Therefore, the correct answer is - Option 3 "is".

• 'Are' is incorrect as it is used with plural nouns.
• 'Were' is also incorrect as it is the past tense of 'are' and doesn't fit in the context of this sentence.
• 'Have' is usually used to indicate possession or to form perfect tenses.

The correct answer is "reads".

Key Points

• In the sentence the error lies in the use of the verb "reads."
• In English language grammar, when we use the base verb after 'to,' it is always in its simplest form.
• Here**, "reads"** should be "read."
• The construction 'to' followed by a basic verb form is known as the infinitive, used commonly after verbs like 'love,' 'like,' 'hate,' etc.
• So, the correct form of the verb in this sentence should be "read" rather than "reads."
• This change would correctly express that he loves the activity of reading books.

Therefore, the correct answer is "Option 2".

The correct answer is 'Capital punishment kills a man at once, but lifelong imprisonment kills him slowly.'

 Key Points

• Option 2 is grammatically correct and follows Standard English Usage.
• The preposition "at" is correctly used in the phrase "at once" to mean "immediately."
• The adverb "slowly" properly modifies the verb "kills," contrasting with the immediate effect of capital punishment.
• The overall sentence structure is grammatically correct and maintains parallelism.
• The sentence conveys a comparison between two severe punishments, emphasizing their different impacts on a person.

Therefore, the correct answer is Option 2.

Additional Information

• Corrected sentence: 'Capital punishment kills a man at once, but lifelong imprisonment kills him slowly.'
• Option 3 has the error "killing him slowly" instead of "kills him slowly." The correct sentence needs to maintain parallelism in verb tense.
• Corrected sentence: 'Capital punishment kills a man at once, but lifelong imprisonment kills him slowly.'
• Option 4 has multiple errors, including "killing a man at once" instead of "kills a man at once" and "kill him slower" instead of "kills him slowly."
• Corrected sentence: 'Capital punishment kills a man at once, but lifelong imprisonment kills him slowly.'

The correct answer is 'changing, stabilising'.

 Key Points

• "Changing" fits with "ambient temperatures," as it refers to varying temperatures that warm-blooded fishes can adapt to.
• "Stabilising" makes sense with body temperatures, as it refers to the ability to maintain or regulate body temperature.
• Warm-blooded fishes' ability to adapt to varying environmental temperatures is by regulating their internal body temperatures.
• The words create a scientifically accurate and coherent sentence that illustrates an attribute of warm-blooded fishes.

Therefore, the correct answer is Option 1.

 Additional Information

• "Recording" means to measure and note, not relevant in this context.
• "Energising" means to give vitality and enthusiasm, not suitable here.
• "Immediate" means occurring or done at once, inappropriate in this context.
• "Revitalising" means to imbue with new life, not suitable for describing temperature regulation.
• "Modifying" means to make partial changes, not fitting with ambient temperatures.
• "Surrendering" means to cease resistance, not suitable for describing temperature control.

The correct answer is "Vigorous".

• Dynamic: Full of energy, vitality, or activity. (ऊर्जा, जीवन शक्ति या गतिविधि से भरपूर)

Additional Information

• Static: Not moving or changing. (गतिहीन या बदलता नहीं)
• Gloomy: Dark, dismal, or depressing. (अंधेरा, निराशाजनक या निराशाजनक)
• Encouraging: Inspiring or motivating. (प्रेरणादायक या प्रेरक)

The correct answer is 'whether'.

 Key Points

• The sentence requires a word that can be used to introduce a direct or indirect question. Among the options, "whether" is the most suitable.
• "Whether" is used to express a doubt or choice between alternatives. In this sentence, it introduces the question of whether elephants are present or not.
• The words "either", "while", and "rather" do not appropriately introduce a doubt or choice between alternatives and therefore would not fit in this context.
• The use of "whether" makes the sentence grammatically and logically correct.

Therefore, the correct answer is Option 4.

