Question 1

While covering a distance of 39 km, a man noticed that after cycling for 5 hours 5 minutes, the distance covered by him was 54\dfrac{5}{4} of the remaining distance. What was his speed (in km/hr, rounded off to one decimal place)?

  1. AOption (a)

    6.5

  2. BOption (b)

    3.2

  3. COption (c)

    1.9

  4. DOption (d)

    4.3

View answer & explanation

Correct answer

Answer: (d)D.

4.3

Why this answer is correct

Shortcut Trick

Total distance = 39 km. Ratio of Covered Distance to Remaining Distance = 5 : 4.

Total units = 5 + 4 = 9 units → 39 km. Covered distance = (5/9) × 39 = 21.666 km.

Time taken = 5 hours 5 minutes = 5 + 5/60 = 5 + 1/12 = 61/12 hours.

Speed = Distance ÷ Time = 21.666 ÷ (61/12) ≈ 4.26 km/hr.

∴ The correct answer is 4.3 km/hr.

Alternate Method

Given: Total distance = 39 km, Time = 5 hours 5 minutes, Covered distance = 5/4 × Remaining distance.

Let the remaining distance be x km.

⇒ Covered distance = 5x/4 km.

⇒ Total Distance = 5x/4 + x = 9x/4

⇒ 9x/4 = 39

⇒ x = (39 × 4) ÷ 9 = 156/9 = 52/3 km.

⇒ Covered Distance = 39 − 52/3 = (117 − 52)/3 = 65/3 km.

⇒ Time = 5 hours + 5/60 hours = 305/60 = 61/12 hours.

⇒ Speed = Distance ÷ Time = (65/3) ÷ (61/12) = (65/3) × (12/61) = 260/61 km/hr.

⇒ Speed ≈ 4.262 km/hr ≈ 4.3 km/hr.

∴ The correct answer is 4.3 km/hr.

Additional Information

Speed, Distance, and Time Relationship

The basic formula is Speed = Distance ÷ Time. Ensure all units are consistent (e.g., km and hours) before calculation.

Unit Conversion

To convert minutes to hours, divide by 60. To convert km/hr to m/s, multiply by 5/18.

Rounding Off Rules

If the second decimal digit is 5 or more, increase the first decimal digit by 1. Here, 4.26 becomes 4.3.

  1. AOption (a)

    ₹25 lakh crore

  2. BOption (b)

    ₹15 lakh crore

  3. COption (c)

    ₹20 lakh crore

  4. DOption (d)

    ₹10 lakh crore

View answer & explanation

Correct answer

Answer: (d)D.

₹10 lakh crore

Why this answer is correct

The Correct answer is ₹10 lakh crore.

Key Points

  • The Asset Monetization Plan 2025-30 is a continuation of the government’s initiative to unlock value from its public sector assets and reinvest the proceeds in new infrastructure projects.
  • The plan focuses on raising ₹10 lakh crore through the monetization of core assets in sectors like transportation, energy, and urban infrastructure.
  • Monetization is carried out by leasing or selling assets, while the ownership of land and other strategic assets remains with the government.
  • This initiative aligns with the government’s broader objective of fostering economic growth and infrastructure development.
  • The revenue generated from this plan will be reinvested into new projects under the National Infrastructure Pipeline (NIP), which aims to modernize and expand India’s infrastructure.
  • The focus is on public-private partnerships (PPPs), which help bring private sector efficiency and expertise to the management of these assets.
  • The government had earlier announced the National Monetization Pipeline (NMP) for 2021-24, and this plan is an extension of that initiative.
  • Through this plan, the government aims to achieve fiscal consolidation while boosting infrastructure investment.

Additional Information

  • ₹25 lakh crore
  • This amount might be considered for larger-scale plans or a longer timeline, but for the 2025-30 Asset Monetization Plan, the focus is on ₹10 lakh crore.
  • ₹15 lakh crore
  • Although plausible for other government initiatives, this is not the allocated amount for the Asset Monetization Plan 2025-30.
  • ₹20 lakh crore
  • Similar to the above, this amount does not correspond to the specified plan but could be part of a different financial strategy or target.

Question 3

If a2+b2=132\mathrm{a^2+b^2=132} and a×b=36\mathrm{a×b=36}, then find (a−b)(a+b)\mathrm{\frac{(a-b)}{(a+b)}}, where a>b.\mathrm{a>b.}

  1. AOption (a)

    1117\sqrt{\frac{11}{17}}

  2. BOption (b)

    511\sqrt{\frac{5}{11}}

  3. COption (c)

    1737\sqrt{\frac{17}{37}}

  4. DOption (d)

    517\sqrt{\frac{5}{17}}

View answer & explanation

Correct answer

Answer: (d)D.

517\sqrt{\frac{5}{17}}

Why this answer is correct

Shortcut Trick

Calculate the square of the difference: (a − b)2 = (a2 + b2) − 2ab = 132 − 72 = 60.

Calculate the square of the sum: (a + b)2 = (a2 + b2) + 2ab = 132 + 72 = 204.

Find the ratio of these squares: ((a − b)/(a + b))2 = 60 / 204 = 5 / 17.

Take the square root to find the required value: (a − b) / (a + b) = √(5 / 17).

∴ The correct answer is √5/17.

Alternate Method

Given: a2 + b2 = 132, ab = 36, and a > b.

Formula Used: (a − b)2 = a2 + b2 − 2ab and (a + b)2 = a2 + b2 + 2ab

⇒ First, we find the numerator (a − b):

⇒ (a − b)2 = a2 + b2 − 2ab = 132 − 2(36) = 132 − 72 = 60

⇒ Since a > b, (a − b) = √60

⇒ Next, we find the denominator (a + b):

⇒ (a + b)2 = a2 + b2 + 2ab = 132 + 2(36) = 132 + 72 = 204

⇒ Assuming (a + b) is positive, (a + b) = √204

⇒ The required ratio is (a − b) / (a + b):

⇒ ((a − b) / (a + b)) = √60 / √204 = √(60 / 204)

⇒ Simplifying the fraction: 60 / 204 = (60 ÷ 12) / (204 ÷ 12) = 5 / 17

⇒ Ratio = √(5 / 17) = √5 / √17

∴ The correct answer is √5/17.

Additional Information

Algebraic Identity for Product

The relationship between the sum, difference, and product of two numbers is given by: (a + b)2 − (a − b)2 = 4ab.

Sum of Squares Identity

The sum of the squares of the sum and difference is: (a + b)2 + (a − b)2 = 2(a2 + b2).

Square Root of Fractions

When taking the square root of a ratio, √(x/y) = √x / √y, where y ≠ 0.

  3. COption (c)

    Six Writs

  4. DOption (d)

    Seven Writs

View answer & explanation

Correct answer

Answer: (b)B.

Five Writs

Why this answer is correct

The Correct answer is Five Writs.

Key Points

  • The Constitution of India empowers the Supreme Court (under Article 32) and the High Courts (under Article 226) to issue five types of writs for the enforcement of Fundamental Rights.
  • The five writs mentioned in the Constitution are:
  • Habeas Corpus: A writ to produce a person detained or imprisoned before the court to examine the legality of their detention.
  • Mandamus: A writ issued to a public official, body, corporation, or government to perform a duty they are legally obligated to perform.
  • Prohibition: A writ directed at a lower court or tribunal, preventing it from exceeding its jurisdiction or acting contrary to the law.
  • Certiorari: A writ by which a higher court orders a lower court or tribunal to transfer a case for review or quashes its decision if it acted beyond its jurisdiction.
  • Quo Warranto: A writ to challenge the legality of a person holding a public office without proper authority.
  • These writs are significant tools to ensure the protection of Fundamental Rights under Part III of the Indian Constitution.
  • The Supreme Court's power to issue writs is primarily for the enforcement of Fundamental Rights, making it a guardian of these rights.
  • The High Courts, however, have a broader jurisdiction and can issue writs for other legal rights in addition to Fundamental Rights.

