Although all the words given in the options are synonymous in a way, the contexts in which they are used vary.  ‘Advent’ means the arrival of something of importance. Computers and internet are things of importance and thus ‘advent’ is the best option here.

The word ‘but’ in the sentence indicates that whatever is mentioned after it will be contradictory to anything mentioned before it. Hence, one should look for a word that indicates the unfavourable effects of the technological advancements. ‘Unscrupulous’ meaning dishonest and unfair is irrelevant.  ‘Unpropitious’ means not favouring success. ‘Averse’ means having a strong dislike for something. ‘Unlucky is out of context. The correct word to fill this blank is ‘adverse’ which means unfavourable and is the right word to describe the  contrasting effect of the internet  on our interpersonal lives.

Blank (C) requires a verb that conveys the meaning of ‘through’. ‘Vis-a-vis’ means with regard to. ‘Albeit’ means ‘though’. ‘Sans’ means without and ‘en route’ means on the way. The correct choice is ‘via’ which means ‘through’ or ‘by the way of’.

Careful reading of the sentence will make it clear that the portion of the sentence after the comma speaks about the demerits of technology, while the one before the comma states it merits. Hence a contrastive conjunction is required in the beginning of the sentence. ‘Although’ is the correct answer.

The choices in the simple present tense are ruled as the sentence is in present perfect. ‘Concealed’ means hidden or kept secret. ‘Unfrequented’ means visited rarely. ‘Sequestered’ which means isolated is the correct choice.

The correct answer is: 'Option 2'.

Key Points

• The error part lies in 'Part 'B' of the sentence that is: 'visiting India are increasing'.
• The given sentence starts with 'The number of'. According to the rule of it, 'Singular verb' is used after 'The number of'.
• So, replacing 'are' with 'is' in the sentence will make it correct.
• Hence, the correct answer is: 'B'.
• Correct sentence: The number of foreign tourists visiting India is increasing day by day during this tourist season.

The correct answer is: 'Option 2'.

Key Points

• The error part lies in Part 'B' that is; 'five lakhs rupees compensation'.
• The given sentence has an error of 'Number + Unit + Noun'. Here, 'Number' is 'five', 'Unit' is 'lakhs', 'Noun' is 'rupees'.
• According to the rule, Singular form of the Unit that is; 'Lakh' will be used here to make the sentence correct.
• Hence, the correct answer is: 'B'.
• Correct sentence: Chief Minister of the state has announced five lakh rupees compensation for the family of those killed in the flood and rain.

The correct answer is Option 5.

Key Points

• The primary issue in the sentence is the incorrect usage of the term "layoff."
• The term "layoff" is a noun and should be changed to the phrasal verb "lay off."
• To ensure grammatical correctness, "lay off" should be used in the context of the sentence.
• Thus, the error is located in part B of the sentence.

Therefore, the correct answer is B.

Correct Sentence: "The company has decided to lay off a few employees due to the recent financial downturn."

Additional Information

• A: "The company has decided to" – This part of the sentence is grammatically correct and does not require any changes.
• C: "due to the recent" – This part of the sentence is grammatically correct and does not require any changes.
• D: "financial downturn." – This part of the sentence is grammatically correct and does not require any changes.
• No error – This would be the correct option if there were no mistakes in the sentence, but there is an error in part B.

The correct answer is "Option 3".

Key Points

• The erroneous part is "their".
• Here, the subject "the company" is singular, so it should be followed by the singular possessive pronoun "its".
• The word "their" is incorrect in this context because it is a plural possessive pronoun.
• Example: The guitar is useless without its strings.
• Hence, the erroneous part is "their".

Therefore, the correct answer is "Option 3".

Correct Sentence: "The company is in debt and has been unable to pay its creditors for the past six months."

Additional Information

 Difference between "its" and "it's":

• "Its" is a possessive pronoun, indicating ownership or possession.
• Example: The company announced its new product.
• "It's" is a contraction of "it is" or "it has."
• Example: It's raining outside.

The correct answer is "Option 1".

Key Points

• The erroneous part is "knows".
• The subject of the sentence is "Everybody," which is a singular pronoun, So the verb should also be in singular form to agree with the subject.
• The correct verb form to use with a singular subject is "knows" instead of "know."
• Hence, the erroneous part is "knows".

Therefore, the correct answer is "Option 1".

Correct Sentence:  "Everybody knows that his failure can be attributed only to his lack of practice."