 Additional Information

• "Either" typically introduces a choice between two alternatives but does not fit in this context because it is not followed by "or".
• "While" is used to connect two contrasting clauses or to denote something happening at the same time as something else, neither of which applies to this sentence.
• "Rather" is used to indicate a preference or correction, neither of which fits the context of this sentence.

The incorrectly spelt word is: Bureaucracy.

Key Points

• For example, "The country is trying to reduce the size of its bureaucracy to make governmental processes faster."

The correct answer is Option 3. i.e. Random.

• Example: She gave him very specific instructions on how to get there.
• Random (अनियमित) - Made, done, happening, or chosen without method or conscious decision.
• Example: Winners were selected at random.
• From the above example it is clear that Random is opposite to Specific.

Therefore, the correct answer is- Random.

Additional Information

• Topple (गिराना) - Overbalance or cause to overbalance and fall.
• Example: The vase toppled off the shelf.
• Lawful (कानूनी) - Conforming to, permitted by, or recognized by law or rules.

• Stroll (टहलना) - Walk in a leisurely way.

The correct answer is 'swarm'.

• 'Gang', 'stock', 'pack', and 'stack' are not the correct terms for a group of bees.

Therefore, the correct answer is not listed among the options.

The correct answer is 'Option 3) i.e. some'

Key Points

• "Some" implies an unspecified quantity or amount, indicating that the school still requires additional equipment without specifying exactly how much.
• It suggests that while the school has received donations, there is still a need for more equipment to fulfill certain needs.
• This option maintains the sense of need expressed in the sentence while acknowledging the donations already received.
• It fits grammatically and semantically with the sentence structure, conveying the idea of additional equipment required without specifying a large or small number.

Therefore, the correct answer is:Option 3) some

Additional Information

• Option 1) a few: This option suggests a small number, which may not accurately convey the extent of the equipment needed by the school.
• Option 2) many: This option suggests a large number, which may not fit the context of the sentence where the school still needs additional equipment despite donations.
• Option 4) no: This option implies that the school needs no more equipment, which contradicts the premise of the sentence stating that the school still requires additional equipment.

The correct answer is 'without having any proof'.

Key Points

• The original sentence, "It is wrong to make accusations against Farhan without will have any proof," contains a grammatical error. The phrase "without will have any proof" is not grammatically correct.
• The corrected option, "without having any proof," is the appropriate choice. Here's why:
• "Without having any proof": This phrase indicates the absence of evidence or substantiation. It conveys that making accusations against Farhan without any supporting evidence is not advisable or fair. The structure "without having" shows the absence or lack of something—in this case, proof—before making accusations.
• "Without": This term signifies the absence or exclusion of something. In the sentence, it denotes the condition of not having proof before making accusations.
• "Having any proof": This phrase refers to the possession or existence of evidence or substantiation. By using "having any proof," the sentence emphasizes the necessity of having evidence before making accusations against Farhan.
• In contrast, the other options don't provide a grammatically correct structure to convey the intended meaning. For instance, "without has any proof" (option 1), "without being have any proof" (option 2), and "without to be have any proof" (option 3) all contain grammatical errors or awkward constructions that don't accurately convey the idea that accusations should not be made without evidence.
• Therefore, "without having any proof" is the appropriate choice to communicate the idea that making accusations against Farhan without evidence is not the right approach.

Correct Sentence: It is wrong to make accusations against Farhan without having any proof.

The correct answer is 'RPSQ'.

Key Points

• While arranging the parts of the sentence given in options, we have to find some grammatical or contextual connections between them, so let's find out.
• In this sentence, we can see that there are different parts like Subject, Indirect object, subject of subordinating clause and verb, indirect object and direct object.
• The sentence must start with R as it is providing an introduction to the context with the help of 'his favorite subject'.
• The sentence proceeds to give more information about his favorite subject Science which reveals the secrets of life and of nature in P and then in S.
• The sentence further ends with Q by mentioning that these facts were not known men in the past.
• Correct sentence: his favorite subject happens to be Science because Science reveals the secrets of life and of nature which men did not know in the past.