Additional Information

  • Four Writs
  • The concept of issuing writs is derived from the English Common Law, which initially included only four primary writs. However, the Indian Constitution explicitly mentions five writs.
  • Four writs would exclude the writ of Quo Warranto, which is essential in ensuring that public offices are not held unlawfully.
  • Six Writs
  • The Indian Constitution does not mention six writs. The concept of writs in India is limited to the five types specifically listed in the Constitution under Article 32 and Article 226.
  • Seven Writs
  • The Constitution of India does not authorize the issuance of seven writs. The writs are limited to the five defined types, and the addition of extra writs is not part of the constitutional framework.

Question 6

A sum of money is to be distributed among A, B, C, and D in the ratio of 10 : 4 : 8 : 5. If C gets ₹24 more than B, how much did A receive?

  1. AOption (a)

    ₹59

  2. BOption (b)

    ₹60

  3. COption (c)

    ₹58

  4. DOption (d)

    ₹63

View answer & explanation

Correct answer

Answer: (b)B.

₹60

Why this answer is correct

Shortcut Trick

Ratio of A : B : C : D = 10 : 4 : 8 : 5

Difference between C and B in units = 8 − 4 = 4 units

Given, 4 units = ₹24 ⇒ 1 unit = ₹6

A's share = 10 units = 10 × ₹6 = ₹60

∴ The correct answer is ₹60.

Alternate Method

Given: Ratio A:B:C:D = 10 : 4 : 8 : 5 and C − B = ₹24

Formula: Value of one unit = (Actual Difference) ÷ (Difference in Ratio parts)

⇒ Let the shares be 10x, 4x, 8x, and 5x.

⇒ 8x − 4x = 24

⇒ 4x = 24

⇒ x = 24 ÷ 4 = 6

⇒ Amount received by A = 10x = 10 × 6 = 60

∴ The correct answer is ₹60.

Additional Information

Concept of Ratio and Proportion

A ratio compares values. To find the actual value, multiply the ratio part by a constant 'x' which represents the value of a single unit.

Total Sum Calculation

Total Sum = (Sum of all ratio parts) × value of one unit. In this case: (10+4+8+5) × 6 = 27 × 6 = ₹162.

Proportional Division

If a sum S is divided in ratio a:b, then first part = [a/(a+b)] × S and second part = [b/(a+b)] × S.

Question 7

The average weight of A, B and C is 45 kg. If the average weight of A and B is 39 kg and that of B and C is 48 kg, then the weight of B (in kg) is:

  1. AOption (a)

    39

  2. BOption (b)

    54

  3. COption (c)

    29

  4. DOption (d)

    49

View answer & explanation

Correct answer

Answer: (a)A.

39

Why this answer is correct

Shortcut Trick

Weight of B = [Sum of (A + B) + Sum of (B + C)] − Sum of (A + B + C)

Weight of B = (2 × 39) + (2 × 48) − (3 × 45)

Weight of B = 78 + 96 − 135 = 174 − 135

Weight of B = 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 = 39 kg

Average weight of B and C = 48 kg

Formula Used:

Sum of values = Average × Number of observations

Calculations:

⇒ Total weight of A + B + C = 3 × 45 = 135 kg

⇒ Total weight of A + B = 2 × 39 = 78 kg

⇒ Total weight of B + C = 2 × 48 = 96 kg

⇒ Sum of (A + B) and (B + C) = 78 + 96 = 174 kg

⇒ This sum can be written as: (A + B + C) + B = 174 kg

⇒ 135 + B = 174

⇒ B = 174 − 135

⇒ B = 39 kg

∴ The correct answer is 39 kg.

Additional Information

Definition of Average

The average is the central value of a set of numbers, calculated by dividing the sum of all values by the total number of values.

Overlap Principle

When two sub-groups (like A&B and B&C) are combined and they share a common member (B), that member is added twice in the total sum of sub-groups.

Deviation Method

Averages can also be solved by checking the net deviation from the actual average. Sum of deviations from the mean is always zero.

View answer & explanation

Correct answer

Answer: (a)A.

308

Why this answer is correct

Shortcut Trick

Check for divisibility by 11 as the volume involves π (22/7).

Option (1) 308: 3 + 8 − 0 = 11 (Divisible by 11)

Option (2) 300: 3 + 0 − 0 = 3 (Not divisible)

Option (3) 307: 3 + 7 − 0 = 10 (Not divisible)

Option (4) 314: 3 + 4 − 1 = 6 (Not divisible)

∴ The correct answer is 308 cm3.

Alternate Method

Given: Total Surface Area (TSA) = 396 cm2, Radius (r) = 7 cm, π = 22/7.

Formula Used: TSA = 2πr(h + r); Volume (V) = πr2h

⇒ 396 = 2 × (22/7) × 7 × (h + 7)

⇒ 396 = 44 × (h + 7)

⇒ h + 7 = 396 ÷ 44 = 9

⇒ h = 2 cm

⇒ Volume = πr2h = (22/7) × 7 × 7 × 2

⇒ Volume = 22 × 7 × 2 = 154 × 2 = 308 cm3

∴ The correct answer is 308 cm3.

Additional Information

  4. DOption (d)

    37°37°

View answer & explanation

Correct answer

Answer: (a)A.

48°48°

Why this answer is correct

Shortcut Trick

In any quadrilateral, the angle formed by the bisectors of two adjacent angles is equal to half the sum of the other two remaining angles.

∠TES = (∠Q + ∠R) ÷ 2

∠TES = (52° + 44°) ÷ 2

∠TES = 96° ÷ 2 = 48°

∴ The correct answer is 48°.

Alternate Method

Given:

In quadrilateral QRST:

∠Q = 52°

∠R = 44°

The bisectors of ∠S and ∠T meet at E.

Formula Used:

The sum of all interior angles of a quadrilateral is 360°.

The sum of all interior angles of a triangle is 180°.

Calculations:

In quadrilateral QRST:

⇒ ∠Q + ∠R + ∠S + ∠T = 360°

⇒ 52° + 44° + ∠S + ∠T = 360°

⇒ 96° + ∠S + ∠T = 360°

⇒ ∠S + ∠T = 360° − 96° = 264°

Dividing both sides by 2:

⇒ (∠S + ∠T) ÷ 2 = 264° ÷ 2 = 132°

⇒ ∠S/2 + ∠T/2 = 132°

Since SE and TE are the angle bisectors of ∠S and ∠T respectively:

⇒ ∠EST = ∠S/2 and ∠ETS = ∠T/2

⇒ ∠EST + ∠ETS = 132°

In triangle TES:

⇒ ∠TES + ∠EST + ∠ETS = 180°

⇒ ∠TES + 132° = 180°

⇒ ∠TES = 180° − 132° = 48°

∴ The correct answer is 48°.

Additional Information

Angle Bisector Theorem in Quadrilaterals

The angle formed by the bisectors of two adjacent angles of a quadrilateral is equal to half the sum of the other two remaining angles. For adjacent angles A and B, the angle of intersection of their bisectors is (∠C + ∠D) ÷ 2.

Sum of Interior Angles

For any n-sided polygon, the sum of interior angles is given by (n − 2) × 180°. For a quadrilateral (n = 4), the sum is always 360°.

Opposite Angle Bisectors

The angle between the bisectors of two opposite angles of a quadrilateral is equal to half the difference of the other two angles.

  2. BOption (b)

    ₹3,940

  3. COption (c)

    ₹3,903

  4. DOption (d)

    ₹3,886

View answer & explanation

Correct answer

Answer: (c)C.

₹3,903

Why this answer is correct

Shortcut Trick

Use the ratio formula: CP ÷ MP = (100 − Discount%) ÷ (100 + Gain%).

Ratio CP : MP = (100 − 53) : (100 + 41) = 47 : 141.

Simplify the ratio: 47 : 141 = 1 : 3.

Since 1 unit (CP) = ₹1,301, then 3 units (MP) = 1,301 × 3 = ₹3,903.

∴ The correct answer is ₹3,903.

Alternate Method

Given: Cost Price (CP) = ₹1,301, Discount = 53%, Gain = 41%.

Formulas: SP = CP × (100 + Gain%) ÷ 100 | MP = SP × 100 ÷ (100 − Discount%)

⇒ Selling Price (SP) = 1,301 × (100 + 41) ÷ 100 = 1,301 × 1.41 = ₹1,834.41

⇒ Marked Price (MP) = SP ÷ (1 − 0.53) = 1,834.41 ÷ 0.47

⇒ Marked Price (MP) = ₹3,903

∴ The correct answer is ₹3,903.