Additional Information

• "Each", "every", "either", and "neither" is used with a singular noun.
• Example: Each child was given a balloon.

• After understanding the meanings of the marked words, we can conclude that the word "subscriber" should be interchanged with "telecom" to make the sentence grammatically and contextually correct because it is the telecom operators that provide services to subscribers, not the other way around.
• Hence, the correct answer is "C-D."

The correct sentence after the rearrangement would be: "A policy framework is needed to ensure equitable contributions from major OTT service providers to telecom operators, determined by factors such as subscriber count and data usage."

The correct answer is option 4.

• Similarly, "professional" should be interchanged with "transformative" to convey that the era is characterized by significant changes rather than emphasizing a focus on professionalism.
• Hence, the correct answer is "B-C, D-A."

The correct sentence after the rearrangement would be: "In this era of transformative change, the growing presence of generative AI in the workplace presents challenges, but people are embracing the positive impact it can have on their professional lives."

​

Key Points

• Context: The given sentence says that they woke up when someone was hammering on the surface of the door. So, to give this sentence a meaningful sense we need to replace the preposition 'below' with 'on'.
• The meaning of the preposition 'On' is 'on a surface of something', here, something is the door.
• Example- The book is on the table.
• Hence, the correct answer would be option 2 i.e. on the table.
• Let’s see the meaning of other prepositions given in the option:
• ​Here the prepositions 'at' 'in' 'on' denote place. But we need to understand their difference.
• 'At' is used to denote a point.
• E.g. She is at her home.
• 'In' is used to denote a larger place like country or city.
• E.g. I live in London.
• Below is used to denote a lower position (than), under
• E.g. From the top of the skyscraper the cars below us looked like insects.

So the right answer is option 3 as 'on' is denoting 'on a surface of something.'

The correct answer is option 5.

Key Points

• We use affect as a verb only and effect as both verb and noun.
• Based on the structure, of the sentence, we need a verb, and hence, affect will be more appropriate.
• Affect means to influence something or someone.
• Effect, when used as a noun, means the result of an influence and when used as a verb, effect means to bring about or cause something to occur.
• Examples –
• The harmful effects of drugs should be highlighted. (effect as noun)
• The breakup has affected him severely.
• The government was not able to effect any change. (effect as a verb - meaning the government was not able to bring about any change)
• The subject of the sentence is ‘every second child’ which is singular in nature.
• So, we should use is affected and not are affected.  

Hence, the given sentence is grammatically correct and logically sound.

Shortcut Trick

Speed in still water (u) = 16 km/h, Speed of current (v) = 4 km/h.

Downstream speed (D) = u + v = 16 + 4 = 20 km/h.

Upstream speed (U) = u − v = 16 − 4 = 12 km/h.

Average Speed for a round trip = [2 × D × U] ÷ [D + U] = [2 × 20 × 12] ÷ [20 + 12] = 480 ÷ 32 = 15 km/h.

∴ The correct answer is 15 km/h.

Alternate Method

Given:

Speed of Suraj in still water (u) = 16 km/h

Speed of current (v) = 4 km/h

Formula Used:

Downstream Speed = u + v

Upstream Speed = u − v

Average Speed = (Total Distance) ÷ (Total Time)

Calculations:

⇒ Downstream Speed (D) = 16 + 4 = 20 km/h

⇒ Upstream Speed (U) = 16 − 4 = 12 km/h

⇒ Let the distance for one way be 'd' km.

⇒ Total distance = d + d = 2d

⇒ Total time = (d ÷ 20) + (d ÷ 12) = (3d + 5d) ÷ 60 = 8d ÷ 60

⇒ Average speed = 2d ÷ (8d ÷ 60) = (2d × 60) ÷ 8d = 120 ÷ 8

⇒ Average speed = 15 km/h

∴ The correct answer is 15 km/h.

Additional Information

Downstream and Upstream Speed

Downstream speed is the sum of speed in still water and stream speed (u+v), while upstream is the difference (u−v).

Average Speed for Constant Distance

When distances are equal, Average Speed = (2 × x × y) ÷ (x + y), where x and y are the speeds for the two parts.

Speed in Still Water from D and U

Speed in still water (u) = (Downstream speed + Upstream speed) ÷ 2.

Current Speed from D and U

Current speed (v) = (Downstream speed − Upstream speed) ÷ 2.

Shortcut Trick

Let Shreya's present age be 7 units based on the given ratio.

