Question 3

Two pipes can fill a cistern, individually, in 98 min and 28 min, respectively. There is a pipe located at the bottom of the cistern to empty it. If all the three pipes are opened simultaneously, then the empty cistern gets filled in 42 min. How long will the pipe at the bottom of the cistern take to empty the completely filled cistern if no other pipe is then open?

  1. AOption (a)

    606/13 min

  2. BOption (b)

    588/13 min

  3. COption (c)

    577/13 min

  4. DOption (d)

     583/13 min

View answer & explanation

Correct answer

Answer: (b)B.

588/13 min

Why this answer is correct

Shortcut Trick

Total Capacity (LCM of 98, 28, 42) = 588 units.

Efficiency of Pipe 1 = 588 ÷ 98 = 6 units/min.

Efficiency of Pipe 2 = 588 ÷ 28 = 21 units/min.

Combined Efficiency (All 3 pipes) = 588 ÷ 42 = 14 units/min.

Efficiency of Emptying Pipe = (6 + 21) − 14 = 13 units/min.

Time to empty = 588 ÷ 13 min.

∴ The correct answer is 588/13 min.

Alternate Method

Given: Time taken by Inlet A = 98 min, Inlet B = 28 min, Combined (A+B−C) = 42 min.

PipeTime (min)Total CapacityEfficiency
Pipe A (+)985886
Pipe B (+)2821
A + B − C4214

⇒ Total positive efficiency (A + B) = 6 + 21 = 27 units/min

⇒ Net efficiency with outlet pipe = 14 units/min

⇒ Efficiency of Outlet Pipe C = (A + B) − Net efficiency

⇒ Efficiency of Pipe C = 27 − 14 = 13 units/min

⇒ Time taken by Outlet Pipe C alone = Total Capacity ÷ Efficiency

⇒ Time = 588 ÷ 13 min

∴ The correct answer is 588/13 min.

Additional Information

Pipes and Cisterns Convention

Inlet pipes are treated as positive work (+) and outlet/leakage pipes are treated as negative work (−).

Total Work Formula

Total Work (Capacity) = Time taken × Efficiency. For multiple pipes, Net Efficiency = ∑(Individual Efficiencies).

Unitary Method for Time

If a pipe fills in 'x' hours and another empties in 'y' hours, net work in 1 hour = (1/x − 1/y).

View answer & explanation

Correct answer

Answer: (d)D.

5

Why this answer is correct

Given Numbers: 611, 733, 279, 265, 370

Let's identify the highest and lowest numbers from the given set:

  • Highest number: Among 611, 733, 279, 265, 370, the highest number is 733.
  • Lowest number: Among 611, 733, 279, 265, 370, the lowest number is 265.

Now, let's extract the required digits:

  • The second digit of the highest number (733) is 3.
  • The first digit of the lowest number (265) is 2.

Finally, we need to find the resultant if the second digit of the highest number is added to the first digit of the lowest number:

→ 3 + 2 = 5.

The resultant is 5.

Hence, the correct answer is "Option 4".

Question 5

Gopal gets a 2% increase in his sale amount in the first year and a 20% increase in the second year, and with that his present sale is ₹1,83,600. What was his sale (in ₹) two years ago?

  1. AOption (a)

    1,30,000

  2. BOption (b)

    1,50,000

  3. COption (c)

    1,53,000

  4. DOption (d)

    1,80,000

View answer & explanation

Correct answer

Answer: (b)B.

1,50,000

Why this answer is correct

Shortcut Trick

Let the initial sale be 100%.

Effective Multiplier = 1.02 × 1.20 = 1.224

Initial Sale = Present Sale ÷ 1.224

Initial Sale = 1,83,600 ÷ 1.224 = 1,50,000

∴ The correct answer is ₹1,50,000.

Alternate Method

Given:

Increase in 1st year = 2%

Increase in 2nd year = 20%

Present Sale = ₹1,83,600

Formula Used:

Final Value = Initial Value × (1 + R1/100) × (1 + R2/100)

Calculations:

Let the sale 2 years ago be X.

⇒ X × (1 + 2/100) × (1 + 20/100) = 1,83,600

⇒ X × (102/100) × (120/100) = 1,83,600

⇒ X × (51/50) × (6/5) = 1,83,600

⇒ X × 306 / 250 = 1,83,600

⇒ X = (1,83,600 × 250) / 306

⇒ X = 600 × 250

⇒ X = 1,50,000

∴ The correct answer is ₹1,50,000.

Additional Information

Successive Percentage Change

When a value changes by a% and then by b%, the net change is given by (a + b + ab/100)%.

Base Change Rule

To find the initial value from the final value after an increase of r%, use Initial = Final ÷ (1 + r/100).

Multiplication Factor

An increase of x% corresponds to a multiplying factor of (1 + x/100). For 20%, the factor is 1.2.

Question 6

The equivalent fraction of 2.777... is:

  1. AOption (a)

    2811\frac{28}{11}

  2. BOption (b)

    259\frac{25}{9}

  3. COption (c)

    212\frac{21}{2}

  4. DOption (d)

    293\frac{29}{3}

View answer & explanation

Correct answer

Answer: (b)B.

259\frac{25}{9}

Why this answer is correct

Given:

The repeating decimal is: 2.777...

Formula used:

Let x = 2.777... (a repeating decimal)

Multiply both sides by 10n (where n is the number of repeating digits) to eliminate the repeating part.

Then solve for x.

Calculations:

Let x = 2.777...

Multiply by 10 (since 1 digit is repeating):

⇒ 10x = 27.777...

Now subtract the original equation (x = 2.777...) from this:

⇒ 10x - x = 27.777... - 2.777...

⇒ 9x = 25

⇒ x = 25/9

∴ The equivalent fraction of 2.777... is (25/9), and the correct answer is option (2).

Question 11

Standard base pairing in DNA occurs due to which type of bonding?

  1. AOption (a)

     Ionic bonding

  2. BOption (b)

    Van Der Waals interactions

  3. COption (c)

    Covalent bonding

  4. DOption (d)

    Hydrogen bonding

View answer & explanation

Correct answer

Answer: (d)D.

Hydrogen bonding

Why this answer is correct

The Correct answer is Hydrogen bonding.

Key Points

  • In DNA, the two complementary strands are held together by hydrogen bonds between the nitrogenous bases.
  • Adenine (A) always pairs with Thymine (T) through two hydrogen bonds, while Guanine (G) pairs with Cytosine (C) using three hydrogen bonds.
  • This specific pairing is known as complementary base pairing, which is essential for the accurate replication of genetic material.
  • Hydrogen bonds are weak, non-covalent interactions that allow the double helix structure of DNA to unzip during replication and transcription.
  • Although individually weak, the cumulative effect of a large number of hydrogen bonds provides structural stability to the DNA double helix.
  • The double helix model of DNA was first proposed by James Watson and Francis Crick, and their discovery highlighted the role of hydrogen bonding in maintaining DNA’s structural integrity.
  • These bonds ensure that mutations are minimized by enabling specificity in base pairing during DNA replication.
  • Hydrogen bonding occurs due to the difference in electronegativity between the hydrogen atom and the electronegative atoms (e.g., oxygen or nitrogen) involved in the base pairs.

 Additional Information

  • Ionic bonding
  • Ionic bonds occur due to the electrostatic attraction between oppositely charged ions, which is not relevant in the context of DNA base pairing.
  • Examples of ionic bonding are typically found in compounds like sodium chloride (NaCl).
  • In DNA, ionic interactions are involved in the stabilization of the double helix through interactions between the negatively charged phosphate backbone and positively charged ions, but they are not responsible for base pairing.
  • Van Der Waals interactions
  • Van Der Waals forces are weak, short-range forces that arise from fluctuating dipoles, contributing to DNA’s overall structural stability.
  • These interactions are present between stacked bases in the DNA double helix, known as base stacking interactions, but they do not play a direct role in base pairing.
  • Covalent bonding
  • Covalent bonds involve the sharing of electron pairs between atoms, and they are responsible for the formation of the sugar-phosphate backbone in DNA.
  • These bonds are much stronger than hydrogen bonds and provide the primary structure of DNA, but they do not mediate base pairing.

