Given that,

Number of ducks = 48

Number of goats = 42

Number of cows = 10

Let number of attendants = a

Each one has 1 head.

Number of feet of duck = 2

Total number of feet of 48 ducks = 48 × 2 = 96

Number of feet of a goat = 4

Total number of feet of 42 goats = 42 × 4 = 168

Number of feet of a cow = 4

Total number of feet of 10 cows = 10 × 4 = 40

Number of feet of an attendant = 2

Total number of feet of "a" attendants = 2a

Total heads = 48 + 42 + 10 + a

= 90 + 10 + a

= 100 + a

Total feet = 96 + 168 + 40 + 2a

= 264 + 40 + 2a

= 304 + 2a

According to given condition,

Total number of feet = Total number of heads + 216

(304 + 2a) = (100 + a) +216

304 + 2a = 100 + a + 216

304 + 2a = 316 + a

2a - a = 316 - 304

a = 12.

Therefore, total number of attendants = 12.

Hence, the correct answer is "12".

Taking in consideration first and second dice at a time,

Hence, the correct answer is "Option (2)".

The pattern followed here is,

In a column,

The dIfference between first number and middle number is divisible by 3.

The difference between middle number and third number is divisible by 4.

In First Column,

12 - 9 = 3 [3 x 1 = 3]

13 - 9 = 4 [4 x 1 = 4]

In Second Column,

33 - 12 = 21 [3 x 7 = 21]

40 - 12 = 28 [4 x 7 = 28]

In Third Column,

61 - 28 = 33 [3 x 11 = 33]

61 - 17 = 44 [4 x 11 = 44]

Hence, "61" is the correct answer.

Given that,

X is 7^th from the top and Y is 16^th from the bottom.

It means there are 6 students above X and 15 students below Y.

Now, after interchanging their positions,

X becomes 21^st from the top means there are 20 students above X.

But it is clear that there are 6 students above Y, so,

Students in between X and Y = 20 - 6 - 1 (Y) = 14 - 1 = 13.

Position of Y from bottom = 15 + 1 (X) + 13 + 1 (Y) = 30^th.

Hence, the correct answer is "30^th".

Key Points

• Hemoglobin (Hb) is a protein found in red blood cells that carries oxygen in your body and gives blood its red color.
• Hemoglobin levels vary from person to person. Men usually have higher levels than women.
• With the assistance of external chemical factors, the Hemoglobin molecules take up oxygen molecules within the lungs and then send them to our body's varied tissues.
• Iron is the main constituent of hemoglobin.
• The normal Hb level for males is 14 to 18 g/dl; females are 12 to 16 g/dl.

Additional Information

• The biggest regulator of oxygen affinity in Hemoglobin is that the oxygen itself.
• If in the lungs, the oxygen levels are high, the Hemoglobin shows a greater affinity towards the oxygen molecules, and as it bounds to more oxygen, this property of affinity increases and vice versa.
• When the Oxyhemoglobin binds to the utmost capacity, it becomes saturated, but its affinity towards oxygen increases, whereas when this binding loose oxygen molecule, the affinity decreases.
• This regulation activity is named Cooperativity. It is a crucial function because it allows the utmost amount of Hemoglobin to be carried to the tissues and allows deoxyhemoglobin, releasing the oxygen tissue.

Identity used:

(a³ + b³) = (a + b) × (a² + b² – ab)

Calculation:

$\frac{{5.35 × 5.35 × 5.35 + 3.65 × 3.65 × 3.65}}{{53.5 × 53.5 + 36.5 × 36.5 - 53.5 × 36.5}}$

$\frac{({5.35 × 5.35 × 5.35 + 3.65 × 3.65 × 3.65)}}{{(53.5 × 53.5 + 36.5 × 36.5 - 53.5 × 36.5)}}$

$\frac{({5.35 × 5.35 × 5.35 + 3.65 × 3.65 × 3.65)}}{{(53.5 × 53.5 + 36.5 × 36.5 - 53.5 × 36.5)}}$

