM

Formula Used:

Distance = Speed × Time

Relative speed = Speed of police car - Speed of thief

Time = Distance ÷ Relative speed

Calculation:

⇒ Thief's head start time = 10:30 AM - 10:00 AM = 0.5 hours

⇒ Distance covered by thief in 0.5 hours = 20 × 0.5 = 10 km

⇒ Relative speed = 30 - 20 = 10 km/h

⇒ Time taken by police car to catch thief = 10 ÷ 10 = 1 hour

⇒ Police car catches thief at 10:30 AM + 1 hour = 11:30 AM

∴ The correct answer is 11:30 AM.

A can do a work in 15 days, B in 30 days. They start together but A leaves after 5 days. In how many more days will B complete the remaining work?

((a))
15 days
((b))
6 days
((c))
7 days
((d))
8 days

Show Answer

Answer: ((a))

15 days

Shortcut Trick

Total work = LCM(15, 30) = 30 units.

Efficiency of A = 2 and B = 1 (Combined = 3 units/day).

Work done by (A+B) in 5 days = 3 × 5 = 15 units.

Remaining work = 30 − 15 = 15 units.

Time for B to finish remaining work = 15 ÷ 1 = 15 days.

∴ The correct answer is 15 days.

Alternate Method

Given: Time taken by A = 15 days and B = 30 days. They work together for 5 days.

Formula: Total Work = LCM of individual time; Efficiency = Total Work ÷ Time taken.

Person	Days	Total Work	Efficiency
A	15	30 (LCM)	30 ÷ 15 = 2
B	30	30 ÷ 30 = 1

⇒ Combined efficiency of A + B = 2 + 1 = 3 units/day.

⇒ Work done by A and B together in 5 days = 5 × 3 = 15 units.

⇒ Remaining work = Total Work − Completed Work = 30 − 15 = 15 units.

⇒ Time taken by B to complete the remaining work = 15 ÷ 1 = 15 days.

∴ The correct answer is 15 days.

Additional Information

Relation between Time and Efficiency

Time and efficiency are inversely proportional to each other. If the ratio of time taken is x:y, then the ratio of efficiency is y:x.

Pipes and Cisterns

The same LCM method applies to pipes, where filling pipes have positive efficiency and outlet/leakage pipes have negative efficiency.

Work and Wages

Wages are distributed among workers based on the ratio of the actual work done by each person.

Show Answer

Answer: ((a))

₹1500

Given:

Selling price = 1800

Profit = 20%

Formula Used:

Selling price = Cost price × (1 + Profit ÷ 100)

Calculation:

⇒ 1800 = Cost price × (1 + 20 ÷ 100)

⇒ 1800 = Cost price × 1.20

⇒ Cost price = 1800 ÷ 1.20

⇒ Cost price = 1500

∴ The correct answer is 1500.

A sum of money doubles itself in 8 years at a certain rate of simple interest. In how many years will it become five times itself at the same rate?

((a))
16 years
((b))
24 years
((c))
32 years
((d))
40 years

Show Answer

Answer: ((c))

32 years

Shortcut Trick

For Simple Interest, use the ratio: (n₁ − 1) / T₁ = (n₂ − 1) / T₂

Here, n₁ = 2 (doubles), T₁ = 8 years, and n₂ = 5 (five times).

(2 − 1) / 8 = (5 − 1) / T₂

1 / 8 = 4 / T₂ ⇒ T₂ = 4 × 8 = 32 years.

∴ The correct answer is 32 years.

Alternate Method

Given: Sum doubles (A = 2P) in 8 years.

Formula: Simple Interest (SI) = (P × R × T) / 100

⇒ Case 1: SI₁ = Amount − Principal = 2P − P = P

⇒ P = (P × R × 8) / 100 ⇒ R = 100 / 8 = 12.5%

⇒ Case 2: New Amount = 5P, so SI₂ = 5P − P = 4P

⇒ 4P = (P × 12.5 × T₂) / 100

⇒ 4 = (12.5 × T₂) / 100

⇒ T₂ = (4 × 100) / 12.5 = 400 / 12.5 = 32 years

∴ The correct answer is 32 years.

