Given:

Sonu alone can make a table in 125 days.

Monu alone can make a table in 250 days.

Monu worked for 75 days.

Formula Used:

Work done by Monu in 75 days = (Monu's 1 day work) × 75

Remaining work = Total work - Work done by Monu

Time taken by Sonu to finish the remaining work = Remaining work / Sonu's 1 day work

Calculation:

Monu's 1 day work = 1/250

Work done by Monu in 75 days = 75 × 1/250

⇒ Work done by Monu in 75 days = 75/250

⇒ Work done by Monu in 75 days = 3/10

Remaining work = 1 - 3/10

⇒ Remaining work = 10/10 - 3/10

⇒ Remaining work = 7/10

Sonu's 1 day work = 1/125

Time taken by Sonu to finish the remaining work = (7/10) / (1/125)

⇒ Time taken by Sonu = (7/10) × 125

⇒ Time taken by Sonu = 875/10

⇒ Time taken by Sonu = 87.5 days

Sonu can finish the remaining work in 87.5 days.

Given:

The present ages of three people in proportions is 3:5:7.

Six years ago, the sum of their ages was 87 years.

Formula Used:

Let the present ages be 3x, 5x, and 7x.

Sum of their ages six years ago = (3x - 6) + (5x - 6) + (7x - 6)

Calculation:

Six years ago, the sum of their ages was 87.

(3x - 6) + (5x - 6) + (7x - 6) = 87

⇒ 3x + 5x + 7x - 18 = 87

⇒ 15x - 18 = 87

⇒ 15x = 87 + 18

⇒ 15x = 105

⇒ x = 105 / 15

⇒ x = 7

Present ages:

3x = 3 × 7 = 21 years

5x = 5 × 7 = 35 years

7x = 7 × 7 = 49 years

The present ages are 21 years, 35 years, and 49 years.

Given:

Radius of the sphere = 3.5 cm.

Formula Used:

Total surface area of a sphere = 4πr²

Calculation:

Radius (r) = 3.5 cm

Total surface area = 4 × π × (3.5)²

⇒ Total surface area = 4 × (22/7) × (3.5 × 3.5)

⇒ Total surface area = 4 × (22/7) × 12.25

⇒ Total surface area = 154 cm²

The total surface area of the sphere is approximately 154 cm².

Given:

443 - 226 ÷ 2 × 5

Formula Used:

Order of operations (PEMDAS/BODMAS): Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)

Calculation:

Step 1: Perform division first

226 ÷ 2 = 113

Step 2: Perform multiplication

113 × 5 = 565

Step 3: Perform subtraction

443 - 565

⇒ 443 - 565 = -122

The correct answer is option 4: -122.

Given:

Distance to destination = 300 km

Delay in departure = 60 minutes = 1 hour

Increased speed = Usual speed + 10 km/hr

Formula Used:

Time = Distance / Speed

Calculation:

Let the usual speed of the bus be x km/hr.

Time taken at usual speed = 300 / x

Time taken at increased speed (x + 10) = 300 / (x + 10)

Since the bus is 1 hour late:

300 / x - 300 / (x + 10) = 1

⇒ 300(x + 10) - 300x = x(x + 10)

⇒ 300x + 3000 - 300x = x² + 10x

⇒ 3000 = x² + 10x

⇒ x² + 10x - 3000 = 0

Solving the quadratic equation:

x = [-10 ± √ (10² - 4×1×(-3000))] / 2×1

⇒ x = [-10 ± √ (100 + 12000)] / 2

⇒ x = [-10 ± √ (12100)] / 2

⇒ x = [-10 ± 110] / 2

Taking the positive value:

⇒ x = (110 - 10) / 2

⇒ x = 100 / 2

⇒ x = 50 km/hr

The usual speed of the bus is 50 km/hr.

Given:

X1 can do the work in 90 days.

X2 can do the work in 45 days.

X3 can do the work in 67.5 days.

X2 left 13.5 days before the completion of the work.

