Formula:

profit % = $sp - cp \over cp$ × 100

Given:

sp = 53760

profit = 12%

Calculation:

12 = $53760 - cp\over cp$ × 100

12cp = 5376000 - 100cp

112cp = 5376000

cp = 48000

Hence, 48000 is the correct answer.

Given equation : 12 ÷ 6 + 24 × 3 - 8 = 72

By going with the options, we check the values

option 1) × and -

12 ÷ 6 + 24 - 3 × 8

= 2 + 24 - 3 × 8

= 2 + 24 - 24

= 2

option 2) - and +

12 ÷ 6 - 24 × 3 + 8

= 2 - 24 × 3 + 8

= 2 - 72 + 8

= - 62

option 3) ÷ and ×

12 × 6 + 24 ÷ 3 - 8

= 12 × 6 + 8 - 8

= 72 + 8 - 8

= 72

option 4) + and ÷ 

12 + 6 ÷ 24 × 3 - 8

= 12 + 0.25 × 3 - 8

= 12 + 0.75 - 8

= 4.75

Hence, the answer is ÷ and ×

In option 1, there are 6 small circles so the hexagon area is divided into 6 parts,

In option 2, there are 4 small diamond so the rectangle area is divided into 4 parts,

In option 3, there are 5 small circles so the pentagon area is divided into 5 parts,

In option 4, there are 3 small squares so the triangle area should be divided into 3 parts, but here it is divided into 4 parts.

Hence, the figure in option 4 is the correct answer.

The pattern followed here is:

The number of circles is increased by 1 in every step and shifted upward and downward in alternate steps.

The number of sides of the figure reduces by 1 and shifts downward and upward in alternate step. 

Thus, the answer figure should contain a triangle and four circles above the triangle.

Hence, the figure in option 2 is the correct answer.

When the question figure is merged with the figure in option 1, the complete pattern can be seen.

Hence, the figure in option (1) is the correct answer.

Given: 

The length of the minute hand = 10.5 cm

Total time = 10 minutes 

Formula used:

Length of an arc = 2πr × θ/360

Area of an arc = πr² × θ/360

Calculation:

If we divide 360° by 12 numberings of the clock, then we will get that 5 minutes on the clock is equal to the 30° of angular space.

The angle of 10 minutes = 30° × 2

⇒ The angle of sector = 60°

Area of an arc = π × (10.5)² × 60/360 

⇒ π × (10.5)² × 1/6 = (22/7) × (10.5)² × 1/6

⇒ 57.75 cm

∴ The area swept in 10 minutes is 57.75 cm²

Given:

The salary of typist increased = 20%

The change in salary of the typist is decreased = 5%

After Increment of 20% & decrement of 5% his present salary = 17100

Calculation:

Let the original salary be 'x'

After 20% of increment of salary of typist = x + 20% of x

⇒ x(1 + 20%) = x(1 + 20/100)

⇒ x(100 + 20)/100 = 120x/100

⇒ 120x/100 = 6x/5

After decremnt of 5% salalry of typist = 6x/5 - 5% of 6x/5

⇒ (6x/5)(1 - 5%) = (6x/5)(1 - 5/100)

⇒ (6x/5)(100 - 5)/100 = (6x/5)(95/100)

⇒ 57/50x

Salary of typist after increment and decrement = 57x/50

57x/50 = 17100

⇒ x = 17100 × 50/51

⇒ x = 15000

∴ The salary of typist initially is Rs. 15000

Alternate Method

x × (120/100) × (95/100) = 17100

⇒ x = 17100 × (100/120) × (100/95)

⇒ x = 15000

Given:

Radius of a cylinder = 1.4 m 

Height of a cylinder = 5 m

The earth raise platform  = 10 × 8 × h

Concept Used:

Volume of cylinder = πr²h where r is the radius of the base

And h is the height of the cylinder

Volume of cuboid = Length × Breadth × Height

Calculations:

Volume of a cylinder = volume of cuboid 

⇒ (22/7) × 1.4 × 1.4 × 5 = 10 × 8 × h

⇒ (22/7) × 1.4 × 0.7 = 8 × h

⇒ h = (22/7) × 1.4 × 0.7/8

⇒ h = 0.385 m

⇒ h = 38.5 cm

∴ The height of the platform is 38.5 cm

Key Points

1m = 100 cm

Given:

The selling price of an article = Rs. 796.875

Two successive discounts = 15% and 25% respectively

The cost price of the article = Rs.1,000

Formula used:

Gain = selling price - cost price

Gain% = (gain/cost price) × 100

Calculations:

Let the marked price be x

After allowing First discount 15% = x - 15%x

⇒ x(1 - 15/100) = x(100 - 15)/100

⇒ x × 85/100 = 17x/20

After allowing Second discount 25% = 17x/20 - (17x/20) 25%

⇒(17x/20)(1 - 25/100) = (17x/20)(100 - 25)/100

⇒ (17x/20) × 75/100 = (17x/20) × 3/4

⇒ 51x/80 

51x/80 = 796.875

⇒ x = 796.875 × 80/51

⇒ x =  1250

If he sold 1250,  gain = 1250 - 1000

⇒ 250

Gain percentage = (250/1000) × 100

⇒ 25%

∴ The percentage gain if sold at marked price is 25%

Alternate Method

85% of 75% of marked price = 796.875 

Marked  price = 796.875 × 100 × 100/(85 × 75)

⇒ 1250

Gain% = (1250 - 1000)/1000 × 100

⇒ 25%

Given:

Total number of questions in a competative examination = 200

Savita answerd questions correctly = 70% of 150questions

Calculations:

60% of 200 questions = (60/100) × 200 = 120

70% of 150 questions = (70/100) × 150 = 105

Remaining questions = 200 - 150 = 50 questions

To get 120 marks she should have to answer correctly

⇒ 120 - 105 = 15

Percentage of question to answer = (15/50) × 100 = 30

∴ Savita must answer 30 questions to secure 60% from the remaining questions

Shortcut Trick

Efficiency Ratio: 10 Men × 10 = 12 Women × 10 ⇒ 5 Men = 6 Women.

Total Work = 10 Men × 10 days = 100 Man-days.

Group Efficiency = 8 Men + 6 Women = 8 Men + 5 Men = 13 Men.

Required Days = 100 ÷ 13 = 7 9/13 days.

∴ The correct answer is 7 9/13 days.

Alternate Method

Given: 10 Men (M) in 10 days; 12 Women (W) in 10 days.

Formula Used: Total Work = M × D × E (Efficiency); Days = Total Work ÷ Combined Efficiency

⇒ Efficiency of 1 Man = 60 ÷ 10 = 6 units/day

⇒ Efficiency of 1 Woman = 60 ÷ 12 = 5 units/day

⇒ Total Work = 10 × 10 × 6 = 600 units

⇒ Efficiency of (8 Men + 6 Women) = (8 × 6) + (6 × 5) = 48 + 30 = 78 units/day

⇒ Required Days = 600 ÷ 78 = 100 ÷ 13 = 7 9/13 days

∴ The correct answer is 7 9/13 days.

Additional Information

M₁D₁H₁ Formula

The relation between men, days, and work is (M₁ × D₁) / W₁ = (M₂ × D₂) / W₂.

Shortcut TrickFrom option 1 

Number x = 4 

According to question 

⇒ 4 + 17 = 21

(1/21) × 84 = 4

∴ Correct answer is 4.