529

Why this answer is correct

![Solved] Solve 10 + 21 ÷ (9 – 2).](https://storage.googleapis.com/yourmocktest-papers/papers/media/ext/05033828bccdc58309b2410d.png)

Given interchange rules:

  • ‘+’ and ‘−’ are interchanged.
  • ‘×’ and ‘÷’ are interchanged.

The given equation is:

173 ÷ 3 − 135 × 5 + 17 = ?

Replace the operators with their corresponding new meanings:

173 × 3 + 135 ÷ 5 − 17 = ?

Now, we solve the equation following the BODMAS/PEMDAS rule (Brackets, Orders, Division/Multiplication from left to right, Addition/Subtraction from left to right):

= 173 × 3 + 135 ÷ 5 − 17

= 519 + 27 − 17

  3. COption (c)

    70

  4. DOption (d)

    78

View answer & explanation

Correct answer

Answer: (a)A.

74

Why this answer is correct

Shortcut Trick

According to the British Flag Theorem, for any point P inside a rectangle ABCD:

PA2 + PC2 = PB2 + PD2

692 + 382 = 272 + PD2

4761 + 1444 = 729 + PD2

6205 − 729 = PD2 ⇒ PD2 = 5476

PD = √5476 = 74 cm

∴ The correct answer is 74 cm.

Alternate Method

Given: PA = 69 cm, PB = 27 cm, PC = 38 cm.

Formula Used: PA2 + PC2 = PB2 + PD2 (British Flag Theorem).

Question 20

A compound has an empirical formula CH₂ and a molar mass of 56 g/mol. Its molecular formula is:

  1. AOption (a)

    CH₂

  2. BOption (b)

    C₃H₆

  3. COption (c)

    C₂H₄

  4. DOption (d)

    C₄H₈

View answer & explanation

Correct answer

Answer: (d)D.

C₄H₈

Why this answer is correct

The Correct answer is C₄H₈.

Key Points

  • The question asks us to determine the molecular formula of a compound with an empirical formula CH₂ and a molar mass of 56 g/mol.
  • The empirical formula represents the simplest ratio of atoms in a compound. In this case, CH₂ indicates there is 1 carbon atom for every 2 hydrogen atoms.
  • The molar mass of CH₂ is calculated as follows:
  • Carbon (C): Atomic mass = 12 g/mol.
  • Hydrogen (H): Atomic mass = 1 g/mol (for 2 hydrogen atoms, total = 2 g/mol).
  • Total molar mass of CH₂ = 12 + 2 = 14 g/mol.
  • To find the molecular formula, divide the molar mass of the compound (56 g/mol) by the molar mass of the empirical formula (14 g/mol):
  • 56 ÷ 14 = 4.
  • This means the molecular formula is 4 times the empirical formula.
  • Multiply CH₂ by 4 to get the molecular formula:
  • Carbon atoms: 1 × 4 = 4.
  • Hydrogen atoms: 2 × 4 = 8.
  • Molecular formula = C₄H₈.
  • Thus, the correct molecular formula of the compound is C₄H₈.

 Additional Information

  • Empirical Formula
  • The empirical formula represents the simplest whole-number ratio of atoms in a compound.
  • For example, CH₂ means that for every 1 carbon atom, there are 2 hydrogen atoms.
  • It does not provide the exact number of atoms in the molecule, which is determined by the molecular formula.
  • Molecular Formula
  • The molecular formula gives the actual number of atoms of each element in a molecule.
  • It is a multiple of the empirical formula, determined by dividing the compound’s molar mass by the empirical formula mass.
  • For example, if the empirical formula is CH₂ and the molar mass is 56 g/mol, the molecular formula is C₄H₈.
  • Incorrect Options
  • CH₂: This is the empirical formula, not the molecular formula.
  • C₃H₆: While this follows a similar ratio (1:2), its molar mass is 42 g/mol, which does not match the given molar mass of 56 g/mol.
  • C₂H₄: This also follows the 1:2 ratio, but its molar mass is only 28 g/mol, which is incorrect.

View answer & explanation

Correct answer

Answer: (c)C.

12\frac{1}{2}

Why this answer is correct

Shortcut Trick

Given sin A = 3/4 (Perpendicular/Hypotenuse).

Using Pythagorean triplet logic: Base = √(42 − 32) = √(16 − 9) = √7.

Then cos A = Base/Hypotenuse = √7/4.

Value required = (2 × √7/4) ÷ √7 = 2/4 = 1/2.

∴ The correct answer is 1/2.

Alternate Method

Given: sin A = 3/4

Formula Used: cos2A = 1 − sin2A

⇒ cos2A = 1 − (3/4)2

⇒ cos2A = 1 − 9/16 = 7/16

⇒ cos A = √7/4

⇒ Target Expression = (2 × cos A) / √7

⇒ Target Expression = (2 × (√7 / 4)) / √7

⇒ Target Expression = (2√7) / (4√7)

⇒ Target Expression = 2/4 = 1/2

∴ The correct answer is 1/2.

Additional Information

Trigonometric Ratios

For any angle A, sin A = Perpendicular/Hypotenuse, cos A = Base/Hypotenuse, and tan A = Perpendicular/Base.

Pythagorean Identity

The fundamental identity is sin2A + cos2A = 1. This allows finding one ratio if the other is known.

Pythagoras Theorem

In a right-angled triangle, Hypotenuse2 = Base2 + Perpendicular2.

Given Conditions:

  1. If the 1st letter is a vowel and the last letter is a consonant, their codes are to be interchanged.
  2. If the 2nd letter is a vowel and the last letter is a consonant, both are to be coded as ‘W’.
  3. If the 3rd and 4th letters are consonants, both are to be coded as the code for the 3rd letter.
  4. If the 1st and 2nd letters are vowels, then both are to be coded as ‘Q’.

Group to be coded: APUXR

Analysis of the group APUXR:

  • 1st letter: A (Vowel)
  • 2nd letter: P (Consonant)
  • 3rd letter: U (Vowel)
  • 4th letter: X (Consonant)
  • 5th letter (last): R (Consonant)

Checking the conditions:

  • Condition 1: "If the 1st letter is a vowel and the last letter is a consonant, their codes are to be interchanged."

Here, 1st letter 'A' is a vowel and the last letter 'R' is a consonant. This condition applies.

  • Condition 2: "If the 2nd letter is a vowel and the last letter is a consonant, both are to be coded as ‘W’."

Here, the 2nd letter 'P' is a consonant, not a vowel. This condition does not apply.

  • Condition 3: "If the 3rd and 4th letters are consonants, both are to be coded as the code for the 3rd letter."

Here, the 3rd letter 'U' is a vowel, not a consonant. This condition does not apply.

  • Condition 4: "If the 1st and 2nd letters are vowels, then both are to be coded as ‘Q’."

Here, the 2nd letter 'P' is a consonant, not a vowel. This condition does not apply.

Applying Condition 1:

The codes for the 1st letter (A) and the last letter (R) are to be interchanged.

Original codes:

  • A = 2
  • P = 9
  • U = %
  • X = 6
  • R = 4

After interchanging the codes for A and R:

  • A's new code will be R's original code, which is 4.
  • R's new code will be A's original code, which is 2.

Final Code for APUXR:

  • A becomes 4
  • P remains 9
  • U remains %
  • X remains 6
  • R becomes 2

Therefore, the code for APUXR is 4 9 % 6 2.

Hence, the correct answer is "Option 2"$.

