The correct answer is option 4), i.e., 'growth.'

Key Points

• Let's look at the meaning of the words given in the options:

• The context of the sentence is that the country's quick development has raised the standard of living for many people.
• According to the above-mentioned points, the most appropriate word to fill in the blank is "growth."
• Therefore, the correct answer is Option 4.
• Another example:
• Calcium is good to the growth of your bones.

Complete Sentence: The country's rapid growth has led to a rise in many people's standard of living.

The correct answer "C" 

Key Points

• The error lies in part 'C' of the sentence because 'unless' is used instead of 'until'.
• The sentence is expressing that the teacher informed the class that the exam would be postponed until next week.
• 'Until' is used to indicate that something will happen after a certain point in time, whereas 'unless' is used to indicate that something will happen only if a certain condition is met.
• Hence, 'until' must be used instead of 'unless' to make the sentence correct.

Thus, option 1 is the correct answer.

Correct Sentence: The teacher informed the class that the exam would be postponed until next week.

The correct answer is: ​The ability to see through things or perceive hidden details.

Key Points

• The idiom "X-ray vision" is often used humorously or metaphorically to describe the ability to see through objects or perceive things that are not immediately apparent.
• It implies a heightened or extraordinary level of insight or perception.
• Example: Jane has a knack for understanding people's emotions even when they don't express them outwardly. It's as if she has X-ray vision into their feelings and thoughts.

​Therefore, the correct answer is option 4.

The correct answer is "Atheist"

Key Points

• Let's understand the meaning of the given one words.
• Theist: A person who believes in the existence of one or more gods or deities.(आस्तिक)
• For example, "John is a devout theist and regularly attends church services."
• Idolizer: A person who admires and reveres someone or something excessively(मूर्तिपूजक).
• For example, "Sara is an idolizer of her favorite pop star and has all their merchandise."
• Atheist: A person who does not believe in the existence of gods or deities.(नास्तिक)
• For example, "Jane is an atheist and does not believe in any kind of supernatural power."
• Deist: A person who believes in the existence of a god or supreme being, but denies revealed religion and bases this belief solely on reason or natural laws.(आस्तिक)
• For example, "Tom is a deist, he believes in a higher power, but not in religious doctrines."
• Thus, as per the above explanation the correct one word is "Atheist"

The correct answer is '​A huge notice warned us to beware of pickpockets.'

Key Points 

• The reporting verb 'said/said to' is changed in 'asked, demanded, ordered, enquired, offered' as per the nature of the sentence.
• The first person in reported speech changes according to the subject of reporting speech.
• In Reported Speech change of the second person depends on the object of reporting speech.
• The third person remains unchanged.
• Imperative sentences do not normally have an expressed subject.
• This is because the subject ‘you’ is usually understood.
• As a result of this, imperative sentences begin with a verb in the simple present tense.
• In order to change an imperative sentence into indirect speech, we use a to-infinitive.
• Example: 
• The old woman said to the boy, ‘Please help me.’
• The old woman requested the boy to help her.
• Therefore, the correct answer is Option 3.
  

Correct sentence: A huge notice warned us to beware of pickpockets.

The correct answer is 'A person who thinks he is of a high social class and looks down on people of lower class'.

Key Points

• The idiom "toffee-nosed" is used to describe someone who is snobbish or conceited, particularly regarding their perceived social status or class superiority.
• It implies an attitude of superiority and looking down on others.
• In the given sentence, Mr. Avinash's brother is described as "toffee-nosed," suggesting that he behaves in a snobbish or condescending manner, possibly due to considering himself of a higher social class than others.
• Option 1 best captures this meaning, as it directly correlates with the behavior described in the sentence.

Therefore, the correct answer is 'option 1'.

Additional Information

• Option 2 is inappropriate and not suitable.
• Option 3 is inappropriate and not suitable.
• Option 4 is inappropriate and not suitable.

The correct answer is 2) Neutral.

Key Points

• “Fundamental” refers to something basic, core, or essential in nature.
• In contrast, “neutral” implies absence of a defining, essential, or foundational position; it denotes something that is neither basic nor aligned with core principles.
• Hence, 'neutral' is taken as the most appropriate antonym here.

Additional Information

Why others are incorrect:

• Impact – denotes effect or influence, not opposition to “fundamental.”
• Least – refers to quantity or degree, not to essential nature.
• Link – means connection or association.

The erroneously spelt word is "Spontanous"

Key Points 

• The correct spelling is Spontaneous.
• Let's look at the meaning of the word:
• Spontaneous- performed or occurring as a result of a sudden impulse or inclination.
• Example: The reaction of Lithium with water is always spontaneous.

Hence, the correct answer is "option 1".

Additional Information

• Let's look at the meanings of the other words:
• Pilgrimage- a pilgrim's journey.
• Temperament- a person's or animal's nature
• Enormous- very huge in size

• Spontaneous- तेज़ी से होना .
• Example: The reaction of Lithium with water is always spontaneous.

• Enormous- विशाल

The correct answer is 'obscure'.

Key Points

• Apparent means clearly visible or understood; obvious. (स्पष्ट)
• Example: The reason for his happiness was apparent when he received the award.
• Obscure refers to something not discovered or known about; uncertain or unclear. (अस्पष्ट)
• Example: The origins of the ancient manuscript remain obscure, with little evidence to pinpoint its exact time period.
• Hence, the correct antonym is Obscure.

Therefore, the correct answer is "Option 3".

Additional Information

• Probable means likely to happen or be the case. (संभावित)
• Example: The dark clouds made rain probable later in the day.
• Manifest means clear or obvious to the eye or mind. (प्रकट)
• Example: His nervousness was manifest in his shaky hands.
• Obvious means easily perceived or understood; clear, self-evident, or apparent. (स्पष्ट)
• Example: The solution to the problem was obvious once he stopped overthinking it.

