When multiple spheres are melted to form a single sphere, the Conservation of Volume applies.

Sum of cubes of individual radii = Cube of the resulting radius (R³ = r₁³ + r₂³ + r₃³).

R³ = 6³ + 8³ + 10³

R³ = 216 + 512 + 1000 = 1728

R = 12 cm (Since 12 × 12 × 12 = 1728).

∴ The correct answer is 12 cm.

Alternate Method

Given:

Radius of 1st sphere (r₁) = 6 cm

Radius of 2nd sphere (r₂) = 8 cm

Radius of 3rd sphere (r₃) = 10 cm

Formula Used:

Volume of a sphere = (4/3) × π × r³

Calculations:

⇒ Total Volume of 3 spheres = Volume of single large sphere

⇒ (4/3)πr₁³ + (4/3)πr₂³ + (4/3)πr₃³ = (4/3)πR³

⇒ (4/3)π × (6³ + 8³ + 10³) = (4/3)πR³

⇒ 6³ + 8³ + 10³ = R³

⇒ 216 + 512 + 1000 = R³

Given:

Akash can finish a work in 18 days

Navin can finish the same work in 36 days

Formula used:

Work done by Akash in 1 day = 1/18

Work done by Navin in 1 day = 1/36

Total work done by Akash and Navin in 1 day = 1/18 + 1/36

Portion of work done by Navin = (Work done by Navin in 1 day) / (Total work done by Akash and Navin in 1 day)

Calculation:

Work done by Akash in 1 day = 1/18

Work done by Navin in 1 day = 1/36

Total work done by Akash and Navin in 1 day = 1/18 + 1/36

⇒ Total work done by Akash and Navin in 1 day = (2 + 1)/36

⇒ Total work done by Akash and Navin in 1 day = 3/36

⇒ Total work done by Akash and Navin in 1 day = 1/12

Portion of work done by Navin = (1/36) / (1/12)

⇒ Portion of work done by Navin = (1/36) × (12/1)

⇒ Portion of work done by Navin = 12/36

⇒ Portion of work done by Navin = 1/3

Selling Price for profit = \(\text{CP} \times (1 + \text{Profit %})\)

Calculation:

CP = $\dfrac{4800}{1 - \dfrac{20}{100}}$

⇒ CP = $\dfrac{4800}{0.8}$

⇒ CP = ₹6,000

Selling Price for profit = $\text{CP} \times (1 + \dfrac{12}{100})$

⇒ Selling Price = $6000 \times 1.12$

⇒ Selling Price = ₹6,720

∴ The correct answer is option (3).

Successive Percentage Increase for 3 years at 3% per year.

Effective rate for 3 years = 3 + 3 + 3 + (3×3 + 3×3 + 3×3)/100 + (3×3×3)/10000

Effective rate = 9 + 0.27 + 0.0027 = 9.2727%

Population after 3 years = 75556 × (1 + 9.2727/100) ≈ 75556 × 1.092727

Population ≈ 82562.11 → 82562 (neglecting decimal)

∴ The correct answer is 82562.

Alternate Method

Given:

Current Population (P) = 75,556

Rate of Increase (R) = 3% per annum

Time (n) = 3 years

Formula Used:

A = P × (1 + R/100)ⁿ

Calculations:

⇒ Population after 3 years = 75556 × (1 + 3/100)³

⇒ Population = 75556 × (1.03)³

⇒ Population = 75556 × (1.03 × 1.03 × 1.03)

⇒ Population = 75556 × 1.092727

⇒ Population = 82562.114212

⇒ Neglecting the decimal part, Population = 82562

∴ The correct answer is 82562.

Additional Information

Population Growth Formula

The formula for population growth is identical to the Compound Interest formula: A = P(1 + R/100)ⁿ.

Successive Percentage Change

For two successive changes of a% and b%, the net change is (a + b + ab/100)%.

Aprajita's initial salary = 150% of 6,00,000 = 9,00,000.

New salary after 12% hike = 112% of 9,00,000.

Calculation: 1.12 × 9,00,000 = 10,08,000.

∴ The correct answer is ₹10,08,000.

Alternate Method

Given:

• Sonia's initial salary = ₹6,00,000

• Aprajita's salary = 150% of Sonia's salary

• Hike in Aprajita's salary = 12%

Formula Used:

New Value = Initial Value × (1 + Increase%/100)

Calculations:

⇒ Aprajita's initial annual salary = 150% of 6,00,000

⇒ Initial salary = (150/100) × 6,00,000 = 1.5 × 6,00,000 = ₹9,00,000

⇒ Increment amount = 12% of 9,00,000

⇒ Increment = (12/100) × 9,00,000 = ₹1,08,000

⇒ Aprajita's salary now = 9,00,000 + 1,08,000

⇒ Aprajita's salary now = ₹10,08,000

∴ The correct answer is ₹10,08,000.