$⇒ {\frac{{(5.35 )^3 + (3.65)^3}}{{((53.5)^2 + (36.5)^2 - 53.5 × 36.5)}}}$

$⇒ \frac{{ {(5.35 : + :3.65) \times [(5.35)^2 + (3.65)^2 - 5.35 × 3.65}]}}{{100 \times [(5.35)^2 + (3.65)^2 - 5.35 × 3.65}]}$

The ladder leaning against the wall making an angle θ with the horizontal ground such that tan θ = 12/5. The height of the top of the ladder from the wall is 24 m

Concept Used:

tanθ = Height/Base

Calculation:

Accordingly,

Let the base = x that means the distance of the foot of the ladder from the wall is x

tanθ = 12/5

⇒ 24/x = 12/5

⇒ x = 10

∴ The distance of the foot of the ladder from the wall is 10 m

Given:

BD ⊥ AC at D.

E is a point on BC such that ∠BEA = x°

∠EAC = 62°

∠ EBD = 60°

Calculations:

In ΔAOD,

∠AOD + ∠ADO + ∠DAO = 180°

⇒ ∠AOD + 90° + 62° = 180°

⇒ ∠AOD = 180° - 152°

⇒ ∠AOD = 28°

∵ ∠AOD and ∠EOB are vertical opposite angles,

∠AOD = ∠EOB = 28°

In ΔBOE,

∠BEO + ∠EOB + ∠OBE = 180°

⇒ x° + 28° + 60° = 180°

⇒ x° = 180° - 88°

⇒ x° = 92°

∴ The value of x is 92°.

Given:

Radius = 14 cm

Volume = 6160 cm³

Formula used:

(i) Volume of cylinder = π × r² × h

(ii) Curved surface area = 2 × π × r × h

Calculation:

Volume = π × r² × h

⇒ 6160 = (22/7) × (14)² × h

⇒ h = (6160 × 7)/(22 × 196)

⇒ h = 10 cm

Curved surface area = 2 × π × r × h

⇒ 2 × (22/7) × 14 × 10

⇒ 2 × 22 × 2 × 10

⇒ 880 cm²

∴ The curved surface area is 880 cm²

Given:

Average of twelve numbers = 39

Average of last five numbers = 35

Average of first four numbers = 40

Fifth number = sixth number - 6

Fifth number = seventh number + 5

Formula used:

Average = (Sum of values)/(Number of values)

Calculations:

Let twelve numbers be x₁, x₂, x₃, x₄, x₅, x₆, x₇, x8, x9, x10, x11, x₁₂.

x5 = x6 - 6      ----(i)

x5 = x7 + 5      ----(ii)

Average of first four numbers,

(x1 + x2 + x3 + x₄)/4 = 40

⇒ (x1 + x2 + x3 + x4) = 160

Average of last five numbers,

(x₈ + x₉ + x₁₀ + x₁₁ + x₁₂)/5 = 35

⇒ (x8 + x9 + x10 + x11 + x12) = 175

Average of twelve numbers,

(x1 + x2 + x3 + x4 + x5 + x6 + x7 + x8 + x9 + x10 + x11 + x12)/12 = 39

⇒ (x1 + x2 + x3 + x4 + ​x5 + x6 + x7 + x8 + x9 + x10 + x11 + x12) = 468

⇒ (160 + ​x5 + x6 + x7 + 175) = 468

⇒ ​x5 + x6 + x7 = 468 - 160 - 175

⇒ ​x5 + x6 + x7 = 133      ----(iii)

Putting value of x₅ from equation (i),

⇒ x6 - 6 + x6 + x7 = 133

⇒ 2x6 + x7 = 139

⇒ x7 = 139 - 2x6      ----(iv)

Putting value of x5 from equation (ii),

x7 + 5 + x6 + x7 = 133

⇒ 2x7 + x6 = 128

⇒ 2(139 - 2x6) + x6 = 128

⇒ 278 - 4x₆ + x₆ = 128

⇒ 3x₆ = 150

⇒ x₆ = 50

Putting the value of x₆ in equation (iv),

x7 = 139 - 2x6

⇒ x7 = 139 - 2(50)