Additional Information

Marked Price and Discount

The Marked Price (MP) is the price printed on an item. Discount is always calculated on the MP to arrive at the Selling Price (SP). SP = MP × (100 − D%) / 100.

Relation between CP and MP

When both Profit% and Discount% are known, the direct relation is CP / MP = (100 − D) / (100 + P).

Correct answer

Answer: (c)C.

−1-1

Why this answer is correct

Shortcut Trick

For any cubic equation ax3 + bx2 + cx + d = 0, the product of roots is given by −d/a.

In the given equation kx3 − 5x2 − 12x + k = 0, the coefficient of x3 (a) is k and the constant term (d) is k.

Product of roots = −k ÷ k = −1.

∴ The correct answer is -1.

Alternate Method

Given:

The cubic equation is kx3 − 5x2 − 12x + k = 0.

Formula Used:

For a standard cubic equation ax3 + bx2 + cx + d = 0 with roots α, β, and γ:

Product of roots (αβγ) = −(Constant Term) / (Coefficient of x3) = −d/a

Calculations:

Comparing the given equation kx3 − 5x2 − 12x + k = 0 with ax3 + bx2 + cx + d = 0, we get:

⇒ a = k

⇒ b = −5

⇒ c = −12

⇒ d = k

Now, applying the Vieta's formula for the product of roots:

⇒ Product = −d / a

⇒ Product = −k / k

⇒ Product = −1

∴ The correct answer is -1.

Additional Information

Sum of Roots

For a cubic equation, the sum of roots (α + β + γ) is given by −b/a, which is −(coefficient of x2) ÷ (coefficient of x3).

Sum of Product of Roots Taken Two at a Time

The sum of the products of roots taken in pairs (αβ + βγ + γα) is given by c/a, which is (coefficient of x) ÷ (coefficient of x3).

Quadratic Roots Product

For a quadratic equation ax2 + bx + c = 0, the product of roots is simply c/a.

Degree and Roots

According to the Fundamental Theorem of Algebra, a polynomial of degree n will have exactly n roots (including real and complex roots).

View answer & explanation

Correct answer

Answer: (b)B.

27

Why this answer is correct

Shortcut Trick

Sum of interior angles of a regular polygon with n sides is (n − 2) × 180°.

Given, (n − 2) × 180° = 1260° ⇒ n − 2 = 7 ⇒ n = 9 sides.

Number of diagonals = n × (n − 3) ÷ 2 = 9 × (9 − 3) ÷ 2 = 27.

∴ The correct answer is 27 diagonals.

Alternate Method

Given:

Sum of interior angles of a regular polygon = 1260°

Formula Used:

  1. Sum of interior angles of an n-sided polygon = (n − 2) × 180°
  2. Number of diagonals of an n-sided polygon = n × (n − 3) ÷ 2

Calculations:

Let the number of sides of the regular polygon be n.

⇒ (n − 2) × 180° = 1260°

⇒ n − 2 = 1260° ÷ 180°

⇒ n − 2 = 7

⇒ n = 7 + 2

⇒ n = 9

Thus, the polygon is a regular nonagon (9-sided polygon).

Now, we calculate the number of diagonals:

⇒ Number of diagonals = n × (n − 3) ÷ 2

⇒ Number of diagonals = 9 × (9 − 3) ÷ 2

⇒ Number of diagonals = 9 × 6 ÷ 2

⇒ Number of diagonals = 54 ÷ 2

⇒ Number of diagonals = 27

Option Analysis:

Option (1) 35: If diagonals = 35, then n × (n − 3) ÷ 2 = 35 ⇒ n × (n − 3) = 70 ⇒ n = 10 (decagon). Sum of interior angles would be (10 − 2) × 180° = 1440° ≠ 1260°.

Option (2) 27: This is the correct option as calculated above for a 9-sided polygon (nonagon).

Option (3) 20: If diagonals = 20, then n × (n − 3) ÷ 2 = 20 ⇒ n × (n − 3) = 40 ⇒ n = 8 (octagon). Sum of interior angles would be (8 − 2) × 180° = 1080° ≠ 1260°.

Option (4) 44: If diagonals = 44, then n × (n − 3) ÷ 2 = 44 ⇒ n × (n − 3) = 88 ⇒ n = 11 (hendecagon). Sum of interior angles would be (11 − 2) × 180° = 1620° ≠ 1260°.

∴ The correct answer is 27 diagonals.

Additional Information

Sum of Exterior Angles

The sum of the exterior angles of any convex polygon is always 360°.

Each Interior Angle of a Regular Polygon

For a regular polygon with n sides, each interior angle is equal to ((n − 2) × 180°) ÷ n.

Each Exterior Angle of a Regular Polygon

For a regular polygon with n sides, each exterior angle is equal to 360° ÷ n.

Answer: (c)C.

25

Why this answer is correct

Shortcut Trick

Initial Speed = 23 km/hr for 4.5 hours.

Increased Speed = 23 + 11 = 34 km/hr for 1 hour.

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

Average Speed = [(23 × 4.5) + (34 × 1)] ÷ (4.5 + 1) = (103.5 + 34) ÷ 5.5 = 137.5 ÷ 5.5 = 25 km/hr.

∴ The correct answer is 25 km/hr.

Alternate Method

Given:

Speed1 = 23 km/hr, Time1 = 4.5 hr

Speed2 = 23 + 11 = 34 km/hr, Time2 = 1 hr

Formula Used:

Average Speed = (D1 + D2) ÷ (T1 + T2)

Calculations:

⇒ Distance1 = 23 × 4.5 = 103.5 km

⇒ Distance2 = 34 × 1 = 34 km

⇒ Total Distance = 103.5 + 34 = 137.5 km

⇒ Total Time = 4.5 + 1 = 5.5 hr

⇒ Average Speed = 137.5 ÷ 5.5

⇒ Average Speed = 25 km/hr

∴ The correct answer is 25 km/hr.

Additional Information

Average Speed (Equal Distances)

When a person travels equal distances at speeds x and y, the average speed is 2xy ÷ (x + y).

Relative Speed

If two objects move in the same direction, relative speed = s1 − s2. In opposite directions, relative speed = 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.

View answer & explanation

Correct answer

Answer: (b)B.

Modern Education among Muslims

Why this answer is correct

The Correct answer is Modern Education among Muslims.

Key Points

  • The Aligarh Movement was initiated by Sir Syed Ahmed Khan, an eminent scholar and reformer, during the late 19th century in India.
  • The movement primarily focused on providing modern education to the Muslim community, which lagged behind in educational and socio-economic progress.
  • Sir Syed Ahmed Khan believed that modern education, particularly in the fields of science, technology, and English, was necessary to empower Muslims to compete with other communities in colonial India.
  • He established the Mohammedan Anglo-Oriental College (MAO College) in 1875, which later became Aligarh Muslim University (AMU).
  • The movement emphasized the adoption of Western-style education, which was seen as crucial for the growth and development of Muslims in the colonial era.
  • It aimed to build bridges between the Muslim community and the British authorities, promoting harmony and cooperation.
  • The Aligarh Movement also worked to eliminate prejudices and foster better understanding between different communities in India.
  • The movement's success contributed to the establishment of a modern educational infrastructure for Muslims and inspired many other reform initiatives across India.

Additional Information

  • Women's Rights
  • While the Aligarh Movement did not primarily focus on women's rights, it indirectly contributed to the cause by promoting education, which eventually extended to women.
  • Educational reforms initiated under the movement laid the groundwork for greater awareness regarding women's empowerment and their access to education.
  • Hindu Revivalism
  • Hindu Revivalism was an entirely separate movement that aimed at rejuvenating and promoting Hindu culture, values, and traditions.
  • It was led by reformers such as Swami Dayanand Saraswati and organizations like the Arya Samaj.
  • This movement was not related to the objectives of the Aligarh Movement, which focused on Muslim education.
  • Abolition of Sati
  • The Abolition of Sati was a significant reform led by social reformers like Raja Ram Mohan Roy in the early 19th century.
  • This practice involved the self-immolation of widows on their husbands' funeral pyres, and its abolition in 1829 was one of the key milestones in Indian social reform.
  • While both the abolition of Sati and the Aligarh Movement aimed at societal improvement, their focus and contexts were entirely different.

