Given:

Buying rate = 14 pens for ₹1

Selling rate = 12 pens for ₹1

Formula used:

Profit Percentage = ((Selling Price - Cost Price) / Cost Price) × 100

Calculations:

Cost Price of 1 pen = 1 / 14 

Selling Price of 1 pen = 1 / 12 

Profit per pen = Selling Price - Cost Price

⇒ Profit per pen = 1 / 12 - 1 / 14 = ₹ (14 - 12) / 168

Profit Percentage = (2 / 168) / (1 / 14) × 100

⇒ Profit Percentage = 16.66%

∴ The profit percentage is 16.66%.

Given:

What is the value of 8400 ÷ 21 + 42 × 5 - 410?

Formula used:

Use basic arithmetic operations: division (÷), multiplication (×), addition (+), and subtraction (-)

Calculation:

8400 ÷ 21 + 42 × 5 - 410

⇒ 400 + 42 × 5 - 410

⇒ 400 + 210 - 410

⇒ 610 - 410

⇒ 200

∴ The correct answer is option (4).

Given:

A dealer sells two laptops at the rate of ₹10000 per laptop.

On one laptop, he earns a profit of 40%.

On the other laptop, he loses 40%.

Formula used:

Profit or Loss Percentage = $\dfrac{SP - CP}{CP} \times 100$

Calculation:

Let the cost price of the first laptop be C₁ and the cost price of the second laptop be C₂.

For the first laptop:

Selling Price (SP) = ₹10000

Profit = 40%

⇒ SP = C₁ + 0.4C₁

⇒ ₹10000 = 1.4C₁

⇒ C₁ = ₹10000 ÷ 1.4

⇒ C₁ = ₹7142.86

For the second laptop:

Selling Price (SP) = ₹10000

Loss = 40%

⇒ SP = C₂ - 0.4C₂

⇒ ₹10000 = 0.6C₂

⇒ C₂ = ₹10000 ÷ 0.6

⇒ C₂ = ₹16666.67

Total Cost Price (CP):

⇒ CP = C₁ + C₂

⇒ CP = ₹7142.86 + ₹16666.67

⇒ CP = ₹23809.53

Total Selling Price (SP):

⇒ SP = ₹10000 + ₹10000

⇒ SP = ₹20000

Profit or Loss Percentage:

⇒ Profit or Loss = SP - CP

⇒ Profit or Loss = ₹20000 - ₹23809.53

⇒ Profit or Loss = -₹3809.53

⇒ Loss Percentage = $\dfrac{-3809.53}{23809.53} \times 100$

⇒ Loss Percentage = -16%

∴ The dealer incurs a loss of 16% on the whole transaction.

Given:

Average weight of 24 persons = 34 kg

Average weight of 48 persons = K kg

Average weight of all 72 persons = 56 kg

Formula used:

Average weight = $\dfrac{\text{Total weight}}{\text{Number of persons}}$

Calculations:

Let total weight of 24 persons = 24 × 34 = 816 kg

Let total weight of 48 persons = 48 × K = 48K kg

Total weight of 72 persons = 72 × 56 = 4032 kg

So, total weight = 816 + 48K = 4032

⇒ 816 + 48K = 4032

⇒ 48K = 4032 - 816

⇒ 48K = 3216

⇒ K = $\dfrac{3216}{48}$

⇒ K = 67 kg

∴ The correct answer is K = 67 kg.

Given:

Principal (P) = ₹2000

Amount (A) = ₹5920

Formula used:

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

Calculation:

SI = A - P = 5920 - 2000 = ₹3920

Substitute the values in the formula:

3920 = $\dfrac{2000 \times R \times T}{100}$

Since R = T, we can simplify:

3920 = $\dfrac{2000 \times R^2}{100}$

⇒ R² = $\dfrac{3920 \times 100}{2000}$ = 196

⇒ R = √196 = 14

∴ The annual rate of interest is 14%.

Given:

$\dfrac{42}{23} \times \dfrac{46}{7} , of , \dfrac{28}{92} \div \dfrac{21}{69}$

Formula used:

Multiplication and division of fractions: $\dfrac{a}{b} \times \dfrac{c}{d} = \dfrac{a \times c}{b \times d}$

Calculations:

$\dfrac{42}{23} \times \dfrac{46}{7} = \dfrac{42 \times 46}{23 \times 7} = \dfrac{1932}{161} = 12$

Now, $\dfrac{28}{92} = \dfrac{7}{23}$

$\dfrac{21}{69} = \dfrac{7}{23}$

$\dfrac{7}{23} \div \dfrac{7}{23} = 1$

$\dfrac{12 \times 1}{1} = 12$

∴ The correct answer is 12.