View answer & explanation

Correct answer

Answer: (c)C.

 Only 2

Why this answer is correct

The Correct answer is Only 2.

Key Points

  • The National Mission on Natural Farming (NMNF) was launched to promote sustainable and eco-friendly farming practices in India.
  • The mission emphasizes the adoption of Natural Farming methods, which involve the use of bio-based inputs instead of synthetic chemicals.
  • One of the key components of the NMNF is the establishment of Bio-input Resource Centres to provide farmers with inputs for Natural Farming. These inputs include bio-fertilisers, bio-pesticides, and other organic resources.
  • These Bio-input Resource Centres will help reduce dependency on chemical fertilizers and promote the use of naturally available materials, thus ensuring soil health, environmental sustainability, and cost-effective farming practices.
  • While the mission supports these initiatives, the total approved outlay for the NMNF is not ₹1,000 crore as mentioned in the first statement, making the first statement incorrect.
  • The NMNF also aims to improve the livelihoods of farmers by reducing the cost of cultivation and increasing productivity through natural methods.

 Additional Information

  • Incorrect Statement 1:
  • The first statement mentioned that the total approved outlay of NMNF till 2025-26 is ₹1,000 crore. This is factually incorrect as the actual approved outlay is different and not ₹1,000 crore.
  • It is important to note that the financial allocation for NMNF is determined based on the requirements of the implementation plan, and the exact figures may vary based on the government’s budgetary approvals.
  • Natural Farming Practices:
  • Natural Farming is a chemical-free and climate-resilient method of farming.
  • It uses cow dung, cow urine, and other natural substances to prepare Jeevamrit (liquid bio-fertiliser) and other bio-inputs.
  • It avoids the use of synthetic fertilizers and pesticides, focusing instead on soil health improvement and the use of locally available resources.
  • This approach is aligned with the principles of sustainability and aims to reduce input costs for farmers.
  • Relevance of Bio-input Resource Centres:
  • These centres act as hubs for preparing and distributing bio-inputs to farmers.
  • They play a critical role in ensuring the availability of natural farming inputs in remote areas where farmers may lack access to such resources.
  • By promoting the use of bio-inputs, these centres contribute to organic certification and market linkages, ensuring better incomes for farmers adopting natural farming methods.

    ₹2,904

View answer & explanation

Correct answer

Answer: (d)D.

₹2,904

Why this answer is correct

Shortcut Trick

For half-yearly compounding, the rate becomes half (20% ÷ 2 = 10%) and time becomes double (1 year × 2 = 2 periods).

Effective Rate for 2 periods at 10% = 10 + 10 + (10 × 10)/100 = 21%.

Amount = Principal × (100 + Effective Rate)% = 2400 × 121%

Amount = 24 × 121 = 2904

∴ The correct answer is ₹2,904.

Alternate Method

Given:

Principal (P) = ₹2,400

Annual Rate (R) = 20%

Time (T) = 1 year

Compounding: Half-yearly

Formula Used:

Amount (A) = P(1 + r/100)n

Where r = Half-yearly rate and n = Number of half-years.

Calculations:

⇒ r = R ÷ 2 = 20% ÷ 2 = 10%

⇒ n = T × 2 = 1 × 2 = 2 half-years

⇒ A = 2400(1 + 10/100)2

⇒ A = 2400(11/10)2

⇒ A = 2400 × (121/100)

⇒ A = 24 × 121

⇒ A = 2904

∴ The correct answer is ₹2,904.

Additional Information

Compounding Half-Yearly

When interest is compounded semi-annually, the nominal annual rate is divided by 2, and the number of years is multiplied by 2.

Effective Annual Rate (EAR)

The actual interest earned in a year. Formula: EAR = (1 + r/n)n − 1, where n is the number of compounding periods per year.

View answer & explanation

Correct answer

Answer: (c)C.

4,968

Why this answer is correct

Shortcut Trick

Ratio of Profit is based on Investment × Time.

Ratio of Investment X : Y : Z = 13 : 20 : 15.

X's share = 13 × 12 = 156.

Y's share = (20 × 7) + (20 × 0.67 × 5) = 140 + 67 = 207.

Z's share = (15 × 7) + (15 × 0.76 × 5) = 105 + 57 = 162.

Ratio X : Y : Z = 156 : 207 : 162 = 52 : 69 : 54.

Total units = 52 + 69 + 54 = 175. Share of Z = (54 ÷ 175) × 16100 = 54 × 92 = 4968.

∴ The correct answer is ₹4,968.

Alternate Method

Given → Initial investment ratio 13 : 20 : 15. Time period = 12 months. Formulas: Profit Share = Investment × Time | Total Profit = Sum of individual shares.

⇒ X's Profit units = 13 × 12 = 156 units. ⇒ Y's Profit units: Y withdrew 33% of 20 = 6.6. Remaining = 20 − 6.6 = 13.4. ⇒ Y = (20 × 7) + (13.4 × 5) = 140 + 67 = 207 units. ⇒ Z's Profit units: Z withdrew 24% of 15 = 3.6. Remaining = 15 − 3.6 = 11.4. ⇒ Z = (15 × 7) + (11.4 × 5) = 105 + 57 = 162 units. ⇒ Ratio of Profit = 156 : 207 : 162 = 52 : 69 : 54. ⇒ Total Profit units = 52 + 69 + 54 = 175. ⇒ 175 units = ₹16,100 ⇒ 1 unit = 16100 ÷ 175 = 92. ⇒ Z's share = 54 × 92 = ₹4,968.

∴ The correct answer is ₹4,968.

Why this answer is correct

Given Statements:

  1. All cars are old.
  2. Some old are new.
  3. Some new are red.

The least possible Venn diagram for the given statements is shown below.

Conclusions:

I. All old are cars. → False (The statement "All cars are old" means that cars are a subset of old things. It does not mean that all old things are necessarily cars. There can be other old things that are not cars.)

II. Some new are old. → True (The statement "Some old are new" directly implies that there is an overlap between the category 'old' and 'new'. If some members of 'old' are also 'new', then it logically follows that those same members of 'new' are also 'old'.)

Therefore, only conclusion II follows.

Hence, the correct answer is "Option 2".

  4. DOption (d)

     3,195

View answer & explanation

Correct answer

Answer: (a)A.

 3,102

Why this answer is correct

Shortcut Trick

Saving % = 100% − 33% = 67%

Given, 67% = ₹6,298

Expenses (33%) = (6,298 ÷ 67) × 33

Expenses = 94 × 33 = ₹3,102

∴ The correct answer is ₹3,102.

Alternate Method

Given:

Monthly Expenses percentage = 33%

Monthly Savings = ₹6,298

Formula Used:

Income = Expenses + Savings

Calculations:

⇒ Savings % = 100% − 33% = 67%

⇒ 67% of Income = ₹6,298

⇒ 1% of Income = 6,298 ÷ 67

⇒ 1% of Income = 94

⇒ Monthly Expenses (33%) = 33 × 94

⇒ Monthly Expenses = ₹3,102

∴ The correct answer is ₹3,102.

Additional Information

Percentage Change

Percentage change is calculated as (Change ÷ Original Value) × 100.

Income-Expenditure Relation

View answer & explanation

Correct answer

Answer: (a)A.

 The Harvard architecture allows simultaneous fetching of instructions and data, potentially improving performance, while the von Neumann architecture typically fetches them sequentially from the same memory space.

Why this answer is correct

The Correct answer is Option 1.