The correct answer is option 1), i.e., 'Feasible.'

Key Points 

• Let's look at the meaning of the marked option:
• Feasible - capable of being done, effected, or accomplished. (संभव)
• Example:
• Your new business proposal sounds quite feasible.
• ​Let's look at the meanings of the other given options:​
• Untenable - not able to be maintained or defended against attack or objection. (असमर्थ, अस्थिर)
• Irrevocable - not able to be changed, reversed, or recovered; final. (अपरिवर्तनीय)
• Eligible - having the right to do or obtain something; satisfying the appropriate conditions. (योग्य)
• Hence, from the given meanings, we find that 'Feasible' is the correct one-word substitute.
• So, the correct answer is option 1.

The correct answer is "Oliver told his teacher that she had taken his notebook."

Key Points

• The reporting verb "said" is changed to "told" in reported speech if there is a personal object.
• The pronoun "she" and the possessive "my" remain the same because these refer to people other than the speaker and the listener (Oliver and his teacher).
• Conjunction "that" will be used instead of inverted commas.
• The verb form "had taken" is already in the past perfect tense, which typically remains unchanged in reported speech.

Therefore, the correct answer is "Option 3".

The correct answer is option 4) i.e. "ACDB." 

Key Points

• In the abovementioned paragraph, there is a chronological sequence of the sentences.
• Sentence A is the first sentence as it begins with the noun 'Shalini' and mentions as she awaited her friend, she was scrolling through the phone's screen.
• Sentence C is the second sentence as it begins with the conjunction 'when' and mentions the next incident which is after her friends arrival, they went to the market. Thus it establishes a relation with the previous sentence.
• Sentence D is the third sentence as it begins with the noun 'The market place' and creates a relevent situation that is the condition of the market.
• The only option that shows such an arrangement is Option 4.
• Sentence B is the last sentence as it begins with the pronoun 'her' and mentions what they did in the market. Thus, it establishes a relation with the previous sentence.
• Thus, the correct answer is Option 4.

The correct answer is 'a'.

Key Points

• The indefinite article "a" is used before singular nouns that are not specific.
• In this sentence, "graduate" is a singular noun referring to any graduate in general, not a specific one.
• The sentence does not mention a particular graduate, so we cannot use the definite article "the".
• "An" is not used before words that begin with a consonant sound, and "graduate" begins with a consonant sound /g/.

Therefore, the correct answer is 'Option 1'.

Complete Sentence: You have to be a graduate to attend this course.

Additional Information

• Option 2) an is incorrect because "graduate" begins with a consonant sound /g/.

The correct answer is 'break in a career'.

Key Points

• The passage discusses the challenges women face regarding their careers after becoming mothers. It highlights how the responsibilities of motherhood often lead to women having to choose between their careers and their roles as mothers.
• In this context, the term 'hiatus' refers to a pause or interruption in a woman's career trajectory due to the demands and responsibilities of motherhood.
• The passage emphasizes the impact of this hiatus on women, stating that a long break from work can have detrimental effects on a woman's individuality, self-esteem, and sense of purpose. It mentions the risk of depression that can arise when a woman faces an extended period away from her career.
• The reason 'break in a career' is the correct interpretation of 'hiatus' in this context is because the passage discusses how women, after childbirth, often find themselves having to temporarily leave or interrupt their careers to focus on their role as mothers.
• This interruption or break is the hiatus referred to in the passage, highlighting the challenges and consequences associated with it.

The correct answer is 'The empowered women'.

Key Points

• The passage delves into the challenges women face in balancing motherhood with their careers. It discusses how both empowered and unempowered women encounter difficulties when dealing with the impact of motherhood on their professional lives. However, it suggests that the empowered women, despite facing obstacles, are generally better equipped to navigate these challenges compared to their unempowered counterparts.
• The passage mentions that the empowered group possesses financial, ideological, and emotional resources that enable them to potentially recreate their careers after a hiatus due to motherhood. While they may still face frustration and identity crises, they have a better chance of rebuilding their careers compared to the unempowered women.
• Conversely, the unempowered women, lacking similar resources and support, often find themselves caught between the responsibilities of motherhood and a slipping career. Their struggle to balance these roles is portrayed as more challenging, with fewer opportunities to regain or reconstruct their careers after a hiatus.
• Therefore, the correct answer is: The empowered women.

The correct answer is 'Many decide to adopt babies'.

Key Points

• The passage extensively discusses the challenges and choices working women face when dealing with motherhood and their careers. It covers various scenarios, such as some women rejecting motherhood entirely, others delaying childbirth until later stages of their lives, and the struggle many face in balancing their careers with the responsibilities of being a mother.
• However, the passage does not address the specific choice of women deciding to adopt babies. Adoption as an alternative to biological childbirth is not explicitly mentioned in the passage's discussion about the impact of motherhood on women's careers and the choices they make.
• The line in the passage that aligns with the options mentioned is: "Others delay child-bearing for so long that they are forced into the arms of the booming fertility industry." This line highlights the choice of delaying motherhood, which corresponds to option D, but there is no mention of the choice of adoption among working women.

The correct answer is 'A woman sacrificing her individuality on becoming a mother.'

Key Points

• The phrase "slaying her own sphere bit by bit" in the passage refers to the process where a woman gradually sacrifices or compromises her own domain or personal space, likely due to the demands and responsibilities of motherhood.
• The correct interpretation is: 'A woman sacrificing her individuality on becoming a mother.'
• In the passage, the line that relates to this phrase is: "Conventionally, a mother is seen putting others before herself. She is known for slaying her own sphere bit by bit to build a new world for her child."
• This line suggests the traditional societal expectation that mothers prioritize their children and family above their own needs or individuality, gradually sacrificing their personal space or individual pursuits for the sake of nurturing and building a world for their children.

The correct answer is 'the responsibilities on becoming a mother'.

