The correct answer is 'Utter'.

Key Points

• The given word 'Sheer' signifies something that is nothing less than complete or absolute. (परिपूर्ण or सम्पूर्ण)
• Example: The sheer number of motivational books available is overwhelming, indicating that the number is absolutely vast.
• The correct word 'Utter' also stands for complete or absolute, i.e., it corresponds to the same meaning of 'Sheer'. (परिपूर्ण or एकदम)
• Example: He was in utter disbelief when he won the lottery, meaning he was in complete disbelief.
• Hence, the correct synonym for 'Sheer' is 'Utter'.

Therefore, the correct answer is- "Option 4".

• 'Infinity' refers to an endless or limitless quantity or extent of something. (अनन्त)

The correct answer is 'They oversimplify the subjective nature of motivation'.

Key Points

• The passage mentions that motivational books aimed at youth often simplify motivation, which is inherently a personal and subjective experience.
• They propose a series of simple steps, portraying a 'one-size-fits-all' path toward success.
• Even though these steps might inspire temporarily, they rarely contribute to lasting motivation.
• This oversimplification represents a complexity that is associated with the convenience of motivational books.

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

Additional Information

• Options 'They offer too many success stories', 'They disrupt the reading habits of the youth', 'They are too expensive for young people', and 'They are often outdated' are not mentioned in the passage as complexities associated with the convenience of motivational books.

The correct answer is 'Maintain'.

Key Points

• The term 'Retain' in the context of the text means to continue to have, keep possession of, or not lose something. (कायम रखना or धारण करना)
• Example: Difficulty retaining fleeting inspiration from motivational books suggests a difficulty in continuing to have or keep the inspiration derived from these books.
• The correct word 'Maintain' is a synonym for 'retain', and it means to keep in an existing state, to preserve from failure or decline. (बनाए रखना)
• Example: We must maintain high standards of cleanliness, implying we need to keep high standards of cleanliness intact.
• Hence, the correct synonym for 'Retain' is 'Maintain'.

Therefore, the correct answer is- "Option 1".

 Additional Information

• 'Disperse' means to distribute or spread over a wide area, scatter. (छितरना or विकीर्ण करना)
• 'Relinquish' means to voluntarily cease to keep or claim; to give up. (त्यागना)
• 'Neglect' means to fail to care for, or to disregard. (उपेक्षा करना)
• ‘Dismiss’ means to refuse to consider an idea or opinion. (खारिज करना)

The correct answer is 'Difficulty in sustaining the inspired motivation'.

Key Points

• The passage acknowledges the issue with retaining the inspiration that these motivational books might initially spark.
• The motivational surge often experienced during or right after reading isn't typically sustainable.
• As everyday life continues, the inspiration decreases, often leaving readers back at their beginning point or even more demotivated than they were prior to reading.
• Therefore, this challenge is associated with the effectiveness of these motivational books.

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

 Additional Information

• 'The lack of personal testimonies', 'The broad scope of the contents', 'The language used is too complex for the youth', and 'The books are not accessible enough' are not outlined in the passage as the challenges of the effectiveness of motivational books.

The correct antonym is 'Undermining'.

Key Points

• The given word is 'Sustainable', which refers to the ability to be maintained or kept going continuously. (सतत or धारण करने योग्य)
• Example: The company's sustainable growth can be attributed to its robust investment strategies.
• The correct antonym 'Undermining' refers to the action that lessens the effectiveness, power, or ability of something or someone. (कमजोर करना or अवमूल्यन करना)
• Example: Constant criticism is undermining my confidence.
• Hence, the correct antonym is 'Undermining'.

Therefore, the correct answer is 'Option 4'.

Additional Information

• 'Preservable' refers to the ability to maintain something (or defend) something in its present condition. (संरक्षित करने योग्य)
• 'Upholdable' implies something that can be supported or defended. (समर्थन योग्य)
• 'Extendable' suggests that something can be made larger or more widespread. (विस्तार योग्य)
• 'Protractable' refers to drawing out or lengthening in time. (विलंबित करने योग्य)

The correct answer is 'The books cannot be the definitive path to success'.

