The correct answer is Convergent and divergent boundaries.

Key Points

• Volcanoes are commonly found at convergent plate boundaries: At these boundaries, one tectonic plate is subducted beneath another. The subducted plate melts due to intense heat and pressure, leading to magma formation. This magma rises to the Earth's surface, forming volcanoes. Example: The Pacific Ring of Fire is a prominent area of volcanic activity caused by convergent boundaries.
• Divergent plate boundaries also host volcanic activity: At divergent boundaries, tectonic plates move apart, creating gaps where magma from the mantle can rise and solidify. This process forms new crust and is associated with volcanic activity, particularly under oceans. Example: The Mid-Atlantic Ridge is a classic site of volcanic activity at divergent boundaries.
• Transform boundaries typically do not cause volcanic activity: At transform boundaries, plates slide past each other horizontally without significant magma formation. Hence, volcanoes are rarely associated with transform boundaries.
• Volcanoes are not restricted to plate boundaries: They can also occur at hotspots, which are areas of intense heat in the mantle that melt the crust to create volcanic activity. Example: The Hawaiian Islands are formed due to a hotspot and not at any plate boundary.
• Global distribution of volcanoes: Volcanoes are concentrated in areas where tectonic activity is prominent, such as subduction zones, rift zones, and hotspots. Approximately 75% of the world's volcanoes are found in the Pacific Ring of Fire.

Additional Information

• Convergent plate boundaries:
• These occur where plates move towards each other, causing subduction or collision.
• Subduction leads to intense pressure and heat, resulting in magma formation and volcanic activity.
• Example: The Andes mountain range in South America is formed due to subduction of the oceanic plate beneath the continental plate.
• Divergent plate boundaries:
• These occur where plates move apart, allowing magma to rise and form new crust.
• Volcanoes at divergent boundaries are typically less explosive compared to those at convergent boundaries.
• Example: The volcanic activity along the East African Rift Valley is due to divergent boundary processes.
• Transform plate boundaries:
• These occur where plates slide past each other horizontally.
• Volcanic activity is generally absent due to the lack of significant magma formation.
• Example: The San Andreas Fault in California is a famous transform boundary with no volcanic activity.
• Hotspots and intraplate volcanism:
• Hotspots are areas of mantle upwelling that cause volcanic activity away from plate boundaries.
• Example: Yellowstone National Park in the USA is a hotspot known for its geothermal activity and potential for large-scale volcanic eruptions.
• Hotspot volcanoes can form island chains as the tectonic plate moves over the stationary hotspot, creating sequential volcanic activity.

Shortcut Trick

For a tower of height H, if the angles of elevation from two points at distances d₁ and d₂ from its base are complementary, the height is given directly by H = √(d₁ × d₂).

Given the distances from the base are d₁ = b² m and d₂ = a² m.

Applying the formula, height of the tower H = √(b² × a²) = ab.

∴ The correct answer is ab.

Alternate Method

X Y Top (T) Base (B) b² m a² m h

θ

90° - θ

Given:

Distance of point X from the base of the tower, XB = b² m

Distance of point Y from the base of the tower, YB = a² m

Let the height of the vertical tower TB be h.

The angles of elevation at X and Y are complementary. Let the angle at X be θ and the angle at Y be 90° − θ.

Formula Used:

In a right-angled triangle, tan(θ) = Perpendicular ÷ Base

Calculations:

In right-angled ΔTBX:

⇒ tan(θ) = TB ÷ XB

⇒ tan(θ) = h ÷ b²   ... (Equation 1)

In right-angled ΔTBY:

⇒ tan(90° − θ) = TB ÷ YB

⇒ cot(θ) = h ÷ a²   ... (Equation 2)

Multiplying Equation 1 and Equation 2:

⇒ tan(θ) × cot(θ) = (h ÷ b²) × (h ÷ a²)

⇒ 1 = h² ÷ (a² × b²)

⇒ h² = a²b²

⇒ h = √(a²b²)

⇒ h = ab

∴ The correct answer is ab.

V-BODMAS Concept

An extension of BODMAS where 'V' stands for Vinculum (or bar). If a mathematical bar is present over an expression, that part must be evaluated before moving on to any brackets.

Bracket Solving Order

Nested brackets should always be solved from the innermost to the outermost boundary in this exact sequential order: small (), curly {}, and then square [].

Shortcut Trick

Since the distance is constant, the ratio of time taken is inversely proportional to the ratio of speeds.