Key Points

• The phrase "The former takes precedence for many" implies that among the various aspects of a woman's life, the responsibilities that arise upon becoming a mother are given higher priority or importance by many individuals.
• This phrase suggests that, for a significant number of women, the duties and obligations linked to motherhood become the primary focus or take precedence over other facets such as personal ambitions, career pursuits, or other sacrifices they might have made before becoming mothers.
• The passage discusses the challenge many women face when they transition into motherhood and are compelled to choose between their thriving careers and the responsibilities that come with raising a child.
• This phrase underscores the prevalence of a choice where, for a considerable number of women, the responsibilities tied to motherhood become the priority over other aspects of their lives.

The correct answer is Agriculture.

Key Points

• Before India's independence, agriculture was the predominant sector contributing to the national income. The Indian economy was primarily agrarian in nature, with a majority of the population engaged in farming and related activities.
• The British colonial policies led to the exploitation of Indian agriculture, which was mainly subsistence-based. Despite this, agriculture remained the backbone of the economy, contributing to over 50% of the national income.
• Industries and services such as trade, transport, and banking were underdeveloped and contributed only a small fraction to the national income. Hence, agriculture was the dominant sector in the economy.
• The majority of the population, approximately 70-80%, depended on agriculture for their livelihood. This dependence on agriculture was due to the lack of industrialization and minimal focus on other economic sectors.
• The agricultural sector faced significant issues such as low productivity, outdated techniques, and excessive taxation. Despite these challenges, it remained the primary source of income and employment. Hence, agriculture was the dominant sector before independence.

Additional Information

• Agriculture in Pre-Independence India:
• Agriculture was the largest contributor to the economy, but it was heavily exploited under British rule. The Permanent Settlement Act of 1793 introduced the zamindari system, which burdened farmers with heavy taxes.
• The focus of British policies was on maximizing revenue rather than improving agricultural productivity. This resulted in periodic famines and economic distress for farmers.
• The introduction of cash crops such as cotton, indigo, and opium for export further impacted food grain production. This shift prioritized British economic interests over local needs.
• Other Economic Sectors before Independence:
• Industry: The industrial sector was underdeveloped and consisted mainly of small-scale industries such as textiles and handicrafts. The deindustrialization caused by British policies led to the decline of traditional industries.
• Trade and Transport: Trade was primarily focused on exporting raw materials to Britain and importing finished goods. The development of railways was aimed at facilitating this trade rather than fostering domestic growth.
• Banking: The banking sector was limited and served primarily British economic interests. Indian-owned banks were few and had a minimal role in the economy.

Important Points

• Key Features of Agriculture Before Independence:
• The agricultural sector was characterized by subsistence farming, with farmers using traditional methods and tools.
• The Green Revolution and advancements in agriculture took place much later, post-independence, to improve productivity and reduce dependency on imports.
• The exploitation of farmers through heavy land taxes, low remuneration for crops, and lack of irrigation facilities were major issues.
• Contribution of Other Sectors:
• The industrial sector contributed minimally to the economy due to the lack of investment and infrastructure.
• The services sector, including banking and transport, remained underdeveloped and served colonial interests rather than the local economy.

• The Swaran Singh Committee was constituted by the Indira Gandhi government in 1976 to make recommendations about Fundamental Duties, the necessity of which was felt during the internal emergency (1975−1977).
• The committee suggested that a separate chapter on Fundamental Duties should be included in the Constitution to ensure that citizens are conscious of their duties while enjoying their Fundamental Rights.
• Based on these recommendations, the 42nd Constitutional Amendment Act was enacted in 1976, which added a new Part IVA and Article 51A to the Indian Constitution.
• Initially, the committee recommended the inclusion of eight Fundamental Duties, but the 42nd Amendment actually incorporated ten duties.
• The 11th Fundamental Duty, which pertains to providing opportunities for education to children between 6 and 14 years, was added later via the 86th Constitutional Amendment Act in 2002.

 Additional Information

• Sarkaria Commission:
• Set up in 1983 to examine the relationship and balance of power between the Central and State governments.
• Verma Committee:
• Established in 1999 to identify the existence of legal provisions for the implementation of Fundamental Duties and to suggest a strategy for teaching them in schools.
• Balwant Rai Mehta Committee:
• Appointed in 1957 to examine the Community Development Programme; it is famous for recommending a three-tier Panchayati Raj system in India.
• Fundamental Duties in the Indian Constitution were inspired by the Constitution of the USSR and are non-justiciable in nature.

The correct answer is Amend Fundamental Rights.

Key Points

• The 24th Constitutional Amendment Act was enacted in the year 1971 during the tenure of Prime Minister Indira Gandhi. This amendment was primarily brought to nullify the effect of the Supreme Court judgment in the Golaknath case (1967).
• It amended Article 13 and Article 368 of the Constitution of India to affirm that Parliament has the absolute power to amend any part of the Constitution, including Fundamental Rights listed in Part III. Hence, option A is correct.
• The amendment clarified that Article 13, which states that any law inconsistent with Fundamental Rights shall be void, would not apply to any constitutional amendment made under Article 368.
• Prior to this, the Supreme Court in the Golaknath case had ruled that Parliament could not abridge or take away any of the Fundamental Rights through a constitutional amendment.
• The power to suspend High Court judgments or bypass judicial proceedings is not a feature of the 24th Amendment; such issues were more relevant to the 42nd Amendment or specific emergency provisions. Hence, option B is incorrect.
• While the amendment sought to limit the scope of Judicial Review over constitutional changes, it did not entirely "override" the concept of judicial review, which was later protected as a part of the Basic Structure. Hence, option C is incorrect.
• The 24th Amendment does not deal with the suspension of elections, which is governed by the Representation of the People Act and Emergency provisions of the Constitution. Hence, option D is incorrect.