Key Points

• The passage advises adopting a cautious approach towards motivational literature for youth as a definitive guide to success.
• It explicitly mentions that these books might serve as an element but must not be viewed as a comprehensive, magic solution or silver bullet to success.
• Instead, the passage emphasizes fostering intrinsic motivation, which is derived from self-reflection, life experiences, and personal values, as the foundation for sustainable success.
• Therefore, young readers are encouraged to view these books as part of their broader journey towards self-growth and development, rather than as the sole, comprehensive route to success.

Therefore, the correct answer is - 'Option 4'.

 Additional Information

• Options 'The books cannot replace practical life experience' and 'The books might discourage readers from pursuing their own goals' contain elements of truth based on the passage, but they don't convey the exact reason which passage suggests to take cautious approach to motivational literature.
• Options 'The books lack credibility and authenticity' and 'The books often lack quality and depth' are never stated or implied in the passage as reasons for the recommended cautious approach.

The correct answer is 'Impotency'.

Key Points

• The given word is 'Effectiveness', which means the degree to which something is successful in producing a desired result. (प्रभावशीलता)
• Example: The effectiveness of the council's approach to parking has been a controversial issue.
• The correct antonym, 'Impotency' refers to the lack of power or ability to do something. (अशक्तता or असमर्थता)
• Example: The opposition levelled their criticism at the government’s impotency in dealing with the crisis.
• Hence, the correct antonym is 'impotency'.

Therefore, the correct answer is 'Option 2'.

Additional Information

• 'Potency' refers to the power or ability of something to affect the mind or body. (शक्ति or ताकत)
• 'Efficiency' signifies the ability to do tasks well without wasting time or energy. (कार्यक्षमता or दक्षता)
• 'Practicality' involves considering the realistic aspects of a situation and making decisions based on that. ( व्यावहारिकता)
• 'Dynamism' refers to the quality of being dynamic, characterized by constant change or activity. (गतिशीलता or अग्रसरता)

The correct answer is 'A, B, and C'.

Key Points

• Statement A: The passage clearly states that motivational books can potentially serve as a start towards self-growth and development. They offer practical tips and inspire through shared stories; they can even stimulate the journey of self-growth and discovery.
• Statement B: The passage mentions that these books propose a 'one-size-fits-all' path towards success. They offer steps that simplify motivation, which might be a temporary inspiration, but do not contribute to long-lasting motivation.
• Statement C: The passage also states that the motivational surge often experienced during or right after reading is not sustainable. As everyday life resumes, the inspiration fades, leaving readers back at their starting point or even more demotivated than they were before.

Therefore, the correct answer is - 'Option 5'.

 Additional Information

• Although the 'Only A', 'A and B', 'B and C', 'A and C' options contain true statements, they do not include all correct statements from the passage. The passage supports all statements A, B, and C.

The correct answer is 'Youth Motivation: The Role and Limitations of Motivational Books'.

Key Points

• This title clearly encapsulates the central idea of the passage, which discusses both the contributions and the limitations of motivational books aiming to inspire youth.
• The passage narrates the role of these books by mentioning how they propose new ways of thinking and potentially initiate self-growth and development.
• It also articulates the limitations of these books, such as the oversimplification of motivation and the challenges in sustaining motivation.

Therefore, the correct answer is - ‘Option 5’.

 Additional Information

• The remaining options do not accurately sum up the central idea presented in the passage. Options such as 'The Unseen Dangers of Motivational Literature', 'Dissecting Motivational Literature for Youth', 'The Ineffectiveness of Self-help Books', and 'The Mediocre Influence of Motivational Books' either excessively focus on the limitations or do not sufficiently cover the various aspects of the passage.

The correct answer is 'B'

 Key Points

• The error in the sentence is in part 'B'.
• The phrase 'technology playing' miss an auxiliary verb, 'is', before the verb 'playing'.
• The correct sentence: "In the modern world, technology is playing an integral role in our daily lives."

