Given:

Amount after 2 years (A₁) = ₹4,620

Amount after 2.5 years (A₂) = ₹4,725

Time difference = 0.5 years

Formula used:

Simple Interest (SI) = Principal x Rate x Time / 100

SI for time difference = A₂ - A₁

Calculations:

$SI = A_2 - A_1 = 4725 - 4620 = 105$

SI for 0.5 years = ₹105

SI for 1 year = $\frac{105}{0.5} = 210$

Principal = A₁ - SI for 2 years

$P = 4620 - 210 \times 2 = 4620 - 420 = 4200$

Annual rate of interest:

$SI = \frac{P \times R \times T}{100}$

$210 = \frac{4200 \times R \times 1}{100}$

⇒ $R = \frac{210 \times 100}{4200} = 5$

∴ The annual percentage rate is 5%.

Given:

Average weight of a class of 15 students = 30 kg

A new student joins and the average weight increases by 1 kg

Formula Used:

Total weight of n students = Average weight × Number of students

Calculation:

Total weight of 15 students = 30 × 15

Total weight of 15 students = 450 kg

New average weight = 30 + 1 = 31 kg

Total weight of 16 students = 31 × 16

Total weight of 16 students = 496 kg

Weight of the new student = 496 - 450

Weight of the new student = 46 kg

The weight of the new student is 46 kg.

Given:

Numbers are 12, 36, and 80.

Formula Used:

$\text{LCM}(a, b) = \frac{a \times b}{\text{GCD}(a, b)}$

For more than two numbers, LCM is calculated iteratively.

Calculation:

First, find the LCM of 12 and 36:

Prime factorization of 12: 2² × 3

Prime factorization of 36: 2² × 3²

LCM of 12 and 36:

⇒ LCM = 2² × 3² = 36

Next, find the LCM of 36 and 80:

Prime factorization of 80: 2⁴ × 5

LCM of 36 and 80:

⇒ LCM = 2⁴ × 3² × 5 = 720

The least common multiple of 12, 36, and 80 is 720.

Given:

Total population = 7,000

Percentage increase in male population = 11%

Percentage increase in female population = 8%

New population = 7,680

Formula used:

New population = Increased male population + Increased female population

Calculations:

Let the number of males = M and females = F

M + F = 7,000

New male population = M × 1.11

New female population = F × 1.08

New population equation:

1.11M + 1.08F = 7680

Substitute M = 7000 - F:

1.11(7000 - F) + 1.08F = 7680

⇒ 7770 - 1.11F + 1.08F = 7680

⇒ 7770 - 7680 = 0.03F

⇒ 90 = 0.03F

⇒ F = $\frac{90}{0.03}$ = 3000

∴ The number of female citizens in the town is 3,000.

Given:

A and B together can complete a work in 24 days.

B alone can complete the work in 48 days.

Formula Used:

Work done by A and B together in 1 day = 1/24

Work done by B in 1 day = 1/48

Work done by A in 1 day = Work done by A and B together in 1 day - Work done by B in 1 day

Calculation:

Work done by A and B together in 1 day = 1/24

Work done by B in 1 day = 1/48

⇒ Work done by A in 1 day = (1/24) - (1/48)

⇒ Work done by A in 1 day = 2/48 - 1/48

⇒ Work done by A in 1 day = 1/48

Time taken by A to complete the work alone = 48 days

The correct answer is option 1.

Given:

60% of X = 40% of Y

Formula Used:

To find the ratio X : Y

Calculation:

60% of X = 40% of Y

⇒ (60/100)X = (40/100)Y

⇒ 60X = 40Y

⇒ X/Y = 40/60

⇒ X/Y = 2/3

The value of X : Y is 2 : 3.

Given:

Selling Price (SP) = ₹24

Profit Percentage = Cost Price (CP)

Formula used:

Profit Percentage = $\frac{\text{Profit}}{\text{CP}} × 100$

Profit = SP - CP

Calculations:

Let CP = x

Profit Percentage = CP = x

$\frac{\text{SP - CP}}{\text{CP}} × 100 = x$

⇒ $\frac{24 - x}{x} × 100 = x$

⇒ $\frac{24 - x}{x} = \frac{x}{100}$

⇒ (24 - x) × 100 = x × x

⇒ 2400 - 100x = x²

⇒ x² + 100x - 2400 = 0

After factorization

⇒ x2  - 20x + 120x - 2400 = 0

(x – 20) (x + 120) = 0

x = 20 and -120

Since CP cannot be negative So, CP = 20

∴ The purchase price of the notebook is ₹20.

Given:

Principal (P) = ₹5,19,500

Rate of Interest (R) = $7\frac{4}{5}$ = $\frac{39}{5} = 7.8$ = 0.078

Time (T) = 2 years

Let each installment = x

Formula used:

Total Instalments = Principal + 1st Year Interest + 2nd Year Interest

Compound Interest Formula:

CI = P × R × T

Where:

P = Principal

R = Rate of Interest

T = Time

Calculations:

1st Year Compound Interest:

CI₁ = 5,19,500 × 0.078 = 40,521

Remaining principal after the 1st instalment:

P_remaining = 5,19,500 + 40,521 - x = 5,60,021 - x

2nd Year Compound Interest:

CI₂ = (5,60,021 - x) × 0.078

CI₂ = 43,681.638 - 0.078x

Total Instalment Equation:

2x = 5,19,500 + 40,521 + 43,681.638 - 0.078x

2x + 0.078x = 6,03,702.638

2.078x = 6,03,702.638

$x = \frac{6,03,702.638}{2.078} = 2,90,521$

∴ The equal annual installment is ₹2,90,521.