Given:

m - n = 11

m² + n² = 141

Formula used:

(m - n)² = m² - 2mn + n²

Calculations:

(m - n)² = 11² = 121

m² + n² = 141

So, $\text{m}^2 + \text{n}^2 - 2\text{mn} = 121$

⇒ 141 - 2mn = 121

⇒ 141 - 121 = 2mn

⇒ 20 = 2mn

⇒ mn = 10

∴ The correct answer is mn = 10.

Shortcut Trick

Direct ratio formula: MP / CP = (100 − Loss%) / (100 − Discount%)

⇒ MP / CP = (100 − 10) / (100 − 25) = 90 / 75 = 6 / 5

Let Cost Price (CP) = 5 units and Marked Price (MP) = 6 units.

If the article is sold at the marked price, Selling Price (SP) = 6 units.

⇒ Profit % = [(6 − 5) / 5] × 100 = (1 / 5) × 100 = 20%

∴ The correct answer is 20%.

Alternate Method

Given:

Discount = 25%

Loss = 10%

Formula Used:

SP = MP × (100 − D%) / 100

SP = CP × (100 − L%) / 100

Calculations:

⇒ Let the Marked Price (MP) be 100 units.

⇒ Selling Price (SP) after 25% discount = 100 − 25 = 75 units.

⇒ Since there is a 10% loss, SP = CP × (100 − 10) / 100

⇒ 75 = CP × 0.9

⇒ CP = 75 / 0.9 = 250 / 3 units.

⇒ If the article is sold at the Marked Price, New SP = 100 units.

⇒ Profit = New SP − CP = 100 − 250/3 = (300 − 250) / 3 = 50 / 3 units.

⇒ Profit % = (Profit / CP) × 100

⇒ Profit % = [(50 / 3) / (250 / 3)] × 100 = (50 / 250) × 100 = 20%

∴ The correct answer is 20%.

Additional Information

Direct Relation between CP and MP

The ratio of Cost Price to Marked Price is directly derived from profit/loss and discount percentages: CP / MP = (100 − Discount%) / (100 ± Profit or Loss%).

Successive Discounts

When two successive discounts of D₁% and D₂% are applied on an article, the single equivalent discount is calculated as: D₁ + D₂ − (D₁ × D₂) / 100.

Dishonest Dealer

If a dealer claims to sell goods at Cost Price but uses a false weight, the actual profit percentage is given by: [(True Weight − False Weight) / False Weight] × 100.

Shortcut Trick

The Income Ratio of Ramesh and Suresh is 3 : 4 and their Expenditure Ratio is 2 : 3.

Since the difference between income and expenditure units is the same (3 − 2 = 1 and 4 − 3 = 1), 1 unit represents the Savings.

Given Savings = ₹200 ⇒ 1 unit = ₹200.

Ramesh's Income = 3 units = 3 × 200 = ₹600.

Suresh's Income = 4 units = 4 × 200 = ₹800.

∴ The correct answer is ₹600 and ₹800.

Alternate Method

Given:

Ratio of Income = 3 : 4

Ratio of Expenditure = 2 : 3

Savings of each = ₹200

Formula Used:

Income − Expenditure = Savings

Calculations:

Let the Income of Ramesh and Suresh be 3x and 4x respectively.

Let the Expenditure of Ramesh and Suresh be 2y and 3y respectively.

According to the question:

⇒ 3x − 2y = 200 ... (Equation 1)

⇒ 4x − 3y = 200 ... (Equation 2)

From (1) and (2), we have:

⇒ 3x − 2y = 4x − 3y

⇒ 3y − 2y = 4x − 3x

⇒ y = x

Substituting y = x in Equation 1:

⇒ 3x − 2x = 200

⇒ x = 200

Now, finding the Incomes:

⇒ Ramesh's Income = 3x = 3 × 200 = ₹600

⇒ Suresh's Income = 4x = 4 × 200 = ₹800

∴ The correct answer is ₹600 and ₹800.