Additional Information

• Article 368: This article provides the Parliament with the constituent power to amend the Constitution by way of addition, variation, or repeal of any provision according to the procedure laid down therein.
• President's Assent: The 24th Amendment made it mandatory for the President of India to give his assent to a Constitution Amendment Bill. Before this, the President had the discretion to withhold assent or return the bill.
• Golaknath v. State of Punjab (1967): In this landmark 6:5 majority judgment, the Supreme Court held that Fundamental Rights are "transcendental" and "immutable," meaning Parliament has no power to amend them. This created a legal deadlock that the 24th Amendment resolved.
• Article 13: It originally acted as a shield for Fundamental Rights, declaring that any "law" made by the state that takes away these rights is void. The 24th Amendment added a clause stating that "nothing in this article shall apply to any amendment of this Constitution made under Article 368."
• Legislative Supremacy: This amendment represented a period of intense conflict between the Judiciary and the Legislature in India, where the government sought to establish the supremacy of Parliament in matters of social and economic reform.

Important Points

• Kesavananda Bharati Case (1973): The validity of the 24th Amendment was challenged in this famous case. The Supreme Court upheld the amendment but introduced the Basic Structure Doctrine, stating that while Parliament can amend any part of the Constitution, it cannot alter its "basic structure" or "essential features."
• Fundamental Rights vs. DPSP: The 24th Amendment was a precursor to the 25th Amendment, which sought to give Directive Principles of State Policy (DPSP) precedence over Fundamental Rights in certain cases (specifically Articles 39(b) and 39(c)).
• Constitutional Balance: Today, the power of Parliament to amend the Constitution is widely accepted, provided it respects the core values like Secularism, Democracy, Federalism, and Judicial Review as established by the 13-judge bench in 1973.
• The amendment effectively changed the status of Fundamental Rights from being unalterable to being amendable, ensuring that the Constitution remains a living document capable of adapting to the changing needs of the Indian people.

Important Points 

The correct answer is Fiscal deficit.

Key Points

• Fiscal Deficit:
• Excess of Expenditure over Revenue: The fiscal deficit is the difference between the government's total expenditure (including capital expenditure) and its total revenue (excluding borrowings). It indicates the total borrowing requirements of the government.
• Financing the Gap: This deficit is financed through borrowing, either from the domestic market or from abroad.
• Impact on Debt: A persistent high fiscal deficit can lead to an increase in the government's debt burden.
• Economic Implications: It can have implications for interest rates, inflation, and overall economic stability. A large and unsustainable fiscal deficit can crowd out private investment.
• Policy Tool: Governments often use fiscal policy, including managing the fiscal deficit, to influence the economy. However, excessive deficits can raise concerns about long-term sustainability.

Additional Information

• Revenue Deficit:
• Current Expenditure vs. Current Revenue: The revenue deficit is the difference between the government's revenue expenditure (day-to-day running expenses) and its revenue receipts (tax and non-tax revenues).
• Indicates Fiscal Imbalance: A revenue deficit implies that the government is spending more on its day-to-day operations than it earns in current revenue. This is generally considered less sustainable than a fiscal deficit driven by capital expenditure.
• Need for Borrowing: A revenue deficit often necessitates borrowing just to meet consumption expenditure, which can be detrimental to long-term fiscal health.
• Impact on Development: A high revenue deficit can squeeze resources available for development expenditure (investments in infrastructure, education, etc.).
• Measure of Efficiency: It can be an indicator of the government's efficiency in managing its revenue and expenditure.
• Capital Deficit:
• Not a Standard Term: "Capital deficit" is not a commonly used term in economics. The more relevant concept is capital expenditure, which refers to government spending on long-term assets like infrastructure, buildings, and equipment.
• Capital Expenditure and Growth: Capital expenditure is considered crucial for economic growth and development.
• Financing Capital Projects: Governments finance capital expenditure through a combination of revenue, borrowings, and sometimes disinvestment.
• Budgetary Planning: Capital expenditure is a key component of the government's budget and is often part of long-term development plans.
• Impact on Future: Investments made through capital expenditure have long-term impacts on the economy's productive capacity.
• Current Account Deficit (CAD):
• Balance of Payments: The current account deficit is a measure of a country's balance of payments. It reflects the difference between a country's total exports of goods, services, and transfers and its total imports of goods, services, and transfers.
• Trade Deficit: A major component of the CAD is the trade deficit, which occurs when a country imports more goods and services than it exports.
• Other Components: The current account also includes income from investments (interest, dividends) and current transfers (aid, remittances).
• Financing the CAD: A CAD can be financed through foreign investment, borrowing, or by using foreign exchange reserves.
• Economic Implications: A large and persistent CAD can raise concerns about a country's external debt and its ability to meet its international obligations. It can also put pressure on the exchange rate.

Shortcut Trick

Rani present age = 25 − 5 = 20 years.

Rani : Vani = 4 : 5

4 parts = 20 years ⇒ 1 part = 5 years.

Vani present age = 5 parts = 5 × 5 = 25 years.

∴ The correct answer is 25 years.

Alternate Method

Given:

Ratio of Rani age to Vani age = 4 : 5

Rani age after 5 years = 25 years

Formula Used:

Age after n years = Present age + n

Rani (4x)

Vani (5x)

• 5 years = 25 Present Age Ratio → 4 : 5

Let the present age of Rani be 4x and Vani be 5x.

⇒ Rani age after 5 years = 4x + 5

⇒ 4x + 5 = 25

⇒ 4x = 25 − 5

⇒ 4x = 20

⇒ x = 20 ÷ 4 = 5

⇒ Vani present age = 5x

⇒ Vani present age = 5 × 5 = 25 years

∴ The correct answer is 25 years.

Additional Information

Concept of Age Ratio

If the ratio of ages of A and B is a : b, their ages can be assumed as ax and bx where x is a common constant.

Constant Difference

The difference between the ages of two individuals remains constant regardless of the number of years passed or preceding.