Additional Information

Percentage Multiplier

An increase of x% can be directly calculated by multiplying the base value with (1 + x/100). For example, a 12% increase means multiplying by 1.12.

Base Change Rule

Always identify the correct base for percentage calculations. In this problem, 150% was calculated on Sonia's salary, while 12% was calculated on Aprajita's own initial salary.

Successive Percentage Application

When one percentage is applied after another (like a salary being a % of another and then increasing), the net result is the product of their respective multipliers: Final = Base × m₁ × m₂.

Shortcut Trick

Let the two numbers be 33x and 33y, where x and y are coprime ratios.

The sum of their ratios is 594 ÷ 33 = 18.

We need pairs of coprime numbers (x, y) that add up to 18.

The possible coprime pairs summing to 18 are (1, 17), (5, 13), and (7, 11).

Thus, there are exactly 3 such valid pairs.

∴ The correct answer is 3 pairs.

Alternate Method

Given:

HCF of the two numbers = 33

Sum of the two numbers = 594

Formula Used:

If the HCF is H, the numbers can be written as Hx and Hy, where x and y are coprime.

Finding Coprime Pairs for Sum = 18

Pair 1 (1, 17)

Pair 2 (5, 13)

Pair 3 (7, 11) Total 3 Valid Coprime Pairs

Calculations:

⇒ Let the two numbers be 33x and 33y.

⇒ According to the question, 33x + 33y = 594

⇒ 33(x + y) = 594

⇒ x + y = 594 ÷ 33

⇒ x + y = 18

⇒ Now, we need to find all possible pairs of (x, y) that sum to 18 such that their HCF is 1.

⇒ Checking combinations:

⇒ (1, 17) → Coprime (Valid)

⇒ (2, 16) → HCF is 2 (Invalid)

⇒ (3, 15) → HCF is 3 (Invalid)

⇒ (4, 14) → HCF is 2 (Invalid)

⇒ (5, 13) → Coprime (Valid)

⇒ (6, 12) → HCF is 6 (Invalid)

⇒ (7, 11) → Coprime (Valid)

⇒ (8, 10) → HCF is 2 (Invalid)

⇒ (9, 9) → HCF is 9 (Invalid)

⇒ The valid coprime pairs are (1, 17), (5, 13), and (7, 11).

Identify the largest 3-digit number which is 999 and check downward for primality.

999: Divisible by 3 (Sum of digits 9+9+9 = 27).

998: Divisible by 2 (Even number).

997: Not divisible by any prime numbers up to √997 ≈ 31.

Testing 997 with 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31 shows no factors.

∴ The correct answer is 997.

Alternate Method

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.

To find the largest 3-digit prime number, we evaluate numbers starting from 999 downwards:

⇒ Number 999: Sum of digits = 9 + 9 + 9 = 27. Since 27 is divisible by 3, 999 is not prime.

⇒ Number 998: It is an even number ending in 8, so it is divisible by 2. Not prime.

⇒ Number 997: We test for primality by checking divisibility by primes less than √997 ≈ 31.57.

⇒ Primes to check: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31.

⇒ 997 ÷ 7 = 142.42 | 997 ÷ 11 = 90.63 | 997 ÷ 13 = 76.69 | 997 ÷ 17 = 58.64 | 997 ÷ 19 = 52.47.

⇒ Since 997 is not divisible by any of these, 997 is the largest 3-digit prime number.

∴ The correct answer is 997.

Cost price (CP) = SP / (1 + Gain%)

New selling price without discount = MP

New gain% = (New SP - CP) / CP × 100

Calculations:

SP = 9000 × (1 - 0.25)

⇒ SP = 9000 × 0.75 = 6750

CP = 6750 / (1 + 0.08)

⇒ CP = 6750 / 1.08

⇒ CP = 6250

New SP without discount = 9000

New gain% = (9000 - 6250) / 6250 × 100

⇒ New gain% = 2750 / 6250 × 100

⇒ New gain% = 0.44 × 100

⇒ New gain% = 44%

∴ The correct answer is option (1).

Shortcut Trick

Volume of a cone depends on r²h.

Successive increase of 25% (ratio 4 → 5) for three dimensions (r, r, h).

Initial Volume : Final Volume = (4 × 4 × 4) : (5 × 5 × 5) = 64 : 125.

Percentage Increase = (125 − 64) ÷ 64 × 100 = 61 ÷ 64 × 100 = 95.3125%.

∴ The correct answer is 95.31%.

