Using below symbol table we can draw family tree diagram:

From the given information,

1. A and B are the brothers of C.

2. B is the son of D and E, D is the daughter of F. (implying D is the mother and E is the father of B)

3. P is the father-in-law of E (implying P is the father of D and F is the mother of D) 

4. Q is the son of F (implying Q is the brother of D)

The family tree that can be drawn using these information are as follows:

Hence, A is the grandson of P.

In the given figure the sum of the position value of opposite faces is 19

Place value of R = 18

Place value of A = 1

Sum of position values of R and A = 18 + 1 = 19

Similarly, Position value of G + L = 7 +12 = 19

Therefore, the sum of place values of I and ? will also be 19.

So, 

I + ? = 19

9 + ? 19

? = 10 = J

Hence, the missing letter is J.

On applying these two properties on each option one by one we get,

1. (201, 702, 303)

Property 1: sum of the digits of the third number = 3 + 3 = 6 and sum of the digits of first number = 2 + 0 + 1 = 3 Here, this property is verified.

Property 2: sum of the digits of second number = 7 + 2 = 9 and sum of the digits of first number = 2 + 0 + 1 = 3 Here this property is verified.

2. (400, 660, 800)

Property 1: sum of the digits of the third number = 8 + 0 + 0 = 8 and sum of the digits of first number = 4 + 0 + 0 = 4 Here, this property is verified.

Property 2: sum of the digits of second number = 6 + 6 + 0 = 12 and sum of the digits of first number = 4 + 0 + 0 = 4 Here this property is verified.

3. (200, 600, 300)

Property 1: sum of the digits of the third number = 3 + 0 + 0 = 3 and sum of the digits of first number = 2 + 0 + 0 = 2 Here, this property is not verified.

Property 2: sum of the digits of second number = 6 + 0 + 0 = 6 and sum of the digits of first number = 2 + 0 + 0 = 2 Here this property is verified.

4) (111, 207, 222)

Property 1: sum of the digits of the third number = 2 + 2 + 2 = 6 and sum of the digits of first number = 1 + 1 + 1 = 3 Here, this property is verified.

Property 2: sum of the digits of second number = 2 + 0 + 7 = 9 and sum of the digits of first number = 1 + 1 + 1 = 3 Here this property is verified.

Hence, option 3  does not follow these properties.

On interchanging the signs '+' and '×' and the numbers '4' and '8' are interchanged. 

Checking each option one by one 

1. 12 × 4 + 8 = 34

After interchanging the signs '+' and '×' and the numbers '4' and '8'

= 12 + 8 × 4 = 34

= 12 + 32 = 34

= 44 ≠ 34

2. 6 + 8 × 4 = 38

After interchanging the signs '+' and '×' and the numbers '4' and '8'

= 6 × 4 + 8 = 38

= 24 + 8 = 38

= 32 ≠ 38

3) 2 × 4 + 8 = 34

After interchanging the signs '+' and '×' and the numbers '4' and '8'

= 2 + 8 × 4 = 34 

= 2 + 32 = 34

= 34 = 34

4. 4 + 8 × 2 = 32

= 8 × 4 + 2 = 32

= 32 + 2 = 32

= 34 ≠ 32 

Hence, Only option 3 satisfies the condition

Given positions of the same dice,

When the mirror is placed right side of the figure, then only the left and right sides of the image will be interchanged. Thus, the mirror image will be as follows:

Hence, the correct mirror image for the diagram will be only option 3.

Let us name this triangle.

We get triangles namely ABC, ABD, ABE, ABF, ACD, ACE, ADF, AEF, ADE, ACF

Hence, there are 10 triangles in this given figure.

The given codes are as follows:

 

 

 

Hence, we get the following codes for the Alphabets:

L - 2, O - 5, R - 3, D - 4

Hence, the code for the word LORD is 2534.

The pattern followed here is,

Similarly,

Hence, KINDLE Will be coded as 'MGPBNC'.

Given,

29 : 838 :: 14 : ?

The pattern followed here is,

29² - 3 = 841 - 3 = 838

Similarly,

14² - 3 =  196 - 3 = 193

Hence, 193 is the correct answer.

Each letter-clusters contain only consonant in it but, only 'ET' contains a vowel 'E' in it.

Hence, 'ET'  is different from the rest three.

According to the English Alphabet series and the positional values:

The pattern followed here is, 

Hence, 'HPX' Will come next in the series.

'Myopia' is a disease related to the eye in the same way 'Pyorrhea'  is a disease related to the gums.

Hence, Gums is the correct answer to this question.

