Given:

Amount = Rs 9,261

Time = 3 years

Rate = 5% p.a.

Concept Used:

Amount = P$[1+\frac{r}{100}]^t$

Calculation:

⇒ Putting the values in the formula,

⇒ 9261 = P$\left[1+\frac{5}{100}\right]^3$

⇒ 9261 = P × $\frac{105}{100}\times \frac{105}{100}\times \frac{105}{100}$

⇒ P = $\frac{9261\times 100\times 100\times 100}{105\times 105\times 105}$ = Rs 8,000

Therefore, the principal amount is Rs 8,000.

Given:

$\frac{1}{6} + \frac{1}{{12}} + \frac{1}{{20}} + \frac{1}{{30}}$

Calculation:

⇒ LCM of 6, 12, 20 and 30 = 180

⇒ $\frac{1}{6} + \frac{1}{{12}} + \frac{1}{{20}} + \frac{1}{{30}}$ = $\frac{30+15+9+6}{180}$

⇒ $\frac{30+15+9+6}{180}$ = $\frac{60}{180}=\frac{1}{3}$

Therefore, the simplified value of the fraction is $\frac{1}{3}$.

Given:

Parallel sides of isosceles trapezium = 20 cm and 34 cm

Non-parallel side length = 25 cm

Concept Used:

Area of Trapezium = 1/2 (a + b) × h, 

where a & b are the lengths of parallel sides, 

H is the perpendicular

Calculation:

Drawing perpendicular lines from opposite vertices on the opposite side, 

In Δ BQC, applying Pythagoras' theorem, 

⇒ BC² = BQ² + QC²

⇒ 25² =  BQ2 +  72

⇒ BQ2 = 625 - 49 = 576

⇒ BQ = √576 = 24

Using the formula, 

⇒ 1/2 (20 + 34) × 24

⇒ 54 × 12 

⇒ 648

∴ The area of the Trapezium is 648cm²

Given:

Two circles touch each other externally whose radius are 16 cm & 4 cm.

Concept used:

If two circles of radius r₁ & r₂ touch each other externally then the length of a simple common tangent is  $2× √{r_1 r_2}$ 

Calculation: 

The radius of the circles are 16 cm and 4 cm

Then, the simple common tangent AB is

⇒ $2× √{4× 16}$ 

⇒ 2 × √ 64

⇒ 16 

∴ The length of AB is 16 cm

Given:

Product of two numbers = 800

HCF = 20

Concept Used:

HCF × LCM = Product of two numbers

Calculation:

⇒ Putting the values in the equation, we get

⇒ 20 × LCM = 800

⇒ LCM = $\frac{800}{20}$ = 40

Therefore, the LCM of the numbers is 40.

Shortcut Trick

Third Proportional of a and b is given by b² ÷ a.

Here, a = 36 and b = 12.

Third Proportional = (12 × 12) ÷ 36 = 144 ÷ 36 = 4.

Square of the third proportional = 4² = 16.

∴ The correct answer is 16.

Alternate Method

Given: First number (a) = 36, Second number (b) = 12.

Formula Used: If a, b, c are in continued proportion, then a : b = b : c, where c is the third proportional.

⇒ 36 ÷ 12 = 12 ÷ x

⇒ 3 = 12 ÷ x

⇒ x = 12 ÷ 3 = 4

⇒ Required value = (Third Proportional)²

⇒ Required value = 4² = 16

∴ The correct answer is 16.

Additional Information

Mean Proportional

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

Fourth Proportional

If four numbers a, b, c, d are in proportion (a : b = c : d), then d = (b × c) ÷ a is the fourth proportional.

Duplicate Ratio

The duplicate ratio of a : b is a² : b².

Given:

3x2 + 1/ 2x2 = 2.5 

Formula used:

(a3 + b3) = (a + b)3 - 3ab(a + b)

Calculation:

⇒ (2.5)3 -  $3\times \frac{3x^2}{2x^2}\times 2.5$

⇒ 15.625 - 11.25

⇒ 4.375

∴ The answer is 4.375.

Given:

Radius of sphere = 7 cm

Concept Used:

Area of hemisphere = $3\pi r^2$

Calculation:

⇒ As sphere is cut into two halves, it becomes hemisphere.

⇒ Area of hemisphere = 3 × $\frac{22}{7}$ × 7 × 7

⇒ Area of hemisphere = 66 × 7 = 462 cm²

Therefore, the total surface area of each part of the sphere is 462 cm².

Given:

SP of an electric fan = Rs 1,800

Profit = Rs 200

Discount = 10%

Calculation:

⇒ Cost Price = 1800 – 200 = Rs 1,600

⇒ Let the printed value be x.

⇒ Selling Price = Printed Value – Discount

⇒ 1800 = x – 10% of x

⇒ 1800 = x – $\frac{10x}{100}$ = $\frac{10x-x}{10}$ = $\frac{9x}{10}$

⇒ x = $\frac{1800\times 10}{9}=2000$

⇒ When no discount is given, Profit = Printed Value – Cost Price

⇒ Profit = 2000 – 1600 = Rs 400

⇒ Profit % = $\frac{400}{1600}\times 100$ = 25%

Therefore, the profit percentage when no discount is given is 25%.