Ratio of speeds (Prashant : Nisha) = 117 : 48 = 39 : 16

Ratio of time (Prashant : Nisha) = 16 : 39

Given Prashant takes 16 hours, this precisely matches the 16 units of time.

Thus, the time taken by Nisha is 39 units = 39 hours.

∴ The correct answer is 39 hours.

Alternate Method

Given:

Speed of Prashant = 117 km/hr

Time taken by Prashant = 16 hours

Speed of Nisha = 48 km/hr

Formula Used:

Distance = Speed × Time

Time = Distance ÷ Speed

Delhi Kanpur

Prashant (117 km/hr, 16 hrs)

Nisha (48 km/hr, ? hrs)

Calculations:

⇒ Total distance from Delhi to Kanpur = 117 × 16

⇒ Total distance = 1872 km

⇒ Time taken by Nisha = Total distance ÷ Speed of Nisha

⇒ Time taken by Nisha = 1872 ÷ 48

⇒ Time taken by Nisha = 39 hours

∴ The correct answer is 39 hours.

Additional Information

Relative Speed

When two bodies move in the same direction, Relative Speed = S₁ − S₂. When moving in opposite directions, Relative Speed = S₁ + S₂.

Average Speed

For equal distances covered at speeds S₁ and S₂, Average Speed = (2 × S₁ × S₂) ÷ (S₁ + S₂). For varying distances, Average Speed = Total Distance ÷ Total Time.

Unit Conversion

To convert km/hr to m/s, multiply the speed value by 5 ÷ 18. To convert m/s to km/hr, multiply the speed value by 18 ÷ 5.

Rate = 5% = 1/20. Let Principal = (20)² = 400 units.

1st year CI = 20 units, 2nd year CI = 20 + 1 = 21 units.

Given 2nd year CI = ₹2,352 ⇒ 21 units = 2352 ⇒ 1 unit = 112.

Principal = 400 × 112 = ₹44,800.

∴ The correct answer is ₹44,800.

Alternate Method

Given:

Rate of Interest (R) = 5% per annum

Compound Interest for 2nd year (I₂) = ₹2,352

Principal (P)

1st Year CI (I₁) 5% of P

2nd Year CI (I₂) ₹ 2,352

I₂ = I₁ × 1.05

Formula Used:

Interest for 2nd year = Interest for 1st year + Interest on 1st year's interest

Simple Interest for 1st year = (Principal × Rate × Time) ÷ 100

Calculations:

⇒ Let I₁ be the interest for the first year.

⇒ I₂ = I₁ + (5% of I₁) = 1.05 × I₁

⇒ 1.05 × I₁ = 2352

⇒ I₁ = 2352 ÷ 1.05 = ₹2,240

⇒ Since 1st year interest is 5% of the Principal (P):

⇒ 5% of P = 2240

⇒ P × (5 ÷ 100) = 2240

⇒ P = 2240 × 20 = ₹44,800

∴ The correct answer is ₹44,800.

Additional Information

Effective Rate of Compound Interest

For 2 years at R% per annum, the effective compound interest rate is (2R + R²/100)% of the principal.

Difference between CI and SI

For 2 years, the difference between Compound Interest and Simple Interest is exactly the interest earned on the 1st year's interest, which equals P(R/100)².

Where 's' is the semi-perimeter: s = (a + b + c) ÷ 2

Calculations:

⇒ s = (82 + 18 + 80) ÷ 2

⇒ s = 180 ÷ 2 = 90 cm

⇒ Area = √(90 × (90 − 82) × (90 − 18) × (90 − 80))

⇒ Area = √(90 × 8 × 72 × 10)

⇒ Area = √(720 × 720)

⇒ Adding the above two equations: 2 × M's profit = 1812

⇒ M's profit = 906

⇒ N's profit = 1359 − 906 = 453

⇒ Profit ratio of M to N = 906 : 453 = 2 : 1

⇒ Let N's capital be x. Then M's capital is x + 46000.

⇒ [(x + 46000) × 3] ÷ [x × 4] = 2 ÷ 1

⇒ 3x + 138000 = 8x

⇒ 5x = 138000

⇒ x = 27600

⇒ Train A starts 2 hours earlier than Train B (from 8:25 AM to 10:25 AM).