Future and Past Ages

To find the age 'n' years ago, we subtract 'n' from the present age. To find the age after 'n' years, we add 'n' to the present age.

Shortcut Trick

Speed is constant, so Distance is directly proportional to Time.

Time to cross man (Train length) = 12 seconds → 240 m

Time to cross bridge (Train + Bridge) = 40 seconds → (240 / 12) × 40 = 800 m

Length of Bridge = Total Distance − Train Length = 800 − 240 = 560 m.

∴ The correct answer is 560 m.

Alternate Method

Given: Length of Darjeeling mail = 240 m, Time to cross man = 12 s, Time to cross bridge = 40 s.

Formula Used: Speed = Distance ÷ Time

⇒ Speed of train = Length of train ÷ Time to cross man

⇒ Speed = 240 ÷ 12 = 20 m/s

⇒ While crossing bridge, Distance = Length of train + Length of bridge (L)

⇒ 20 = (240 + L) ÷ 40

⇒ 800 = 240 + L

⇒ L = 800 − 240 = 560 m

∴ The correct answer is 560 m.

Additional Information

Relative Speed

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

Unit Conversion

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

Train Crossing Concepts

When a train crosses a pole/man, distance = length of train. When it crosses a platform/bridge, distance = length of train + length of object.

Given:

15 feet, 12 feet 9 inches, 16 feet 3 inches, 23 feet 6 inches

Concept:

We'll use the concept of Highest Common Factor (HCF) to solve this problem as the greatest possible length of scale to measure all these lengths exactly will be the HCF of

these measurements.

Calculation:

First, convert all the measurements to the same units. Here we'll convert everything to inches. 1 foot = 12 inches.

15 feet = 15 × 12 = 180 inches

12 feet 9 inches = 12 × 12 + 9 = 153 inches

16 feet 3 inches = 16 × 12 + 3 = 195 inches

23 feet 6 inches = 23 × 12 + 6 = 282 inches

⇒ The numbers to find HCF are 180, 153, 195, and 282.

⇒ The HCF of these numbers is 3 inches.

Hence, the greatest possible length of the scale to measure all these lengths exactly is 3 inches.

Given:

12 - [24 - (72 ÷ 3 - (30 - 50 ÷ 5) ÷ 20)]

Concept used:

Follow the BODMAS rule according to the table given below:

Calculation:

⇒ 12 - [24 - (72 ÷ 3 - (30 - 50 ÷ 5) ÷ 20)]

⇒ 12 - [24 - (72 ÷ 3 - (30 - 10) ÷ 20)]

⇒ 12 - [24 - (72 ÷ 3 - 20 ÷ 20)]

⇒ 12 - [24 - (24 - 1)]

⇒ 12 - [24 - 24 + 1]

⇒ 12 - 1

⇒ 11

∴ Option 1 is the correct answer.

Shortcut Trick

Distance 1 = (2/5) × 900 = 360 km

Time 1 = 360 ÷ 60 = 6 hours

Remaining Distance = 900 − 360 = 540 km

Remaining Time = 11 − 6 = 5 hours

Required Speed = 540 ÷ 5 = 108 km/h

∴ The correct answer is 108 km/h.

Alternate Method

Given: Total Distance = 900 km, Total Time = 11 h, Speed₁ = 60 km/h, Distance₁ = 2/5 of Total.

Formula Used: Speed = Distance ÷ Time | Time = Distance ÷ Speed

⇒ Distance of first part = 900 × (2/5) = 360 km

⇒ Time taken for first part = 360 ÷ 60 = 6 hours

⇒ Remaining distance = 900 − 360 = 540 km

⇒ Remaining time = 11 − 6 = 5 hours

⇒ Required speed for remaining journey = 540 ÷ 5

⇒ Required speed = 108 km/h

∴ The correct answer is 108 km/h.

Additional Information

Average Speed

The Average Speed of a journey is calculated as Total Distance ÷ Total Time. If a journey is split into two equal distances with speeds x and y, the average speed is 2xy ÷ (x + y).

Speed-Time Relation

When the distance is constant, the speed is inversely proportional to the time (S₁ ÷ S₂ = T₂ ÷ T₁). When time is constant, speed is directly proportional to distance (S₁ ÷ S₂ = D₁ ÷ D₂).

Unit Conversion

To convert speed from km/h to m/s, multiply by 5/18. To convert from m/s to km/h, multiply by 18/5.

Given :

Principal(P) = Rs.1250

Amount after two yrs.(A) = Rs.1800

Time = 2 yrs.

Formula used :

(A = P\bigg(1+\dfrac{R}{100}\bigg)^2)

Calculation :

Let the rate of interest be R % .

(1800 = 1250\bigg(1+\dfrac{R}{100}\bigg)^2) , (\dfrac{1800}{1250} = \bigg(1+\dfrac{R}{100} \bigg)^2) or (\dfrac{6}{5} = \bigg(1+\dfrac{R}{100}\bigg)) 

So, R = 20%

∴ The answer is 20 % .

Shortcut Trick ⇒ Ratio of Principle and Amount = 1250/1800 = 25/36

⇒ In 2 yrs Principle has changed from, 25x to 36x

To find Rate of change per year we've to take square root on both the sides as it has change in 2 yrs.

⇒ Principle → Amount

⇒ √{25} → √{36} 

⇒ 5 → 6

∴ % Rate of change per year = {(6 - 5)/5} × 100 = 20%

Given:

Proportional terms = 0.18 and 0.24

Concept:

If a : b :: b : c, then b = (\sqrt{ac})

Calculation:

Let x be the third proportion.

⇒ 0.18 : 0.24 :: 0.24 : x

⇒ 0.18x = 0.24 × 0.24

⇒ x = 0.0576 ÷ 0.18 = 0.32

Therefore, the third proportion of 0.18 and 0.24 is 0.32.