Given,

4 (15) 1; 7 (22) 3; ? (57) 4

The pattern followed here is,

4²- 1³ = 15

7²- 3³ = 49 - 27 = 22

Similarly,

?² - 4³ = 57

?²  - 64 = 57

?²  = 64 + 57

?² = 121

? = 11

Hence, 11 will replace question mark in the given pattern.

Given,

1, 4, 9, 15, 25, 36

The pattern followed here is, 

1² = 1   

2² = 4

3² = 9

4²  = 16 ≠ 15

5² = 25

6² = 36

Clearly, 15 is not a perfect square of 4.

Hence, 15 does not belong to this series.

The shaded part represents the students who play any two of the three sports which is shown below:

Hence, the students who play any two of the three sports are 6 + 5 = 11.

Out of the four triads three triads follow a pattern

1) (273, 546, 819)

273 = 2 + 7 + 3 = 12

546 = 5 + 4 + 6 = 15

819 = 8 + 1 + 9 = 18

2) (291, 438, 657)

291 = 2 + 9 + 1 = 12

438 = 4 + 3 + 8 = 15 

657 = 6 + 5 + 7 = 18

3) (326, 654, 981)

326 = 3 + 2 + 6 = 11

654 = 6 + 5 + 4 = 15

981 = 9 + 8 + 1 = 18

4) (192, 384, 576)

192 = 1 + 9 + 2 = 12

384 = 3 + 8 + 4 = 15

576 = 5 + 7 + 6 = 18

sum of digits of first number in triad is 12

sum of digits of second number in triad is 15

and, sum of digits of third number in triad is 18

on checking, option 3

the first number 326 = 3 + 2 + 6 = 11

654 = 6 + 5 + 4 = 15

981 = 9 + 8 + 1 = 18

Hence, option 3  is different from the given number triads.

The option in which the given figure is embedded is:

Hence, option 4 contains the given figure.

The least possible Venn diagram for the given statements is as follows:

Conclusions:

Given,

6, 10, 18, 34, ?

The pattern followed is,

Hence, 66 will replace the question mark.

While writing all the natural numbers from 1 to 100, 6 comes at different places such as 

6, 16, 26, 36, 46, 56, 66, 76, 86, 96, 60, 61, 62, 63, 64, 65, 67, 68, 69.

Hence, 6 comes 20 times while writing from 1 to 100.

Note: In 66 there are two 6's in 66.

In the mirror image, the top and the bottom part of the figure remain the same, and the left and the right part of the figure interchange.

   

             

Hence, the correct answer is option(2).

Given:

⇒ Number of cricket playing student = 23% of 2800 = 644 

⇒ Number of Kabaddi playing student = 12% of 2800 = 336 

Calculation:

⇒ Number of cricket playing student after 24 student remove = 620 

⇒ Number of kabaddi player after 24 student added = 360

⇒ New ratio of the number of students in Cricket and Kabaddi playing student = 620 : 360 = 31 : 18 

∴ The required ratio is  31 : 18 .

Given 

Malti bought a TV = Rs 8800 

Formula Used 

Selling price = [cost price × (100 + p%)]/100

Calculation 

⇒ Let the cost price of TV is x

⇒ (x/100) × 110 = 8800 

⇒ x = 8,000

∴ The original cost of the TV is Rs 8000

Alternate Method 

Calculation:

Let the cost price be Rs. 100

GST is 10% and applied on cost price,

Cost price after GST,

⇒ 100 + 10% of 100

⇒ 100 + 10

⇒ 110

According to the question,

⇒ 110 = 8,800

⇒ 1 = 8,800/110 = 80

Actual cost price is,

⇒ 80 × 100

⇒ 8,000

∴ The original cost of the TV is Rs 8000

Given 

x3 + y3 = 16

x + y = 4

Formula Used 

x3 + y3 = (x + y) (x2 – xy + y2)

x4 + y4 = (x2 + y2)2 - 2x2y2

Calculation 

⇒ x³ + y³ = (x + y) (x² – xy + y²)

⇒ Putting given values of x³ + y³ and (x + y)

⇒ 16 = 4 × ((x+y)² – 3xy)

⇒ 16 = 4 × (16 – 3xy)

⇒ 16 = 64 – 12xy

⇒ 12xy = 48

⇒ xy = 4

⇒ x⁴ + y⁴ = (x² + y²)² - 2x²y²

⇒ (x² + y²)² – 2 × 16

⇒ ((x + y)² – 2xy)² – 2 × 16

⇒ (16 – 8)² – 2 × 16

⇒ 64 - 32 = 32

∴ x⁴ + y⁴ is 32.