Given:

Number of language subjects = 2

Number of science subjects = 3

Average marks in language subjects = 65

Overall average marks = 72

Concept Used:

Average = Sum of all observations / Total number of observations

Calculation:

⇒ Total marks in language subjects = 65 × 2 = 130

⇒ Let the total marks in science subjects be x.

⇒ Overall average = $\frac{130+x}{3+2}=\frac{130+x}{5}$

⇒ 72 × 5 = 130 + x

⇒ x = 360 – 130 = 230

⇒ Average marks in science subjects = $\frac{230}{3}$ = 76.67

Therefore, the average marks in science subject is 76.67.

Given:

3 Men and 8 Women take total 75/8 days to complete the task

9 Men and 12 Women take total 25/7 days to complete the task

Calculation:

According to the question,

⇒ (3M + 8W) × 75/8 = (9M + 12W) × 25/7

⇒ $\frac{225M}{8}+75W=\frac{225M}{7}+\frac{300W}{7}$

⇒ 72 W = 9 M

⇒ M : W = 8:1

⇒ Total Work = [(9 × 8) + (12 × 1)] × 25/7

⇒ 84 × 25/7 = 300

⇒ 300 = 15 W

⇒ W = 20.

Therefore, 15 women will complete the work in 20 days.

Given:-

Present value =  2,652 Rs

<br>

Rate of interest = 4% 

<br>

The formula used:- 

<br>

Instalments (required sum ) 

<br>

= P.V. of Rs. due 6 months + P.V. of Rs. due 1 year hence two

<br>

Equal half-yearly instalments rate of interest first 6 month 

<br>

⇒ (r / 2) = 4 / 2 = 2 %

<br>

And the last 6-month rate of interest = 4 %

<br>

For Equal half-yearly instalments Present value

<br>

⇒ PV / 2 = 2652 / 2 =1326

<br>

Calculation:- 

Required sum

= P.V. of Rs. 1326 due 6 months + P.V. of Rs. 1326 due 1 year

<br>

Hence = $\frac {1326 \times 100}{100+4\times\frac {1}{2} }$ + $\frac {1326 \times 100}{100+4\times1 }$ 

<br>

⇒ $(1326\times100)(\frac {1}{102 } + \frac {1}{104} )$ 

<br>

⇒ $\frac {(1326\times100\times206)}{102\times104}$ 

<br>

⇒ Rs. 2,575 ( Installments ) 

<br>

∴ The required value is 2575.

Alternate MethodFormula used:

PV = PV of 1326 for 6 months + PV of 1326 for 1 year

PV = $\frac{A \space \times \space 100} {100 \space + \space r \space \times \space t} + \frac{A \space \times \space 100} {100 \space + \space r \space \times \space t}$

Calculation:

Since 2,652 is payable in two equal half-yearly instalments,

Amount (A) = 2652/2 = 1326

⇒ PV =  $\frac{1326 \space \times \space 100} {100 \space + \space 4 \space \times \space 1/2} + \frac{1326 \space \times \space 100} {100 \space + \space 4 \space \times \space 1}$

⇒ 1300 + 1275

⇒ 2575

Given:-

<br>

[ A2 -B2 = ( A+B )(A - B)]

<br>

cos²A + sin²A  =1 [ cos² A =1 -  sin2A  , ⇒  cos2 A = (1 + sin A )( 1 - sin A ) ⇒ $1 \over (1+ Sin A)$ =$(1 - Sin A)\over Cos^2A$ ]

<br>

Calculation:-

<br>

⇒  $\frac{{co{t^2}A\left( {secA - 1} \right)}}{{1 + sinA}}$

<br>

= $\frac{{\left( {secA - 1} \right)}}{{(1 + sinA)ta{n^2}A }}$                     [ ∵  cot A = 1 / tanA ]

<br>

⇒ $\frac{{\left( {secA - 1} \right)}}{{(1 + sinA)(se{c^2}A-1) }}$                     [  ∵ 1 + tan2 A = Sec2 A   ⇒ tan2 A = Sec2 A  - 1 ]

<br>

⇒ $\frac{{\left( 1 \right)}}{{(1 + sinA)(se{c}A+1) }}$                [ ∵ Sec2 A -1 = ( Sec A  + 1)(Sec A - 1) ]

⇒ $(1 - Sin A)\over (Cos^2A)(1+Sec A)$                  [ ∵  $1 \over (1+ Sin A)$= $(1 - Sin A)\over Cos^2A$ ]

<br>

⇒ $\frac{{se{c^2}A\left( {1 - sinA} \right)}}{{\left( {1 + secA} \right)}}$

<br>

∴ The required answer is $\frac{{se{c^2}A\left( {1 - sinA} \right)}}{{\left( {1 + secA} \right)}}$

<br>

Additional Information ⇒ cos2A + sin2A  = 1

<br>

⇒ cos2 A = 1 -  sin2A  ,

Given:

$\frac{{{x^2} + 8x + 16}}{{2x - 2}} \times \frac{{{x^2} - 1}}{{{x^2} + 5x + 4}}$

x = 2022

Calculation:

⇒ Factorizing by splitting the middle terms, we get

⇒ $\frac{{{x^2} + 8x + 16}}{{2x - 2}} \times \frac{{{x^2} - 1}}{{{x^2} + 5x + 4}}$ = $\frac{{{x^2} + 4x+4x + 16}}{{2x - 2}} \times \frac{{{x^2} - 1}}{{{x^2} + x+4x + 4}}$

⇒ $\frac{{x(x+4)+4(x + 4)}}{{2x - 2}} \times \frac{{{x^2} - 1}}{{x(x+1)+4(x + 1)}}$

⇒ $\frac{{(x+4)(x + 4)}}{{2x - 2}} \times \frac{{(x+1)(x-1)}}{{(x+1)(x + 4)}}$

⇒ $\frac{{(x+4)(x + 4)}}{{2(x - 1)}} \times \frac{{(x+1)(x-1)}}{{(x+1)(x + 4)}}$

⇒ Cancelling the terms, we get

⇒ $\frac{{(x+4)(x + 4)}}{{2(x - 1)}} \times \frac{{(x+1)(x-1)}}{{(x+1)(x + 4)}}$ = $\frac{(x+4)}{2}$

⇒ $\frac{2022+4}{2}$ = 1013

Therefore, the required value when x = 2022 is 1013.

Given:

A Dealer cheats  by Purchasing an item =15%

A Dealer sells  an item = 10% 

Formula:

Selling Price =\(\frac{(100+Gain%)}{100} \times 100\)

Profit  = Selling Price - Cost Price

Profit% = $\frac{Profit}{Cost Price} \times 100$

Calculation:

Let the Cost price be Rs.100

New price = $\frac{(100+15)}{100} \times 100$

⇒ $\frac{(115)}{100} \times 100$

⇒ Rs.115

He gains again 10% more on New Price

Selling Price = 115 +115 of 10%

⇒ 115 + 11.5

⇒ 126.5

Profit =  126.5  - 100

⇒ 26.5

Profit% = $\frac{26.5}{100} \times 100$

Profit% =  26.5%

Therefore, the percentage profit gain he got is 26.5%.

Alternate MethodBy observing the question we can understand that he gets two successive gains of 15% and 10%.

First, gain 15% he gets at purchasing and 2nd 10% he gets at selling.

So, Total gain = 15 + 10 + 15 × 10/100 = 26.5%

Given:

Savings = Rs 1,100

Expenditure = 78% of income

Calculation:

⇒ Let the monthly income be Rs x.

⇒ Expenditure = 78% of x

⇒ Expenditure = $\frac{78}{100}$  × x = $\frac{39x}{50}$

⇒ Income = Expenditure + Savings

⇒ x = $\frac{39x}{50}$ + 1100

⇒ x – $\frac{39x}{50}$ = 1100

⇒ $\frac{50x-39x}{50}$ = 1100

⇒ 11x = 1100 × 50

⇒ x = $\frac{1100\times 50}{11}$ = Rs 5,000

Therefore, the monthly income of a man is Rs 5,000.

Given:

Rupa sells a computer to Shilpa at = 20% loss

Shilpa sells it to Neelima at = 20% profit

Paid amount by Neelima = Rs 24,000

Calculation:

⇒ Selling price of computer for Shilpa = Rs 24,000

⇒ Cost price of computer for Shilpa = $\frac{24000}{100+20}\times 100$ = Rs 20,000

⇒ Selling price of computer for Rupa = Rs 20,000

⇒ Cost price of computer for Rupa = $\frac{20000}{100-20}\times 100$ = Rs 25,000

Therefore, the amount Rupa paid for the computer is Rs 25,000.

Given:

Time taken by Amit to cover 400 m race = 44 seconds

Time taken by Beenu to cover 400 m race = 50 seconds

Calculation:

⇒ Distance covered by Beenu in 1 second = $\frac{400}{50}$ = 8 m

⇒ Distance covered by Beenu in 44 seconds = 8 × 44 = 352 m

⇒ Difference between the distance of Amit and Beenu after completion = 400 – 352 = 48 m

Therefore, When Amit finished the race, Beenu is 48 m behind the finishing line.

Given:

A is Twice as good as B

Let 'B' one day be x then A one day be 2x

A+B can complete the work = 14 days

Formula:

Work = Efficiency × Time

Calculation:

A+B one day work = $\frac{1}{14}$

A+B one day work = A's one day work + B's one day work

⇒ $\frac{1}{14} = x+2x$

⇒ $3x = \frac{1}{14}$

⇒ $x = \frac{1}{42}$

⇒ $2x = \frac{1}{42} \times 2$

⇒ $\frac{1}{21}$ 

A one day work = $\frac{1}{21}$

A can complete the work in 21days

B one day work = $\frac{1}{42}$

B can complete the work in 42 days

∴ The Correct Answer is A = 21days and B = 42days