Key Points

  • The von Neumann architecture uses a single memory space for both instructions and data, meaning the CPU fetches them sequentially. This can lead to a bottleneck known as the von Neumann bottleneck, where the CPU waits for instructions or data due to limited bandwidth.
  • In contrast, the Harvard architecture separates memory for instructions and data, allowing them to be accessed simultaneously. This separation can significantly improve performance, especially in systems requiring high-speed processing.
  • The Harvard architecture is particularly useful in embedded systems and real-time applications, where deterministic performance is critical.
  • The von Neumann architecture is widely used in general-purpose computers, as it simplifies the design and programming model by using a single memory space.
  • The separation of memory in the Harvard architecture often requires more complex hardware, but it provides better throughput for specific tasks.
  • Both architectures are foundational to modern computing, with hybrid systems often combining features of both to balance simplicity and performance.

 Additional Information

  • The von Neumann Architecture
  • Proposed by John von Neumann in the 1940s, this architecture forms the basis of most modern computers.
  • It uses a single memory space where both program instructions and data are stored.
  • The single memory architecture leads to what is called the von Neumann bottleneck, where the CPU waits for data or instructions due to limited memory bandwidth.
  • Examples of devices using von Neumann architecture include desktop computers, laptops, and other general-purpose systems.
  • The Harvard Architecture
  • This architecture was first used in the Harvard Mark I computer.
  • It has separate memory spaces for instructions and data, allowing parallel access and higher performance.
  • Commonly found in microcontrollers and digital signal processors (DSPs).
  • Examples of devices using Harvard architecture include embedded systems, such as those in automotive applications or industrial control systems.
  • Hybrid Architectures
  • Many modern processors combine features of both architectures to leverage the benefits of each.
  • For instance, they may use a Harvard-like architecture internally for instruction and data caches while maintaining a von Neumann-like unified main memory.
  • This hybrid approach is common in modern CPUs and GPUs.

Answer: (a)A.

11

Why this answer is correct

Shortcut Trick

Let the son's age 3 years ago be x.

Father's age 3 years ago = 2x + 14.

Difference between their ages = (2x + 14) − x = x + 14.

The age difference remains constant; when the father is twice the son's age, the son's age must equal the difference (x + 14).

Future age of son = x + 14. Present age of son = x + 3.

Years from now = (x + 14) − (x + 3) = 11 years.

∴ The correct answer is 11 years.

⇒ 3 years ago: (F − 3) = 2(S − 3) + 14

⇒ F − 3 = 2S − 6 + 14

⇒ F − 2S = 11 ...........(i)

Let the father be twice his son's age after n years from now.

⇒ (F + n) = 2(S + n)

⇒ F + n = 2S + 2n

⇒ F − 2S = n ...........(ii)

Equating (i) and (ii):

⇒ n = 11

∴ The correct answer is 11 years.

Additional Information

Constant Age Difference

The difference between the ages of two people remains constant regardless of the number of years that pass.

Ratio of Ages

If the ratio of ages is given for two different time periods, use the cross-multiplication method or equate the difference in ratio units.

Twice Age Rule

When person A is twice the age of person B, the age of person B at that moment is exactly equal to the difference in their ages.

Question 48

A man covers distances of 100 km, 408 km, and 1460 km at the speeds of 20 km/hr, x km/hr, and 20 km/hr, respectively. If his average speed for the whole journey is 20 km/hr, then what is the value of x?

  1. AOption (a)

    22

  2. BOption (b)

    20

  3. COption (c)

    15

  4. DOption (d)

    25

View answer & explanation

Correct answer

Answer: (b)B.

20

Why this answer is correct

Shortcut Trick Since overall Average Speed = Total Distance ÷ Total Time: ⇒ (D1 + D2 + D3) ÷ 20 = (D1 ÷ 20) + (D2 ÷ x) + (D3 ÷ 20) ⇒ (D1 ÷ 20) + (D2 ÷ 20) + (D3 ÷ 20) = (D1 ÷ 20) + (D2 ÷ x) + (D3 ÷ 20) ⇒ D2 ÷ 20 = D2 ÷ x ⇒ x = 20 ∴ The correct answer is 20 km/hr. Alternate Method

100 km 408 km 1460 km

20 km/hr x km/hr 20 km/hr

Overall Average Speed = 20 km/hr

Given: Distances: D1 = 100 km, D2 = 408 km, D3 = 1460 km Speeds: S1 = 20 km/hr, S2 = x km/hr, S3 = 20 km/hr Average speed = 20 km/hr Formula Used: Average Speed = Total Distance ÷ Total Time Time = Distance ÷ Speed Calculations: ⇒ Total Distance = 100 + 408 + 1460 = 1968 km ⇒ Total Time = (100 ÷ 20) + (408 ÷ x) + (1460 ÷ 20) ⇒ Total Time = 5 + (408 ÷ x) + 73 = 78 + (408 ÷ x) hours ⇒ Average Speed = 1968 ÷ [78 + (408 ÷ x)] ⇒ 20 = 1968 ÷ [78 + (408 ÷ x)] ⇒ 78 + (408 ÷ x) = 1968 ÷ 20 ⇒ 78 + (408 ÷ x) = 98.4 ⇒ 408 ÷ x = 98.4 − 78 = 20.4 ⇒ x = 408 ÷ 20.4 = 4080 ÷ 204 = 20 ∴ The correct answer is 20 km/hr. Additional Information Average Speed Concept Average speed is the measure of the total distance traveled completely over the total time elapsed. It accounts for speed variations across the trip. Formula: Average Speed = Total Distance ÷ Total Time. Equal Distances Average Speed When a person travels two equal parts of a journey at speeds x and y, the average speed for the whole journey reduces to exactly 2xy ÷ (x + y). Relative Speed For two objects moving in the same direction at speeds a and b (where a > b), their relative speed is (a − b). If they move in opposite directions, it is (a + b).

View answer & explanation

Correct answer

Answer: (d)D.

To protect the supremacy of the Constitution and fundamental rights

Why this answer is correct

The Correct answer is To protect the supremacy of the Constitution and fundamental rights.

Key Points

  • Judicial review in India ensures the protection of the supremacy of the Constitution, which is the highest law of the land.
  • It is a mechanism for safeguarding fundamental rights, as guaranteed under Part III of the Indian Constitution, against legislative and executive actions.
  • The judiciary has the authority to review the actions and decisions of the legislature and executive to ensure they do not violate the Constitutional provisions.
  • Judicial review enables the courts to declare laws or actions null and void if they are inconsistent with the Constitution.
  • It upholds the principle of constitutional morality, ensuring that all laws and policies align with the values and principles enshrined in the Constitution.
  • This process helps maintain the balance between the various organs of the government, preventing any one organ from exceeding its powers.
  • Judicial review is crucial in a democracy like India, where the judiciary acts as the guardian of the Constitution and the rights of citizens.
  • The concept finds its roots in Articles 13, 32, and 226 of the Indian Constitution, which empower the judiciary to review laws and protect fundamental rights.
  • It is especially significant in cases involving the violation of rights such as freedom of speech, equality, and personal liberty.

 Additional Information

  • To allow the judiciary to make laws
  • The judiciary does not have the power to legislate; its role is limited to interpreting and applying the law as per the Constitution.
  • Law-making is the exclusive domain of the legislature in India, as per the separation of powers principle.
  • Judicial review does not involve creating laws but reviewing them for Constitutional validity.
  • To maintain federal balance between Centre and States
  • While judicial review does play a role in resolving disputes between the Centre and States, this is not its primary purpose.
  • Federal balance is maintained through mechanisms like the Finance Commission and specific provisions in the Constitution, such as Article 246, detailing the division of legislative powers.
  • To ensure the supremacy of the Parliament
  • In India, the Constitution, not the Parliament, is supreme, unlike in the UK where parliamentary sovereignty exists.
  • The judiciary reviews parliamentary laws to ensure they align with the Constitutional framework.
  • Judicial review acts as a check on parliamentary supremacy, ensuring that laws do not violate fundamental rights.

Question 51

A tangent is drawn from point P to a circle with centre O. The radius of the circle is 7 cm, and the distance from point P to the centre O is 25 cm. What is the length of the tangent from point P to the point of tangency?

