Given:

Internal radius = 14 m 

The depth =  10 m

Formula Used:

Area of wet surface = Curved Surface area + area of the base

Calculations:

According to the formula,

⇒ Area of curved surface area = (2\pi r h = 2\times \frac{22}{7} \times 14 \times 10 ) = 880 m²

⇒ Area of the base of cylinder = (\pi r^2 = \frac{22}{7} \times 14 \times 14) = 616 m²

⇒ Area of wet surface = Curved Surface area + area of the base = 880 + 616 = 1496 m²

⇒ Hence, The area of wet surface is 1496 m²

Given:

PQ = PR

S is a point on PQ such that PS = RS = QR.

Concept used:

The sum of the angles of a triangle is 180°.

If two sides of a triangle are equal, then the angles opposite those sides are also equal.

Calculation:

Let ∠QPR = x.

In ΔPSR,

⇒ PS = SR

⇒ ∠SPR = ∠SRP

⇒ Therefore, ∠SRP = x

Sum of the angles of a triangle = 180°

⇒ ∠PSR + x + x = 180°

⇒ ∠PSR = 180° - 2x

∠PSR + ∠RSQ = 180° (Linear pair)

⇒ ∠RSQ = 180° - ∠PSR

⇒ ∠RSQ = 180° - (180° - 2x) = 2x

Similarly, in ΔSQR,

⇒ QR = RS

⇒ ∠RSQ = ∠SQR

⇒ ∠SQR = 2x

Therefore, ∠PQR = ∠SQR = 2x

In ΔPQR, PR = PQ

⇒ ∠PQR = ∠PRQ

⇒ 2x = (180° - 4x + x)

⇒ 2x = 180° - 3x

⇒ 5x = 180°

⇒ x = 36°

∴ The measure of ∠QPR is 36°.

Given:

Radius = 3cm

Vertical height = 7cm

Formula Used:

The volume of ice cream = Volume of cone + Volume of the hemisphere

Calculations:

According to the formula,

The volume of ice cream

⇒  The volume of cone + Volume of the hemisphere

⇒ (1\over3)πr²h + (2\over3 )πr³

⇒ (1\over 3)πr²(h + 2r)

⇒ (1\over 3) × (22\over 7) × 3 × 3 × (7 + 2 × 3)

⇒ 2574/21 

∴ The volume of ice cream is 2574/21 cm³

Given:

One boy(A) and one girl(B) together can complete a piece of work in 12 days

A boy(A) alone can complete the work in 15 days

Formula Used:

Total Work = Efficiency x Days taken

Calculations:

Total Work = LCM of days taken by A and B together and Days taken by A alone = LCM of 12 and 15 = 60

Efficiency of A and B  = Total work / Days taken = 60 / 12 = 5 unit work in one day

Efficiency of A =  Total work / Days taken = 60 / 15 = 4 unit work in one day

Efficiency of B = Efficiency of A and B - Efficiency of A = 5 - 4 = 1 uint in one day

Total days were taken by B to complete the work = Total work / Efficiency = 60 / 1 = 60 days

∴ The days taken by the one girl (B) is 60 days

Given:

In the first lap

Distance covered = 500m

Time taken = 625 sec

In the second lap

Distance covered = 500m

Time taken = 375 sec

Formula Used:

Speed = Distance / Time

Average Speed = 2 × Speed1 × Speed2 / (Speed1 + Speed2) 

Calculations:

⇒ Speed1 = Distance / Time = 500 / 625 = 4 / 5 m/s

⇒ Speed2 = Distance / Time = 500 / 375 = 4 / 3 m/s

⇒ Average Speed = 2 x Speed1 x Speed2 / (Speed1 +Speed2) = (\frac{2× \frac{4}{5}×\frac{4}{3}}{\frac{4}{5}+\frac{4}{3}} = \frac{32}{32} = 1)

⇒ Hence, The average speed of the cyclist is 1 m/s

Given:

20 Multiples of 9

Formula Used:

Sum of the numbers= n(n+1) / 2

Average = Sum of the numbers / Total numbers

Calculations:

⇒ The first 20 multiples of 9 are,

⇒ 9, 18, 2 7, 36, .............. 171, 180

⇒ 9( 1, 2, 3, ...... 19 , 20)