Then, Raghav's age 8 years hence = 17 units.

Pavan's present age = 3 × Shreya = 21 units.

Difference between Pavan and Raghav: (21 units) − (17 units − 8) = 12 years.

⇒ 4 units + 8 = 12 ⇒ 4 units = 4 ⇒ 1 unit = 1 year.

Pavan's present age = 21 × 1 = 21 years.

Pavan's age 3 years hence = 21 + 3 = 24 years.

∴ The correct answer is 24 yrs.

2. (R + 8) ÷ S = 17 ÷ 7
3. P = 3S

Calculations:

⇒ From (3), S = P ÷ 3

⇒ From (1), R = P − 12

⇒ Substitute R and S in (2):

⇒ ((P − 12) + 8) ÷ (P ÷ 3) = 17 ÷ 7

⇒ (P − 4) ÷ (P ÷ 3) = 17 ÷ 7

⇒ 3 × (P − 4) ÷ P = 17 ÷ 7

⇒ 21 × (P − 4) = 17P

⇒ 21P − 84 = 17P

⇒ 4P = 84

⇒ P = 21 years (Present age)

⇒ Age after 3 years = 21 + 3 = 24 years

∴ The correct answer is 24 yrs.

Additional Information

Ratio and Proportion in Ages

When the ratio of ages at different time intervals is given, always equate the constant difference or express all variables in terms of a single variable.

Age Difference Property

The difference between the ages of two persons remains constant throughout their lives, regardless of the number of years passed.

Future and Past Ages

If present age is 'x', age 'n' years hence is (x + n) and age 'n' years ago was (x − n).

Shortcut Trick

For 2 years, the difference between CI and SI is the interest earned on the first year SI.

SI for 1 year = 2700 ÷ 2 = ₹1350.

Difference (CI − SI) = 2781 − 2700 = ₹81.

Rate of Interest = (Difference ÷ 1^st Year SI) × 100 = (81 ÷ 1350) × 100 = 6%.

∴ The correct answer is 6%.

Alternate Method

Given:

Simple Interest (SI) for 2 years = ₹2,700

Compound Interest (CI) for 2 years = ₹2,781

Time (T) = 2 years

Calculations:

⇒ SI for 1 year = 2700 ÷ 2 = ₹1,350

⇒ Difference (D) = CI − SI = 2781 − 2700 = ₹81

⇒ This difference ₹81 is the interest calculated on the first year's interest (₹1,350) for 1 year.

⇒ Rate (R) = (D × 100) ÷ (SI for 1 year × 1)

⇒ R = (81 × 100) ÷ 1350

⇒ R = 8100 ÷ 1350 = 6%

∴ The correct answer is 6%.

Additional Information

Relation between CI and SI for 2 years

The ratio of Compound Interest to Simple Interest for 2 years is given by the formula: CI / SI = (200 + R) / 200.

Difference formula for 2 years

The difference (D) between CI and SI for 2 years is D = P × (R/100)².

Compound Interest Basics

For the first year (if compounded annually), Simple Interest and Compound Interest are always equal.

Shortcut Trick

The ratio of Profit Share is equal to the ratio of Investment when the time period is the same for all partners.

Ratio of Capitals (Ram : Lakhan : Bharat) = 85000 : 68000 : 34000 = 85 : 68 : 34 = 5 : 4 : 2.

Total ratio units = 5 + 4 + 2 = 11 units. Total Profit = Rs. 13,310.

Value of 1 unit = 13310 ÷ 11 = Rs. 1,210.

Difference between Ram and Bharat = (5 − 2) units = 3 units.

Difference in Profit = 3 × 1210 = Rs. 3,630.

∴ The correct answer is Rs. 3,630.

Alternate Method

Given: Ram's Capital = Rs. 85,000, Lakhan's Capital = Rs. 68,000, Bharat's Capital = Rs. 34,000. Total Profit = Rs. 13,310. Time = 5 years (constant).

Formula: Profit Ratio = (C₁ × T₁) : (C₂ × T₂) : (C₃ × T₃)

⇒ Ratio of Profit = (85000 × 5) : (68000 × 5) : (34000 × 5)

⇒ Ratio of Profit = 85 : 68 : 34 = 5 : 4 : 2

⇒ Let Ram's share = 5x, Lakhan's = 4x, Bharat's = 2x

⇒ 5x + 4x + 2x = 13310 ⇒ 11x = 13310 ⇒ x = 1210

⇒ Difference (Ram − Bharat) = 5x − 2x = 3x

⇒ 3 × 1210 = 3630

∴ The correct answer is Rs. 3,630.