Question 27

A sells a camera to B at a loss of 60% and B sells the camera to C at a profit of 25%. If C purchased the camera for ₹62,616, then what was the cost (in ₹) of the camera for A?

  1. AOption (a)

    1,25,226

  2. BOption (b)

    1,25,232

  3. COption (c)

    1,25,229

  4. DOption (d)

    1,25,230

View answer & explanation

Correct answer

Answer: (b)B.

1,25,232

Why this answer is correct

Shortcut Trick

Ratio of CP to SP for A is 100 : 40 (60% loss) ⇒ 5 : 2.

Ratio of CP to SP for B is 100 : 125 (25% profit) ⇒ 4 : 5.

Combined ratio (ACP : CCP) = (5 × 4) : (2 × 5) = 20 : 10 = 2 : 1.

Since 1 unit (C's price) = 62,616, then 2 units (A's price) = 62,616 × 2 = 1,25,232.

∴ The correct answer is ₹1,25,232.

Alternate Method

Given → Loss of A = 60%, Profit of B = 25%, Final Price (C) = 62,616. Formulas: SP = CP × (100 − Loss%) ÷ 100 | SP = CP × (100 + Profit%) ÷ 100.

⇒ Let the cost price for A be x.

⇒ B's cost price = x × (100 − 60) ÷ 100 = 0.40x.

⇒ C's cost price = 0.40x × (100 + 25) ÷ 100 = 0.40x × 1.25.

⇒ 62,616 = 0.5x.

⇒ x = 62,616 ÷ 0.5 = 1,25,232.

∴ The correct answer is ₹1,25,232.

Additional Information

Successive Transactions

When an item is sold multiple times, the final cost price can be calculated as Initial CP × (1 ± r1/100) × (1 ± r2/100) ... = Final Price.

Profit and Loss Percentage

Profit% = (Profit ÷ CP) × 100 and Loss% = (Loss ÷ CP) × 100. Both are always calculated on the Cost Price (CP) unless stated otherwise.

  4. DOption (d)

    1087

View answer & explanation

Correct answer

Answer: (d)D.

1087

Why this answer is correct

Shortcut Trick

For any reciprocal algebraic expression, if x + 1/x = k, then x2 + 1/x2 = k2 − 2.

Given: x + 1/x = 33

Here, k = 33.

x2 + 1/x2 = 332 − 2 = 1089 − 2 = 1087.

∴ The correct answer is 1087.

Alternate Method

Given:

x + 1/x = 33

Formula Used:

The Algebraic Identity: (a + b)2 = a2 + 2ab + b2

Calculations:

⇒ x + 1/x = 33

Squaring both sides of the equation:

⇒ (x + 1/x)2 = 332

⇒ x2 + (1/x)2 + 2 × x × (1/x) = 1089

⇒ x2 + 1/x2 + 2 = 1089

⇒ x2 + 1/x2 = 1089 − 2

⇒ x2 + 1/x2 = 1087

∴ The correct answer is 1087.

Additional Information

Negative Reciprocal Identity

If x − 1/x = k, then x2 + 1/x2 = k2 + 2.

Cubic Reciprocal Identity

If x + 1/x = k, then x3 + 1/x3 = k3 − 3k.

    60

  2. BOption (b)

    64

  3. COption (c)

    57

  4. DOption (d)

    62

View answer & explanation

Correct answer

Answer: (d)D.

62

Why this answer is correct

Shortcut Trick

Divide 13874 by 67 and find the remainder.

13874 ÷ 67 → Quotient = 207, Remainder = 5.

Smallest number to be added = Divisor − Remainder.

Value = 67 − 5 = 62.

∴ The correct answer is 62.

Alternate Method

Given: Number = 13874, Divisor = 67.

Formula Used: Required Number to add = Divisor − (Number mod Divisor)

⇒ Long division of 13874 by 67:

⇒ 67 × 2 = 134

⇒ 138 − 134 = 4 (bring down 7 → 47)

⇒ 67 × 0 = 0 (bring down 4 → 474)

⇒ 67 × 7 = 469

⇒ 474 − 469 = 5 (Remainder)

⇒ Smallest number to add = 67 − 5 = 62.

∴ The correct answer is 62.

Additional Information

Division Algorithm

Dividend = (Divisor × Quotient) + Remainder. For exact divisibility, the remainder must be 0.

Number to Subtract

To find the smallest number to subtract to make a number divisible, the answer is simply the Remainder itself.

Divisibility Rule of 67

There is no simple shortcut for 67 as it is a prime number; long division or the (Divisor − Remainder) method is the most efficient.

    3,80,237

View answer & explanation

Correct answer

Answer: (c)C.

3,80,240

Why this answer is correct

Shortcut Trick

Ratio of Selling Prices: Loss 10% ⇒ 90 units and Profit 68% ⇒ 168 units.

Given: 90 units = &rupee;2,03,700.

Value of 1 unit = 2,03,700 ÷ 90 = 2,263.

Required SP = 168 units × 2,263 = &rupee;3,80,184 is not in options, recalculating: 20370 ÷ 9 = 2,263.33...

Multiplier method: SP = (2,03,700 ÷ 90) × 168 = 2,263.33... × 168 = &rupee;3,80,240.

∴ The correct answer is &rupee;3,80,240.

Alternate Method

Formulas: CP = [SP × 100] ÷ [100 − Loss%], New SP = [CP × (100 + Profit%)] ÷ 100.

⇒ Step 1: Find the Cost Price (CP) of the car.

⇒ CP = (2,03,700 × 100) ÷ (100 − 10) = 2,03,700 × 100 ÷ 90 = &rupee;2,26,333.33...

⇒ Step 2: Calculate the New Selling Price for 68% profit.

⇒ New SP = 2,26,333.33... × (168 ÷ 100) = 2,263.33... × 168.

⇒ New SP = &rupee;3,80,240.

∴ The correct answer is &rupee;3,80,240.

Additional Information

Cost Price & Selling Price Relationship

When an object is sold at two different conditions, CP remains constant. Ratio of SP1:SP2 = (100 ± P/L1):(100 ± P/L2).

  4. DOption (d)

    115

View answer & explanation

Correct answer

Answer: (b)B.

100

Why this answer is correct

Shortcut Trick

Effective CI rate for 2 years at 5% = 5 + 5 + (5 × 5) / 100 = 10.25%.

Effective SI rate for 2 years at 5% = 5 × 2 = 10%.

Given, 10.25% corresponds to ₹102.5.

⇒ 10% will correspond to (102.5 ÷ 10.25) × 10 = ₹100.

∴ The correct answer is ₹100.

Alternate Method

Given:

Rate (R) = 5% p.a.

Time (T) = 2 years

Compound Interest (CI) = ₹102.5

Formula Used:

CI = P × [(1 + R/100)T − 1]

SI = (P × R × T) ÷ 100

Calculations:

⇒ 102.5 = P × [(1 + 5/100)2 − 1]

⇒ 102.5 = P × [(1.05)2 − 1]

⇒ 102.5 = P × [1.1025 − 1]

⇒ 102.5 = P × 0.1025

⇒ P = 102.5 ÷ 0.1025 = ₹1000

Now, calculate Simple Interest (SI):

⇒ SI = (1000 × 5 × 2) ÷ 100

⇒ SI = 10000 ÷ 100

⇒ SI = ₹100

∴ The correct answer is ₹100.

Additional Information

Difference between CI and SI

For a period of 2 years, the difference (D) between CI and SI is given by: D = P × (R/100)2.

Effective Rate of Interest

For 2 years, effective CI rate = x + y + (xy/100)%, where x and y are rates for the 1st and 2nd years.

Compound Interest Formula

Amount (A) = P(1 + R/100)n, where CI = A − P.

  2. BOption (b)

    low soil fertility

  3. COption (c)

    low water table

  4. DOption (d)

    high water table

View answer & explanation

Correct answer

Answer: (d)D.

high water table

Why this answer is correct

The Correct answer is high water table.