Alternate Method If a : b :: b : c, then b = (\sqrt{ac})

According to the question,

0.18 : 0.24 :: 0.24 : x

⇒ 0.24 = (\sqrt{0.18 × x})

⇒ (0.24)² = ((\sqrt{0.18 × x}))²

⇒ 0.0576 = 0.18 × x

⇒ x = 0.32

Shortcut Trick

Required smallest number = LCM of divisors + Remainder

LCM(15, 20, 35) = 420

Required smallest number = 420 + 8 = 428

∴ The correct answer is 428.

Alternate Method

Given:

Divisors = 15, 20, and 35

Remainder in each case = 8

Formula Used:

Smallest Number = LCM(a, b, c) + R

Calculation:

⇒ Prime factorization of 15 = 3 × 5

⇒ Prime factorization of 20 = 2² × 5

⇒ Prime factorization of 35 = 5 × 7

⇒ LCM(15, 20, 35) = 2² × 3 × 5 × 7 = 420

⇒ Smallest number = 420 + 8 = 428

∴ The correct answer is 428.

Additional Information

LCM with Different Remainders

If a number when divided by a, b, c leaves remainders p, q, r respectively and (a − p) = (b − q) = (c − r) = k, the smallest such number is LCM(a, b, c) − k.

Relation between HCF and LCM

For any two numbers, Product of numbers = HCF × LCM.

Co-prime Numbers

Two numbers are co-prime if their HCF is 1. The LCM of two co-prime numbers is their product.

Shortcut Trick

Fractional equivalent of 25% increase = +1/4

To keep the expenditure constant, the consumption must be reduced by the ratio: −1 ÷ (4 + 1) = −1/5

Percentage reduction = (1/5) × 100% = 20%

∴ The correct answer is 20%.

Alternate Method

Given:

Increase in the price of sugar = 25%

Formula Used:

Expenditure = Price × Consumption

Reduction % = [R ÷ (100 + R)] × 100% (where R is the percentage increase)

Calculations:

⇒ Let initial price = 100 units and initial consumption = 100 units.

⇒ Initial expenditure = 100 × 100 = 10000 units.

⇒ New price after 25% increase = 100 + 25 = 125 units.

⇒ Let the new consumption be C.

⇒ To keep expenditure constant: 125 × C = 10000

⇒ C = 10000 ÷ 125 = 80 units.

⇒ Decrease in consumption = 100 − 80 = 20 units.

⇒ Percentage reduction = (20 ÷ 100) × 100% = 20%.

∴ The correct answer is 20%.

Additional Information

Price and Consumption Rule

When Expenditure is constant, Price and Consumption are inversely proportional. An increase in price leads to a proportional decrease in consumption.

Percentage Increase / Decrease Concept

If value A is R% more than B, then B is less than A by exactly [R ÷ (100 + R)] × 100%.

Standard Fractional Equivalents

1/2 = 50%, 1/3 = 33.33%, 1/4 = 25%, 1/5 = 20%, 1/6 ≈ 16.66%.

Given:

Simple Interest = Rs. 3360, Rate = 6% per annum, Time = 7 years

Concept:

Simple Interest formula = PRT/100

Solution:

Principal (P) = Simple Interest × 100/(Rate × Time)

⇒ 3360 × 100/(6 × 7)

⇒ Rs. 8000

Therefore, the sum is Rs. 8000.

Shortcut Trick

Radius (r) = Total Sum ÷ (2π + 2)

⇒ r = 232 ÷ (2 × 22/7 + 2)

⇒ r = 232 ÷ (44/7 + 14/7) = 232 ÷ (58/7)

⇒ r = (232 × 7) ÷ 58 = 28 cm

∴ The correct answer is 28 cm.

Alternate Method

Given:

Sum of circumference and diameter of a circle = 232 cm.

Formula Used:

Circumference of a circle = 2πr

Diameter of a circle = 2r

Calculations:

⇒ 2πr + 2r = 232

⇒ 2r(π + 1) = 232

⇒ 2r × (22/7 + 1) = 232

⇒ 2r × (29/7) = 232

⇒ 58r / 7 = 232

⇒ r = (232 × 7) ÷ 58

⇒ r = 4 × 7

⇒ r = 28 cm

∴ The correct answer is 28 cm.

Area of a Circle

The total space occupied by the circle in a 2D plane. Formula: Area = πr²

Arc Length and Sector Area

For a central angle θ, Arc length = (θ/360) × 2πr and Area of sector = (θ/360) × πr².

Semi-Circle Properties

Perimeter of a semi-circle = πr + 2r. Area of a semi-circle = πr² ÷ 2.

Shortcut Trick

Let the third number be 100.

First number = 100 + 10 = 110

Second number = 100 + 25 = 125

Ratio = 110 : 125 = 22 : 25

∴ The correct answer is 22 : 25.

Alternate Method

Given:

First number is 10% more than the third number.

Second number is 25% more than the third number.

Calculations:

Let the third number be x.

⇒ First number = x + (10 ÷ 100) × x = 1.10x

⇒ Second number = x + (25 ÷ 100) × x = 1.25x

⇒ Required ratio = 1.10x : 1.25x

⇒ Multiplying by 100 to remove decimals = 110 : 125

⇒ Dividing both terms by 5 = 22 : 25

∴ The correct answer is 22 : 25.

Additional Information

Percentage Increase

When a value increases by x%, the new value is (100 + x)% of the original value. This allows writing final values directly without a two-step calculation.

Base Value in Percentages

It is a standard time-saving technique to assume the base value as 100 when multiple values are compared relative to a single unknown quantity.

Simplification of Ratios

A ratio a : b remains mathematically unchanged if both its antecedent (a) and consequent (b) are multiplied or divided by the same non-zero number.