Given 

$\frac{4}{3}\left(x^2 + \frac{1}{x^2}\right) = 110 \frac{2}{3}$

Formula Used 

If x² + 1/x² = a

then x - 1/x = √(a² - 2) = b

and also x³ - 1/x³ = b³ + 3b 

Calculation 

(4/3)(x² + 1/x²) = (332/3)

⇒ (x2 + 1/x2) = (332/3) × (3/4) 

⇒ x² + 1/x² = 83

⇒ x - 1/x = √(83 - 2) = √81 = 9 

⇒ x³ - 1/x³ = 9³ + 3(9) = 729 + 27 = 756 

⇒ 1/9(x3 - 1/x³) = 84

Given 

Radius of circle = 10 cm 

Formula Used 

(Hypotnuese)² = (perpendicular)² + (Base)²

Calculation 

⇒ BP = BR and CR = CQ 

⇒Perimeter of ΔABC = AB + BR + RC + CA

and

BP = BR and RC = CQ   [equal tangent theorem]

Equal Tangent Theorem: This theorem states that if from one external point, two tangents are drawn to a circle then they have equal tangent segments. 

So

⇒ AB + BP + QC + CA

= AP + QA    (AP = QA, From equal tangent theorem) 

⇒2AP

⇒ In ΔAPO

⇒AO²=AP²+PO²

⇒26² = AP² + 10²

⇒ AP² = 576

⇒ AP = 24

⇒ The perimeter of the ΔABC = 2 x 24 = 48 cm

Given:

 [7 + 7 × ( 7 + 7 ÷ 7)] + 7 ÷ 7. 

Concept used:

Calculation:

⇒ [7 + 7 × ( 7 + 7 ÷ 7)] + 7 ÷ 7.

⇒ [7 + 7 × (7 + 1)] + 1

⇒ 63 + 1 = 64 

∴ The value is 64.

Given 

Area of ΔABC = 136 cm²

Formula Used   

Area of equilateral triangle = √3(a²/4) , where a is the side of the triangle.

Calculation

If each side of ΔABC = 2x unit

Then, Area of ΔABC = √3 x²      ---- (1)

Now, BD = BC/2 ( given)

⇒  BD = 2x/2 = x

So, area of equilateral triangle BDE =√3x²/4      ---- (2)

⇒ By dividing (1) by (2)

⇒ ar(ΔABC)/ar(ΔBDE) = (√3x²)/(√3x²/4) = 4/1

⇒  4 : 1 

⇒ Area of ΔABC = 136 

⇒ 4x = 136 

⇒ x = 34 

∴ The area of ΔBDE is 34 cm²

Given 

Cos 3θ = Sin (θ - 34°)

Formula used 

sin (90° - θ) = cos θ

Calculation 

⇒  sin (90 -3θ) = sin {(θ - 34)}

⇒ 90°  - 3θ = θ - 34° 

⇒ θ = 31° 

∴ θ = 31°

Given 

 Rahul and Mithun travel  = 30 km 

Sum of their speed = 70 km/h

Formula used 

Distance = speed × time 

Calculation 

let the speed of rahul = s 

⇒ speed of mithun = 70 - s 

⇒ total time = 2(6/60) hr = 21/10 hr 

⇒ 30/s + {30/(70 - s)} = 21/10 

⇒ s² - 70s + 1000 = 0

⇒ s² - 50s - 20s + 1000 = 0 

⇒ s(s - 50) - 20(s - 50) = 0 

⇒ (s - 50) (s - 20) = 0 

⇒ s = 50 km/hr , s = 20 km/hr 

when speed of Rahul = 50 km/hr , speed of mithun = 20 km/hr 

when speed of mithun = 50 km/hr , speed of rahul = 20 km.hr 

∴ The difference of their speed is 30 km/hr

Given:

The production of fertilizers in 1998 = 45 tonnes 

The production of fertilizers in 1999 = 65 tonnes 

Concept used:

Percentage = (actual value)/(comparison value) × 100 

Calculation:

Increase in the production of fertilizers from 1998 to 1999  = 20

Percentage increase in the production of fertilizers from 1998 to 1999  = (20/45) × 100 = 44.4% 

∴ The percentage increase in the production of fertilizers from 1998 to 1999 is 44.4%

Given:

√3cosθ = sinθ

calculation:

⇒ sinθ/cosθ = √3

⇒ tanθ = √3

⇒ θ = 60° 

Then, $\frac{4sin^2 θ - 5 cos θ}{3 cos θ + 1}$ = [4(√3/2)² - (5/2)]/[(3/2) + 1] 

⇒ (1/2)/(5/2) = 1/5 

∴ The required value is 1/5.