Given:

Numbers: 16.81 and 12.96

Formula Used:

Mean Proportional = √(a × b)

Calculation:

Let a = 16.81 and b = 12.96

Mean Proportional = √(16.81 × 12.96)

⇒ Mean Proportional = √(217.4976)

⇒ Mean Proportional = 14.76

The mean proportional of 16.81 and 12.96 is 14.76.

Given:

Distance between two places = 88 km

Time to meet (first case) = 8 hours

Akash's speed = a

Vikas's speed = v

In second case:

Akash's speed = $\frac{7}{6}a$

Vikas's speed = $3v$

Time to meet (second case) = 4 hours

Formula used:

Total Distance = Relative Speed × Time

Calculations:

In the first case:

$(a + v) \times 8 = 88$

⇒ $(a + v) = \frac{88}{8} = 11$

In the second case:

$(\frac{7}{6}a + 3v) \times 4 = 88$

⇒ $(\frac{7}{6}a + 3v) = \frac{88}{4} = 22$

Substituting $a + v = 11$ into the second equation:

⇒ $\frac{7}{6}a + 3(11 - a) = 22$

⇒ $\frac{7}{6}a + 33 - 3a = 22$

⇒ $-\frac{11}{6}a + 33 = 22$

⇒ $-\frac{11}{6}a = 22 - 33 = -11$

⇒ $a = \frac{6 \times 11}{11} = 6$

Substitute $a = 6$ into $a + v = 11$:

⇒ $6 + v = 11$

⇒ $v = 5$

∴ Akash's speed = 6 km/h, Vikas's speed = 5 km/h.

Given:

External radius (R_ext) = 10.5 cm

Internal radius (R_int) = 7.7 cm

Density of the metal (ρ) = 10.3 g/cm³

π = 22/7

Formula Used:

Volume of a sphere = $\frac{4}{3} \pi r^3$

Volume of the hollow sphere = Volume of external sphere - Volume of internal sphere

Mass = Density × Volume

Calculation:

Volume of external sphere (V_ext)

⇒ V_ext = $\frac{4}{3} \pi (10.5)^3$

⇒ V_ext = $\frac{4}{3} \times \frac{22}{7} \times 1157.625$

⇒ V_ext = 4852.5 cm³

Volume of internal sphere (V_int)

⇒ V_int = $\frac{4}{3} \pi (7.7)^3$

⇒ V_int = $\frac{4}{3} \times \frac{22}{7} \times 456.533$

⇒ V_int = 1980 cm³

Volume of the hollow sphere (V)

⇒ V = V_ext - V_int

⇒ V = 4852.5 - 1980

⇒ V = 2872.5 cm³

Mass (m)

⇒ m = ρ × V

⇒ m = 10.3 × 2872.5

⇒ m = 29587.75 g

Convert g to kg

⇒ m = 29587.75 / 1000

⇒ m ≈ 29.6 kg

Rounded off to the nearest tens, mass = 30 kg

The mass of the sphere is 30 kg.

Given:

Numbers to find HCF of: 620 and 248.

Formula Used:

Euclidean Algorithm: HCF(a, b) = HCF(b, a mod b)

Calculation:

Step 1: Apply Euclidean Algorithm:

⇒ 620 mod 248 = 124

Step 2: Apply Euclidean Algorithm again:

⇒ 248 mod 124 = 0

The HCF of 620 and 248 is 124.

Given:

Area of the base of the cone = 25π cm²

Height of the cone = 12 cm

Formula Used:

Curved Surface Area (CSA) of a cone = π × r × l

where r = radius of the base, l = slant height

Slant height, l = √(r² + h²)

Calculation:

Area of the base = π × r² = 25π

⇒ r² = 25

⇒ r = √25

⇒ r = 5 cm

Slant height, l = √(r² + h²)

⇒ l = √(5² + 12²)

⇒ l = √(25 + 144)

⇒ l = √169

⇒ l = 13 cm

Curved Surface Area (CSA) = π × r × l

⇒ CSA = π × 5 × 13

⇒ CSA = 65π cm²

The curved surface area of the cone is 65π cm².

Given:

First number: 3² × 4² × 9

Second number: 3³ × 4⁴ × 9¹⁰

Formula used:

HCF is calculated by taking the smallest powers of common prime factors.

Note: 9 = 3².

Calculation:

Rewrite the numbers in terms of prime factors:

First number = 3² × 4² × (3²) = 3⁴ × 2⁴

Second number = 3³ × 4⁴ × (3²⁰) = 3²³ × 2⁸

HCF = Take the smallest powers of 3 and 2:

For 3: min(4, 23) = 4

For 2: min(4, 8) = 4

HCF = 3⁴ × 2⁴

HCF = 81 × 16 = 1296

∴ The HCF is 1296.

Given:

Marked price = ₹500

First seller's discounts = 10% and 20%

Second seller's discount = 30%

Formula Used:

Selling Price = Marked Price - Discount

Calculation:

First Seller's Calculation:

First discount: 10% of ₹500

⇒ 10% × ₹500 = ₹50

Price after first discount: ₹500 - ₹50

⇒ ₹450

Second discount: 20% of ₹450

⇒ 20% × ₹450 = ₹90

Selling price after second discount: ₹450 - ₹90

⇒ ₹360

Second Seller's Calculation:

30% discount on ₹500

⇒ 30% × ₹500 = ₹150

Selling price after 30% discount: ₹500 - ₹150

⇒ ₹350

Difference between their selling prices:

⇒ ₹360 - ₹350

⇒ ₹10

The difference between their selling prices is ₹10.