Therefore, the correct answer is Option 2 - 'B'.

 Additional Information

Remember, the structure for the present continuous tense is subject + auxiliary verb 'is/are' + '-ing' form of the main verb.

The correct answer is 'B'

 Key Points

• The error in the sentence is located in part 'B'.
• The word 'then' is incorrect in this context; the word 'then' is predominantly used as an adverb to situate sequence of actions in time.
• The correct word to use when expressing preference is 'to'.
• The corrected sentence should read: "He preferred coffee to tea because it was stronger."

Therefore, the correct answer is Option 2 - 'B'.

 Additional Information

'The phrase 'prefer ... to ...' is used to indicate that you like one thing or activity more than another. The word 'then' should not be used to compare preferences. Make sure that 'then' is not mistaken for 'than', which is used in comparative statements.

The correct answer is 'A' i.e. this part of the sentence has an error.

Key Points

• In the first part of the given sentence, the use of the plural form of the verb 'were' is incorrect.
• Collective nouns which refer to a group of people or things can take either a singular verb or a plural one depending on the meaning that is being implied.
• If the collective noun is taken to represent the group as one whole (here, The audience), then the singular form of the verb is used.
• Example: The audience was cheering the performer.
• The singular form of the verb "was" should be used with the singular subject 'The audience'.
• Therefore, the singular form of the verb 'was' should be used in place of the plural form 'were'.
  

Hence, the correct answer is option 1.

Correct sentence: The audience was becoming restive as they waited for the performance to begin.

Additional Information

• If individual members are implied, then the verb takes the plural form.
• Example: When the play ended, the audience were reluctant to leave.

The correct answer is 'B' i.e. this part of the sentence has an error.

Key Points

• In the second part of the given sentence, the use of the noun 'irrelevance' is incorrect.
• The noun 'irrelevance' means the quality or state of not having anything to do with the matter at hand. (अप्रासंगिकता, असंबद्घता)
• The adverb 'strictly' indicates that an adjective should be followed.
• Therefore, the adjective 'irrelevant' should be used in place of the noun 'irrelevance'.
• The adjective 'irrelevant' means not connected with something or important to it. (किसी वस्‍तु से असंबद्घ या उसके लिए महत्वहीन, अप्रासंगिक, असंबद्घ)
• Therefore, the adjective 'irrelevant' should be used in place of the noun 'irrelevance'.
  

Hence, the correct answer is option 2.

Correct sentence: The matter is strictly irrelevant at this point in the proceedings.

The correct answer is 'C' i.e. this part of the sentence has an error.

Key Points

• In the third part of the given sentence, the use of the adverb 'then' is incorrect.
• The adverbs "scarcely, hardly, and barely" are always followed by the adverb 'when' and not 'then'.
• "Scarcely...when" is used to combine or rewrite sentences denoting two simultaneous past actions.
• For example:
• Incorrect: Scarcely she had entered the room then everyone got quiet.
  

Correct: Scarcely had she entered the room when everyone got quiet.

Hence, the correct answer is option 3.

Correct sentence: Scarcely had I got through the door when the phone rang.

The correct answer is option 4.

Given series:

100, 91, 81, 70, 60, 45

Calculation :

The series follows the following pattern:

Shortcut Trick

Ratio of Perimeter (P) to Length (L) = 3 : 1

Let P = 3 units, then L = 1 unit.

Since P = 2(L + B) ⇒ 3 = 2(1 + B) ⇒ 1.5 = 1 + B ⇒ Breadth (B) = 0.5 units.

Required Ratio (B : P) = 0.5 : 3 = 1 : 6.

∴ The correct answer is 1 : 6.

Alternate Method

Given: Ratio P : L = 3 : 1 and Perimeter (P) = 108 cm.