⇒ Distance covered by Train A in these 2 hours = 5 × 2 = 10 km

⇒ Remaining distance to be covered together = 35 − 10 = 25 km

⇒ Relative speed of both trains = 5 + 7 = 12 km/h

⇒ Time taken to meet after 10:25 AM = Distance ÷ Relative speed = 25 ÷ 12 hours

⇒ 25 ÷ 12 hours = 2 hours and (1/12) × 60 minutes = 2 hours 5 minutes

⇒ Meeting time = 10:25 AM + 2 hours 5 minutes = 12:30 PM

Divisibility rule of 3: A number is divisible by 3 if the sum of its digits is a multiple of 3.

Sum of digits of 327087 = 3 + 2 + 7 + 0 + 8 + 7 = 27

Since 27 is divisible by 3, the given number 327087 is perfectly divisible by 3.

∴ The correct answer is 3.

Alternate Method

Given:

Number = 327087

Checking the given options:

⇒ Option 1 (5): A number is divisible by 5 if its last digit is 0 or 5. Here, the last digit is 7, so it is not divisible by 5.

⇒ Option 2 (8): A number is divisible by 8 if its last three digits are divisible by 8. The last three digits are 087, which is not perfectly divisible by 8.

⇒ Option 4 (12): A number must be divisible by both 4 and 3 to be divisible by 12. Since the last digit (7) is odd, the number is not divisible by 4, and hence not divisible by 12.

⇒ Option 3 (3): A number is divisible by 3 if the sum of its digits is divisible by 3.

⇒ Sum of digits = 3 + 2 + 7 + 0 + 8 + 7 = 27

In ΔABC, ∠BCA = 180º − (137º + 19º) = 24º.

Since BC || AD, the alternate interior angles are equal ⇒ ∠CAD = ∠BCA = 24º.

In ΔACD, given AC = CD, angles opposite to equal sides are equal ⇒ ∠CDA = ∠CAD = 24º.

Finally, ∠ACD = 180º − (24º + 24º) = 132º.

Calculations:

In ΔABC, the sum of all internal angles is 180º.

⇒ ∠ABC + ∠BAC + ∠BCA = 180º

⇒ 19º + 137º + ∠BCA = 180º

⇒ 156º + ∠BCA = 180º

⇒ ∠BCA = 180º − 156º = 24º

Since BC || AD, the alternate interior angles are equal.

⇒ ∠CAD = ∠BCA = 24º

Now, consider ΔACD. It is given that AC = CD.

Angles opposite to equal sides of a triangle are equal.

No profit or loss means the Selling Price (SP) is equal to the Cost Price (CP) = ₹3,500.

A discount of 20% means the SP is exactly 80% of the Marked Price (MP).

80% of MP = ₹3,500 ⇒ MP = 3500 ÷ 0.8 = ₹4,375.

∴ The correct answer is ₹4,375.

Alternate Method

Given:

Cost Price (CP) = ₹3,500

Discount = 20%

Profit/Loss = Nil

Formula Used:

Selling Price (SP) = CP + Profit (or − Loss)

MP = (SP × 100) ÷ (100 − Discount%)

Marked Price (MP = 100%)

Selling Price (SP = ₹3500)

−20% Discount

80% of MP = ₹3500

Calculations:

⇒ Since there is no profit or loss, the shopkeeper sells the bicycle exactly at the Cost Price.

⇒ Selling Price (SP) = CP = ₹3,500

⇒ We know that SP is calculated after allowing a discount on the Marked Price (MP).

⇒ SP = MP − (20% of MP) = 80% of MP

⇒ 80% of MP = 3500

⇒ (80 ÷ 100) × MP = 3500

⇒ MP = (3500 × 100) ÷ 80

⇒ MP = 350000 ÷ 80

⇒ MP = ₹4,375

∴ The correct answer is ₹4,375.

Additional Information

Marked Price & Discount

Discount is always offered strictly on the Marked Price (MP). The formula to find the Selling Price is SP = MP − Discount, which can also be written as SP = MP × (100 − Discount%) ÷ 100.

Let the present ages of the father and son be F and S. We need to find 'x' years from now when F + x = 2(S + x), which simplifies to x = F − 2S.

From the condition 3 years ago: F − 3 = 2(S − 3) + 24.

Simplifying this directly gives: F − 2S = 21.

Since x = F − 2S, the required number of years 'x' is exactly 21.

∴ The correct answer is 21 years.

Alternate Method

3 Years Ago Present x Years Hence

F − 3 = 2(S − 3) + 24 F − 2S = 21

Ages: F, S

F + x = 2(S + x) x = F − 2S

Substitute to get x = 21

Given:

Three years ago, the father was 24 years older than twice his son's age.

