From the given information, Family diagram will be-

Here, Naveen is Father-In-Law of the girl.

Hence, Option (1) is correct.

Four students are sitting on a bench.

i) Swathi is to the left of Reethu.

ii) Monica is to the right of Reetu. Ragavi is between Reethu and Monika.

Here, 2^nd from the left is Reetu.

Hence, Option (4) is correct.

The logic followed is:

12 : 72

72 = 12 × (12 ÷ 2)

72 = 12 × 6

72 = 72

Similarly,

missing term = 16 × (16 ÷ 2)

Missing term = 16 × 8 = 128 

Hence, Option (4) is correct.

The logic followed is:

The bottom number = sum of the square of all the first three numbers column-wise 

In column-wise operation:

Column 1:

274 = 92 + 72 + 122 

274 = 81 + 49 + 144

274 = 274

Column 2:

500 = 102 + 162 + 122 

500 = 100 + 256 + 144

500 = 500

Column 3:

1278 = 132 + 252 + 222 

1278 = 169 + 625 + 441

1278 = 1278

Similarly,

Column 4:

1321 = 142 + 152 + ?2 

1321 = 196 + 225 + ?²

1321 = 421 + ?²

?² = 1321 - 421

?² = 900

? = √900

? = 30

Hence, the correct answer is "30".

Additional Information

Given: Arya is 8 ranks ahead of Surya who ranks 26^th in a class of 42.

The total number of students in the class = 42.

Surya Rank = 26^th.

Thus, Arya's rank from the top = Surya's Rank - 8

Arya's rank from the top = 26 - 8 = 18^th.

Arya's rank from the last = Total students - Arya's rank from the top + 1

Arya's rank from the last = 42 - 18 +1

Arya's rank from the last = 25^th

Hence, Option (1) is correct.

The logic followed is:

Smell, Aroma, and Fragrance all are synonyms and NOT Physical sense.

But Feel is NOT the synonym of others and it is a physical sense.

Here, Feel is odd from the others.

Hence, Option (4) is correct.

For this question, We have to complete: the sentence is given in question as-

Now, 2560 value will be at place of-

5 × 2n-1 = 2560

2n-1 = 512

2n-1 = 2⁹ 

After comparing both terms power-

n - 1 = 9 

n = 10^th 

Hence, Option (2) is correct.

Statements:

I. Harish was born on an even date of the month → 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28

II. Harish’s birth date was a prime number → 2, 3, 5, 7, 11, 13, 17, 19, 23, 29

But we know that 2 is the smallest even prime number.

According to both statements we can say that on 2^nd February 2000 Harish was born.

Hence, Option (1) is correct.

Given is X > Y, Y > Z, and Z > W

After combining all the relations as-

X > Y > Z > W 

Option (1) W > X → False 

Option (2) X > Z → True → As per combined relation X > Y > Z > W 

Option (3) Y > W → True → As per combined relation X > Y > Z > W 

Option (4) X > W → True → As per combined relation X > Y > Z > W

For this question, the cube is given below-

Let this be the original cube. It is cut into small 64 cubes as shown above.

We will analyze this layer-wise.

1^st layer-

All cubes are painted so No. of unpainted cubes is 0.

2^nd layer-

Only side cubes are painted, internal 4 cubes (middlemost) are not painted so No. of unpainted cubes are 4.

3^rd layer-

Only side cubes are painted, internal 4 cubes (middlemost) are not painted so No. of unpainted cubes are 4.

4^th layer-

All cubes are painted so No. of unpainted cubes is 0.

Here, the Total No. of unpainted cubes are 4 + 4 = 8

Hence, Option (1) is correct.

Shortcut Trick

If a cube has been painted red, blue, and black on pairs of opposite faces and divide it into X parts.

1. Total number of cubes = X3

2. Cubes that have three faces painted = 8 (Because there are only 8 corners in the cube)

3. Cubes which has only two faces painted = (X - 2) × No of Edges (12)

4. Cubes that have only one face painted = (X - 2)2 × 6

5. Cubes which have no face painted = (X - 2)3

If it is cut into 64 smaller cubes of the same size

N = 64

n = 4

Cubes which have no face painted = (X - 2)3

⇒ ( 4 - 2)³

⇒ 2³

⇒ 8

Hence, the correct answer is "8".