Given:

A positive number which when increased by 17 is equal to 84 times the reciprocal of the number

calculation:

Let the positive number be x 

Reciprocal of a positive number = 1/x

x + 17 = 84 × 1/x

⇒ x (x + 17) = 84

⇒ x² + 17x = 84

⇒ x2 + 17x - 84 = 0

⇒ x² + 21x - 4x - 84 = 0

⇒ x(x + 21) - 4( x + 21) = 0

⇒ (x + 4)(x - 21) = 0

⇒ x = 4, -21

The value of x is positive, So x = 4

∴ The required value is 4

Given:

A person invested one-third of his money at the rate of interest = $3\frac{1}{2}$

One-fourth of his money at the rate of interest =  $7\frac{1}{2}$

Remaining money at the rate of interest = 8%

Simple interest yearly = 1479

Formula used:

Simple interest = PTR/100

Calculations:

Let the sum of money be x

1/3rd  of amount = x/3

1/4 th of amount = x/4

Reamining amount = x - x/3 - x/4

⇒ (12x - 4x - 3x)/12 = 5x/12

Simple interst = [(x/3) × $3\frac{1}{2}$ + (x/4)( $7\frac{1}{2}$) + (5x/12) × 8]/100

⇒ [(x/3) × (7/2) + (x/4)(15/2) + (5x/12) × 8]/100 = [(7x/6 + 15x/8 + 40x/2]/100

⇒ [(28x + 45x + 80x)/24]/100 = 153x/2400

Accordingly,

1479 = 153x/2400

⇒ x = 1479 × 2400/153

⇒ x = 23200

∴ The sum of amount is 23200

Given:

Mrs. Sharma bought fabric for her elder daughter = 7.35 m

Mrs. Sharma bought fabric for her younger daughter = 6.75 m

Mrs. Sharma bought fabric for her husband  = 8.57 m

Mrs. Sharma bought fabric for herself = 7.83 m

Concept Used:

Total fabric bought is the sum of all members fabrics

Formula used:

Total  = a + b + c + d

Calculations:

Total fabric brought by Mrs. Sharma

⇒ 7.35 + 6.75 + 8.57 + 7.83 =  30.5

∴ The total fabric brought by Mrs. Sharma is 30.5

Given:

Total spendings = 11000

The cost price of cupboards = 1000

The cost price of Chair = 300

Calculations:

Let the number of cupboards be 'x'

Let the number of chairs be 'y'

When the maximum possible number of chairs x < y 

1000x + 300y = 11000

Let cupboards = 1

Then 11000 = 1 × 1000 + 300y

Number of chairs not integer. 

Let cupboards = 2 then

11000 = 2 × 1000 + 300y

⇒ Number of chairs (y) = 30.

So, maximum number of chair can be 30

So, 2 : 30 = 1 : 15

∴ The required answer is 1 ∶ 15

Shortcut Trick

Total Revenue Units (in terms of fixed price P) = (15 × 1) + (10 × 0.9) + (20 × 0.9 × 0.75) = 15 + 9 + 13.5 = 37.5 units.

Total Revenue ₹1875 ⇒ Fixed price per kg (P) = 1875 ÷ 37.5 = ₹50.

Total Cost Price (CP) of 50 kg = Total Revenue ÷ 120% = 1875 ÷ 1.2 = ₹1562.5.

Revenue if all 50 kg sold at fixed price = 50 × 50 = ₹2500.

Profit % = (2500 − 1562.5) ÷ 1562.5 × 100 = 937.5 ÷ 1562.5 × 100 = 60%.

∴ The correct answer is 60%.

Alternate Method

Given:

Total sugar = 50 kg | Kept for use = 5 kg | Sugar for sale = 45 kg

Total SP = ₹1875 | Profit = 20%

Formula Used:

SP = CP × (1 + Profit/100) | Discounted Price = Marked Price × (1 − Discount/100)

15 kg @ P 10 kg @ 0.9P 20 kg @ 0.675P

Total Revenue = ₹1,875

Total CP = ₹1,562.5

Fixed Price P = ₹50/kg

Calculations:

⇒ Total CP of 50 kg sugar = 1875 ÷ 1.2 = ₹1562.5

⇒ Let Fixed Price be P. Total kg for sale = 50 − 5 = 45 kg

⇒ SP₁ (15 kg) = 15 × P

⇒ SP₂ (10 kg) = 10 × (0.9P) = 9P

⇒ SP₃ (Remaining 20 kg) = 20 × (0.9P × 0.75) = 20 × 0.675P = 13.5P

⇒ Total SP = 15P + 9P + 13.5P = 37.5P

⇒ 37.5P = 1875

⇒ P = 1875 ÷ 37.5 = ₹50 per kg

⇒ New SP for 50 kg = 50 × 50 = ₹2500

⇒ Profit = New SP − Total CP = 2500 − 1562.5 = ₹937.5

⇒ Profit % = (937.5 ÷ 1562.5) × 100

⇒ Profit % = 0.6 × 100 = 60%

∴ The correct answer is 60%.