Additional Information

Simple Interest Multiplier Rule

If a sum becomes n times in T years, the rate R is given by R = [(n − 1) × 100] / T.

Constant Interest Property

((a))
10%
((b))
15%
((c))
5%
((d))
12%

Show Answer

Answer: ((a))

10%

Shortcut Trick

Investment Scheme A : Scheme B = 150 : 100 = 3 : 2

Given Scheme A = ₹2,400 ⇒ 3 units = ₹2,400, so 2 units (Scheme B) = ₹1,600

Total SI = (2,400 × 4 × r/100) + (1,600 × 5 × (r+2)/100) = 1,920

96r + 80r + 160 = 1,920 ⇒ 176r = 1,760 ⇒ r = 10%

∴ The correct answer is 10%.

Alternate Method

Given:

Investment in Scheme A (P_A) = ₹2,400

Time for Scheme A (T_A) = 4 years, Rate (R_A) = r%

Investment in Scheme B (P_B): P_A is 50% more than P_B ⇒ 2,400 = 1.5 × P_B

Time for Scheme B (T_B) = 5 years, Rate (R_B) = (r + 2)%

Total Simple Interest = ₹1,920

Formula Used: Simple Interest (SI) = (P × R × T) / 100

⇒ P_B = 2,400 / 1.5 = ₹1,600

⇒ SI_A = (2,400 × r × 4) / 100 = 96r

⇒ SI_B = (1,600 × (r + 2) × 5) / 100 = 80(r + 2) = 80r + 160

⇒ Total SI = SI_A + SI_B = 1,920

⇒ 96r + 80r + 160 = 1,920

⇒ 176r = 1,920 − 160

⇒ 176r = 1,760

⇒ r = 1,760 / 176 = 10

∴ The correct answer is 10%.

Additional Information

Simple Interest (SI)

The interest is calculated only on the initial Principal amount for the entire duration. Formula: SI = (P × R × T) / 100.

Amount in SI

The total money accumulated after the time period. Amount = Principal + Simple Interest.

Effective Interest Rate

For Simple Interest, the total effective rate over T years is simply (R × T)% of the principal.

A shopkeeper mixes 4 liters of a milk solution containing 25% fat with 6 liters of another milk solution containing 40% fat. What is the fat percentage in the final mixture?

((a))
30%
((b))
32%
((c))
34%
((d))
35%

Show Answer

Answer: ((c))

34%

Shortcut Trick

Ratio of the milk solutions = 4 : 6 = 2 : 3.

Net fat percentage = [(Ratio₁ × Fat₁) + (Ratio₂ × Fat₂)] ÷ Total Ratio parts.

Net fat percentage = [(2 × 25) + (3 × 40)] ÷ (2 + 3) = (50 + 120) ÷ 5 = 170 ÷ 5 = 34%.

∴ The correct answer is 34%.

Alternate Method

Given:

Quantity of first solution = 4 liters with 25% fat.

Quantity of second solution = 6 liters with 40% fat.

Formula Used:

Total Fat Content = (Quantity₁ × Fat %₁) + (Quantity₂ × Fat %₂)

Final Fat Percentage = (Total Fat Content ÷ Total Quantity) × 100

⇒ Fat in 4 liters of solution = 4 × (25 ÷ 100) = 1.0 liter

⇒ Fat in 6 liters of solution = 6 × (40 ÷ 100) = 2.4 liters

⇒ Total quantity of final mixture = 4 + 6 = 10 liters

⇒ Total fat in final mixture = 1.0 + 2.4 = 3.4 liters

⇒ Final fat percentage = (3.4 ÷ 10) × 100 = 34%

∴ The correct answer is 34%.

Additional Information

Rule of Alligation

It states that the ratio of the quantities is the inverse ratio of the differences from the mean: (Quantity₁ ÷ Quantity₂) = (C₂ − M) ÷ (M − C₁), where M is the mean value.

Weighted Average

The combined average of two or more groups can be calculated using A_avg = (n₁a₁ + n₂a₂ + ...) ÷ (n₁ + n₂ + ...).

Newton's third law of motion states that _______.