Key Points

  • Sub-irrigation is a method of irrigation where water is supplied directly to the root zone by raising the water table.
  • This technique is particularly beneficial in areas with a high water table, as it allows plants to access water naturally through capillary action.
  • It minimizes water evaporation and runoff, making it more efficient and environmentally friendly.
  • Regions with a high water table are ideal for sub-irrigation as water is readily available just below the surface.
  • This method reduces the need for complex irrigation infrastructure and is suitable for crops that thrive with consistent moisture levels.
  • India has several regions with high water tables, such as parts of the Indo-Gangetic Plain, where sub-irrigation can be effectively practiced.

Additional Information

  • Sandy soil
  • Sandy soil is characterized by large particles and poor water retention capacity.
  • Sub-irrigation is not effective in sandy soils as water cannot be held near the root zone due to its high permeability.
  • Crops in sandy soils usually require surface or sprinkler irrigation systems for optimal growth.
  • Low soil fertility
  • Low soil fertility refers to the lack of essential nutrients needed for plant growth.
  • This condition is unrelated to the water table and sub-irrigation; it requires soil amendment techniques such as fertilizer application or organic matter incorporation.
  • Low water table
  • Areas with a low water table are unsuitable for sub-irrigation because water is not readily available near the surface.
  • Such regions often require alternative irrigation methods like drip irrigation or canal irrigation.

    ₹280

View answer & explanation

Correct answer

Answer: (c)C.

₹300

Why this answer is correct

Shortcut Trick

Assume a base Average Expenditure of ₹300.

Calculate deviations from ₹300: −50, 0, −25, +25, +50.

Sum of deviations = (−50 + 50) + (−25 + 25) + 0 = 0.

Net change in average = 0 ÷ 5 = 0.

Final Average = 300 + 0 = ₹300.

∴ The correct answer is ₹300.

Alternate Method

Given:

Expenditure on Monday = ₹250

Expenditure on Tuesday = ₹300

Expenditure on Wednesday = ₹275

Expenditure on Thursday = ₹325

Expenditure on Friday = ₹350

Formula Used:

Average = (Sum of all observations) ÷ (Total number of observations)

Calculations:

⇒ Total Expenditure = 250 + 300 + 275 + 325 + 350

⇒ Total Expenditure = ₹1500

⇒ Number of Days = 5

⇒ Average Daily Expenditure = 1500 ÷ 5

⇒ Average Daily Expenditure = ₹300

∴ The correct answer is ₹300.

Additional Information

Arithmetic Mean

The basic average, calculated by dividing the sum of a set of numbers by the count of those numbers. Formula: Average = Σx ÷ n.

Green box

Why this answer is correct

The Correct answer is Green box.

Key Points

  • The PM-KISAN scheme is a direct income support scheme launched by the Government of India to provide financial assistance to farmers.
  • Under the World Trade Organization's (WTO) Agreement on Agriculture, subsidies are classified into different "boxes" based on their impact on trade and production.
  • The Green Box includes subsidies that have minimal or no trade-distorting effects on production and are considered permissible under WTO rules.
  • PM-KISAN falls under the Green Box because it involves direct income transfers to farmers without linking the payments to the production of any specific crop or agricultural output.
  • The scheme provides Rs. 6,000 annually in three equal installments to eligible farmers, ensuring a steady source of income for agricultural households.
  • Green Box subsidies are typically government-funded and do not involve price support, making them compliant with WTO regulations.
  • This classification ensures that the PM-KISAN scheme does not violate international trade norms and supports farmers in a non-discriminatory manner.

Additional Information

  • Red Box
  • Red Box subsidies are prohibited under WTO rules as they have significant trade-distorting effects.
  • These include measures such as export subsidies that directly affect global trade and production.
  • Amber Box
  • Amber Box subsidies are considered trade-distorting but are subject to reduction commitments under WTO.
  • Examples include price support programs and subsidies linked to production levels.
  • Blue Box
  • Blue Box subsidies are a subset of Amber Box but are exempt from reduction commitments under specific conditions.
  • These subsidies are linked to production-limiting programs and aim to reduce overproduction.

Question 47

A tank can be filled by two pipes C and D in 60 minutes and 40 minutes, respectively. How much time will it take to fill the tank from the empty state if D is used for half the time and C and D fill it together for the other half?

  1. AOption (a)

    30 minutes

  2. BOption (b)

    15 minutes

  3. COption (c)

    1 hour

  4. DOption (d)

    50 minutes

View answer & explanation

Correct answer

Answer: (a)A.

30 minutes

Why this answer is correct

Shortcut Trick

Let Total Capacity of the tank be 120 units (LCM of 60 and 40).

Efficiency of Pipe C = 2 units/min and Pipe D = 3 units/min.

Average efficiency for total time T = (Efficiency of D × 0.5) + (Efficiency of C+D × 0.5).

Average efficiency = (3 × 0.5) + (5 × 0.5) = 1.5 + 2.5 = 4 units/min.

Total Time = 120 ÷ 4 = 30 minutes.

∴ The correct answer is 30 min.

Alternate Method

Given: Filling time for Pipe C = 60 min, Pipe D = 40 min.

PersonDaysTotal WorkEfficiency
Pipe C601202
Pipe D403

Let the total time taken to fill the tank be T minutes.

⇒ Time for which only Pipe D works = T/2

⇒ Time for which Pipes C and D work together = T/2

⇒ Work done = (Efficiency of D × T/2) + (Efficiency of C+D × T/2) = 120

⇒ (3 × T/2) + ((2 + 3) × T/2) = 120

⇒ 1.5T + 2.5T = 120

⇒ 4T = 120

⇒ T = 30 min

∴ The correct answer is 30 min.

Additional Information

Pipes and Cisterns Efficiency

The efficiency of a pipe is inversely proportional to the time it takes to fill a tank. Efficiency = Total Work ÷ Time.

Combined Pipe Formula

If two pipes fill a tank in x and y hours, the time taken together is (x × y) ÷ (x + y) hours.

Inlet and Outlet Pipes

Inlet pipes have positive efficiency, while outlet (leakage) pipes have negative efficiency when calculating net flow.

Question 48

Why did Mendeleev leave gaps in his periodic table?

  1. AOption (a)

    For undiscovered elements

  2. BOption (b)

    To make the table look symmetrical

  3. COption (c)

    To include isotopes

  4. DOption (d)

    To avoid repetition of elements

View answer & explanation

Correct answer

Answer: (a)A.

For undiscovered elements

Why this answer is correct

The Correct answer is For undiscovered elements.

Key Points

  • Dmitri Mendeleev, the Russian chemist, is credited with the creation of the first widely recognized periodic table.
  • Mendeleev arranged the elements in order of their increasing atomic weights and grouped them based on similar chemical properties.
  • While arranging, he noticed gaps in the periodic table and intentionally left them for undiscovered elements.
  • He predicted the existence of these elements and their properties, long before they were discovered.
  • Examples of elements discovered later that fit into these gaps include gallium (Ga), scandium (Sc), and germanium (Ge).
  • This approach demonstrated the predictive power of the periodic table and highlighted its importance in understanding chemical behavior.
  • The gaps ensured the periodic table remained organized and followed the periodic law, which states that the properties of elements are periodic functions of their atomic weights (later modified to atomic numbers).

Additional Information

  • To make the table look symmetrical
  • Mendeleev did not leave gaps for aesthetic purposes or symmetry; his focus was on the scientific rationale behind the arrangement of elements.
  • The periodic table's structure is determined by chemical properties and atomic weights (or atomic numbers), not symmetry.
  • To include isotopes
  • Mendeleev's periodic table was based on atomic weight, not isotopes. The concept of isotopes was introduced later by Frederick Soddy in the early 20th century.
  • Isotopes are variants of elements with the same number of protons but different numbers of neutrons, and they were not part of Mendeleev's original table.
  • To avoid repetition of elements
  • Mendeleev's periodic table did not have repetition of elements; each element had a unique place based on its atomic weight and chemical properties.
  • The gaps were for elements yet to be discovered, not to prevent repetition.

Question 49

What is the mode of the following data?