Calculation:

 

Let 'x' be the time taken by all to complete the work,

3x + 6(x - 13.5) + 4x = 270

⇒ 3x + 6x - 81 + 4x = 270

⇒ 13x = 270 + 81

⇒ 13x = 351

⇒ x = 351/13 = 27 days.

The work was completed in 27 days.

Given:

Marked price of an article = Rs. 11800

Selling price of an article = Rs. 7788

Formula Used:

Discount Percentage = ((Marked Price - Selling Price) / Marked Price) × 100

Calculation:

Marked Price = Rs. 11800

Selling Price = Rs. 7788

Discount = Marked Price - Selling Price

⇒ Discount = 11800 - 7788

⇒ Discount = 4012

Discount Percentage = (Discount / Marked Price) × 100

⇒ Discount Percentage = (4012 / 11800) × 100

⇒ Discount Percentage ≈ 0.34 × 100

⇒ Discount Percentage ≈ 34%

The discount percentage is 34%.

Given:

Original price of the dress = Rs. 800

Reduced price of the dress = Rs. 720

Formula Used:

Percentage Decrease = (Decrease in Price / Original Price) × 100

Calculation:

Decrease in Price = Original Price - Reduced Price

⇒ Decrease in Price = 800 - 720

⇒ Decrease in Price = 80

Percentage Decrease = (80 / 800) × 100

⇒ Percentage Decrease = 0.1 × 100

⇒ Percentage Decrease = 10%

The percentage decrease is 10%.

Given:

Original average marks of 13 students = 130

Incorrect score entered for one student = 23

Correct score for that student = 32

Formula Used:

Correct Average = (Total Sum of Marks - Incorrect Score + Correct Score) / Number of Students

Calculation:

Total Sum of Marks = 130 × 13

Total Sum of Marks = 1690

Corrected Total Sum of Marks ⇒ 1690 - 23 + 32

Corrected Total Sum of Marks ⇒ 1699

Correct Average ⇒ 1699 / 13

Correct Average = 130.69

The correct average of their score is 130.69.

Given:

Initial loss = 10%

Profit in new scenario = 10%

Difference in selling price = Rs. 26

Reduction in cost price = 30%

Formula Used:

1. Selling Price (SP) = Cost Price (CP) × (1 ± Profit/Loss Percentage)
2. New Cost Price = Original Cost Price × (1 - Reduction Percentage)
3. Difference in Selling Price = Original SP - New SP

Calculation:

Let the original cost price be CP.

Initial Selling Price (SP) = CP × (1 - 0.10)

⇒ Initial SP = 0.9CP

New Cost Price = CP × (1 - 0.30)

⇒ New CP = 0.7CP

New Selling Price = New CP × (1 + 0.10)

⇒ New SP = 0.7CP × 1.10

⇒ New SP = 0.77CP

Difference in Selling Price = Initial SP - New SP

⇒ 0.9CP - 0.77CP = 26

⇒ 0.13CP = 26

⇒ CP = 26 / 0.13

⇒ CP = 200

The cost price of the article is Rs. 200.

Shortcut Trick

Given:

Number to be divided = 3529

Divisor = 10

Formula Used:

Shortcut Trick

Convert each ratio into a decimal value to compare easily.

Prithvi: 10 ÷ 13 ≈ 0.769

Celine: 7 ÷ 9 ≈ 0.777

Vikram: 5 ÷ 7 ≈ 0.714

Comparing the values: 0.777 > 0.769 > 0.714.

∴ The correct answer is Celine.

Alternate Method

Given:

Ratio for Prithvi = 10 ∶ 13

Ratio for Celine = 7 ∶ 9

Ratio for Vikram = 5 ∶ 7

Calculations:

To compare fractions, we can find a common denominator or use cross-multiplication.

Comparing Prithvi (10/13) and Celine (7/9):

⇒ 10 × 9 = 90 and 13 × 7 = 91

⇒ Since 91 > 90, then 7/9 > 10/13.