Given 

Δ ABC is an isosceles triangle , AB = AC 

Ad = 6 cm 

Formula used 

Area of triangle = 1/2 × base × height 

Figure:

Calculation:

Let, Base = b, and two equal sides = a 

According to the given data,

⇒ 2a + b = 36     ---(1)

⇒ 2a = 36 - b

⇒ a = (36 - b)/2     ---(2)

Now, AD perpendicular to BC ,so ΔADB is a right angle triangle.

So, AB² = AD² + BD²

⇒ a² = 6² + (b/2)²

⇒ a2 = 36 + b²/4

⇒ a2 - b2/4 = 36 

⇒ 4a2 - b2 = 36 × 4

⇒ (2a + b) (2a - b) = 144

Putting the value of (2a + b) from equation (1),

⇒ 36 × (2a - b) = 144

⇒ 2a - b = 4

Putting the value of b from equation (2),

⇒ 2 × (36 - b)/2 - b = 4

⇒ (36 - b) - b = 4

⇒ 36 - 2b = 4

⇒ 2b = 36 - 4 

⇒ b = 32/2 = 16 cm

So, the area of the Δ ABC = 1/2 × 16 × 6 = 48 cm²

∴ Area of triangle ABC is 48 cm2

Shortcut Trick

AD perpendicular to BC ,so ΔADB is a right angle triangle

We know the triplet  (6,8,10) 

so AB= 10 , AD = 6 cm and BD = 8 cm 

BC = 2 × BD      (In isosceles triangle, altitude and median are same)

BC = 16 cm 

Area of triangle ABC  = 1/2 × 16 × 6 = 48 cm²

∴ Area of triangle ABC is 48 cm2

Formula used 

Cost price = (selling price)/(100 + profit%) × 100

Calculation 

Let the cost price of article 100x 

Sell at 12% loss  = 88x 

Sell at 6% gain = 106x 

106x - 88x = 630 

⇒ x = 630/18 = 35 

⇒ 100x = 100 × 35 = 3500 

∴ The cost price of article is Rs 3500

Given:

The number of students enrolled in hockey = 26% of 2800 

The number of students enrolled in Tennis = 14% of 2800 

Calculation:

The number of students enrolled in hockey = (26/100) × 2800 = 728 

The number of students enrolled in Tennis = (14/100) × 2800 = 392

Average number of students enrolled in Hockey and Tennis together = (728 + 392)/2 = 1120/2 

⇒ Average number of students enrolled = 560 

∴ The average number of students enrolled in Hockey and Tennis together is 560

Shortcut Trick

For 10% rate (1/10) over 3 years, let Principal = 10³ = 1000 units.

The difference (D) between CI and SI is given by the ratio: D = 3R + 1 (where R is the denominator 10).

⇒ Difference = 3(10) + 1 = 31 units.

Given 31 units = ₹558 ⇒ 1 unit = 558 ÷ 31 = 18.

Sum (Principal) = 1000 units × 18 = ₹18,000.

∴ The correct answer is ₹18,000.

Alternate Method

Given: Rate (R) = 10% per annum, Time (T) = 3 years, Difference (D) = ₹558.

Formula Used: Difference (D) = P(R/100)² × [(300 + R) / 100]

⇒ 558 = P × (10/100)² × [(300 + 10) / 100]

⇒ 558 = P × (1/10)² × (310 / 100)

⇒ 558 = P × (1/100) × (31/10)

⇒ 558 = P × (31 / 1000)

⇒ P = (558 × 1000) ÷ 31

⇒ P = 18 × 1000

⇒ P = 18,000

∴ The correct answer is ₹18,000.

Additional Information

Given 

The salary of each increased = Rs 4800 

Calculation 

let the salary of vipin and Dinesh be 5x and 8x

(5x + 4800)/(8x + 4800) = 7/10 

⇒ 50x + 48000 = 56x + 33600 

⇒ x = 14400/6 = 2400 

Vipin salary = 5x = 5 × 2400 = Rs 12000

∴ Vipin's salary is Rs 12000

Given: 

$p + \frac{1}{p}=112$

Calculation: 

p + 1/p = 112

p - 112 = -1/p      ----(1)