53, 47, 43, 42, 52, 54, 54, 51, 42, 53, 53, 48, 46, 43, 43, 40, 43, 41

    43

  2. BOption (b)

    47

  3. COption (c)

    42

  4. DOption (d)

    53

View answer & explanation

Correct answer

Answer: (a)A.

43

Why this answer is correct

Shortcut Trick

The Mode is simply the value that appears most frequently in a data set.

Scan the data for repetitions: 43 appears 4 times, while 53 appears 3 times.

Other numbers like 42 and 54 appear only 2 times each.

Since 43 has the highest frequency, it is the mode.

∴ The correct answer is 43.

Alternate Method

Given: Data set = {53, 47, 43, 42, 52, 54, 54, 51, 42, 53, 53, 48, 46, 43, 43, 40, 43, 41}

Formula: Mode = Value with the maximum frequency.

To find the mode, we calculate the frequency of each observation:

⇒ Frequency of 40 = 1

⇒ Frequency of 41 = 1

⇒ Frequency of 42 = 2

⇒ Frequency of 43 = 4

⇒ Frequency of 46 = 1

⇒ Frequency of 47 = 1

⇒ Frequency of 48 = 1

⇒ Frequency of 51 = 1

⇒ Frequency of 52 = 1

⇒ Frequency of 53 = 3

⇒ Frequency of 54 = 2

⇒ The observation with the maximum frequency is 43 (frequency = 4).

∴ The correct answer is 43.

Additional Information

Empirical Relationship

For a moderately skewed distribution, the relationship between the three measures of central tendency is: Mode = 3 × Median − 2 × Mean.

Bimodal and Multimodal Data

If two values have the same maximum frequency, the data is bimodal. If more than two values have the same maximum frequency, it is multimodal.

Median

The Median is the middle value when data is sorted. For an even number of observations (n), it is the average of the (n/2)th and (n/2 + 1)th terms.

Correct answer

Answer: (a)A.

15

Why this answer is correct

Given:

60% of 40 and (3/5) of 15

Formula Used:

Percentage calculation: (X% of Y) = (X × Y) / 100

Fraction of a number: (P/Q) × N

Difference = Value 1 - Value 2

Calculation:

60% of 40 = (60 × 40) / 100

⇒ (60 × 40) / 100 = 2400 / 100 = 24

(3/5) of 15 = (3 × 15) / 5

  3. COption (c)

    32

  4. DOption (d)

    16

View answer & explanation

Correct answer

Answer: (a)A.

8

Why this answer is correct

Shortcut Trick

Net efficiency = Filling efficiency − Emptying efficiency.

Let Total Work = LCM(15, 40) = 120 units.

Efficiency: Pipe A = +8, Pipe B = −3 → Combined = +5 units/hr.

Required Work = 1/3 × 120 = 40 units.

Time = 40 ÷ 5 = 8 hours.

∴ The correct answer is 8 hours.

Alternate Method

Given: Filling time = 15 hours, Emptying time = 40 hours.

Formula Used: Efficiency = Total Work ÷ Time; Time = Work ÷ Efficiency.

PipeTime (hrs)Total Capacity (LCM)Efficiency
Filling Pipe15120+8
Emptying Pipe40−3

⇒ Net efficiency of both pipes = 8 − 3 = 5 units/hr.

⇒ Capacity to be filled = 1/3 × 120 = 40 units.

⇒ Time required = 40 ÷ 5 = 8 hours.

∴ The correct answer is 8 hours.

Additional Information

Pipes and Cisterns Concept

Filling pipes have positive efficiency, while outlet or leakage pipes have negative efficiency. Total capacity is typically assumed as the LCM of individual times.

Net Work Formula

If pipe A fills in x hrs and pipe B empties in y hrs, net work done in 1 hr = (1/x − 1/y). Time to fill completely = (xy)/(y − x).

  3. COption (c)

    12%

  4. DOption (d)

    10%

View answer & explanation

Correct answer

Answer: (d)D.

10%

Why this answer is correct

Shortcut Trick

Total Interest Percentage = (Interest ÷ Principal) × 100

Total Interest % = (700 ÷ 1400) × 100 = 50%

Rate of Interest per annum = Total Interest % ÷ Time

Rate (R) = 50% ÷ 5 = 10%

∴ The correct answer is 10%.

Alternate Method

Given:

Principal (P) = ₹1,400

Simple Interest (SI) = ₹700

Time (T) = 5 years

Formula Used:

SI = (P × R × T) ÷ 100

Calculations:

⇒ 700 = (1400 × R × 5) ÷ 100

⇒ 700 = 14 × R × 5

⇒ 700 = 70 × R

⇒ R = 700 ÷ 70

⇒ R = 10%

∴ The correct answer is 10%.

Additional Information

Simple Interest (SI)

It is the interest calculated only on the initial Principal amount for the entire period. Formula: SI = (P × R × T) ÷ 100.

Amount (A)

The total money (Principal + Interest) to be paid back after the time period. Formula: A = P + SI = P(1 + RT ÷ 100).

Rate of Interest (R)

  4. DOption (d)

    Large surface area combined with a thin alveolar-capillary barrier

View answer & explanation

Correct answer

Answer: (d)D.

Large surface area combined with a thin alveolar-capillary barrier

Why this answer is correct

The Correct answer is Large surface area combined with a thin alveolar-capillary barrier.

Key Points

  • The alveoli in the lungs are designed to maximize gas exchange efficiency.
  • Their structure provides a large surface area due to the presence of millions of alveoli, which increases the interface for oxygen and carbon dioxide exchange.
  • The walls of the alveoli are composed of a single layer of thin epithelial cells, which minimizes the diffusion distance for gases.
  • The adjacent capillaries also have thin walls, further facilitating the quick diffusion of gases.
  • The thin alveolar-capillary barrier ensures rapid exchange of oxygen into the blood and carbon dioxide out of the blood.
  • This structure is further supported by a layer of surfactant, which reduces the surface tension of the alveoli and prevents their collapse during exhalation.
  • The combination of large surface area, thin barriers, and proximity of alveoli to capillaries is crucial for maintaining the efficiency of gas exchange.

Additional Information

  • Thick epithelial lining to protect from pathogens
  • While the alveoli have a thin epithelial lining for efficient gas exchange, other parts of the respiratory tract, such as the trachea, have thicker epithelial layers to provide protection from pathogens.
  • These areas are also supported by mucus and cilia to trap and expel foreign particles.
  • Abundance of mucus-secreting cells
  • Mucus-secreting cells are prominent in the upper respiratory tract but are not a feature of alveoli, as mucus would impede gas exchange.
  • Mucus primarily functions to trap dust, debris, and pathogens, preventing them from reaching the delicate alveoli.
  • A robust elastic network to maintain alveolar shape
  • The elastic fibers in the alveoli allow them to expand and recoil during breathing, but this feature alone does not directly enhance gas exchange efficiency.
  • The elastic network supports the structural integrity of the alveoli rather than facilitating gas diffusion.

View answer & explanation

Correct answer

Answer: (b)B.

53.75

Why this answer is correct

Shortcut Trick

Identify the modal class (highest frequency): 50−60 where f1 = 37.

Apply the Mode formula: L + [(f1 − f0) ÷ (2f1 − f0 − f2)] × h

Mode = 50 + [(37 − 34) ÷ (74 − 66)] × 10 = 50 + (3 ÷ 8) × 10

Mode = 50 + 3.75 = 53.75

∴ The correct answer is 53.75 years.

Alternate Method

Given:

Lower limit of modal class (L) = 50

Frequency of modal class (f1) = 37

Frequency of preceding class (f0) = 34

Frequency of succeeding class (f2) = 32

Class width (h) = 10

Formula: Mode = L + [(f1 − f0) ÷ (2 × f1 − f0 − f2)] × h

⇒ Mode = 50 + [(37 − 34) ÷ (2 × 37 − 34 − 32)] × 10

⇒ Mode = 50 + [3 ÷ (74 − 66)] × 10

⇒ Mode = 50 + (3 ÷ 8) × 10

⇒ Mode = 50 + 0.375 × 1

Question 73

A man spends 50% of his monthly salary on the rent of his house. If every month he also spends ₹780 on his conveyance and ₹9,800 on his groceries and saves the remaining ₹110, his monthly salary is:

  1. AOption (a)

  2. BOption (b)

    ₹21,282

  3. COption (c)

    ₹21,380

  4. DOption (d)

    ₹21,430

View answer & explanation

Correct answer

Answer: (c)C.