Concept:

The unit digit of power of a number repeats itself every 4^th time

Calculation:

353 - 638 + 2756

⇒ (3)(13 × 4) + 1 - (6)(9 × 4) + 2 + (27)(14 × 4)

⇒ Unit digit will be determined by unit digit of (31 - 6² + 274) 

⇒ Unit digit of 31 = 3

⇒ Unit digit of 62 = 6

⇒ Unit digit of 274 = 1

Hence, unit digit will be (3 - 6 + 1) = - 2

Since unit digit can not be negative, we will add 10 to it because these numbers are in decimal form.

∴ Unit digit of (3)53 - (6)38 + (27)⁵⁶ = - 2 + 10 = 8

Calculation:

Given number = 625355

790² = 624100; 8002 = 640000

⇒ 625355 is somewhere between 7902 and 8002

Checking for 791² = 625681

⇒ 625355 is between 790² and 791²

625355 - 624100 = 1255

Hence, 1255 should be subtracted to make it a perfect square.

∴ Sum of digits = 1 + 2 + 5 + 5 = 13

Given:

​7 men earn Rs. 17640 working 7 hours a day in 8 days

Formula used:

(m1 × d1 × h1)/w1 = (m2 × d2 × h2)/w2

m = number of men

d = number of days

h = number of hours

w = work

Calculation:

According to the question:

(7 × 8 × 7)/17640 = (9 × 10 × 8)/w2

⇒ w2 = 32400

∴ 16 men working 6 hours a day for 10 days will earn Rs. 32400.

Calculation:

Let x = \(0.1\overline{8}\)

⇒ 10x = \(1.\overline{8}\)     ----eq.1

⇒ 100x = \(18.\overline{8}\)     ----eq.2

By subtracting eq.1 from eq.2:

90x = 17

⇒ x = 17/90

Let y = \(0.\overline {23}\)     ----eq.3

⇒ 100y = \(23.\overline {23}\)     ----eq.4

By subtracting eq.3 from eq.4:

99y = 23

⇒ y = 23/99

Let z = \(0.1\overline{83}\)

⇒ 10z = \(1.\overline{83}\)     ----eq.5

⇒ 1000z = \(183.\overline{83}\)     ----eq.6

By subtracting eq.5 from eq.6:

990z = 182

⇒ z = 91/495

\(0.1\overline{8}+0.\overline {23}-0.1\overline{83}\) = x + y - z

⇒ (17/90) + (23/99) - (91/495) = 47/198

∴ ​\(0.1\overline{8}+0.\overline {23}-0.1\overline{83}\)​ = \(0.2\overline{37}\)

Given:

A can complete the work in 10 days

B can complete the work in 15 days

C can complete the work in 20 days

B and C started working together and both left the work after 5 days.

Formula used:

The efficiency of a person is inverse of the time taken

Calculation:

Per day efficiencies of A, B, and C respectively are 1/10, 1/15, 1/20

Per day efficiencies of B and C working together = 1/15 + 1/20 = 7/60

⇒ 5 day work of B and C = 5 × (7/60) = 7/12

Remaining work after they left = 1 - (7/12) = 5/12

Let A will take n days to complete the remaining work alone

⇒ n/10 = 5/12

⇒ n = 25/6

∴ A will complete the remaining work in 25/6 days

Given:

When a person sells 12 articles, he incurs a profit equal to the cost price(CP) of 3 articles

Formula used:

Profit% = (Profit/CP) × 100

Calculation:

Let the CP of 1 article = c

Total CP = 12c

⇒ Profit = 3c

Profit% = (3c/12c) × 100

∴ Profit = 25%

Given:

Diagonal of the rectangle = 8√5 cm

Perimeter of the rectangle = 48 cm

Formula used:

Perimeter of a rectangle = 2(l + b)

Area of a rectangle = lb

Length of the diagonal of a rectangle = √l2 + b2

(x + y)2 = x2 + y2 + 2xy

Calculation:

48 = 2(l + b)