Formula: Perimeter of rectangle = 2 × (Length + Breadth)

⇒ 3 units = 108 cm

⇒ 1 unit (Length) = 108 ÷ 3 = 36 cm

⇒ Perimeter = 2 × (Length + Breadth)

⇒ 108 = 2 × (36 + Breadth)

⇒ 54 = 36 + Breadth

⇒ Breadth = 18 cm

⇒ Ratio of Breadth to Perimeter = 18 : 108

⇒ Ratio = 1 : 6

∴ The correct answer is 1 : 6.

Additional Information

Area of Rectangle

The total space occupied by the rectangle is given by the product of its dimensions: Area = Length × Breadth.

Ratio of Profit Share = (Investment₁ × Time₁) : (Investment₂ × Time₂)

Priya : Soni = (57,000 × 12) : (95,000 × 6)

Divide by 1000 × 6: (57 × 2) : 95 = 114 : 95 = 6 : 5

Total units = 6 + 5 = 11 units. Given total profit = Rs. 22,000.

1 unit = 22,000 ÷ 11 = 2,000. Soni profit share = 5 × 2,000 = Rs. 10,000.

∴ The correct answer is Rs. 10,000.

Alternate Method

Given → Priya Investment = Rs. 57,000 for 12 months | Soni Investment = Rs. 95,000 for 6 months. Formulas: Profit Share = Investment × Time Period

⇒ Priya total value = 57,000 × 12 = 6,84,000 ⇒ Soni total value = 95,000 × 6 = 5,70,000 ⇒ Ratio Priya : Soni = 684,000 : 570,000 = 684 : 570 ⇒ Simplify by 114: Ratio = 6 : 5 ⇒ Soni share = [5 ÷ (6 + 5)] × 22,000 ⇒ Soni share = (5 ÷ 11) × 22,000 = 5 × 2,000 = 10,000

∴ The correct answer is Rs. 10,000.

Shortcut Trick

Downstream speed (v) = 6 + 2 = 8 km/hr

Upstream speed (u) = 6 − 2 = 4 km/hr

Distance (D) = [u × v × (Time Difference)] ÷ (v − u)

Distance (D) = [4 × 8 × (40/60)] ÷ (8 − 4) = [32 × (2/3)] ÷ 4 = 16/3 km

∴ The correct answer is 16/3 km.

Alternate Method

Given:

Speed of man in still water (x) = 6 km/hr

Speed of stream (y) = 2 km/hr

Time difference = 40 minutes = 40/60 hours = 2/3 hours

Calculations:

⇒ Downstream speed = x + y = 6 + 2 = 8 km/hr

⇒ Upstream speed = x − y = 6 − 2 = 4 km/hr

⇒ Time = Distance ÷ Speed

⇒ (D/4) − (D/8) = 2/3

⇒ (2D − D)/8 = 2/3

⇒ D/8 = 2/3

⇒ D = 16/3 km

∴ The correct answer is 16/3 km.

Additional Information

Downstream and Upstream Speed

Downstream Speed = Speed in Still Water + Stream Speed. Upstream Speed = Speed in Still Water − Stream Speed.

Calculating Water/Stream Speed

Speed in Still Water = (Downstream + Upstream) ÷ 2. Stream Speed = (Downstream − Upstream) ÷ 2.

Weight of staff member who left = Old Average − (Decrease × New Strength) = 50 − (−1 × 9) = 59 kg.

Weight of staff member who joined = Old Average + (Increase × New Strength) = 49 + (3 × 10) = 79 kg.

Difference = 79 − 59 = 20 kg.

∴ The correct answer is 20 kg.

Alternate Method

Given: Initial 10 staff avg = 50 kg; After 1 left (9 staff) avg = 49 kg; After 1 joined (10 staff) avg = 52 kg.

Formula: Total Weight = Average × Number of members

⇒ Total weight of 10 initial staff members = 10 × 50 = 500 kg.

⇒ Total weight after 1 staff member left (9 members) = 9 × 49 = 441 kg.

⇒ Weight of staff member who left = 500 − 441 = 59 kg.