Hence, the correct answer is option (2).

The correct answer is “completely for its”.

Key Points

• The error lies in part 'b' of the sentence.
• We use the preposition ‘to’ following the word ‘owe’.
• The correct expression is 'owe something to someone/something'.
• 'Owe' indicates a debt or a feeling of gratitude for something, and the correct preposition to use after 'owe' is 'to' not 'for'.
• The success is owed "to" something, not "for" something.
• Therefore the correct grammatical structure would be 'owes its success completely to' not 'owes its success completely for'.

Hence, the correct answer is ‘Option 2’.

The correct answer is 'Some areas flourish with life while others are completely devoid of it.'

Key Points

• The correct answer based on the passage is Option 3. The passage illustrates the paradox of the Arctic by contrasting the varied landscapes within the region. It describes how some areas are teeming with life, such as those hosting abundant wildlife like seals, birds, and whales, while other parts of the Arctic are described as "totally devoid of life."
• The line from the passage supporting this is: "Some areas are totally devoid of life, while in others the pulse of life takes our breath away."
• This line underscores the stark contrast between the barren, lifeless regions and the vibrant, thriving ecosystems found in different parts of the Arctic, encapsulating the paradox of the region's diverse landscapes.

The correct answer is 'Excitement and fear'.

Key Points

• The emotions experienced by the voyagers during their journey, as conveyed in the passage, can be best described as option 4. Excitement and fear.
• The passage mentions various emotions felt by the voyagers. For instance, it describes the awe and disappointment of encountering a bowhead whale, the entertainment and occasional fright caused by the wildlife, the caution and respect shown towards encounters with polar bears, and the respect and challenge felt in connection to the ancient Inuit people.
• The line from the passage supporting this is: "At times, these animals scare the living daylights out of us."
• This particular line indicates the sense of fear or startlement that the voyagers experienced during their encounters with the wildlife in the Arctic.
• Additionally, the passage portrays a mix of emotions like awe, respect, and fascination alongside the fear, painting a picture of a journey filled with both excitement and moments of trepidation.

The correct answer is 'Immensity'.

Key Points

• The correct answer is Option 1. Immensity.
• The line from the passage that supports this is: "To revel in its beautiful immensity and to feel its power."
• Here, 'minuteness' implies something small or minute, while 'immensity' refers to vastness or greatness, serving as its antonym. The passage contrasts the desire to experience the grandeur and vastness of the bowhead whale, highlighting the concept of 'immensity' opposite to 'minuteness.'

The correct answer is 'Maclnnis and Beedell's first wind-powered crossing of the Northwest Passage.'

Key Points

• The main focus of the passage is the remarkable feat achieved by Canadians Jeff MacInnis and Mike Beedell - their wind-powered crossing of the Northwest Passage.
• While the text vividly describes encounters with Arctic wildlife and the challenges faced during their expedition, such as encounters with whales, seals, birds, and the environment, these details serve to embellish the central narrative of MacInnis and Beedell's extraordinary accomplishment.
• The passage's primary theme revolves around their historic conquest of the Northwest Passage, showcasing their determination, skill, and perseverance over three summers.

The correct answer is 'Sailing against the wind'.

Key Points

• The idiom that most closely mirrors the perseverance and determination showcased by MacInnis and Beedell during their Northwest Passage expedition is "Sailing against the wind."
• This phrase metaphorically represents the act of persisting and achieving success despite facing numerous challenges and adversities.
• In the context of the passage, MacInnis and Beedell undertook a challenging journey through the Northwest Passage, using wind power and their determination to conquer a route that had previously been elusive to many explorers.
• They navigated against natural elements, relying on their skills and resilience to complete this arduous task over three summers.
• Similar to sailing against the wind, which requires tremendous effort and perseverance, MacInnis and Beedell's expedition demanded resilience, determination, and the ability to overcome obstacles.
• This idiom encapsulates their unwavering spirit and persistence in achieving their historic feat despite the hardships encountered along the way.