Additional Information

Partnership Basics

In a partnership, profit is distributed based on the product of Investment and Time. If time is constant, profit depends solely on the investment ratio.

Simple vs Compound Partnership

A Simple Partnership involves investments for the same duration, while a Compound Partnership involves investments for different time periods.

Solution:

Number of projects completed in January = 120

Number of projects completed in March = 70

Required percentage = 120/70 ×  100 = (171.14 - 100) ~ 71%

∴ The total number of projects completed in January is approximately 71% more than the total number of projects completed in March.

Solution:

Number of projects completed by company A in January = 120

Number of projects completed by company B in February = 120 ×  150/100 = 180

Number of projects completed by company B in March = 255 - 180 = 75

Required difference = (180 - 75) = 105

Solution:

Number of projects completed in May = 100

Number of projects completed in January and June = (120 + 130) = 250 

Required ratio = 100: 250 = 2: 5

Solution:

Number of projects completed in May = 100

Number of projects completed in January = 120

Number of projects completed in December = 115 ×  3 - (100 + 120) = 125

Number of projects completed in February = 110

Required percentage = 110/125 ×  100 = 88%

Solution:

Number of projects completed in March = 70

Number of projects completed in June = 130

Total number of projects completed in August = 2 ×  (130 - 70) = 120

Number of projects completed in April = 140

Number of projects completed in July = 140/7 ×  5 = 100

Required sum = (120 + 100) = 220

Shortcut Trick

Ratio of Amount (A) to Principal (P) is 19600 : 10000 = 196 : 100.

Rate is 40%, so the Multiplier is (1 + 40/100) = 1.4 or 14/10.

Check the power: (14/10)² = 196/100.

Since the power is 2, the Time Period is 2 years.

∴ The correct answer is 2 years.

Alternate Method

Given: Principal (P) = ₹ 10,000, Amount (A) = ₹ 19,600, Rate (R) = 40% p.a.

Formula Used: A = P(1 + R/100)ⁿ

⇒ 19600 = 10000(1 + 40/100)ⁿ

⇒ 19600 / 10000 = (140 / 100)ⁿ

⇒ 196 / 100 = (1.4)ⁿ

⇒ (1.4)² = (1.4)ⁿ

⇒ n = 2

∴ The correct answer is 2 years.

Additional Information

Compound Interest (CI) Formula

Interest is calculated on the initial principal and also on the accumulated interest of previous periods: CI = A − P.

Half-yearly Compounding

If interest is compounded half-yearly, the rate is halved (R/2) and the time is doubled (2n) in the formula.

Rule of 72

A quick way to estimate the time required to double an investment: Time ≈ 72 ÷ Interest Rate.

Shortcut Trick

Use the weighted average method based on parts of the land.

Let the total parts be 5. Loss is taken as negative and profit as positive.

Total Profit = (Part 1 × P/L%) + (Part 2 × P/L%)

15% × 5 = (3 × −5%) + (2 × x%)

75 = −15 + 2x ⇒ 2x = 90 ⇒ x = 45%.

∴ The correct answer is 45%.

Alternate Method

Given: Total CP = Rs. 45,000, Loss on 3/5 part = 5%, Total Profit required = 15%.

Formulas: SP = CP × (100 ± P/L)% / 100 | Profit = SP − CP.

⇒ Total required SP = 45000 × (115/100) = Rs. 51,750.

⇒ CP of 3/5 part = 45000 × (3/5) = Rs. 27,000.

⇒ SP of 3/5 part (at 5% loss) = 27000 × (95/100) = Rs. 25,650.

⇒ Required SP for remaining part = 51750 − 25650 = Rs. 26,100.

⇒ CP of remaining 2/5 part = 45000 × (2/5) = Rs. 18,000.

⇒ Profit on remaining part = 26100 − 18000 = Rs. 8,100.

⇒ Profit % = (8100 / 18000) × 100 = 45%.

∴ The correct answer is 45%.

Additional Information

Weighted Average in Profit & Loss

When different portions of a single quantity are sold at different profit/loss percentages, the overall profit/loss percentage is the weighted average of individual percentages.

Independent of Actual Value

If the question asks for the percentage profit or loss, the actual price (like Rs. 45000) does not affect the final result; only the ratio of parts matters.