Additional Information

Income-Expenditure-Savings Relation

The basic relationship is always Income = Expenditure + Savings. For two people, if savings are equal, the differences between their income and expenditure ratios must be made equal.

Ratio Balancing Method

If the difference between Income parts and Expenditure parts is not equal, multiply the ratios by the difference of the other ratio to balance them (e.g., multiply the first ratio by the difference of the second ratio).

Percentage Conversion

Income and expenditure problems can also be solved using Percentages where Income is considered as 100% and Savings % = 100% − Expenditure %.

Shortcut Trick

When the time traveled is constant, the ratio of distances covered equals the ratio of speeds.

Ratio of speeds = 32 : 96 = 1 : 3

Difference in distance ratio = 3 − 1 = 2 parts

Given 2 parts = 160 km ⇒ 1 part = 80 km

Total distance = 1 part + 3 parts = 4 parts = 4 × 80 = 320 km.

∴ The correct answer is 320 km.

Alternate Method

Given:

Speed of train from C = 32 km/hr

Speed of train from D = 96 km/hr

Formula Used:

Distance = Speed × Time

Station C Station D

Meeting Point

d km

(d + 160) km

32 km/hr

96 km/hr

Calculations:

⇒ Let the time taken for the trains to meet be t hours.

⇒ Distance covered by the first train = 32 × t = 32t km

⇒ Distance covered by the second train = 96 × t = 96t km

⇒ Difference in distance = 96t − 32t = 64t km

⇒ Given that the difference is 160 km ⇒ 64t = 160

⇒ t = 160 ÷ 64 = 2.5 hours

⇒ Total distance between C and D = 32t + 96t = 128t km

⇒ Total distance = 128 × 2.5 = 320 km

∴ The correct answer is 320 km.

Additional Information

Relative Speed (Opposite Direction)

When two objects move towards each other, their relative speed is the sum of their individual speeds: Relative Speed = S₁ + S₂.

Relative Speed (Same Direction)

When two objects move in the same direction, their relative speed is the difference of their individual speeds: Relative Speed = |S₁ − S₂|.

Time of Meeting

If two objects start at the same time towards each other from a total distance D, the time taken to meet is given by: Time = D ÷ (S₁ + S₂).

Given:

X and Y together can complete the work in 10 days

Y and Z together can complete the work in 12.5 days

Z and X together can complete the work in 50 days

Formula used:

Work done per day = 1 / Time taken

Let the work done by X, Y, and Z per day be x, y, and z respectively.

Calculations:

1. X and Y together can complete the work in 10 days, so: x + y = 1 / 10

2. Y and Z together can complete the work in 12.5 days, so: y + z = 1 / 12.5 = 0.08

3. Z and X together can complete the work in 50 days, so: z + x = 1 / 50 = 0.02

We now have the following system of equations:

1. x + y = 0.1

2. y + z = 0.08

3. z + x = 0.02

Adding all three equations:

(x + y) + (y + z) + (z + x) = 0.1 + 0.08 + 0.02

2x + 2y + 2z = 0.2

⇒ x + y + z = 0.1

The total work done by all three per day is 0.1, so the time taken by all three to complete the work together is:

Time = 1 / (x + y + z) = 1 / 0.1 = 10 days

∴ All three together can complete the work in 10 days.

Given:

We need to find the smallest perfect square divisible by both 4 and 3.

Formula used:

A perfect square is a number whose square root is an integer. To be divisible by both 4 and 3, the number must be divisible by the least common multiple (LCM) of 4 and 3.

Calculations:

The LCM of 4 and 3 is 12 (since 4 = 2² and 3 = 3, so the LCM is 2² × 3 = 12).

Now, we need the smallest perfect square divisible by 12.

For a number to be a perfect square, the exponents of all prime factors in its prime factorization must be even. The prime factorization of 12 is 2² × 3. Since the exponent of 3 is odd, we need to multiply by 3 to make the exponent of 3 even.

Thus, the smallest perfect square divisible by 12 is 12 × 3 = 36.

∴ The smallest perfect square divisible by both 4 and 3 is 36.

Given:

P and Q together can complete the work in 30 days.

P leaves the work after 20 days and Q completes the remaining work in 50 more days.

Formula used:

Work done by P and Q together = 1 / 30 (since they can complete the work in 30 days)

Work done by Q alone = (Remaining work) / 50 days

Calculations:

Let the total work be 1 unit.