  1. AOption (a)

    21 cm

  2. BOption (b)

    27 cm

  3. COption (c)

    31 cm

  4. DOption (d)

    24 cm

View answer & explanation

Correct answer

Answer: (d)D.

24 cm

Why this answer is correct

Shortcut Trick

The radius, tangent, and distance from the center form a right-angled triangle where the distance from the center is the hypotenuse.

Using the Pythagorean triplet (7, 24, 25):

Tangent length = √(252 − 72) = √(625 − 49) = √576 = 24 cm.

∴ The correct answer is 24 cm.

Alternate Method

Given:

Radius of the circle (OT) = 7 cm

Distance from point P to center O (OP) = 25 cm

Formula Used:

In a circle, the tangent is perpendicular to the radius at the point of tangency. Thus, ΔOTP is a right-angled triangle at T.

By Pythagoras Theorem: PT2 + OT2 = OP2

Calculations:

⇒ PT2 + 72 = 252

⇒ PT2 + 49 = 625

⇒ PT2 = 625 − 49

Why this answer is correct

The Correct answer is 45%.

Key Points

  • The Global Debt Report 2025 highlights significant concerns about the maturity of sovereign debt across various countries.
  • According to the report, approximately 45% (or 0.45) of sovereign debt from OECD (Organisation for Economic Co-operation and Development) countries is expected to mature by the year 2027.
  • The OECD is a group of developed countries that collaborate to promote economic growth and trade, and they collectively hold substantial levels of debt.
  • The maturity of such a large portion of debt creates challenges for these countries, as they will need to refinance or repay this debt within the stipulated timeline.
  • This scenario could lead to potential risks such as higher interest rates, increased debt burdens, and pressure on national budgets.
  • Global economic uncertainties, such as inflation and geopolitical tensions, further compound these debt-related challenges for the OECD nations.
  • The report serves as a warning for countries to adopt prudent fiscal policies and prepare strategies to manage this maturing debt effectively.

 Additional Information

  • OECD and Sovereign Debt
  • The OECD consists of 38 member countries, including nations like the United States, Germany, France, Japan, and the United Kingdom.
  • Sovereign debt refers to the borrowings of a country's government, often issued as bonds.
  • OECD countries have accumulated significant debt due to economic stimulus measures, especially during crises like the COVID-19 pandemic.
  • Challenges of Debt Maturity
  • When a large percentage of debt matures within a short period, governments face liquidity risks.
  • Refinancing this debt might require issuing new bonds at higher interest rates, increasing the cost of borrowing.
  • Failure to address these challenges could lead to debt distress or even default in extreme cases.
  • Global Debt Report
  • The Global Debt Report is a comprehensive analysis that provides insights into global debt levels, trends, and risks.
  • It is used by policymakers, economists, and financial institutions to understand and manage debt-related challenges.

CodeDBAMLECQDPRBUK

 

ConditionsDescription
1. If the first element is a symbol and the last a numberCodes for these two (the first and the last elements) are to be interchanged.
2. If the first element is an odd number and the last an even numberFirst and last elements are to be coded as ©.
3. If both second and third elements are perfect squaresThe third element is to be coded as the code for the second element.

 

Now, the group of numbers and symbols is: @ 3 5 7

Let's analyze the elements of the group:

  • First element: '@' (Symbol)
  • Second element: '3' (Odd number, not a perfect square)
  • Third element: '5' (Odd number, not a perfect square)
  • Last element: '7' (Odd number)

Checking the conditions:

  • Condition 1: "If the first element is a symbol and the last a number, the codes for these two (the first and the last elements) are to be interchanged."
  • The first element ('@') is a symbol. (True)
  • The last element ('7') is a number. (True)
  • Condition 1 applies. The codes for '@' and '7' will be interchanged.
  • Condition 2: "If the first element is an odd number and the last an even number, the first and last elements are to be coded as ©."
  • The first element ('@') is not an odd number. (False)
  • Condition 2 does not apply.
  • Condition 3: "If both second and third elements are perfect squares, the third element is to be coded as the code for the second element."
  • The second element ('3') is not a perfect square. (False)
  • The third element ('5') is not a perfect square. (False)
  • Condition 3 does not apply.

Applying the applicable condition:

Only Condition 1 applies. We will interchange the codes for the first and last elements.

  • Original code for '@' is 'B'.
  • Original code for '7' is 'P'.

After interchange:

  • New code for '@' will be 'P'.
  • New code for '7' will be 'B'.

The codes for '3' and '5' remain as per the table, as no other conditions apply to them.

  • Code for '3' is 'C'.
  • Code for '5' is 'M'.

Therefore, the code for '@ 3 5 7' is → 'P C M B'.

Hence, the correct answer is "Option 4"$.

  2. BOption (b)

    200

  3. COption (c)

    230

  4. DOption (d)

    210

View answer & explanation

Correct answer

Answer: (d)D.

210

Why this answer is correct

Shortcut Trick Loss of 20% means SP1 is 80% of CP. Gain of 50% means SP2 is 150% of CP. Ratio of SPs = 80 : 150 = 8 : 15. Given 8 units = ₹112 ⇒ 1 unit = 112 ÷ 8 = ₹14. New Selling Price (15 units) = 15 × 14 = ₹210. ∴ The correct answer is ₹210.

Alternate Method Given → Initial SP = ₹112, Loss = 20%, Desired Gain = 50%. Formulas: CP = SP × 100 ÷ (100 − Loss%) | New SP = CP × (100 + Gain%) ÷ 100.

⇒ Step 1: Find Cost Price (CP) = 112 × 100 ÷ (100 − 20) = 112 × 100 ÷ 80 = ₹140. ⇒ Step 2: Find New SP for 50% gain = 140 × (100 + 50) ÷ 100. ⇒ New SP = 140 × 150 ÷ 100 = 14 × 15 = ₹210. ∴ The correct answer is ₹210.

Additional Information Cost Price and Selling Price The price at which an article is purchased is CP, and the price it is sold at is SP. If SP > CP, it is a Profit; if SP < CP, it is a Loss. Direct Relation Formula To find new SP when old SP and percentages are known: New SP = (Old SP ÷ (100 − L%)) × (100 + G%).

Question 60

Which principle of citizenship did India start following more strictly after the 2003 Amendment?

  1. AOption (a)

    Jus soli (by birth)

  2. BOption (b)

    Jus sanguinis (by blood)

  3. COption (c)

    Dual citizenship

  4. DOption (d)

    Universal citizenship

View answer & explanation

Correct answer

Answer: (b)B.

Jus sanguinis (by blood)

Why this answer is correct

The Correct answer is Jus sanguinis (by blood).

Key Points

  • After the 2003 Amendment to the Citizenship Act, 1955, India shifted from the principle of jus soli (citizenship by birth) to a stricter application of jus sanguinis (citizenship by descent).
  • The amendment introduced stricter conditions for acquiring Indian citizenship, especially for children born in India to foreign nationals.
  • The focus was shifted to emphasize ancestral ties, meaning citizenship was granted based on the nationality of the parents rather than the place of birth.
  • Under the revised law, a person born in India after December 3, 2004, can only claim Indian citizenship if at least one parent is an Indian citizen and the other parent is not an illegal migrant.
  • The amendment aimed to address concerns over illegal immigration and its impact on demography and national security, especially in border states.
  • The principle of jus sanguinis aligns with the concept of maintaining a closer connection to the nation through family lineage.
  • This change brought India's citizenship laws more in line with countries that prioritize descent-based citizenship, such as Germany and Japan.