Additional Information

Successive Discounts

If two successive discounts of a% and b% are given on an article, the single equivalent discount is (a + b − ab/100)%.

Profit and Loss on Variable Quantities

Profit % = [(Total Revenue − Total Cost) ÷ Total Cost] × 100. Always ensure the cost price is calculated for the same total quantity as the target selling quantity.

Marked Price Relationship

CP × (100 + Profit%) = MP × (100 − Discount%). This is used to find the ratio of CP to MP directly.

Given:

The length of the area to be paved = 4.83 m

The breadth of the area to be paved = 5.67 m

Formula used:

Area of the space that can be paved = Length × breadth

1 m = 100 cm

Calculations:

Area of the floor = 4.83 × 100 × 5.67 × 100

⇒ 273861 cm²

If the length of the maximum tile is x then the area of 1 tile should be x²

⇒ The area of the floor must be divisible by x²

Now from the given options only 21² i.e. 441 can divide 273861 completely and give whole number as remainder

273861 ÷ 21² = 621

∴ The side of the largest possible square tile is 21 cm.

Given:

Total number of students in a class = 48

The average weight of 32 boys = 50.25kg

The average weight of girls = 45.15kg

Concept used:

Total number of class = number of boys + number of girls

Formula required:

Average = sum of Ages / number of students

Calculations:

Number of girls = 48 - 32 = 16

Total weight of boys = 32 × 50.25 = 1608 

Total weight of girls = 16 × 45.15 = 722.4

Sum of the weight = 1608 + 722.4 = 2330.4

Average weight of 48 students = 2330.4 ÷ 48 =  48.55

∴ The average weight of 48 students is 48.55 kg

Given:

Sum = 2200

Rate of interest = 12%

Number of years = 2 years compounded half yearly

Concept:

In compound interest half yearly means the rate of interest is get halved

Formula used:

Amount = P[(1 + {(R/2) × 1/100})²ⁿ]

Calculations:

Amount = 2200[(1 + {(12/2) × 1/100})^{2 × 2}]

⇒ Amount = 2200 (1 + 6/100)⁴

⇒ Amount = 2200 × 106 × 106 × 106 × 106/(100 × 100 × 100 × 100)

⇒ Amount = 2777.449 ≈ 2777.45

∴ The amount after 2 years is Rs. 2777.45

Given:

Total time car runs = 11 hours

Formula used:

Time = Distance/speed

Calculations:

Let the speed of the car initially be x

For the first 100 km car runs with speed = x km/hr

After 100 km car increases speed by 15 km/hr = x + 15

Remaining distance = 280 km 

Total time  = 100/x + 280/(x + 15)

⇒ 11 = [(x + 15)100 + 280 × x]/[x(x + 15)]

⇒ 11 = (100x + 1500 + 280x )/(x² + 15x)

⇒ 11(x² + 15x) = 380x + 1500

⇒ 11x² + 165x = 380x + 1500

⇒ 11x2 + 165x - 380x - 1500 = 0

⇒ 11x2 - 215x  - 1500 = 0

⇒ 11x² - 275x + 60x - 1500 = 0

⇒ 11x(x - 25) + 60(x - 25) = 0

⇒ (11x + 60)(x - 25) = 0

So, x = - 60/11 or x = 25

Speed can't be negative so, x = 25

Initially speed was 25 km/h

Required time to cover the first 100 km is 100/25 = 4 hours.

∴ It takes 4 hours to cover the first 100 km.