⇒ so, n = 20

⇒ Sum of the numbers = 9 x 20 x 21 / 2 = 9 x 10 x 21 = 1890

⇒ Average = Sum of the numbers / Total numbers = 1890 / 20 = 94.5

⇒ Hence, The average of the first 20 multiples of 9 is 94.5

Given:

Concept Used:

The simple calculations used

Calculations:

⇒ (\rm \frac{1}{x}+\frac{1}{y}+\frac{1}{z}=1)

therefore,

⇒​ (\rm \frac{1}{x}+\frac{1}{y}=1 - \frac{1}{z}= \frac{z-1}{z} )

⇒​ (\rm \frac{1}{x}+\frac{1}{z}=1 - \frac{1}{y}= \frac{y-1}{y} )

⇒​ (\rm \frac{1}{y}+\frac{1}{z}=1 - \frac{1}{x}= \frac{x-1}{x} )

Putting these values in the above equations 

⇒​ (\rm \left(\frac{1}{z-1}\right)\left(\frac{1}{x}+\frac{1}{y}\right)+ \left(\frac{1}{y-1}\right)\left(\frac{1}{x}+\frac{1}{z}\right)+ \left(\frac{1}{x-1}\right)\left(\frac{1}{y}+\frac{1}{z}\right) )

⇒​ (\rm \left(\frac{1}{z-1}\right)\Big(\frac{z-1}{z}\Big)+ \left(\frac{1}{y-1}\right)\left(\frac{y-1}{y}\right)+ \left(\frac{1}{x-1}\right)\left(\frac{x-1}{x}\right) )

⇒​ (\rm \frac{1}{z}+\frac{1}{y}+\frac{1}{x}=1 )

⇒​ Hence, The value of the above equations is 1

Given:

The LCM of the two number

Concept Used:

LCM is the least common factor of two of more than two number

Calculations:

⇒ LCM of 3 and 5 is

⇒ 3 can be written as = 1 x 3

⇒ 5 can be written as = 1 x 5

As there is no common factor, so we have to multiply the factors

⇒ LCM of 3 and 5 = 3 x 5 = 15

Similarly,

⇒ LCM of 8 and 7 is

⇒ 8 can be written as = 1 x 8

⇒ 7 can be written as = 1 x 7

As there is no common factor, so we have to multiply the factors

⇒ LCM of 8 and 7 = 8 x 7 = 56

⇒ Hence the LCM of 8 and 7 is 56 so statement 2 is incorrect

Given:

Shortcut Trick Formula Used: 

(a + b) (a - b) = a² - b²

a^x × a^y = a^x+y 

Calculation:

(1 + y) (1 + y2)(1 + y4)(1 + y8)(1 − y)

⇒ (1 − y)(1 + y) (1 + y2)(1 + y4)(1 + y8)

⇒ (1 - y²)(1 + y2)(1 + y4)(1 + y8)

⇒ (1 - y⁴)(1 + y4)(1 + y8)

⇒ (1 - y⁸)(1 + y8)

⇒ 1 - y16

∴ The value is 1 - y16

Given:

(2.\overline{13}÷ 3.\overline{12})

Calculation:

Let x = (2.\overline{13})

Multiplying both sides by 100,

⇒ 100x = 213.13

Subtracting the first part from this, we get

⇒ 100x – x = 213.13 – 2.13

⇒ 99x = 211

⇒ x = (\frac{211}{99})

Let y = (3.\overline{12})

Multiplying both sides by 100,

⇒ 100y = 312.12

Subtracting the first part from this, we get

⇒ 100y – y = 312.12 – 3.12

⇒ 99y = 309

⇒ y = (\frac{309}{99})

⇒ Now, x ÷ y = (\frac{\frac{211}{99}}{\frac{309}{99}})= (\frac{211\times 99}{99\times 309})

⇒ x ÷ y = (\frac{211}{309})

∴ The required value of (2.\overline{13}÷ 3.\overline{12}) is (\frac{211}{309}).

Shortcut TrickIn numerator, subtract the non-recurring digit from the whole number.