The correct answer is Give me blood and I will give you freedom.

Shortcut Trick

The time after which all bells ring together is the LCM of their individual ringing intervals.

LCM of 6, 7, 9, and 12 = 252 seconds.

Since the bells ring together every 252 seconds, we check for 252 or its multiples in the options.

Next multiple = 252 × 2 = 504 seconds, which matches an option.

∴ The correct answer is 504 seconds.

Alternate Method

Given:

Intervals at which the four bells ring = 6, 7, 9, and 12 seconds.

Concept Used:

The bells will ring together again after a time that is exactly divisible by all the individual intervals. This specific time represents the Least Common Multiple (LCM) of the given numbers. If the exact LCM is not among the options, any integer multiple of the LCM is a valid answer since the bells continue to ring together periodically.

Calculations:

⇒ Prime factorization of 6 = 2 × 3

⇒ Prime factorization of 7 = 7

⇒ Prime factorization of 9 = 3²

⇒ Prime factorization of 12 = 2² × 3

⇒ LCM = Product of the highest powers of all present prime factors

⇒ LCM = 2² × 3² × 7

⇒ LCM = 4 × 9 × 7 = 252 seconds

⇒ This means the bells will ring together every 252 seconds (i.e., at 252s, 504s, 756s, etc.).

⇒ Analyzing the given options, we find that 504 is exactly divisible by 252 (252 × 2 = 504).

∴ The correct answer is 504 seconds.

Additional Information

LCM for Periodic Events

For events that repeat at different regular intervals (like bells tolling, traffic lights changing, or runners on a circular track), they will all occur together again at exactly the LCM of their individual intervals.

Multiples of LCM

If the events coincide for the first time at the LCM, they will continue to simultaneously coincide at every successive integer multiple of the LCM (e.g., 2 × LCM, 3 × LCM).

HCF for Maximum Grouping

While LCM is for simultaneous forward occurrences, the Highest Common Factor (HCF) is used when dividing items into the largest possible equal groups without leaving any remainder (e.g., cutting ropes into maximum equal lengths).

Shortcut Trick

Let CP = x and SP = y. Original Profit = y − x.

New SP = 2y. New Profit = 2y − x.

According to the question: 2y − x = 4 × (y − x).

⇒ 2y − x = 4y − 4x ⇒ 3x = 2y ⇒ y/x = 3/2.

Profit % = (3 − 2) ÷ 2 × 100 = 1/2 × 100 = 50%.

∴ The correct answer is 50%.

Alternate Method

Given: New SP is twice the original SP; New Profit is four times the original profit.

Formulas: Profit = SP − CP | Profit% = (Profit ÷ CP) × 100

⇒ Let CP = 100 and Profit = P. Then SP = 100 + P.

⇒ New SP = 2 × (100 + P) = 200 + 2P.

⇒ New Profit = New SP − CP = (200 + 2P) − 100 = 100 + 2P.

⇒ According to the condition: 100 + 2P = 4P.

⇒ 2P = 100 ⇒ P = 50.

⇒ Profit% = (50 ÷ 100) × 100 = 50%.

∴ The correct answer is 50%.

Additional Information

Profit and Loss Basic Concepts

Profit occurs when the selling price (SP) is greater than the cost price (CP). Profit = SP − CP.

Percentage Calculation

Profit percentage is always calculated on the Cost Price (CP) unless stated otherwise. Profit% = (Profit/CP) × 100.

Shortcut Trick

Lateral Surface Area is proportional to the square of the edge (LSA ∝ edge²).

Using the successive percentage formula: x + y + (x × y / 100).

Here x = 50% and y = 50%.

Required percentage increase = 50 + 50 + (50 × 50 / 100) = 125%.

∴ The correct answer is 125%.