Alternate Method

Given: Increase in radius (r) = 25%, Increase in height (h) = 25%.

Formula Used: Volume of Cone (V) = 1/3 × π × r² × h

⇒ Let initial radius = r and initial height = h.

⇒ Initial Volume (V₁) = 1/3 × π × r² × h

⇒ New radius (r') = r + 0.25r = 1.25r

⇒ New height (h') = h + 0.25h = 1.25h

⇒ New Volume (V₂) = 1/3 × π × (1.25r)² × (1.25h)

⇒ V₂ = 1/3 × π × 1.5625r² × 1.25h = 1.953125 × (1/3 × π × r² × h)

⇒ V₂ = 1.953125 × V₁

⇒ % Increase = (V₂ − V₁) ÷ V₁ × 100 = (1.953125 − 1) × 100 = 95.3125%

∴ The correct answer is 95.31%.

Additional Information

Successive Percentage Formula

For two successive changes a% and b%, net change = (a + b + ab/100)%. For three changes, apply the formula twice.

Volume Proportionality

For a cone, V ∝ r²h. If only radius changes by x%, volume changes by (x + x + x²/100)%. If both change, it is a triple successive change.

Curved Surface Area (CSA)

CSA of a cone = πrl, where l = √(r² + h²). If r and h increase by k%, l also increases by k%, and CSA increases by (k + k + k²/100)%.

Given:

P ∶ (Q + R) = 2 ∶ 5

R ∶ (P + Q) = 6 ∶ 7

Formula used:

Let P = 2k and (Q + R) = 5k

Let R = 6m and (P + Q) = 7m

Calculation:

P = 2k

⇒ Q + R = 5k

⇒ Q = 5k - R

R = 6m

⇒ P + Q = 7m

⇒ P = 7m - Q

Given P = 2k, so 2k = 7m - Q

Also, Q = 5k - 6m

⇒ 2k = 7m - (5k - 6m)

⇒ 2k = 7m - 5k + 6m

⇒ 2k + 5k = 13m

⇒ 7k = 13m

⇒ m = (7/13)k

Now, Q = 5k - 6m

⇒ Q = 5k - 6(7/13)k

⇒ Q = 5k - (42/13)k

⇒ Q = (65/13)k - (42/13)k

⇒ Q = (23/13)k

P + R = 2k + 6m

⇒ P + R = 2k + 6(7/13)k

⇒ P + R = 2k + (42/13)k

⇒ P + R = (26/13)k + (42/13)k

⇒ P + R = (68/13)k

⇒ Q ∶ (P + R) = (23/13)k ∶ (68/13)k

⇒ Q ∶ (P + R) = 23 ∶ 68

∴ The correct answer is option (3).

Given:

Given:

Principal (P) = ₹85,000

Rate (R) = 7.5% per annum

Time (T) = 4 years

Formula used:

Simple Interest (SI) = $\dfrac{P \times R \times T}{100}$

Amount (A) = Principal (P) + Simple Interest (SI)

Calculations:

SI = $\dfrac{85,000 \times 7.5 \times 4}{100}$

⇒ SI = $\dfrac{85,000 \times 30}{100}$

⇒ SI = ₹25,500

Amount (A) = ₹85,000 + ₹25,500

⇒ A = ₹1,10,500

∴ The correct answer is option 1.

Given:

Speed of boat in still water (b) = 30 km/h

Downstream distance = 60 km

Upstream distance = 60 km

Total time = 4 hours 30 minutes = 9/2 hours

Formula used:

Downstream speed: d = b + w

Upstream speed: u = b - w

Where w = speed of stream

Calculations:

According to the question:

60/(30 + w) + 60/(30 - w) = 9/2

⇒ 3600 = (9/2) × (900 - w²)

⇒ 900 - w² = 800

⇒ w² = 100

⇒ w = 10

∴ Speed of the stream = 10 km/h.

Given:

Average marks in 5 subjects = 62

Average marks in the first four subjects are 5 less than the marks in the fifth subject

Formula used:

Sum of marks in 5 subjects = Average marks × Number of subjects

Calculations:

Sum of marks in 5 subjects = 62 × 5

⇒ Sum of marks in 5 subjects = 310

Let the marks in the fifth subject be x.

Then, average marks in the first four subjects = x - 5

Sum of marks in the first four subjects = (x - 5) × 4

⇒ Sum of marks in the first four subjects = 4x - 20

Sum of marks in the first four subjects + Marks in the fifth subject = 310

⇒ 4x - 20 + x = 310

⇒ 5x - 20 = 310

⇒ 5x = 310 + 20

⇒ 5x = 330

⇒ x = 330 / 5

⇒ x = 66

∴ The correct answer is 66.