₹21,380

Why this answer is correct

Shortcut Trick

Let the Monthly Salary be 100%.

Rent = 50%, so the remaining 50% must cover Conveyance, Groceries, and Savings.

Remaining 50% = ₹780 + ₹9,800 + ₹110 = ₹10,690.

If 50% = ₹10,690, then 100% = ₹10,690 × 2 = ₹21,380.

∴ The correct answer is ₹21,380.

Alternate Method

Given:

Rent Expenditure = 50% of Salary

Conveyance = ₹780, Groceries = ₹9,800, Savings = ₹110

Formula: Total Salary = Rent + Conveyance + Groceries + Savings

⇒ Let Total Salary = S

⇒ S = 0.50S + 780 + 9,800 + 110

⇒ S − 0.50S = 10,690

⇒ 0.50S = 10,690

⇒ S = 10,690 ÷ 0.50

⇒ S = ₹21,380

∴ The correct answer is ₹21,380.

Additional Information

Percentage Base Change

When a value is split into percentages, the sum of all parts must equal 100% of the base value.

Savings Formula

Savings = Income − Total Expenditure. In percentage terms: Savings % = 100% − (Sum of all expenditure %).

Successive Percentage

If the question says 'percent of remaining', use the formula: Final = Initial × (1 − r1/100) × (1 − r2/100).

View answer & explanation

Correct answer

Answer: (b)B.

(13, 89, 21)

Why this answer is correct

The logic followed here is:

Logic:  (First Number + Third Number) × 3 - First Number = Second Number.

Let's verify this logic with the given sets:

For, (7, 80, 22)

⇒ (7 + 22) × 3 - 7 = 29 × 3 - 7 = 87 - 7 = 80.

Here, the logic followed.

For, (43, 143, 19)

⇒ (43 + 19) × 3 - 43 = 62 × 3 - 43 = 186 - 43 = 143.

Here, the logic followed.

Now, let's check the options based on this logic:

Option 1) (11, 63, 15)

⇒ (11 + 15) × 3 - 11 = 26 × 3 - 11 = 78 - 11 = 67. (Given Second number is 63, 63 ≠ 67)

Here, logic not followed.

Option 2) (13, 89, 21)

⇒ (13 + 21) × 3 - 13 = 34 × 3 - 13 = 102 - 13 = 89. (Matches)

Here, logic followed.

Option 3) (25, 91, 15)

⇒ (25 + 15) × 3 - 25 = 40 × 3 - 25 = 120 - 25 = 95. (Given Second number is 91, 91 ≠ 95)

Here, logic not followed.

Option 4) (49, 139, 15)

⇒ (49 + 15) × 3 - 49 = 64 × 3 - 49 = 192 - 49 = 143. (Given Second number is 139, 139 ≠ 143)

Here, logic not followed.

Hence, the correct answer is "Option 2".

Question 77

    They were largely made of stone.

  2. BOption (b)

    They were largely made of wood.

  3. COption (c)

    They were largely made of concrete.

  4. DOption (d)

    They were largely made of iron.

View answer & explanation

Correct answer

Answer: (a)A.

They were largely made of stone.

Why this answer is correct

The correct answer is They were largely made of stone.

Key Points

  • The Ashokan pillars are an important part of India's ancient heritage and were largely made of strong and durable polished stone, primarily Chunar sandstone, which was sourced from the region of Uttar Pradesh.
  • These pillars were erected during the reign of Emperor Ashoka in the 3rd century BCE and served as a medium to propagate the teachings of Buddhism and the ethical code of conduct based on his Dhamma.
  • The pillars are known for their remarkable craftsmanship, featuring highly polished surfaces and intricate carvings, including the famous Lion Capital at Sarnath, which is now India's national emblem.
  • Each pillar weighed several tons and often stood between 40 to 50 feet tall, demonstrating advanced engineering skills of the Mauryan era.
  • The inscriptions on these pillars were written in Brahmi script and conveyed messages of moral and ethical guidance, emphasizing non-violence, tolerance, and compassion.
  • The pillars were strategically placed in important locations, such as religious sites, trade routes, and administrative centers, ensuring maximum visibility and impact on the population.

Additional Information

  • They were largely made of wood
  • Wood was not a suitable material for creating structures like Ashokan pillars due to its inability to withstand environmental conditions for centuries. The use of stone ensured durability and permanence.
  • Wood was primarily used for temporary constructions or simple tools during ancient times rather than monumental architecture.
  • They were largely made of concrete
  • Concrete as a construction material was not developed during the Mauryan period, as it became widely used only in modern times, particularly after the Roman invention of concrete in the 2nd century BCE.
  • The Ashokan pillars relied on naturally occurring materials like stone rather than artificially created substances like concrete.
  • They were largely made of iron
  • Iron was used in ancient India for tools and smaller objects, but crafting monumental structures like pillars from iron was not common due to technological limitations.
  • However, ancient India did produce notable iron artifacts like the Iron Pillar of Delhi, which is famous for its rust-resistant properties.

    5090 and 5100

  3. COption (c)

    5070 and 5080

  4. DOption (d)

    5110 and 5130

View answer & explanation

Correct answer

Answer: (d)D.

5110 and 5130

Why this answer is correct

Shortcut Trick

Identify the constant difference: (Divisor − Remainder)

27 − 17 = 10, 19 − 9 = 10, 15 − 5 = 10.

LCM(27, 19, 15) = 1539. Number format: 1539k − 10.

Check multiples for divisibility by 80: For k = 3, (1539 × 3) − 10 = 4617 − 10 = 4607 (No). For k = 10, (1539 × 10) − 10 = 15380 (No).

The number 5120 is divisible by 80. Thus, 5120 lies between 5110 and 5130.

∴ The correct answer is 5110 and 5130.

Alternate Method

Given: Remainder is 17 when divided by 27; 9 when divided by 19; 5 when divided by 15. Remainder is 0 when divided by 80.

⇒ Let the number of marbles be N.

⇒ N = 27a + 17 ⇒ N + 10 = 27(a + 1)

⇒ N = 19b + 9 ⇒ N + 10 = 19(b + 1)

⇒ N = 15c + 5 ⇒ N + 10 = 15(c + 1)

⇒ Therefore, (N + 10) is a multiple of LCM(27, 19, 15).

⇒ LCM(27, 19, 15): 27 = 33, 19 = 19, 15 = 3 × 5.

⇒ LCM = 33 × 19 × 5 = 27 × 95 = 2565.

⇒ N + 10 = 2565k ⇒ N = 2565k − 10.

⇒ Also, N must be divisible by 80. Check values of k:

⇒ If k = 1, N = 2565 − 10 = 2555 (Not divisible by 80).

⇒ If k = 2, N = 2565 × 2 − 10 = 5130 − 10 = 5120.

⇒ Checking divisibility: 5120 ÷ 80 = 64 (Perfectly divisible).

⇒ The value 5120 lies in the range 5110 to 5130.

∴ The correct answer is 5110 and 5130.

Additional Information

LCM Method for Remainders

If a number leaves remainders r1, r2, r3 when divided by d1, d2, d3 such that (d1−r1) = (d2−r2) = (d3−r3) = K, then the number is of form LCM(d1, d2, d3) × n − K.

Divisibility Rule of 80

A number is divisible by 80 if it is divisible by both 8 and 10. This means it must end in 0 and the number formed by the last three digits must be divisible by 8.

    Format Painter

  4. DOption (d)

    Ctrl + Drag

View answer & explanation

Correct answer

Answer: (c)C.

Format Painter

Why this answer is correct

The Correct answer is Format Painter.

Key Points

  • The Format Painter tool in MS Word is not used for moving text but rather for copying formatting from one part of the document to another. It does not serve any function related to text movement.
  • The purpose of the Format Painter is to replicate text styles, font settings, colors, or other formatting properties to a different section of the document.
  • It is a highly useful feature when maintaining consistent formatting across the document.
  • As the question specifically asks for methods of moving selected text, the Format Painter does not qualify since it is unrelated to text relocation.
  • While other options such as Drag and Drop, Cut and Paste, or Ctrl + Drag involve physically moving or duplicating text, the Format Painter is exclusively for formatting purposes.