Alternate Method

Given:

Percentage increase in each edge of the cube = 50%

Formula Used:

Lateral Surface Area (LSA) of a cube = 4 × (edge)²

Edge = a Initial LSA = 4a²

+50%

Edge = 1.5a New LSA = 9a²

Calculations:

⇒ Let the initial edge of the cube be a.

⇒ Initial lateral surface area = 4 × a²

⇒ New edge = a + 50% of a = 1.5a

⇒ New lateral surface area = 4 × (1.5a)²

⇒ New lateral surface area = 4 × 2.25a² = 9a²

⇒ Increase in LSA = 9a² − 4a² = 5a²

⇒ Percentage increase = (Increase / Initial LSA) × 100

⇒ Percentage increase = (5a² / 4a²) × 100

⇒ Percentage increase = 1.25 × 100 = 125%

∴ The correct answer is 125%.

Additional Information

Total Surface Area (TSA)

The TSA of a cube is 6a². If the edge increases by x%, the percentage increase in TSA is the same as the increase in LSA.

Volume Increase

The volume of a cube is a³. If the edge increases by x%, the volume increase is [(1 + x/100)³ − 1] × 100%.

Successive Percentage Formula

For any 2D dimension change (Area), the net change is a + b + (a × b / 100). For a cube, a = b = edge change %.

Shortcut Trick

The efficiency (flow rate) of a pipe is directly proportional to the square of its diameter.

Since the new pipes have double the diameter, their efficiency is 2² = 4 times that of the original pipes.

Total capacity of the cistern = 15 pipes × 1 unit × 12 minutes = 180 units.

Total efficiency of 6 new pipes = 6 × 4 units = 24 units/minute.

Time required = Total capacity ÷ New efficiency = 180 ÷ 24 = 7.5 minutes.

∴ The correct answer is 7.5 minutes.

Alternate Method

Given:

⇒ Number of original pipes = 15

⇒ Time taken by original pipes = 12 minutes

⇒ Number of new pipes = 6

⇒ Diameter of new pipes = 2 × Original diameter

Formula Used:

⇒ Flow Rate (Efficiency) ∝ (Diameter)²

⇒ Total Work = Number of Pipes × Efficiency per pipe × Time

Calculations:

⇒ Let the efficiency of 1 original pipe be 1 unit/min.

⇒ The new pipe has twice the original diameter, so its cross-sectional area and efficiency become 2² = 4 units/min.

⇒ Total combined efficiency of 15 original pipes = 15 × 1 = 15 units/min.

⇒ Total capacity of the cistern = Total original efficiency × Time taken = 15 × 12 = 180 units.

⇒ Total combined efficiency of 6 new pipes = 6 × 4 = 24 units/min.

⇒ Time required by new pipes = Total Capacity ÷ Combined New Efficiency

⇒ Time required = 180 ÷ 24 = 7.5 minutes.

∴ The correct answer is 7.5 minutes.

Additional Information

Pipes and Cisterns Flow Rule

When the speed of the fluid is constant, the volume of liquid flowing out is strictly proportional to the cross-sectional area of the pipe. Hence, Flow Rate ∝ r² or d².

MDH Work Equivalence Formula

Total work remains constant and can be solved using the chain rule: M₁ × D₁ × E₁ = M₂ × D₂ × E₂, where M is the number of pipes, D is the time elapsed, and E is the specific flow efficiency.

Rate & Efficiency Trick

If a pipe's radius or diameter is scaled by a factor of 'k', its filling capacity per unit of time scales by a factor of 'k²'. Time needed will correspondingly reduce by a factor of 'k²' for a single pipe.

Given:

84 ÷ 32 × 8 - 15 ÷ 8 × (19 - 35)

Concept used:

Calculation:

84 ÷ 32 × 8 - 15 ÷ 8 × (19 - 35)

⇒ 84 ÷ 32 × 8 - 15 ÷ 8 × (- 16)

⇒ 21/8 × 8 - (15/8) × (- 16)

⇒ 21 + 30

⇒ 51

∴ The required answer is 51.