Work done by P and Q together per day = 1 / 30

In 20 days, the work done by both = (1 / 30) × 20 = 20 / 30 = 2 / 3 units.

The remaining work = 1 - 2/3 = 1/3 units.

Q alone completes the remaining work in 50 days, so the work done by Q per day = (1/3) / 50 = 1 / 150 units per day.

Now, the rate of work done by P alone per day = (Work done by P and Q together) - (Work done by Q alone) = 1 / 30 - 1 / 150

⇒ P's rate of work = (5 - 1) / 150 = 4 / 150 = 2 / 75 units per day.

Therefore, the number of days P alone can complete the entire work = 1 / (2 / 75) = 75 / 2 = 37.5 days.

∴ P alone can complete the entire work in 37.5 days.

Given:

Ratio of marks of J and K = 15 ∶ 17

Marks of J = 300

Formula used:

Let the marks of K be x.

According to the ratio, 15/17 = 300/x

Calculations:

15/17 = 300/x

⇒ 15x = 17 × 300

⇒ 15x = 5100

⇒ x = 5100 / 15

⇒ x = 340

∴ The marks of K are 340.

Given:

Marked price (M.P.) = ₹3950

Selling price (S.P.) = ₹3160

Formula used:

Discount = Marked Price - Selling Price

Discount Percentage = (Discount / Marked Price) × 100

Calculations:

Discount = 3950 - 3160 = ₹790

Discount Percentage = (790 / 3950) × 100

⇒ Discount Percentage = 0.2 × 100

⇒ Discount Percentage = 20%

∴ The discount percentage offered on the book is 20%.

Given:

Average age of the family = 25 years

Number of family members = 4

Ages of three family members = 20, 22, and 28

Formula used:

Average age = Total age of family members / Number of family members

Calculations:

Let the age of the fourth family member be x.

The total age of the family = 20 + 22 + 28 + x

Average age = (20 + 22 + 28 + x) / 4 = 25

⇒ (70 + x) / 4 = 25

⇒ 70 + x = 25 × 4

⇒ 70 + x = 100

⇒ x = 100 - 70

⇒ x = 30

∴ The age of the fourth family member is 30 years.

Given:

Income = 9x

Expenditure = 7x

Formula used:

New Income = Income + (20/100) × Income

New Expenditure = Expenditure - (70/100) × Expenditure

Calculations:

New Income = 9x + (20/100) × 9x = 10.8x

New Expenditure = 7x - (70/100) × 7x = 2.1x

New Ratio = New Income : New Expenditure = 10.8x : 2.1x

⇒ New Ratio = ${108x}:{21x}$

⇒ New Ratio = 36 : 7

∴ The new respective ratio of income and expenditure is 36 : 7.

Given:

Principal (P) = ₹9000

Formula used:

Simple Interest (S.I.) = P × r × t / 100

Amount (A) = P × (1 + r/100)^t

Compound Interest (C.I.) = A - P

Calculations:

1. Simple Interest:

S.I. = 9000 × 20 × 2 / 100

⇒ S.I. = 9000 × 40 / 100

⇒ S.I. = 360000 / 100

⇒ S.I. = ₹3600

Statement I is incorrect: Simple Interest is ₹3600.

2. Compound Interest:

A = 9000 × (1 + 20/100)²

⇒ A = 9000 × (1.2)²

⇒ A = 9000 × 1.44

⇒ A = ₹12960

C.I. = A - P = 12960 - 9000

⇒ C.I. = ₹3960

Statement II is correct: Compound Interest is ₹3960.

∴ Only Statement II is correct.

Given:

55 is subtracted from 65% of a number, and the result is 400.

Formula used:

Let the number be x.

65% of x = 0.65x

0.65x - 55 = 400

Calculations:

0.65x - 55 = 400

⇒ 0.65x = 400 + 55

⇒ 0.65x = 455

⇒ x = 455 / 0.65

⇒ x = 700

∴ The value of the number is 700.

Given:

Radius (r) = 21 cm

Formula used:

Curved Surface Area (C.S.A.) of a hemisphere = 2πr²

Calculations:

C.S.A. = 2 × (22/7) × (21)²

⇒ C.S.A. = 2 × (22/7) × 441

⇒ C.S.A. = (44/7) × 441

⇒ C.S.A. = 44 × 63

⇒ C.S.A. = 2772 cm²

∴ The curved surface area of the hemisphere is 2772 cm².