((a))
For every action, there is an equal and opposite reaction
((b))
For every action, the reaction is opposite but greater in magnitude
((c))
The rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force
((d))
An object in motion remains in motion unless acted upon by a force

Show Answer

Answer: ((a))

For every action, there is an equal and opposite reaction

The correct answer is For every action, there is an equal and opposite reaction.

Key Points

Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. This implies that forces always occur in pairs, known as action-reaction force pairs.
When an object exerts a force on another object, the second object exerts an equal force in the opposite direction on the first object. For example: When you push against a wall, the wall pushes back with an equal force.
The forces in the action-reaction pair act on different objects and never cancel each other. This is because they are equal in magnitude but opposite in direction.
This principle applies to all interactions, such as gravitational, electromagnetic, and contact forces. It is a fundamental concept in classical mechanics.
This law is responsible for phenomena like the recoil of a gun when fired or the propulsion of a rocket. Hence, the correct statement is provided in option 1.

Additional Information

Explanation of Incorrect Options:
Option 2: "For every action, the reaction is opposite but greater in magnitude" is incorrect because Newton's Third Law specifically states the reaction force is equal in magnitude to the action force.
Option 3: "The rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force" refers to Newton's Second Law of Motion, not the third law.
Option 4: "An object in motion remains in motion unless acted upon by a force" refers to Newton's First Law of Motion, also known as the Law of Inertia.
Applications of Newton's Third Law:
Rocket Propulsion: A rocket expels gas downwards, and as a reaction, it is propelled upwards.
Swimming: A swimmer pushes water backward with their hands and legs, and the water pushes them forward.
Walking: When we push the ground backward with our feet, the ground pushes us forward.
Historical Context: Newton's laws of motion were formulated by Sir Isaac Newton in 1687 and were published in his book, Philosophiæ Naturalis Principia Mathematica.
Real-World Examples:
Recoil of a Gun: When a bullet is fired, the gun experiences a backward force (recoil) due to the forward force exerted on the bullet.
Bird Flight: Birds push air downward with their wings, and the air pushes them upward, allowing them to fly.

Important Points

Newton's Laws of Motion:
First Law: Describes inertia, stating that an object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an external force.
Second Law: Establishes the relationship between force, mass, and acceleration. It is mathematically expressed as F = ma.
Third Law: States that for every action, there is an equal and opposite reaction.
Conservation of Momentum: Newton's Third Law is closely related to the principle of conservation of momentum, which states that the total momentum in a closed system remains constant.
Universal Applicability: Newton's Third Law is universally applicable and forms the basis for various engineering and physical sciences, including aerospace, mechanics, and robotics.

An Indian state can be divided or its boundary altered by which of the following?

((a))
The State Legislature
((b))
Parliament
((c))
President
((d))
Supreme Court

Show Answer

Answer: ((b))

Parliament

The correct answer is Parliament.

Key Points

Article 3 of the Constitution of India grants the Parliament of India the exclusive authority to create new states, alter state boundaries, or change the name of an existing state.
The process involves introducing a bill in Parliament for the reorganization or alteration of states. The President's recommendation is mandatory before introducing such a bill. The state legislature's opinion is sought but does not carry binding authority.
Parliament can reorganize states by separating territories, merging existing states, or annexing territories to a particular state. This ensures flexibility in addressing administrative needs or sociopolitical changes.
Historical examples: The formation of states like Jharkhand (2000), Telangana (2014), and Chhattisgarh (2000) showcases Parliament's pivotal role in state reorganization.
The Supreme Court does not play a direct role in altering state boundaries. Similarly, the State Legislature lacks authority to independently reorganize or create new states. Hence, the correct answer is Parliament.