(p - 112)¹⁵ + 1/p¹⁵    

Putting the value of (p - 112) in equation (2), we will get

 [-(1/p)]¹⁵ + (1/p)¹⁵ 

⇒ -(1/p)¹⁵ + (1/p)¹⁵ = 0

∴ (p - 112)15 + 1/p15 = 0

Given 

The number which is divisible by 8 and 11 = 4M37094267N

Concept Used 

divisibility rule of 8 - if the last 3 digit of any number is divisible by 8, then the whole number divisible by 8 

divisibility rule of 11 - the sum of odd place digits - the sum of even place digits = 0 or 11 

Calculation 

67N last 3 digits of the number 

According to the rule of divisibility by 8, N should be 2 

So, the value of N = 2 

Now no. = 4M370942672

⇒ the sum of odd place digit - the sum of even digit place = 0 OR 11

⇒ (4 + 3 + 0 + 4 + 6+ 2) - (M + 7 + 9 + 2 + 7) = 11

⇒ M = 5

∴ The value of M = 5 and N = 2

Given 

The average of nine 2 digit number decreases by = 6

Formula Used 

Average = Sum of Observation/ No. of Observation

Calculation

Let the number be 10x+y

(Sum of eight numbers + 10x + y)/9 - 6 = (Sum of eight numbers + 10y + x)/9

⇒ (Sum of eight numbers + 10x + y) - 54 = (Sum of eight numbers + 10y + x)

⇒ 10x + y - 54 = 10y + x

⇒ 9x - 9y = 54

⇒ x - y = 6

∴ The difference between the digit of number is 6.

Given:

The values to be directly taken from the graph.

Calculation:

Average production of 2000 and 2001 = (50 + 75)/2 = 62.5

So, we have clearly seen from options, 

The average production of 2000 and 2001 is less than the average production of 2001 and 2002.

Given 

the difference of 2 positive number = 1020 

Calculation

⇒ Let two numbers be x and y resp.

⇒ 7.6% of x = 12.4% of y 

⇒ x : y = 31 : 19 

⇒ x - y = 1020 

⇒ 31a - 19a = 1020 

⇒ a = 1020/12 = 85 

⇒ sum of two numbers = 31a + 19a = 50a 

⇒ 50 × 85 = 4250

∴ The sum of two numbers is 4250

Given 

AB = 48 cm 

AC = 14 cm

Figure:

Formula used 

(Hypotnuese)² = Perpendicular²+ base²

Area of triangle = 1/2 × Base × Height 

Calculation 

Let OP = OQ = OR = radius = r cm 

BC² = AB² +AC²

⇒ BC = √(48² + 14²) = 50 cm 

Area of Δ ABC = area of Δ OAB + area of Δ OBC + area of Δ OAC 

⇒ 1/2 × 48 × 14 = 1/2 × [48r + 14r + 50r]

⇒  r = 48 × 14/(112) = 6 cm 

∴ The radius of incircle is 6 cm

Given 

Diameter of cylindrical wire = .6cm 

Formula Used 

Volume of cylinder = πR²H

Calculation 

1 dm = 10 cm

So, 3.96 dm³ = 3960 cm³

Volume of the cylinder = πR²l

3960 = (22/7) × (.6/2)² × l 

⇒ l = 14000 cm 

⇒ 1m = 100cm 

⇒14000 cm = 140 m 

∴ The length of cylindrical wire is 140 m

Given 

xsin3θ + ycos3θ = sinθ cosθ

xsinθ = ycosθ

Formula used 

sin²θ + cos²θ = 1

Calculation 

x sin³ θ + y cos³ θ = sin θ cos θ

⇒  (x sin θ) sin² θ + (y cos θ) cos² θ = sin θ cos θ

⇒ (x sin θ) sin² θ + (x sin θ) cos² θ = sin θ cos θ   ( y cos θ = x sin θ)

⇒ x sin θ(sin² θ + cos² θ) = sin θ cos θ

⇒ x sin θ = sin θ cos θ

⇒ x = cos θ     ----(1)

Again    x sin θ = y cos θ

⇒ cos θ sin θ  = y cos θ

⇒ y = sin θ      ----(2)

from (1) and (2)

⇒ x² + y² = sin2θ + cos2θ = 1

Given 

A and B  together can complete work = 15 days 

B and C together can complete work = 24 days 

Formula Used 

Work = time × efficiency 

Calculation 

Take LCM of (15, 24) = 120 

Let the total work be 120 

Efficiency of A and B = 120/15 = 8      ----(1)

Efficiency of B and C = 120/24 = 5      ----(2)

We know , A : C = 2 : 1      ----(3) 

From (1) and (2) 

⇒ A - C = 3 

By using (3) , efficiency of A  = 6 , B = 2 and C = 3

⇒ B alone can complete the work in days = 120/2 = 60 days 

∴ B alone can complete the work in days is 60 days