In the denominator, no. of recurring digits = no. of 9's

⇒ (2.\overline{13}) = (213-2)/99 and (3.\overline{12}) = (312 - 3)/99

⇒  (2.\overline{13}÷ 3.\overline{12}) = {211/99} ÷ {309/99}

⇒ 211/309

Total CP = 5000 + 250 = ₹5,250

Loss = CP − SP = 5250 − 5075 = ₹175

Loss % = (175 ÷ 5250) × 100 = (1 ÷ 30) × 100 = 3.33%

∴ The correct answer is Loss of 3.33%.

Alternate Method

Given:

Purchase Price of bicycle = ₹5,000

Transportation Cost = ₹250

Selling Price (SP) = ₹5,075

Formula Used:

Total Cost Price (CP) = Purchase Price + Overhead Expenses

Loss = Total CP − Selling Price (when CP > SP)

Loss Percentage = (Loss ÷ Total CP) × 100

Calculations:

⇒ Total CP = 5,000 + 250 = ₹5,250

⇒ Loss = 5,250 − 5,075 = ₹175

⇒ Loss % = (175 ÷ 5,250) × 100

⇒ Loss % = (1 ÷ 30) × 100

⇒ Loss % = 3.333...

∴ The correct answer is Loss of 3.33%.

Additional Information

Overhead Expenses

Additional costs like transportation, repairs, or labor are always added to the initial Cost Price to determine the Effective Cost Price.

Profit and Loss Calculation

Profit or Loss percentage is always calculated based on the Total Cost Price unless specified otherwise.

Comparison Rules

If SP > CP, it results in Profit. If CP > SP, it results in Loss. If SP = CP, there is No Profit No Loss.

Given:

Money after 2 years = Rs. 34560

Money after 3 years = 41472

Formula Used:

Amount = P x (1 + R/100)^T

Calculations:

Let the Principle amount be Rs. 34560

After the 1 year, the amount received on compounded yearly = Rs. 41472

According to the formula,

Amount = P x (1 + R/100)^T

⇒ 41472 = 34560 x (1 + R/100)¹

41472 / 34560 = (100 + R) / 100

⇒ 1.2 x 100 = 100 + R

⇒ 100 + R = 120

⇒ R = 120 - 100

⇒ R = 20%

∴ The Value of the Rate of interest is 20%

Shortcut Trick

Ratio of Marked Price (MP) to Cost Price (CP) is given by (100 + Gain%) : (100 − Discount%).

MP : CP = (100 + 10) : (100 − 12) = 110 : 88.

Simplify the ratio: 110 : 88 = 5 : 4.

Given CP = 4 units = ₹5,800. Therefore, 1 unit = 5,800 ÷ 4 = ₹1,450.

MP = 5 units = 5 × 1,450 = ₹7,250.

∴ The correct answer is ₹7,250.

Alternate Method

Given: CP = ₹5,800, Gain% = 10%, Discount% = 12%.

Formulas: SP = CP × (100 + Gain%) ÷ 100 | MP = (SP × 100) ÷ (100 − Discount%)

⇒ Selling Price (SP) = 5,800 × (110 ÷ 100) = 5,800 × 1.1 = ₹6,380.

⇒ Marked Price (MP) = (6,380 × 100) ÷ (100 − 12) = 638,000 ÷ 88.

⇒ MP = ₹7,250.

∴ The correct answer is ₹7,250.

Additional Information

Relation between CP and MP

The direct formula CP ÷ MP = (100 − D%) ÷ (100 + G%) is derived by equating the two expressions for Selling Price.

Mark-up Percentage

Mark-up is the extra price added to CP to reach MP. Mark-up% = (MP − CP) ÷ CP × 100.

Shortcut Trick

In a proportion a : b :: c : d, the relationship can be seen between terms.

Observe the first and third terms: 19 → 38 (multiplied by 2).

Apply the same multiplier to the second term to find the fourth term.

Fourth proportional = 23 × 2 = 46.

∴ The correct answer is 46.

Alternate Method

Given: First term (a) = 19, Second term (b) = 23, Third term (c) = 38.

Formula Used: If a, b, c, and d are in proportion, then a/b = c/d or Product of Extremes = Product of Means (a × d = b × c).