Article 3 of the Constitution:
Article 3 provides a framework for the reorganization of states. It allows Parliament to create new states, alter boundaries, and rename states based on administrative, geographical, or socio-political needs.
Before introducing a bill for state reorganization, it is necessary to obtain the President's recommendation. The opinion of the concerned state's legislature is sought, but Parliament has the final authority.
Historical Examples of State Reorganization:
1956: The States Reorganization Act was passed, creating states based on linguistic lines such as Gujarat, Maharashtra, Karnataka, and Andhra Pradesh.
2000: Three new states — Jharkhand, Chhattisgarh, and Uttarakhand — were formed to address specific sociopolitical demands.
2014: Telangana was carved out of Andhra Pradesh to meet long-standing demands for statehood.
Role of the President:
The President of India must recommend a bill for state reorganization before its introduction in Parliament.
The President refers the bill to the concerned state legislature for its opinion, but Parliament holds the final decision-making authority.
State Legislature and Supreme Court:
The State Legislature can provide its opinion on reorganization but lacks authority to independently alter state boundaries or create new states.
The Supreme Court does not have direct jurisdiction to reorganize states but can review disputes arising from state reorganization acts.

Important Points

Constitutional Provisions:
Article 2: Parliament can admit new territories into the Union of India.
Article 4: Any law under Articles 2 and 3 is not considered an amendment to the Constitution under Article 368.

What is the process called when organisms acquire oxygen from outside the body to break down food sources?

((a))
Respiration
((b))
Digestion
((c))
Photosynthesis
((d))
Fermentation

Show Answer

Answer: ((a))

Respiration

The correct answer is Respiration.

Key Points

Respiration is the biological process by which organisms acquire oxygen from their surroundings to break down food molecules and release energy. This energy is used for various cellular functions.
Oxygen is essential for the process of aerobic respiration, where glucose or other organic molecules are oxidized to produce ATP (Adenosine Triphosphate), the energy currency of cells.
During respiration, the breakdown of food molecules (mainly glucose) occurs in the mitochondria of cells, releasing carbon dioxide and water as by-products.
Respiration can be categorized into aerobic respiration (requires oxygen) and anaerobic respiration (occurs without oxygen).
This process is crucial for the survival of most living organisms, including humans, animals, and plants, as it provides the necessary energy for maintaining life processes.
Hence, the correct answer is Respiration.

Additional Information

Aerobic Respiration:
Occurs in the presence of oxygen.
The complete breakdown of glucose into carbon dioxide and water releases a significant amount of energy.
The chemical equation is: C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy.
This type of respiration is more efficient and produces approximately 36-38 ATP molecules per glucose molecule.
Anaerobic Respiration:
Occurs in the absence of oxygen.
It involves the partial breakdown of glucose into products like lactic acid (in animals) or ethanol and carbon dioxide (in yeast).
This process produces less energy, yielding only 2 ATP molecules per glucose molecule.
Anaerobic respiration is common in microorganisms and occurs in human muscles during intense exercise when oxygen supply is limited.
Digestion:
Digestion is the process of breaking down food into simpler molecules that can be absorbed by the body. It does not involve oxygen acquisition or energy production.
It primarily occurs in the digestive system and involves enzymes such as amylase, lipase, and protease.
Hence, digestion is not related to the process mentioned in the question.
Photosynthesis:
Photosynthesis is a process used by plants, algae, and some bacteria to convert light energy into chemical energy stored in glucose.
It occurs in the presence of sunlight, carbon dioxide, and water, producing oxygen as a by-product.
The chemical equation is: 6CO2 + 6H2O + Light Energy → C6H12O6 + 6O2.
Hence, photosynthesis is not the correct answer.
Fermentation:
Fermentation is a type of anaerobic respiration that occurs in yeast and some bacteria, producing ethanol and carbon dioxide.
It is used in industries for making alcoholic beverages and bread.
Since fermentation does not involve acquiring oxygen from outside, it is not the correct answer.

Important Points

Cellular Respiration: Cellular respiration consists of three main stages: Glycolysis, Krebs Cycle, and Electron Transport Chain, where most ATP is generated.
Energy Utilization: The energy produced during respiration is used for essential processes like growth, reproduction, repair, and maintaining homeostasis in organisms.
Oxygen Role: Oxygen acts as the final electron acceptor in aerobic respiration, enabling the release of large amounts of energy stored in glucose.
Comparison: Aerobic respiration is more efficient than anaerobic respiration, as it produces more ATP per molecule of glucose.
Mitochondria: Known as the powerhouse of the cell, mitochondria are the site of aerobic respiration and ATP synthesis in eukaryotic cells.