 Additional Information

  • Jus soli (by birth)
  • The principle of jus soli grants citizenship to anyone born within a country's territory, regardless of their parents' nationality.
  • Prior to the 2003 Amendment, India followed this principle for granting citizenship. For example, anyone born in India between 1950 and 1987 was automatically considered an Indian citizen.
  • However, concerns over illegal immigration led to restrictions on this principle starting from 1987, and it was further curtailed in the 2003 Amendment.
  • Countries like the United States still follow the principle of jus soli, granting automatic citizenship to anyone born on their soil.
  • Dual citizenship
  • India does not allow dual citizenship. The Citizenship Act, 1955 mandates that Indian citizens must renounce their citizenship if they acquire the citizenship of another country.
  • However, India allows individuals of Indian origin living abroad to obtain an Overseas Citizen of India (OCI) card, which provides certain privileges without granting full citizenship.
  • Dual citizenship is practiced in some countries like Canada and the United Kingdom, allowing individuals to hold citizenship in more than one country simultaneously.
  • Universal citizenship
  • The concept of universal citizenship refers to the idea that all individuals belong to a global community and should have equal rights and opportunities regardless of their country of origin.
  • This concept is more philosophical and is not implemented by any country in its legal framework.
  • It contrasts with the traditional notions of citizenship, which are tied to national borders and sovereignty.

  4. DOption (d)

    22

View answer & explanation

Correct answer

Answer: (d)D.

22

Why this answer is correct

Shortcut Trick Net filling efficiency per minute = (1/8 − 1/11) = 3/88 of the tank. Time to fill full tank = 88/3 minutes. Time to fill 3/4th tank = (88/3) × (3/4) = 22 minutes. ∴ The correct answer is 22 minutes. Alternate Method Given: Filling pipe time = 8 min, Emptying pipe time = 11 min. Formula Used: Total Work = LCM of time taken; Efficiency = Work ÷ Time. Pipe Type Time (min) Total Capacity (LCM) Efficiency Inlet Pipe (+) 8 88 units +11 Outlet Pipe (−) 11 −8 ⇒ Combined efficiency of both pipes = 11 − 8 = 3 units/min. ⇒ Required work = 3/4 of Total Capacity = 3/4 × 88 = 66 units. ⇒ Time required = Required work ÷ Combined efficiency ⇒ Time = 66 ÷ 3 = 22 minutes. ∴ The correct answer is 22 minutes. Additional Information Pipes and Cisterns Convention Inlet pipes that fill the tank are taken as positive efficiency, while outlet pipes that empty the tank are taken as negative efficiency. Net Time Formula If pipe A fills in x hours and pipe B empties in y hours (y > x), net time to fill the tank = (xy) ÷ (y − x). Work and Time Relationship Total Work = Efficiency × Time. For a constant work, efficiency is inversely proportional to time taken.

     54.3

View answer & explanation

Correct answer

Answer: (b)B.

 54.9

Why this answer is correct

Shortcut Trick Apply the Empirical Formula: 3 × Median = Mode + 2 × Mean. 3 × Median = 61.7 + 2 × 51.5 3 × Median = 61.7 + 103 = 164.7 Median = 164.7 ÷ 3 = 54.9 ∴ The correct answer is 54.9. Alternate Method Given: Mean = 51.5, Mode = 61.7 Formula Used: Mode = 3 × Median − 2 × Mean

⇒ 61.7 = 3 × Median − 2 × 51.5 ⇒ 61.7 = 3 × Median − 103 ⇒ 3 × Median = 61.7 + 103 ⇒ 3 × Median = 164.7 ⇒ Median = 164.7 ÷ 3 ⇒ Median = 54.9 ∴ The correct answer is 54.9.

  3. COption (c)

    3525\frac{352}{5} km

  4. DOption (d)

    1726\frac{172}{6} km

View answer & explanation

Correct answer

Answer: (c)C.

3525\frac{352}{5} km

Why this answer is correct

Shortcut Trick

Ratio of Downstream Speed to Upstream Speed = 22 : 5.5 = 4 : 1.

Since Distance is constant for one way, Time ratio = Inverse of speed ratio = 1 : 4.

Total time units = 1 + 4 = 5 units → 8 hours. So, 1 unit = 8/5 hours.

One-way distance = Speed × Time = 22 × (8/5) = 176/5 km.

Total distance (Round trip) = 2 × (176/5) = 352/5 km.

∴ The correct answer is 352/5 km.

Alternate Method

Given:

Downstream speed (D) = 22 km/hr

Upstream speed (U) = 5.5 km/hr

Total time (T) = 8 hours

Formula Used:

Total Time = (Distance / Downstream Speed) + (Distance / Upstream Speed)

Calculations:

⇒ Let the one-way distance be d.

⇒ (d / 22) + (d / 5.5) = 8

⇒ (d / 22) + (2d / 11) = 8

⇒ (d + 4d) / 22 = 8

⇒ 5d / 22 = 8

⇒ 5d = 176

⇒ d = 176/5 km

⇒ Total distance travelled = 2 × d = 2 × (176/5) = 352/5 km

∴ The correct answer is 352/5 km.

Additional Information

Speed in Still Water and Current

Speed of boat in still water (u) = (D + U) / 2 and speed of current (v) = (D − U) / 2.

Average Speed for Round Trip

Average speed for the entire journey = (2 × D × U) / (D + U). Total Distance = Average Speed × Total Time.

Relative Speed Concept

Downstream speed includes the velocity of the stream helping the boat, whereas upstream speed is against the stream.

    3

View answer & explanation

Correct answer

Answer: (a)A.

 36

Why this answer is correct

Shortcut Trick

Interest for 1 month is simply the percentage of the principal for that period.

Simple Interest (SI) = 3% of ₹1,200

SI = (3 ÷ 100) × 1,200

SI = 3 × 12 = 36

∴ The correct answer is ₹36.

Alternate Method

Given:

Principal (P) = ₹1,200

Rate of interest (R) = 3% per month

Time (T) = 1 month

Formula Used:

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

Calculations:

⇒ SI = (1,200 × 3 × 1) ÷ 100

⇒ SI = (3,600) ÷ 100

⇒ SI = 36

∴ The correct answer is ₹36.

Additional Information

Total Amount Formula

The total amount (A) after interest is the sum of the principal and simple interest: A = P + SI.

Annual vs Monthly Rate

If the rate is given annually and time in months, divide the annual rate by 12 or convert time to years (T/12).

Simple Interest Nature

Simple interest remains constant for every equal time period as it is always calculated on the original principal.

View answer & explanation

Correct answer

Answer: (b)B.

65 : 59

Why this answer is correct

Shortcut Trick

Assume the third number is 100.

First number = 100 + 30% of 100 = 130.

Second number = 100 + 18% of 100 = 118.

Ratio = 130 : 118 = 65 : 59.

∴ The correct answer is 65 : 59.

Why this answer is correct

The Correct answer is Sandhara type.

Key Points

  • The Neeramankara Temple, located in Nemam, Kerala, is known to be built in the Sandhara type of shrine architecture.
  • The term Sandhara refers to a type of temple layout in which the structure is enclosed by walls and has a circumambulatory path (pradakshina patha) around the sanctum (garbhagriha).
  • Such temples are designed to allow devotees to perform pradakshina (circumambulation) of the deity housed in the sanctum.
  • This architectural style is commonly found in Indian temple architecture, particularly in regions where cultural and religious practices emphasize circumambulation as an integral part of worship.
  • The Neeramankara Temple reflects the traditional Kerala temple architecture, with its unique wooden carvings, sloped roofs, and intricate design elements.
  • The temple is a significant spiritual and cultural center in the region, drawing devotees and architecture enthusiasts alike.
  • Sandhara temples often include additional features such as mandapas (pillared halls) and ornamental gateways, enhancing the aesthetic and functional aspects of the shrine.