⇒ Total weight after new staff member joins (10 members) = 10 × 52 = 520 kg.

⇒ Weight of staff member who joined = 520 − 441 = 79 kg.

⇒ Difference = 79 − 59 = 20 kg.

∴ The correct answer is 20 kg.

Additional Information

Average weight change

If the average increases, the weight of the new person is New Weight = Old Average + (Increase × New Strength).

Excluded value

When a member is excluded and the average decreases, the excluded value = Old Average + (Decrease × New Strength).

Additional Information

Mixture Removal Property

When a portion of a mixture is removed, the ratio of components in the remaining mixture stays the same as the original ratio.

Alligation Rule

Quantity of Cheaper / Quantity of Dearer = (Rate of Dearer − Mean Rate) / (Mean Rate − Rate of Cheaper). This is used for mixing two varieties.

Replacement Formula

Final Quantity = Initial Quantity × [1 − (Removed Amount / Total Capacity)]ⁿ, where n is the number of replacement operations.

Shortcut Trick

Effective Simple Interest rate for 3 years = 7% × 3 = 21%.

Total Amount in percentage = 100% (Principal) + 21% (Interest) = 121%.

Given: 121% → Rs. 4,840.

Principal (100%) = (4840 ÷ 121) × 100 = 40 × 100 = Rs. 4,000.

∴ The correct answer is Rs. 4000.

Alternate Method

Given:

Rate of Interest (R) = 7% p.a.

Time Period (T) = 3 years

Amount (A) = Rs. 4,840

Formula Used:

Simple Interest (SI) = (P × R × T) ÷ 100

Amount (A) = Principal (P) + SI = P + (P × R × T) ÷ 100 = P[1 + (RT ÷ 100)]

Calculations:

⇒ 4840 = P[1 + (7 × 3 ÷ 100)]

⇒ 4840 = P[1 + 21 ÷ 100]

⇒ 4840 = P[121 ÷ 100]

⇒ P = (4840 × 100) ÷ 121

⇒ P = 40 × 100

⇒ P = Rs. 4,000

∴ The correct answer is Rs. 4000.

Additional Information

Simple Interest Concept

Simple interest is calculated only on the Principal amount. It remains constant every year if the rate and principal are unchanged.

Difference between SI and CI

For the first year, SI and Compound Interest (CI) are equal. From the second year onwards, CI > SI because CI is calculated on the accumulated amount.

Rate of Interest Formula

If Principal, Time, and Interest are known, the rate can be found as: R = (SI × 100) ÷ (P × T).

Shortcut Trick

Difference in Discount % = 20% − 10% = 10% of Marked Price (MP).

Difference in Profit Amount = Rs. 4000 − Rs. 3300 = Rs. 700.

Since Cost Price (CP) is constant, the decrease in Profit is exactly equal to the increase in Discount.

∴ 10% of MP = Rs. 700.

⇒ 100% of MP = Rs. 700 × 10 = Rs. 7,000.

∴ The correct answer is Rs. 7,000.

Alternate Method

Given → Discount₁ = 10%, Profit₁ = Rs. 4000; Discount₂ = 20%, Profit₂ = Rs. 3300. Formulas: SP = MP − Discount | Profit = SP − CP | SP = CP + Profit.

Let the Marked Price be M.

⇒ Case 1: SP₁ = M − 0.10M = 0.90M. CP = 0.90M − 4000.

⇒ Case 2: SP₂ = M − 0.20M = 0.80M. CP = 0.80M − 3300.

⇒ Since CP is same: 0.90M − 4000 = 0.80M − 3300.

⇒ 0.90M − 0.80M = 4000 − 3300.

⇒ 0.10M = 700 ⇒ M = 700 ÷ 0.10 = 7000.

∴ The correct answer is Rs. 7,000.

Additional Information

Marked Price & Selling Price

Marked Price is the price listed on the tag. Discount is always calculated on MP: SP = MP × (100 − D%)/100.