Comparing Celine (7/9) and Vikram (5/7):

⇒ 7 × 7 = 49 and 9 × 5 = 45

⇒ Since 49 > 45, then 7/9 > 5/7.

⇒ Therefore, 7/9 is the greatest ratio.

∴ The correct answer is Celine.

Additional Information

Ratio Comparison

To compare two ratios a:b and c:d, compare the fractions a/b and c/d by cross-multiplying (ad vs bc).

Decimal Conversion

If two ratios are equal (a/b = c/d), they are said to be in proportion.

Given:

Average weight of a class of 22 students = 42 kg

Weights of 2 new students = 33 kg and 39 kg

Formula Used:

New average weight = (Total weight of all students) / (Total number of students)

Calculation:

Total weight of 22 students = 22 × 42

Total weight of 22 students = 924 kg

Total weight after adding 2 new students = 924 + 33 + 39

Total weight after adding 2 new students = 996 kg

Total number of students = 22 + 2

Total number of students = 24

New average weight = 996 / 24

New average weight = 41.5 kg

The new average weight of 24 students is 41.5 kg.

Shortcut Trick

When the Total Expenditure is constant (₹1 in both cases), the Quantity is inversely proportional to the Price.

Price Ratio (CP : SP) = 100 : (100 − 30) = 100 : 70 = 10 : 7

Quantity Ratio (CP : SP) = 7 : 10

Given: CP quantity = 7 units → 35 mangoes

⇒ 1 unit = 5 mangoes

⇒ SP quantity = 10 units = 10 × 5 = 50 mangoes

∴ The correct answer is 50 mangoes.

Alternate Method

Given:

Number of mangoes bought for ₹1 = 35

Loss percentage = 30%

Formula: Selling Price (SP) = CP × (100 − Loss%)/100

⇒ CP of 35 mangoes = ₹1

⇒ CP of 1 mango = ₹1/35

⇒ SP of 1 mango = (1/35) × (100 − 30)/100

⇒ SP of 1 mango = (1/35) × (70/100)

⇒ SP of 1 mango = (1/35) × (7/10)

⇒ SP of 1 mango = 1/(5 × 10) = ₹1/50

⇒ Since SP of 1 mango is ₹1/50, the number of mangoes sold for ₹1 = 50

∴ The correct answer is 50 mangoes.

Additional Information

Price-Quantity Relationship

When expenditure is constant, Price per unit × Quantity = Constant. Thus, Price is inversely proportional to Quantity (P₁/P₂ = Q₂/Q₁).

Profit and Loss Percentage

Profit % = (Profit/CP) × 100 and Loss % = (Loss/CP) × 100. All profit or loss percentages are always calculated on the Cost Price unless stated otherwise.

Direct SP Calculation

To find the selling price for a desired profit, use SP = CP × (100 + Profit%)/100. For loss, use SP = CP × (100 − Loss%)/100.

Shortcut Trick

SI for 1 year = 12800 ÷ 2 = ₹6400.

Difference (D) between CI and SI for 2 years = 14400 − 12800 = ₹1600.

Direct formula for Principal (P): P = (SI for 1st year)² ÷ D

P = (6400 × 6400) ÷ 1600 = 4 × 6400 = ₹25600.

∴ The correct answer is ₹25600.

Alternate Method

Given:

Simple Interest (SI) for 2 years = ₹12800

Compound Interest (CI) for 2 years = ₹14400

Time (T) = 2 years

Calculations:

⇒ SI for 1 year = 12800 ÷ 2 = ₹6400

⇒ Difference = CI − SI = 14400 − 12800 = ₹1600

⇒ This difference is the interest on the 1st year's SI.

⇒ Rate (R) = (Difference ÷ SI for 1 year) × 100

⇒ R = (1600 ÷ 6400) × 100 = 25%

⇒ Principal (P) = (SI for 1 year × 100) ÷ R

⇒ P = (6400 × 100) ÷ 25

⇒ P = 6400 × 4 = ₹25600

∴ The correct answer is ₹25600.