 Additional Information

  • Sarvatobhadra type
  • The Sarvatobhadra type of temple architecture is characterized by its symmetry and accessibility from all directions.
  • This type of temple often has entrances on all four sides, symbolizing the universal accessibility of the deity housed within.
  • It is commonly found in North Indian temple architecture.
  • Unlike the Sandhara type, it may or may not have a circumambulatory path.
  • Mandapa type
  • A Mandapa is a pillared hall or pavilion used for religious purposes, particularly in Hindu temples.
  • It is typically situated in front of the sanctum and serves as a place for devotees to gather and participate in rituals.
  • While Mandapas are part of temple complexes, they are not a standalone architectural style like Sandhara or Sarvatobhadra.
  • Nirandhara type
  • The Nirandhara type of temple is characterized by the absence of a circumambulatory path around the sanctum.
  • It focuses solely on the central sanctum and does not include space for devotees to perform pradakshina.
  • These temples are typically smaller and emphasize direct worship of the deity without circumambulation.

    91193\frac{91}{193}

  4. DOption (d)

    91185\frac{91}{185}

View answer & explanation

Correct answer

Answer: (a)A.

91180\frac{91}{180}

Why this answer is correct

Shortcut Trick

Let HCF = x. Since the ratio of the numbers is 18 : 5, their LCM = 18 × 5 × x = 90x.

Product of LCM and HCF = 90x × x = 90x2 = 360 ⇒ x2 = 4 ⇒ x = 2.

So, HCF = 2 and LCM = 180.

Sum of their reciprocals = (1 / 180) + (1 / 2) = (1 + 90) / 180 = 91 / 180.

∴ The correct answer is 91/180.

Alternate Method

Given:

Ratio of two numbers = 18 : 5

Product of their LCM and HCF = 360

Formula Used:

For two numbers in ratio a : b (where a and b are coprime) with HCF = x, LCM = a × b × x.

Ratio = 18 : 5

Numbers: 18x and 5x

HCF = x

LCM = 18 × 5 × x = 90x LCM × HCF = 90x² = 360

Calculations:

⇒ Let the two numbers be 18x and 5x.

⇒ Since 18 and 5 are coprime to each other, their highest common factor (HCF) is x.

⇒ The least common multiple (LCM) of 18x and 5x = 18 × 5 × x = 90x.

⇒ Given, product of LCM and HCF = 360.

⇒ 90x × x = 360

⇒ 90x2 = 360

⇒ x2 = 360 ÷ 90 = 4

⇒ x = √4 = 2

⇒ Therefore, HCF = 2 and LCM = 90 × 2 = 180.

⇒ Sum of reciprocals of LCM and HCF = (1 / LCM) + (1 / HCF)

⇒ Sum of reciprocals = (1 / 180) + (1 / 2)

⇒ Sum of reciprocals = (1 + 90) / 180 = 91 / 180.

∴ The correct answer is 91/180.

Additional Information

Relationship between HCF, LCM and Product of Numbers

For any two numbers A and B, the product of the numbers is equal to the product of their HCF and LCM. Formula: A × B = HCF × LCM.

Numbers from Ratio

If two numbers are in the ratio a : b, then the numbers can be represented as (a × HCF) and (b × HCF). Here, a and b are strictly co-prime terms.

HCF and LCM of Fractions

HCF of fractions = (HCF of Numerators) ÷ (LCM of Denominators). Similarly, LCM of fractions = (LCM of Numerators) ÷ (HCF of Denominators).

  4. DOption (d)

    144

View answer & explanation

Correct answer

Answer: (c)C.

134

Why this answer is correct

Given interchange rules:

  • ‘+’ and ‘−’ are interchanged.
  • ‘×’ and ‘÷’ are interchanged.

The given equation is:

87 × 3 ÷ 4 + 12 − 30 = ?

  2. BOption (b)

    ₹74.45

  3. COption (c)

    ₹72.91

  4. DOption (d)

    ₹74.26

View answer & explanation

Correct answer

Answer: (b)B.

₹74.45

Why this answer is correct

Shortcut Trick

For Pen 1: MP = 100 × 1.15 = 115. SP = 115 × (1 − 0.29) = 115 × 0.71 = 81.65.

Profit/Loss 1 = 81.65 − 100 = −18.35.

For Pen 2: Profit 2 = 160 × 58% = 160 × 0.58 = 92.80.

Total Profit = 92.80 − 18.35 = 74.45.

∴ The correct answer is ₹74.45.

Alternate Method

Given: CP1 = ₹100, Profit% applied for MP = 15%, Discount = 29%, CP2 = ₹160, Profit%2 = 58%.

Formulas: SP = CP × (100 + P%)/100 | Final SP = MP × (100 − D%)/100 | Profit = Total SP − Total CP.

⇒ Step 1: Calculate marked price for the first pen. MP1 = 100 + (15% of 100) = ₹115.

⇒ Step 2: Calculate selling price for the first pen after discount. SP1 = 115 − (29% of 115) = 115 − 33.35 = ₹81.65.

⇒ Step 3: Calculate selling price for the second pen. SP2 = 160 + (58% of 160) = 160 + 92.8 = ₹252.8.

⇒ Step 4: Calculate total Cost Price and total Selling Price. Total CP = 100 + 160 = ₹260. Total SP = 81.65 + 252.8 = ₹334.45.

⇒ Step 5: Calculate total Profit. Profit = 334.45 − 260 = ₹74.45.

∴ The correct answer is ₹74.45.

Additional Information

Marked Price and Discount

Marked Price is the price listed by the seller. Discount is always calculated on the Marked Price to arrive at the Selling Price: SP = MP × (100 − Discount%)/100.

Profit Calculation

Profit is the difference between the Selling Price and the Cost Price. If SP is less than CP, it results in a loss.

View answer & explanation

Correct answer

Answer: (d)D.

1

Why this answer is correct

Shortcut Trick

For any quadratic equation of the form y2 − (Sum of roots)y + (Product of roots) = 0, we can directly identify the values.

From the given equation y2 − 9y + 8 = 0, the Sum of roots (α + β) is 9 and the Product of roots (αβ) is 8.

The required value is (α + β) − αβ → 9 − 8 = 1.

∴ The correct answer is 1.

Alternate Method

Given: The quadratic equation is y2 − 9y + 8 = 0, where α and β are the roots.

Formula: For a standard quadratic equation ay2 + by + c = 0:

Sum of roots (α + β) = −b/a

Product of roots (αβ) = c/a

Comparing the given equation with the standard form:

⇒ a = 1

⇒ b = −9

⇒ c = 8

Calculating the sum and product:

⇒ α + β = −(−9)/1 = 9

⇒ αβ = 8/1 = 8

Substituting into the expression α + β − αβ:

⇒ Value = 9 − 8

⇒ Value = 1

∴ The correct answer is 1.

Additional Information

Nature of Roots

The nature is determined by the discriminant D = b2 − 4ac. If D > 0, roots are real and distinct; if D = 0, roots are real and equal; if D < 0, roots are imaginary.

Formation of Equation

If roots are known, the equation is formed as: y2 − (Sum of roots)y + (Product of roots) = 0.

Quadratic Formula

The roots can be found using y = [−b ± √(b2 − 4ac)] / 2a.

Why this answer is correct

The Correct answer is Windows displays an error: "A file with this name already exists."

Key Points

  • When a user attempts to rename a file to the same name as an existing file in the same folder on Windows, the operating system checks if there is already a file with that name.
  • If a file with the same name exists, Windows prevents the renaming action by displaying an error message, which reads: "A file with this name already exists."
  • This mechanism ensures that no two files in the same folder have the same name, as it would lead to conflicts in file management.
  • File names in Windows are used as unique identifiers within a folder, and duplication is not allowed.
  • The error helps maintain the file system integrity and avoids overwriting or unintended data loss.
  • To rename a file successfully, users must ensure that the new file name is unique within the folder.
  • This feature is applicable to all Windows versions and is a fundamental rule of file management systems.

View answer & explanation

Correct answer

Answer: (c)C.