Relation between CP and MP

CP × (100 + P%) = MP × (100 − D%). This ratio is helpful when Profit% and Discount% are both given.

Shortcut Trick

Days for B alone = (A × Combined) ÷ (A − Combined)

Days = (48 × 24) ÷ (48 − 24)

Days = (48 × 24) ÷ 24 = 48 days

∴ The correct answer is 48 days.

Alternate Method

Given: A and B together take 24 days, A takes 48 days.

Formula: Total Work = LCM of Days; Efficiency = Work ÷ Days

⇒ Efficiency of B = Efficiency of (A + B) − Efficiency of A

⇒ Efficiency of B = 2 − 1 = 1 unit/day

⇒ Time taken by B = Total Work ÷ Efficiency of B

⇒ Time taken by B = 48 ÷ 1 = 48 days

∴ The correct answer is 48 days.

Additional Information

Work and Efficiency Relation

Efficiency is inversely proportional to the time taken to complete a work. Efficiency = Work / Time.

Combined Work Formula

If two people take x and y days respectively, they together take (xy) / (x + y) days to finish the work.

Combine the ratio of A : B (1 : 3) and A : C (2 : 3) by making A common: A : B : C = 2 : 6 : 3.

Difference between A and C (3 − 2 = 1 unit) is given as 2 years.

Present total units = 2 + 6 + 3 = 11 units ⇒ 11 × 2 = 22 years.

Sum after 14 years = 22 + (3 × 14) = 22 + 42 = 64 years.

∴ The correct answer is 64 years.

Alternate Method

Given: Ratio A : B = 1 : 3 and Ratio A : C = 2 : 3.

Formula: Sum of ages = (A + B + C) + (3 × years hence).

⇒ To unify ratios, multiply A : B by 2: A : B = 2 : 6.

⇒ Unified ratio A : B : C = 2 : 6 : 3.

⇒ Difference (C − A) = 3x − 2x = x.

⇒ Given x = 2 years.

⇒ Present age of A = 2 × 2 = 4, B = 6 × 2 = 12, C = 3 × 2 = 6.

⇒ Present sum = 4 + 12 + 6 = 22 years.

⇒ Sum after 14 years = 22 + (14 + 14 + 14) = 22 + 42 = 64 years.

∴ The correct answer is 64 years.

Additional Information

Ratio Equalization

To combine two ratios (A:B and A:C), make the common term (A) equal by multiplying both ratios with appropriate constants.

Age Sum Property

When calculating the sum of ages of n people after t years, the total sum increases by n × t years.

Age Difference Property

The difference between the ages of two individuals remains constant at any point in time.

Shortcut Trick

Speed in m/s = 36 × 5/18 = 10 m/s.

Train Length = Speed × Time = 10 × 10 = 100 m.

Total Distance to cross platform = 100 + 60 = 160 m.

Time Required = 160 ÷ 10 = 16 s.

∴ The correct answer is 16 s.

Alternate Method

Given:

Speed of train = 36 km/hr

Time to cross man = 10 s

Length of platform = 60 m

Formula Used:

Speed = Distance ÷ Time

1 km/hr = 5/18 m/s

Calculations:

⇒ Speed = 36 × (5/18) = 10 m/s

⇒ Length of Train (L_t) = Speed × Time_man = 10 × 10 = 100 m

⇒ Total Distance to cross platform = L_t + Length of Platform = 100 + 60 = 160 m

⇒ Time to cross platform = Total Distance ÷ Speed = 160 ÷ 10 = 16 s

∴ The correct answer is 16 s.

Additional Information

Relative Speed

When two objects move in the same direction, relative speed = S₁ − S₂. In opposite directions, relative speed = S₁ + S₂.

Crossing Stationary Objects

To cross a point object (man, pole), distance = train length. To cross an extended object (bridge, platform), distance = train length + object length.

Unit Conversion

To convert km/hr to m/s, multiply by 5/18. To convert m/s to km/hr, multiply by 18/5.