⇒ x7 = 139 - 100

⇒ x7 = 39

Average of x₆ and x₇ = (50 + 39)/2

⇒ 89/2

⇒ 44.5

∴  The average of the sixth and seventh numbers is 44.5

Alternate MethodSum of values = Avg × Number of values

Sum of 12 numbers = 39 × 12 = 468

Sum of last 5 numbers = 35 × 5 = 175

Sum of first 4 numbers = 40 × 4 = 160

Sum of 9 numbers = 175 + 160 = 335

Sum of 5th + 6th + 7th numbers = Sum of 12 numbers - Sum of 9 numbers

⇒ 468 - 335

⇒ 133

According to the question,

Let 5th number be x.

Then, 6th number = x + 6, and 7th number = x - 5

Sum of 5th + 6th + 7th numbers = 133

⇒ x + x + 6 + x - 5 = 133

⇒ 3x = 133 - 1

⇒ x = 132/3 = 44

Average of 6th number + 7th number = (x + 6 + x - 5)/2 

⇒ (2x + 1)/2

⇒ (2 × 44 + 1)/2

⇒ 89/2

⇒ 44.5

∴  The average of the sixth and seventh numbers is 44.5

Given:

4 - 2sin2θ - 5cosθ = 0

Formula used:

sin²θ + cos²θ = 1

Calculation:

4 - 2sin2θ - 5cosθ = 0

⇒ 4 - 2(1 - cos2θ ) - 5cosθ = 0

⇒ 4 - 2 + 2cos2θ - 5cosθ = 0

⇒ 2cos2θ - 5cosθ + 2 = 0

⇒ cosθ = [5 ± √(25 - 16)]/4

⇒ cosθ = (5 ± 3)/4

⇒ cosθ = 2 or 1/2

cosθ can't more than 1, cosθ = 1/2

tanθ = √3

cosθ - tanθ

⇒ (1/2) - √3

⇒ $\frac{{1 - 2\surd 3}}{2}$

∴ The value is $\frac{{1 - 2\surd 3}}{2}$.

Given:

Total student in 2008, 2012, 2013 together from school A = 640 + 900 + 750

Total student in 2009, 2010, 2011 together from school B = 820 + 600 + 750

Concept used:

Using the concept ratio

Calculation:

Total student in 2008, 2012, 2013 together from school A = 640 + 900 + 750

⇒ Required sum of A = 2290

Total student in 2009, 2010, 2011 together from school B = 820 + 600 + 750

⇒ Required sum of B = 2170

Required ratio = 2290 ∶ 2170

⇒ Required ratio = 229 ∶ 217

∴ The required ratio is 229 ∶ 217.

Given:

Calculation:

Number of students in the class interval 165-170 = 14

Number of students in the class interval 150-155 = 15

Difference = 15 – 14 = 1

Required percentage = (1/15) × 100

⇒ Required percentage ≈ 6.7%

∴  The number of students in the class interval 165-170 is 100/15 = 6.7% less than the number of students in class interval of 150-155

Given:

Each discount = 20%

Single discount = Rs. 331.20

Concept used:

Using the concept of percentage.

Calculation:

Let the MP is Rs. x.

1st discount at MP = (100 – 20)% of x

⇒ 1st discount = 80% of x

⇒ 1st dicount = 80/100 × x

⇒ 1st dicount = 0.8x

2nd discount = (100 – 20)% of 0.8x

⇒ 2nd discount = 80% of 0.8x

⇒ 2nd dicount = 80/100 × 0.8x

⇒ 2nd dicount = 0.8 × 0.8x

⇒ 2nd dicount = 0.64x

Equivalent discount = x – 0.64x

⇒ 331.20 = 0.36x

⇒ x = 331.20/0.36

⇒ x = Rs. 920

∴ The marked price of an article is Rs. 920.