⇒ l + b = 24

√l2 + b2 = 8√5

⇒ l2 + b2 = 320

(l + b)2 = l2 + b2 + 2lb

⇒ 242 = 320 + 2lb

⇒ lb = 128

∴ Area of the rectangle = 128 cm2

Given:

The train's speed is 90 kmph without stoppage and 78 kmph with stoppage

Formula used:

Speed = distance/time

Calculation:

Let the distance be 1170 km(LCM of 90 and 78)

Time without stoppage = 1170/90 = 13 hours

Time with stoppage = 1170/78 = 15 hours

Difference in time 2 hours = 120 minutes

∴ Average halt per hour = 120/15 = 8 min/hr

The correct answer is 22.56%

Key Points Written down value method of depreciation: 

• It is also known as the Reducing Value Method.
• Under this method, depreciation is charged at a fixed rate on the reducing balance (i.e. cost less depreciation) every year.
• In other words, a fixed rate on the written down value of the asset is charged as depreciation every year over the expected useful life of an asset.
• A percentage known as rate of depreciation is applied to the book value and not to the cost of the asset.

Important Points

Given:

The value of the machine depreciates at the rate of 12% per annum

Present value of the machine = Rs. 36000

Calculation:

For 1^st Year

Depreciation = 36000 x 12/100 = 4320

Value at the end of first year = 36000 - 4320 = 31680

For 2^nd Year

Depreciation = 31680 x 12/100 = 3801.6

Value at the end of first year = 31680 - 3801.6 = 27878.4

Total Decrease in value = 4320+3801.6 = 8121.6

Percentage decrease in value = (Depreciation in 2 Years / Initial Value) x100

         = (8121.6 / 36000) x 100

         = 22.56 %

The percent decrease in its value at the end of two years is 22.56%

Given:

By selling the article at 3/4 of the original selling price(SP), the seller gains 8%

Formula used:

Gain = SP - CP

Gain% = (Gain/CP) × 100

CP = Cost price

Calculation:

Let the original SP be x and CP of the article be y

⇒ 3x/4 is the new SP

Gain at new SP = 0.08y; (8% of CP)

⇒ 0.08y = 3x/4 - y

⇒ 1.08y = 3x/4

⇒ x/y = 36/25

⇒ SP/CP = 36/25

⇒ Gain when article will be sold at original SP = 36 - 25 = 11 units

Gain% = (11/44) × 100 = 44

∴ Profit when sold at original price = 44%

Given:

Speed of stream(w) = 2.5 kmph

The boat can travel 15 km upstream and 50 km downstream in total 6 hours

Formula used:

Speed = distance/time

Upstream speed = b - w

Downstream speed = b + w

b = speed of boat in still water

Calculation:

According to the question:

15/(b - 2.5) + 50/(b + 2.5) = 6     ----eq.1

⇒ b2 - 37.5 = 15b + 37.5 + 50b - 125

⇒ 6b² - 65b + 50 = 0

⇒ (6b - 5)(b - 10) = 0

⇒ b = 10, 5/6

Since speed of the boat in still water can not be less than the speed of the stream, hence b = 5/6 rejected 

∴ Speed of the boat in still water = 10 kmph

Given:

All edges of the cube increased by 40%

Formula used:

Surface area(SA) of a cube = 6a²

a = length of the edge of the cube

Calculation:

Let the edge of the cube be a

⇒ SA = 6a²

Increased edge = 1.4a

⇒ Increased SA = 6(1.4a)² = 6a²(1.96)

∴ Percentage increase = [(1.96)6a² - 6a²]/6a² × 100 = 96%

Given:

Rs. 4342 is divided among A, B and C

2A = 5B = 6C

Calculation:

2A = 5B = 6C

⇒ Divide all by 30(LCM of 2, 5, 6)

⇒ A/15 = B/6 = C/5

⇒ A : B : C = 15 : 6 : 5

C's share = 5 units out of total 15 + 6 + 5 = 26 units

∴ Share of C = (5/26) × 4342 = Rs. 835

Given:

A and B contains spirit and water in the ratio of 3 : 8 and 6 : 5 respectively

They were further mixed in the ratio 1 : 2 

Calculation:

Spirit : water in A = 3 : 8

Spirit : water in B = 6 : 5 

Let 11 units of A and 22 units of B mixed together(as total of both quantities are factors of 11) 

Spirit in final mixture from A and B respectively = (3/11) × 11 + (6/11) × 22 = 3 + 12 = 15

Water in final mixture from A and B respectively = (8/11) × 11 + (5/11) × 22 = 8 + 10 = 18

∴ Water : spirit = 18/15 = 6 : 5

Given: 

HCF of two numbers = 18

Sum of the numbers = 270

Both the numbers are 3-digit numbers

Concept:

Co prime numbers are those numbers that have only 1 as their common factor 

Calculation:

Since 18 is the HCF of the numbers

Hence, numbers can be written in the form of 18x and 18y; where x and y are natural numbers and co-prime to each other

⇒ 18x + 18y = 270

⇒ x + y = 15

The pairs possible following the condition of co-prime:

(1, 14), (2, 13), (4, 11), (7, 8)

⇒ Pair of possible numbers:

(18, 252), (36, 234), (72, 198), (126, 144)

Hence, both 3-digit are in only one case (126, 144)

∴ Sum of their reciprocals = 1/126 + 1/144 = 5/336

Given:

Expression = \(\frac{138^2 + 156^2 + 194^2 - 138×156 + 156×194 + 194×138}{(13.8)^3 + (15.6)^3 - (19.4)^3 + 13.8×15.6×58.2}\)

Calculation:

Numerator = \(138^2 + 156^2 + 194^2 - 138×156 + 156×194 + 194×138\)

Denominator:

Write 13.8 = 138/10, 15.6 = 156/10, 19.4 = 194/10, 58.2 = 582/10

Denominator = \(\frac{138^3 + 156^3 - 194^3 + 138×156×582}{10^3}\)

Use algebraic formula:

We know \(^3 + b^3 - c^3 + 3abc = (a + b - c)(a^2 + b^2 + c^2 - ab + bc + ca)\)

Here, let a = 138, b = 156, c = 194

Denominator = \((138 + 156 - 194) × (138^2 + 156^2 + 194^2 - 138×156 + 156×194 + 194×138)× \frac{1}{10^3}\)

= 100 × numerator × \(\frac{1}{10^3}\)

Value = numerator / (100 × numerator × \(\frac{1}{10^3}\)) = 1 / 0.1 = 10

∴ The value of the given expression is 10.

Average of n numbers = Sum of all the numbers/n

Total marks of all students initially = 64 × 60 = 3840

Change in marks after correction = (24 + 76) - (42 + 28) = 30

Total correct marks = 3840 + 30 = 3870

∴ Correct average = 3870/60 = 64.5

Given:

If numerator increased by 170% and denominator decreased by 302, the fraction becomes \(\frac{81}{14}\)

Calculation:

Let fraction initially be x/y

Fraction after change = (x + x × 170%)/(y - y × 30%)

⇒ 2.7x/0.7y

According to the question,

2.7x/0.7y = 81/14

⇒ \(\frac{x}{y} = \frac{81 × 0.7}{14 × 2.7}\)

⇒ \(\frac{x}{y} = \frac{3}{2}\)

∴ The original fraction is \(\frac{3}{2}\).

Given:

 

Total number of students = 200

Maximum marks of the exam = 80

Concept:

The median of data is the centermost number of the data when arranged in ascending order

Calculation:

Total number of students = 200

Hence, the centermost number(marks) will be in 40-50 interval as it is having the 91^st, 92^nd and 93^rd numbers when arranged in ascending order

The total measure of the angle of the pie chart = 360º

∴ Central angle of pie chart for 40-50 interval = (40/200) × 360 = 72º

Given:

 

Total number of students = 200

Total marks of test = 80

Concept:

Mean is the average of a data

Calculation:

Total number of students = 200

Total marks of all students = (20 × 15) + (28 × 25) + (32 × 35) + (40 × 45) + (36 × 55) + (26 × 65) + (16 × 75) = 8920

∴ Mean = 8920/200 = 44.6