Shortcut Trick

The total capacity of the tank is the product of the number of taps and the time taken: 15 × 36 = 540 tap-minutes.

To find the number of taps for a new time of 60 minutes (1 hour), divide the total capacity by the new time.

Required taps = 540 ÷ 60 = 9.

∴ The correct answer is 9.

Alternate Method

Given:

Initial number of taps (M₁) = 15

Initial time (T₁) = 36 minutes

Required time (T₂) = 1 hour = 60 minutes

Formula Used:

For a constant work (filling the same tank), the formula is: M₁ × T₁ = M₂ × T₂

Calculations:

⇒ Total Work = 15 × 36 = 540 units

⇒ M₂ × 60 = 540

⇒ M₂ = 540 ÷ 60

⇒ M₂ = 9

∴ The correct answer is 9.

Additional Information

Inverse Proportion

For a constant task, the number of resources (taps/men) is inversely proportional to the time taken. If time increases, fewer taps are needed.

Pipes and Cisterns

This concept follows the same logic as Time and Work, where the rate of filling is the efficiency of the pipe or tap.

Chain Rule Formula

The general formula for such problems is M₁ × D₁ × H₁ ÷ W₁ = M₂ × D₂ × H₂ ÷ W₂, where W represents the work done.

Shortcut Trick

Deviation of the newly adopted girl's age from the current average = 11 − 15 = −4 years.

This deficit of 4 years will be shared equally among all 4 girls (3 current + 1 new).

Change in average = −4 ÷ 4 = −1 year.

New average = 15 − 1 = 14 years.

∴ The correct answer is 14 years.

Alternate Method

Given:

Number of current daughters = 3

Average age of the 3 daughters = 15 years

Age of the adopted girl = 11 years

Formula Used:

Average = Total Sum of Observations ÷ Total Number of Observations

Current Daughters & Adopted Girl:

15

15

15

11

Sum = 56

New Average (Equally Distributed):

14

14

Avg = 14

Calculations:

⇒ Total age of 3 daughters = 3 × 15 = 45 years

⇒ Total age of all girls after adoption = 45 + 11 = 56 years

⇒ Total number of girls after adoption = 3 + 1 = 4

⇒ New average age = 56 ÷ 4 = 14 years

∴ The correct answer is 14 years.

Additional Information

Weighted Average

If group 1 has n₁ items with an average of A₁, and group 2 has n₂ items with an average of A₂, then the Combined Average = (n₁A₁ + n₂A₂) ÷ (n₁ + n₂).

Average Replacement

If an existing person is replaced by a new person and the overall average increases by x, the new person's value = Old person's value + (Total persons × x).

Effect of Arithmetic Operations

If each given observation in a set is systematically increased, decreased, multiplied, or divided by a constant value 'k', then the average of the set will also undergo the same exact operation by 'k'.

Shortcut Trick

Perimeter of Square = Circumference of Circle

4 × Side = 2 × π × Radius

4 × 66 = 2 × (22/7) × r

264 = (44/7) × r

r = (264 × 7) ÷ 44 = 6 × 7 = 42 cm

∴ The correct answer is 42 cm.

Alternate Method

Given:

Side of the square (a) = 66 cm

Formula Used:

Perimeter of square = 4 × a

Circumference of circle = 2 × π × r

Calculations:

⇒ Length of wire = Perimeter of square

⇒ Length of wire = 4 × 66 = 264 cm

⇒ Since the same wire is bent into a circle:

⇒ 2 × π × r = 264

⇒ 2 × (22/7) × r = 264

⇒ (44/7) × r = 264

⇒ r = (264 × 7) ÷ 44

⇒ r = 6 × 7

⇒ r = 42 cm

∴ The correct answer is 42 cm.

Additional Information

Perimeter and Area of Square

Perimeter = 4 × side and Area = side². The diagonal of a square is side × √2.

Circumference and Area of Circle

Circumference = 2πr and Area = πr², where r is the radius and π ≈ 22/7 or 3.14.

Shape Transformation Rule