Additional Information

  • Drag and Drop
  • The Drag and Drop method allows users to move selected text by clicking and dragging it to a new location within the document.
  • This method is highly intuitive and often used for quick rearrangement of text.
  • Cut and Paste
  • The Cut and Paste option involves removing the selected text from its original location and inserting it into a new location.
  • This is accomplished using the commands Ctrl + X (Cut) and Ctrl + V (Paste).
  • It is one of the most common methods for text relocation in MS Word.
  • Ctrl + Drag
  • The Ctrl + Drag option is used to duplicate text while moving it to a different location in the document.
  • Holding down the Ctrl key while dragging text creates a copy instead of simply moving the text.
  • This feature is useful for efficiently duplicating content within the same document.

Question 82

Which among the following is the main reason for classifying economic activities into different sectors in India?

  1. AOption (a)

    To divide labour across sectors

  2. BOption (b)

    To increase taxes across sectors

  3. COption (c)

    To understand their functioning and interdependence

  4. DOption (d)

    To reduce employment in capital-intensive sectors

View answer & explanation

Correct answer

Answer: (c)C.

To understand their functioning and interdependence

Why this answer is correct

The Correct answer is To understand their functioning and interdependence.

Key Points

  • Classifying economic activities into different sectors helps in understanding the structure of an economy.
  • The three main sectors of economic activities are the primary sector (agriculture and natural resources), the secondary sector (manufacturing and industry), and the tertiary sector (services).
  • This classification aids in analyzing the functioning of each sector, such as the production processes, employment patterns, and contribution to GDP.
  • It allows policymakers to understand the interdependence among sectors, such as how the agriculture sector supplies raw materials to industries or how industries support the services sector.
  • This categorization is crucial for identifying strengths and weaknesses within the economy and helps in making decisions on resource allocation, investments, and policy formulation.
  • It provides insights into the changing dynamics of the economy, such as the transition from an agriculture-based economy to an industrial or service-based one.
  • Understanding sectoral interdependence is essential for ensuring sustainable development and addressing issues like unemployment, resource management, and economic growth.
  • This knowledge is particularly significant for a country like India, where the economy is diverse and each sector plays a distinct role in national development.

Additional Information

  • To divide labour across sectors
  • This option suggests dividing labor between sectors, but the classification of economic activities is not primarily aimed at labor division.
  • Labour division depends on factors such as skills, demand, and sectoral growth, and is not the main purpose of categorizing economic activities.
  • To increase taxes across sectors
  • While taxation policies may vary across sectors, the primary purpose of classification is not to increase taxes.
  • Taxation is a policy decision and not directly related to the understanding of sectoral functioning.
  • To reduce employment in capital-intensive sectors
  • This option is misleading, as the classification of economic activities is not aimed at reducing employment in any sector.
  • Instead, the goal is to ensure balanced development and understand the role of each sector in employment generation.

View answer & explanation

Correct answer

Answer: (d)D.

4013401\sqrt3

Why this answer is correct

Shortcut Trick

Given slant height l = 2r, where r is the radius.

Height h = √(l2 − r2) = √((2r)2 − r2) = r√3.

Volume V = (1/3)πr2h ⇒ 401π = (1/3)πr2(r√3).

401 = (r3√3)/3 ⇒ r3 = (401 × 3) / √3 = 401√3.

∴ The correct answer is 401√3 cm3.

Alternate Method

Given:

Slant height (l) = 2 × Radius (r)

Volume of cone (V) = 401π cm3

Formula Used:

Volume of cone = (1/3)πr2h

Relation between l, r, and h: l2 = r2 + h2

Calculations:

⇒ h = √(l2 − r2)

⇒ h = √((2r)2 − r2) = √(4r2 − r2) = √(3r2) = r√3

⇒ Volume = (1/3) × π × r2 × (r√3)

⇒ 401π = (π × r3 × √3) / 3

⇒ 401 = (r3 × √3) / 3

⇒ r3 = (401 × 3) / √3

⇒ r3 = 401√3

∴ The correct answer is 401√3 cm3.

Additional Information

Total Surface Area of Cone

The total surface area is the sum of the curved surface area and the base area: TSA = πrl + πr2 = πr(l + r).

Curved Surface Area (CSA)

The lateral or curved surface area of a cone is given by the formula: CSA = πrl.

Equilateral Triangle Cross-section

When the slant height equals the diameter (l = 2r), the vertical cross-section of the cone through the apex is an equilateral triangle.

Correct answer

Answer: (a)A.

60∘60^\circ

Why this answer is correct

Shortcut Trick

The expression simplifies to 2secθ = 4.

⇒ secθ = 2.

Since sec60° = 2, then θ = 60°.

∴ The correct answer is 60°.

Alternate Method

Given: cosθ1−sinθ+cosθ1+sinθ=4\frac{cos\theta}{1-sin\theta} + \frac{cos\theta}{1+sin\theta}=4

Formula Used: (1 − sin2θ) = cos2θ and secθ = 1/cosθ

⇒ cosθ [ (1 + sinθ + 1 − sinθ) / (1 − sinθ)(1 + sinθ) ] = 4

⇒ cosθ [ 2 / (1 − sin2θ) ] = 4

⇒ 2cosθ / cos2θ = 4

⇒ 2 / cosθ = 4

⇒ 2secθ = 4

⇒ secθ = 2

⇒ θ = 60°

∴ The correct answer is 60°.

Additional Information

View answer & explanation

Correct answer

Answer: (a)A.

125

Why this answer is correct

Shortcut Trick

Recognize that the expression 64x3 + 27y3 + 144x2y + 108xy2 is the expansion of the identity (a + b)3 = a3 + b3 + 3a2b + 3ab2.

Here, a = 4x and b = 3y, so the expression simplifies to (4x + 3y)3.

Substitute x = 5 and y = −5: [4(5) + 3(−5)]3 → (20 − 15)3.

The final value is 53 = 125.

∴ The correct answer is 125.

Alternate Method

Given:

Expression: 64x3 + 27y3 + 144x2y + 108xy2

Values: x = 5, y = −5

Formula Used:

(a + b)3 = a3 + b3 + 3a2b + 3ab2

Calculations:

⇒ 64x3 + 27y3 + 144x2y + 108xy2

⇒ (4x)3 + (3y)3 + 3 × (4x)2 × (3y) + 3 × (4x) × (3y)2

⇒ (4x + 3y)3

Now, substituting the values of x and y:

⇒ [4 × 5 + 3 × (−5)]3

⇒ [20 − 15]3

⇒ (5)3

⇒ 5 × 5 × 5 = 125

∴ The correct answer is 125.

View answer & explanation

Correct answer

Answer: (d)D.

15

Why this answer is correct

Shortcut Trick

Let Anjali's age be A and Kamal's age be K.

Equation 1: 7A − 6K = 14

Equation 2: 7K − 7A = −7 ⇒ 7A − 7K = 7

Subtracting Eq 2 from Eq 1: (7A − 6K) − (7A − 7K) = 14 − 7 ⇒ K = 7 years.

Substitute K=7 in Eq 2: 7A − 7(7) = 7 ⇒ 7A = 56 ⇒ A = 8 years.

Sum = 8 + 7 = 15 years.

∴ The correct answer is 15 years.

Alternate Method

Given:

Condition 1: 7 × Anjali = 6 × Kamal + 14

Condition 2: 7 × Kamal = 7 × Anjali − 7

Calculations:

⇒ From Condition 2: 7K = 7A − 7

⇒ Divide by 7: K = A − 1 ⇒ A − K = 1

⇒ Substitute A = K + 1 in Condition 1:

⇒ 7(K + 1) = 6K + 14

⇒ 7K + 7 = 6K + 14

⇒ 7K − 6K = 14 − 7

⇒ K = 7 years

⇒ A = 7 + 1 = 8 years

⇒ Sum = A + K = 8 + 7 = 15 years

∴ The correct answer is 15 years.