 3.27

Why this answer is correct

Shortcut Trick

B = 2 + 4 + 6 = 12

For third proportional C of 44 and 12: C = 122 ÷ 44

C = 144 ÷ 44 = 36 ÷ 11 ≈ 3.27

∴ The correct answer is 3.27.

Alternate Method

Given: First value = 44, Second value = B, Third proportional = C.

Formula Used: If a, b, c are in continued proportion, then c = b2 ÷ a.

⇒ First three even natural numbers are 2, 4, and 6.

⇒ B = 2 + 4 + 6 = 12

⇒ 44, 12, C are in continued proportion.

⇒ 44/12 = 12/C

⇒ C = (12 × 12) ÷ 44

⇒ C = 144 ÷ 44 = 3.2727...

⇒ C ≈ 3.27

∴ The correct answer is 3.27.

  1. AOption (a)

    165.4

  2. BOption (b)

    164.4

  3. COption (c)

    165

  4. DOption (d)

    164

View answer & explanation

Correct answer

Answer: (b)B.

164.4

Why this answer is correct

Shortcut Trick

Let the base average of the class be 163 cm.

The remaining 35 boys have an average height of 165 cm, which is +2 cm more than the base average.

Total positive deviation = 35 × 2 = +70 cm.

This excess deviation must be distributed equally among all 50 boys.

Average increase = 70 ÷ 50 = +1.4 cm.

Overall Average = 163 + 1.4 = 164.4 cm.

∴ The correct answer is 164.4 cm.

Alternate Method

Given:

Total number of boys in the class = 50

Average height of 15 boys = 163 cm

Average height of the remaining boys (50 − 15 = 35) = 165 cm

Formula Used:

Combined Average = (n1x1 + n2x2) ÷ (n1 + n2)

163 15 Boys (Ratio 3)

165 35 Boys (Ratio 7)

164.4 Combined Avg

Distance = 7 parts (1.4 cm)

3 parts (0.6 cm)

Calculations:

⇒ Total sum of heights of 15 boys = 15 × 163 = 2445 cm

⇒ Total sum of heights of remaining 35 boys = 35 × 165 = 5775 cm

⇒ Total sum of heights of all 50 boys = 2445 + 5775 = 8220 cm

⇒ Average height of the entire class = Total Sum ÷ Total Boys

⇒ Average height = 8220 ÷ 50 = 164.4 cm

∴ The correct answer is 164.4 cm.

Additional Information

Weighted Average Concept

When groups of different sizes have different averages, the combined average is shifted closer to the average of the larger group. The distance from the individual averages is inversely proportional to their group sizes.

Alligation Method for Averages

Averages can be solved quickly using alligation cross-difference. The ratio of the quantity of the groups is equal to the ratio of the cross differences of their averages from the mean average: (A2 − Amean) : (Amean − A1) = n1 : n2.

Deviation Method

Instead of calculating large sums, assume a base average (usually the smallest value). Find the net deviation for the remaining quantities, and divide by the total number of items to get the average change to apply to the base.

Question 93

The average of three numbers is 23. If two of them are 11 and 26, the third number is:

  1. AOption (a)

    33

  2. BOption (b)

    32

  3. COption (c)

    31

  4. DOption (d)

    34

View answer & explanation

Correct answer

Answer: (b)B.

32

Why this answer is correct

Shortcut Trick

Total of three numbers = Average × 3 = 23 × 3 = 69.

Sum of two given numbers = 11 + 26 = 37.

Third number = Total − Sum of two numbers = 69 − 37 = 32.

∴ The correct answer is 32.

Alternate Method

Given: Average = 23, Number of terms (n) = 3, Number1 = 11, Number2 = 26.

Formula Used: Average = (Sum of all numbers) ÷ (Number of terms)

⇒ Let the third number be x.

⇒ Average = (11 + 26 + x) ÷ 3

⇒ 23 = (37 + x) ÷ 3

⇒ 23 × 3 = 37 + x

⇒ 69 = 37 + x

⇒ x = 69 − 37

⇒ x = 32

∴ The correct answer is 32.

Additional Information

Net Deviation Method

In any set of numbers, the sum of deviations from the average is always zero. Deviation = (Number − Average).

Arithmetic Progression (AP) Average

For numbers in AP, the average is simply the middle term (if n is odd) or the average of the first and last terms.

Weighted Average

When combining two groups with averages A1 and A2 and sizes n1 and n2, the combined average is (n1A1 + n2A2) ÷ (n1 + n2).

Question 96

A retailer offers the following discount schemes for buyers on an article.

I. Two successive discounts of 27%.

II. A discount of 36% followed by a discount of 45%.

    II

  2. BOption (b)

    III

  3. COption (c)

    IV

  4. DOption (d)

    I

View answer & explanation

Correct answer

Answer: (c)C.

IV

Why this answer is correct

Shortcut Trick

To obtain the maximum selling price, the total discount percentage must be the minimum.

For two successive discounts a% and b%, the net discount = a + b − (a × b) ÷ 100.

Scheme I: 27 + 27 − 7.29 = 46.71% | Scheme II: 36 + 45 − 16.2 = 64.8%.

Scheme III: 19 + 32 − 6.08 = 44.92% | Scheme IV: 34 + 7 − 2.38 = 38.62%.

The lowest discount is in Scheme IV (38.62%), resulting in the highest Selling Price.

∴ The correct answer is Scheme IV.

Alternate Method

Given → Four different successive discount schemes. We need to find the one with the maximum SP. Formulas: Net Discount% = a + b − (ab ÷ 100) | SP = MP × (100 − Net Discount%) ÷ 100.

⇒ Scheme I: 27 + 27 − (27 × 27 ÷ 100) = 54 − 7.29 = 46.71%. ⇒ Scheme II: 36 + 45 − (36 × 45 ÷ 100) = 81 − 16.2 = 64.8%. ⇒ Scheme III: 19 + 32 − (19 × 32 ÷ 100) = 51 − 6.08 = 44.92%. ⇒ Scheme IV: 34 + 7 − (34 × 7 ÷ 100) = 41 − 2.38 = 38.62%. ⇒ Since 38.62% is the minimum discount, it fetches the maximum selling price.

∴ The correct answer is Scheme IV.

Additional Information

Relationship between Discount and SP

For a fixed Marked Price (MP), the Selling Price (SP) is inversely proportional to the discount offered. Higher discount means lower SP, and lower discount means higher SP.

Successive Discounts

When multiple discounts are offered one after another, the net discount is always less than the simple sum of individual discount percentages.

  4. DOption (d)

    51.48

View answer & explanation

Correct answer

Answer: (d)D.

51.48

Why this answer is correct

Shortcut Trick

For a hemisphere of radius r to be fully fitted inside a cuboid, the minimum dimensions of the cuboid must be 2r × 2r × r.

Volume of Cuboid = 2r × 2r × r = 4r3 = 4 × 33 = 108 cm3.

Volume of Hemisphere = (2/3) × π × r3 = (2/3) × 3.14 × 27 = 56.52 cm3.

Water Volume = 108 − 56.52 = 51.48 cm3.

∴ The correct answer is 51.48 cm3.

Alternate Method

Given: Radius of hemisphere (r) = 3 cm, π = 3.14.

Formula Used: Volume of water = Volume of Cuboid − Volume of Hemisphere

⇒ Minimum Length of cuboid = 2 × r = 6 cm

⇒ Minimum Breadth of cuboid = 2 × r = 6 cm

⇒ Minimum Height of cuboid = r = 3 cm

⇒ Volume of Cuboid = 6 × 6 × 3 = 108 cm3

⇒ Volume of Hemisphere = (2/3) × 3.14 × (3)3

⇒ Volume of Hemisphere = 2 × 3.14 × 9 = 56.52 cm3

⇒ Volume of water = 108 − 56.52 = 51.48 cm3

∴ The correct answer is 51.48 cm3.

Additional Information