Additional Information

Calculation:

Step 1: Division and Multiplication

2016 ÷ 4 = 504

32 × 6 = 192

26 × 3 = 78

Step 2: Addition and Subtraction

⇒ 504 + 192 - 78

⇒ 696 - 78

⇒ 618

The value of the expression is 618.

Shortcut Trick

Marked Price (MP) = Selling Price + Discount = 220 + 20 = 240.

Ratio of Cost Price (CP) to MP = 100 : 120 = 5 : 6.

Since 6 units = ₹240, then 1 unit = ₹40.

Therefore, CP = 5 units = 5 × 40 = ₹200.

Profit = SP − CP = 220 − 200 = ₹20.

Profit % = (20 / 200) × 100 = 10%.

∴ The correct answer is 10%.

Alternate Method

Given: Selling Price (SP) = ₹220, Discount = ₹20, Marked Price (MP) = 120% of CP.

Formula Used: MP = SP + Discount; Profit % = [(SP − CP) ÷ CP] × 100.

⇒ MP = ₹220 + ₹20 = ₹240

⇒ 120% of CP = ₹240

⇒ CP = (240 × 100) ÷ 120

⇒ CP = 2 × 100 = ₹200

⇒ Profit = SP − CP = 220 − 200 = ₹20

⇒ Profit % = (20 ÷ 200) × 100

⇒ Profit % = 10%

∴ The correct answer is 10%.

Additional Information

Given:

Expression: (48 - (20 - 8)) ÷ (4 × 3)

Formula Used:

Order of Operations (PEMDAS/BODMAS)

Calculation:

Simplify inside the parentheses first:

48 - (20 - 8)

⇒ 48 - 12

⇒ 36

Next, perform the multiplication:

4 × 3

⇒ 12

Now, divide the results:

36 ÷ 12

⇒ 3

The value of the expression is 3.

Given:

A certain sum becomes 7 times of itself in 10 years at a rate of simple interest.

Formula Used:

Simple Interest (SI) = Principal (P) × Rate (R) × Time (T) / 100

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

Calculation:

Let the principal be P.

In 10 years, the amount A = 7P.

We know A = P + SI.

⇒ 7P = P + SI

⇒ SI = 7P - P = 6P

Using the simple interest formula:

SI = P × R × T / 100

⇒ 6P = P × R × 10 / 100

⇒ 6P = P × R × 0.1

⇒ 6 = R × 0.1

⇒ R = 6 / 0.1

⇒ R = 60

Now, we need to find out how many times the sum will become in 20 years.

Using the simple interest formula again:

SI in 20 years = P × R × 20 / 100

⇒ SI = P × 60 × 20 / 100

⇒ SI = 12P

Total amount in 20 years = Principal + Simple Interest

⇒ A = P + 12P

⇒ A = 13P

In 20 years, the sum will become 13 times of itself.

Shortcut Trick

32% + 15 = 57% - 10

⇒ 15 + 10 = 57% - 32%

⇒ 25 = 25%

⇒ 1% = 1

So, Passing marks = 32% + 15 = 32 + 15 = 47

∴ The correct answer is option (4). 

Alternate Method

Given:

Vikram's score at 32% = Passing marks - 15

Vikram's score at 57% = Passing marks + 10

Formula Used:

Passing marks (P) = Total marks (T) × Passing percentage

Calculation:

Let the total marks be T.

At 32%, Vikram's score = 0.32T

At 57%, Vikram's score = 0.57T

According to the problem:

0.32T = P - 15

0.57T = P + 10

Solving the equations:

0.57T = 0.32T + 25

⇒ 0.57T - 0.32T = 25

⇒ 0.25T = 25

⇒ T = 25 / 0.25

⇒ T = 100

Now, finding the passing marks:

P = 0.32T + 15

P = 0.32 × 100 + 15

P = 32 + 15

P = 47

The passing marks for the exam are 47.