Let the fourth proportional be x.

⇒ 19 : 23 :: 38 : x

⇒ 19/23 = 38/x

⇒ x = (23 × 38) / 19

⇒ x = 23 × 2

⇒ x = 46

∴ The correct answer is 46.

Additional Information

Mean Proportional

The mean proportional between two numbers a and b is given by √(a × b).

Third Proportional

If a, b, and c are in continued proportion (a : b :: b : c), then the third proportional c = b² / a.

Invertendo Property

If a : b = c : d, then b : a = d : c. This is used to simplify ratios by reciprocating both sides.

Alternendo Property

If a : b = c : d, then a : c = b : d. This allows swapping the internal terms of the proportion.

Given:

Increased(a) = 15%

Decreased(b) = -15%

Formula Used:

Net percentage = a + b + ab/100

Calculations:

According to the formula,

Net percentage = a + b + ab/100 = 15 + (-15) + 15 x (-15)/100 = 0 - 2.25 = -2.25%

here, the Negative sign represents the decrease in its price

Hence, The net percentage decreased is 2.25%

Given:

Kiran takes 2 hours to extract as much juice as Vishal can in 3 hours

 Dinesh takes 5 hours to extract as much juice that Kiran extracts in 4 hours

A tank can be filled with juice in 48 hours, if all of them work together

Calculations:

According to the question,

The ratio of Efficiency of Kiran and Vishal = 3:2 

Ratio of Efficiency of Dinesh and Kiran =  4:5  

The Efficiency of  Vishal: Kiran: Dinesh = 10: 15: 12

Work done can done in one day = 10 + 15 + 12 = 37

They Together complete the work in 48 hours,

Total Work = 37 x 48 = 1776

Work done by Dinesh alone = Total Work / Efficiency = 1776 / 12 = 148

∴ Hence, The work done by Dinesh alone in 148 hours

Shortcut Trick

Increment% = (Increment/value in 2010) x 100

Calculations:

For the chocolate A

⇒ Increment = value in 2011 - value in 2010 = 780000 - 720000 = 60000

⇒ Increment% = (Increment/value in 2010) x 100 = 60000/720000 x 100 = 8.33%

For the chocolate B

⇒ Increment = value in 2011 - value in 2010 = 880000 - 850000 = 30000

⇒ Increment% = (Increment/value in 2010) x 100 = 30000/850000 x 100 = 3.52%

For the chocolate C

⇒ Increment = value in 2011 - value in 2010 = 740000 - 690000 = 50000

⇒ Increment% = (Increment/value in 2010) x 100 = 50000/690000 x 100 = 7.24%

For the chocolate D

⇒ Increment = value in 2011 - value in 2010 = 670000 - 580000 = 90000

⇒ Increment% = (Increment/value in 2010) x 100 = 90000/580000 x 100 = 15.51%

Hence, The chocolate B has encountered the minimum percentage increment

Shortcut Trick

Simple Interest for 1 year = 7% of ₹1,900 = 19 × 7 = ₹133.

Total Interest given = ₹798.

Time period = Total Interest ÷ Interest per year

Time = 798 ÷ 133 = 6 years.

∴ The correct answer is 6 years.

Alternate Method

Given:

Principal (P) = ₹1,900

Simple Interest (SI) = ₹798

Rate (R) = 7% per annum

Formula Used:

Simple Interest (SI) = (P × R × T) ÷ 100

Calculations:

⇒ 798 = (1900 × 7 × T) ÷ 100

⇒ 798 = 19 × 7 × T

⇒ 798 = 133 × T

⇒ T = 798 ÷ 133

⇒ T = 6

∴ The correct answer is 6 years.

Additional Information

Simple Interest (SI)

It is the interest calculated only on the Principal amount for the entire period. Formula: SI = (P×R×T)/100.

Amount (A)

The total sum of money returned after the time period, calculated as Amount = Principal + Simple Interest.

Effective Rate of Interest

For Simple Interest, the total percentage increase over T years is simply (R × T)% of the Principal.

Rate and Time Relationship

If the SI and Principal are constant, the Rate is inversely proportional to Time (R ∝ 1/T).