Given:

Cost price = Rs.6, 450

Profit = 16%

Concept:

Selling price = (\frac{(100+profit)}{100}×Cost \space price)

Calculation:

Selling price = (\frac{(100+16)}{100}×6, 450)

⇒ (116/100) × 6450

⇒ 58 ×129

∴ The Selling price is Rs. 7482​.

Shortcut Trick

Efficiency ratio of A : B : C = (1/10) : (1/15) : (1/20)

Multiply by LCM (60) ⇒ 6 : 4 : 3

Total ratio parts = 6 + 4 + 3 = 13 units

13 units = ₹6500 ⇒ 1 unit = ₹500

B's share = 4 units = 4 × ₹500 = ₹2000

∴ The correct answer is ₹2000.

Alternate Method

Given: Time taken by A = 10 days, B = 15 days, C = 20 days. Total contract amount = ₹6500.

Formula Used: Share of wages ∝ Efficiency (when time is same for all).

Calculations:

⇒ Total Efficiency = 6 + 4 + 3 = 13

⇒ Total Wages = ₹6500

⇒ B's share = (B's Efficiency ÷ Total Efficiency) × Total Wages

⇒ B's share = (4 ÷ 13) × 6500

⇒ B's share = 4 × 500

⇒ B's share = ₹2000

∴ The correct answer is ₹2000.

Additional Information

Work and Wages Rule

Wages are distributed in the ratio of the work done by each person. If they work for the same duration, the ratio of work done is equal to the ratio of their efficiencies.

Efficiency and Time Relationship

Efficiency is inversely proportional to the time taken to complete the work. Efficiency = Total Work ÷ Time.

Pipes and Cisterns

Similar to time and work, the rate of filling/emptying is treated as efficiency, where outlet pipes have negative efficiency.

Shortcut Trick

Total weight of A, B, and C = 45 × 3 = 135 kg

Total weight of B and C = 48 × 2 = 96 kg

Weight of A = Total weight of (A + B + C) − Total weight of (B + C)

⇒ Weight of A = 135 − 96 = 39 kg

∴ The correct answer is 39 kg.

Alternate Method

Given:

Average weight of A, B and C = 45 kg

Average weight of A and B = 35 kg

Average weight of B and C = 48 kg

Formula Used:

Sum of observations = Average × Number of observations

A = ? B C

A + B + C = 135 kg

A + B = 70 kg

B + C = 96 kg

Weight of A = 135 − 96 = 39 kg

Calculations:

⇒ Sum of weights of A, B and C = 45 × 3 = 135 kg

⇒ Sum of weights of A and B = 35 × 2 = 70 kg

⇒ Sum of weights of B and C = 48 × 2 = 96 kg

⇒ We know that (A + B + C) = 135

⇒ Substituting the value of (B + C) in the above equation:

⇒ A + 96 = 135

⇒ A = 135 − 96 = 39 kg

∴ The correct answer is 39 kg.

Additional Information

Average Formula

The average of a set of numbers is their sum divided by the total number of items in that set. Formula: Average = Sum of observations ÷ Number of observations.

Combined Average

If the average of a group of n₁ observations is a₁ and that of n₂ observations is a₂, then the combined average is calculated as (n₁ × a₁ + n₂ × a₂) ÷ (n₁ + n₂).

Weighted Average

When values carry different levels of importance, the weighted average is calculated by multiplying each value by its weight, summing these products, and dividing by the overall sum of the weights.

Given:

Trade discount on marked price = 12%

Cash discount = 10%

Selling price = Rs. 9108

Formula used:

Selling price = marked price - discount% on marked price

Calculations:

Let the marked price be 100x

Selling price = 100x - 12% on 100x

Selling price = 100x - (\dfrac{12}{100}) × 100x

Selling price = 100x - 12x = 88x

Now, after applying 10% cash discount, the selling price becomes = 88x × 10% = 88x × (\dfrac{10}{100})

The machine was sold at Rs. 9108

So, 79.2x denotes Rs. 9108

Similarly, 100x will denote Rs. (\dfrac{9108 × 100}{79.2}) = Rs. 11500.

∴ The answer is Rs. 11500.

Given:

The lateral surface area of a cube is 784 cm².

Formula used:

The lateral surface area of a cube =  4a²

The volume of a cube = a³

Where, a = side

Calculation:

The lateral surface area of a cube is 784 cm2

⇒ 4a² = 784

⇒ a² = (\dfrac{784}{4}) = 196

⇒ a = (\sqrt{196}) = 14 cm

The volume of a cube = a3

⇒ 14 × 14 × 14 = 2744 cm³.

∴ The volume is 2744 cm3.

Given:

Eligible voters = 70000, cast their votes = 42000

Formula used:

% of voters = (\dfrac{number \ of \ votes \ casted}{eligible \ votes}) × 100

Calculations:

% of voters = (\dfrac{42000}{70000}) × 100

= (\dfrac{42}{70}) × 100

= 6 × 10

= 60%

∴ The answer is 60%.

Shortcut Trick

Effective Simple Interest rate for 2 years = R₁ + R₂ = 4% + 5% = 9%.

Total Simple Interest = 9% of ₹24,000 = 0.09 × 24,000 = ₹2,160.

Total Amount Due = Principal + Interest = ₹24,000 + ₹2,160 = ₹26,160.

∴ The correct answer is ₹26,160.

Alternate Method

Given: Principal (P) = ₹24,000, Rate for 1st year (R₁) = 4%, Rate for 2nd year (R₂) = 5%, Time (T) = 2 years.

Formula Used: Simple Interest (SI) = (P × R × T) / 100 and Amount (A) = P + SI.

⇒ Interest for Year 1 = (24,000 × 4 × 1) ÷ 100 = ₹960

⇒ Interest for Year 2 = (24,000 × 5 × 1) ÷ 100 = ₹1,200

⇒ Total Simple Interest = 960 + 1,200 = ₹2,160

⇒ Total Amount = 24,000 + 2,160 = ₹26,160

∴ The correct answer is ₹26,160.