Let the present age of the Father be F and the Son be S.

Formula Used:

Age x years ago = Present Age − x

Age x years hence = Present Age + x

Calculations:

Father's age 3 years ago = F − 3

Son's age 3 years ago = S − 3

According to the given past condition:

⇒ F − 3 = 2 × (S − 3) + 24

⇒ F − 3 = 2S − 6 + 24

⇒ F − 3 = 2S + 18

⇒ F − 2S = 21    ... (Equation 1)

Let after 'x' years, the Father's age be twice the Son's age.

⇒ Father's future age = F + x

⇒ Son's future age = S + x

According to the required condition:

⇒ F + x = 2 × (S + x)

⇒ F + x = 2S + 2x

⇒ x = F − 2S

Substitute the value of (F − 2S) from Equation 1:

⇒ x = 21

∴ The correct answer is 21 years.

Let original cost of a pen be x and a pencil be y.

Given equations: 12x + 7y = 285 and 11(x − 6) + 3(y + 5) = 118 ⇒ 11x + 3y = 169

Using cross-multiplication: x = (285 × 3 − 169 × 7) ÷ (12 × 3 − 11 × 7) = −328 ÷ −41 = 8

Substituting x in the second equation: 11 × 8 + 3y = 169 ⇒ 3y = 81 ⇒ y = 27

Original cost of 2 pens + 2 pencils = 2 × (8 + 27) = 2 × 35 = 70

∴ The correct answer is ₹70.

Alternate Method

Given:

Cost of 12 pens and 7 pencils = ₹285

Cost of 11 pens (decreased by ₹6) and 3 pencils (increased by ₹5) = ₹118

Calculation:

Let the original cost of 1 pen be x and 1 pencil be y.

⇒ 12x + 7y = 285     ... (Equation 1)

After price change, the new cost of a pen = (x − 6) and a pencil = (y + 5)

⇒ 11(x − 6) + 3(y + 5) = 118

⇒ 11x − 66 + 3y + 15 = 118

⇒ 11x + 3y − 51 = 118

⇒ 11x + 3y = 169     ... (Equation 2)

Multiply Equation 1 by 3 and Equation 2 by 7 to eliminate y:

⇒ 36x + 21y = 855     ... (Equation 3)

⇒ 77x + 21y = 1183     ... (Equation 4)

Subtracting Equation 3 from Equation 4:

⇒ 77x − 36x = 1183 − 855

⇒ 41x = 328

⇒ x = 328 ÷ 41 = 8

Substitute the value of x in Equation 2:

⇒ 11(8) + 3y = 169

⇒ 88 + 3y = 169

⇒ 3y = 169 − 88 = 81

⇒ y = 81 ÷ 3 = 27

The original cost of a pen is ₹8 and a pencil is ₹27.

Now, calculate the required original cost of 2 pens and 2 pencils:

⇒ Cost = 2x + 2y = 2(8) + 2(27)

⇒ Cost = 16 + 54 = 70

∴ The correct answer is ₹70.

Therefore, the difference in amount = 1/2 × Total Amount

Required difference = 658 ÷ 2 = 329

∴ The correct answer is ₹329.

Alternate Method

Given:

Total amount = ₹658

Ratio of shares = 18 : 12 : 2

Formula Used:

Share Difference = (Difference in ratio parts / Total ratio parts) × Total Amount

Total Amount = ₹658 (32 Parts)

18 Parts Largest Share

12 Parts

2 Min

Largest - Smallest = 18 - 2 = 16 Parts Difference = 16 / 32 × ₹658 = ₹329

Calculation:

⇒ Sum of all ratio parts = 18 + 12 + 2 = 32

⇒ Largest share part = 18

⇒ Smallest share part = 2

⇒ Difference in parts = 18 − 2 = 16

⇒ Required difference = (16 / 32) × 658

⇒ Required difference = (1 / 2) × 658

⇒ Required difference = 329

∴ The correct answer is ₹329.

Additional Information

Ratio Distribution

When a quantity N is divided in the ratio a : b : c, the share of the first part is calculated as (a / (a + b + c)) × N.

Difference in Shares

Instead of calculating individual shares and subtracting, directly calculate the difference in ratio parts and divide by the total ratio parts.

Proportion

An equality of two ratios is called a proportion. If a : b = c : d, then a × d = b × c (Product of extremes = Product of means).

Compound Ratio

For two ratios a : b and c : d, their compound ratio is obtained by multiplying the corresponding parts: (a × c) : (b × d).