Additional Information

Simple Interest on Successive Rates

In Simple Interest, different rates for different years are simply added to find the net effective rate: R_eff = R₁ + R₂ + R₃...

Amount Formula

The total Amount can also be calculated directly using the formula: A = P × (1 + (R₁ + R₂ + ... + R_n)/100).

SI vs Compound Interest

Unlike Compound Interest, the interest in Simple Interest is always calculated on the original Principal, making it easier to sum up annual interest amounts.

Shortcut Trick

Successive ratio method: 20% loss = 1/5 (Ratio 5 → 4) and 25% spent = 1/4 (Ratio 4 → 3).

Combined Ratio = (5 × 4) : (4 × 3) = 20 : 12 = 5 : 3.

Final 3 units = ₹480 ⇒ 1 unit = 480 ÷ 3 = 160.

Original amount = 5 units = 5 × 160 = ₹800.

∴ The correct answer is ₹800.

Alternate Method

Given: First loss = 20%, Second expenditure = 25% of the remaining amount, Final balance = ₹480.

Formula Used: Final Value = Initial Value × (1 − r₁/100) × (1 − r₂/100)

Calculations:

⇒ Let the original money be x.

⇒ After losing 20%, remaining money = x × (80/100) = 0.8x.

⇒ Spending 25% of remainder = 0.8x × (25/100) = 0.2x.

⇒ Final balance = 0.8x − 0.2x = 0.6x.

⇒ 0.6x = 480

⇒ x = 480 ÷ 0.6 = 800.

∴ The correct answer is ₹800.

Additional Information

Successive Percentage Change

When a value changes by a% and then b%, the net effective change is given by the formula (a + b + ab/100)%. For decreases, use negative values.

Fractional Equivalents

Simplifying percentages to fractions (e.g., 20% = 1/5, 25% = 1/4) allows for quicker ratio-based calculations in multi-step word problems.

Base Value Concept

Always distinguish whether a percentage applies to the original base or the remaining balance, as this significantly changes the final result.

Formula Used:

Profit percentage = (Profit/Cost price) x 100

Calculation:

Let's assume the marked price of each pencil is Rs. 1. So, the retailer buys 75 pencils for Rs. 60.

Now, if the marked price of each pen is Rs. 1, then

Selling price = 1 - 6/100 = 0.94

The selling price of 75 pencils = 75 x 0.94 = Rs. 70.5

The cost price of 75 pencils is Rs. 60. So, the profit made by the retailer is:

Profit = Selling price - Cost price

Profit = 70.5 - 60 = Rs. 10.5

Profit percentage = (10.5/60) x 100

Profit percentage = 17.5%

Therefore, the profit percentage for the retailer is 17.5%.

Shortcut Trick

For any cuboid, the sum of its dimensions can be found directly using the formula: Sum = √(Diagonal² + Surface Area)

⇒ Sum = √(11² + 240)

⇒ Sum = √(121 + 240)

⇒ Sum = √361 = 19 cm

∴ The correct answer is 19 cm.

Alternate Method

Given:

Length of diagonal (d) = 11 cm

Total Surface Area (S) = 240 cm²

Let the length, breadth, and height of the cuboid be l, b, and h respectively.

        l h b d = 11 cm Area = 240 cm²

Formula Used:

Diagonal of a cuboid = √(l² + b² + h²)

Total Surface Area = 2(lb + bh + hl)

Algebraic Identity: (l + b + h)² = l² + b² + h² + 2(lb + bh + hl)

Calculations:

⇒ √(l² + b² + h²) = 11

Squaring both sides:

⇒ l² + b² + h² = 121

We are given the Surface Area:

⇒ 2(lb + bh + hl) = 240

Substituting these values into the standard algebraic identity:

⇒ (l + b + h)² = 121 + 240

⇒ (l + b + h)² = 361

⇒ l + b + h = √361 = 19

∴ The correct answer is 19 cm.

Additional Information

Volume of a Cuboid

The volume of a cuboid is the product of its length, breadth, and height: V = l × b × h.

Sum of Length of All Edges

Since a cuboid has exactly 12 edges (4 each of length, breadth, and height), the sum of their lengths is calculated as 4(l + b + h).

Cube Properties

For a cube with an edge side equal to 'a', the body diagonal is given by a√3, and the total surface area is 6a².

Given:

A alone can do a work = 6 days

B alone can do a work = 8 days

Formula used:

Total work = efficiency × total time taken

Calculation:

Now,

Time taken to complete the work (A + B) = 24/7

∴ The correct answer is 24/7.

Shortcut Trick

The extra time taken to cross the platform instead of the pole is directly due to the length of the platform.

Extra time = 51 sec − 27 sec = 24 sec.

Speed in m/s = 42 × (5/18) = 35/3 m/s.

Length of platform = Speed × Extra time = (35/3) × 24 = 35 × 8 = 280 m.

∴ The correct answer is 280 m.

Alternate Method

Given:

Speed of the train = 42 km/h

Time to cross electric pole (T₁) = 27 sec

Time to cross platform (T₂) = 51 sec

Formula Used:

Distance = Speed × Time

Speed (m/s) = Speed (km/h) × (5/18)

⇒ Speed in m/s = 42 × (5/18) = 35/3 m/s

⇒ Length of train (L) = Speed × Time to cross pole

⇒ L = (35/3) × 27 = 35 × 9 = 315 m

⇒ Total distance to cross platform = Length of train + Length of platform (P)

⇒ L + P = Speed × Time to cross platform

⇒ 315 + P = (35/3) × 51

⇒ 315 + P = 35 × 17

⇒ 315 + P = 595

⇒ P = 595 − 315 = 280 m

∴ The correct answer is 280 m.

Additional Information

Unit Conversion

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

Train Crossing a Point Object
