The correct answer is Leaves.

Key Points

• Evaporation in the water cycle: Evaporation is the process by which water changes from a liquid state to a gaseous state (water vapor). This process is a key component of the water cycle.
• Role of plants: Plants contribute to evaporation through a process called transpiration. Transpiration involves the release of water vapor from plant parts into the atmosphere.
• Leaves: The leaves of plants are primarily responsible for transpiration. Water absorbed by the roots moves up through the plant and is released through tiny openings called stomata present on the surface of leaves. Hence, leaves play a crucial role in evaporation during the water cycle.
• Branches, roots, and stems: While branches, roots, and stems are important for transporting water within the plant, they are not directly involved in the process of evaporation. They function as conduits to deliver water to the leaves. Hence, these parts are not directly responsible for evaporation.
• The process of transpiration is vital for maintaining the plant's internal water balance and facilitating nutrient transport. It also contributes to the overall water cycle by releasing water vapor into the atmosphere.
• Hence, the correct answer is Leaves.

Additional Information

• Transpiration:
• Transpiration is the process by which plants release water vapor into the atmosphere through the stomata in their leaves.
• It is estimated that about 10% of the moisture in the atmosphere is contributed by transpiration from plants.
• Water cycle:
• The water cycle is a natural process that involves the continuous movement of water between the earth's surface and the atmosphere.
• Key processes include evaporation, condensation, precipitation, infiltration, runoff, and transpiration.
• Transpiration is a significant contributor to evaporation, which forms clouds and eventually leads to rainfall.
• Stomata:
• Stomata are small openings found on the surface of leaves. They facilitate gas exchange and the release of water vapor during transpiration.
• The opening and closing of stomata are regulated by guard cells based on environmental conditions such as humidity, temperature, and light.
• Importance of transpiration:
• Transpiration helps in cooling plants, maintaining water balance, and enabling the transport of nutrients from roots to leaves.
• It also contributes to local weather and climate patterns by adding moisture to the air.

Important Points

• Features of transpiration:
• Transpiration rate is influenced by factors such as temperature, humidity, wind speed, and light intensity.
• Plants in arid regions often have adaptations to minimize transpiration, such as small leaves, thick cuticles, and reduced stomatal density.
• Applications of transpiration:
• Transpiration plays a vital role in agricultural practices. Monitoring transpiration rates helps in optimizing irrigation and water management.
• Understanding transpiration dynamics is essential in studying climate change and its impact on vegetation and ecosystems.

Given:

Ratio of sweets distributed among A, B, C, D, E = (1/2):(1/3):(1/4):(1/5):(1/7)

Formula Used:

To find the minimum total number of sweets, take the LCM of denominators and then find total parts.

Calculation:

Denominators = 2, 3, 4, 5, 7

⇒ LCM of 2, 3, 4, 5, 7 = 420

Now make all ratios with same denominator:

⇒ (1/2):(1/3):(1/4):(1/5):(1/7)

⇒ (210/420):(140/420):(105/420):(84/420):(60/420)

⇒ Ratio = 210 : 140 : 105 : 84 : 60

⇒ Total parts = 210 + 140 + 105 + 84 + 60

⇒ Total parts = 599

⇒ Minimum total sweets = 599

Minimum total number of sweets = 599

Given:

If speed is increased by 10 km/h, time reduced = 55 minutes

If speed is decreased by 8 km/h, time increased = 55 minutes

Formula Used:

Time = Distance / Speed

Calculation:

Let usual speed = x km/h

Distance = d km

Time taken at usual speed = d/x hours

If speed increased by 10 km/h ⇒ Time = d/(x + 10)

If speed decreased by 8 km/h ⇒ Time = d/(x - 8)

Given difference in both cases = 55 minutes = 55/60 = 11/12 hours

⇒ d/x - d/(x + 10) = 11/12 …(1)

⇒ d/(x - 8) - d/x = 11/12 …(2)

From (1): d = (11/12) × (x × (x + 10)) / 10

From (2): d = (11/12) × (x × (x - 8)) / 8

Equating both:

⇒ (x × (x + 10)) / 10 = (x × (x - 8)) / 8

⇒ 8(x² + 10x) = 10(x² - 8x)

⇒ 8x² + 80x = 10x² - 80x

⇒ 2x² - 160x = 0

⇒ x(x - 80) = 0

⇒ x = 80 (since speed ≠ 0)

Substitute in (1):

⇒ d = (11/12) × (80 × (80 + 10)) / 10

⇒ d = (11/12) × (80 × 90) / 10

⇒ d = (11/12) × 720

⇒ d = 11 × 60

⇒ d = 660 km

Distance = 660 km

Given:

Total score = 114 runs

Boundaries = 5

Sixes = 9

Formula Used:

Runs scored by running = Total score - (Runs from boundaries + Runs from sixes)

Percentage of runs scored by running = (Runs scored by running / Total score) × 100

Calculation:

⇒ Runs from boundaries = 5 × 4 = 20

⇒ Runs from sixes = 9 × 6 = 54

⇒ Runs scored by running = 114 - (20 + 54) = 114 - 74 = 40

⇒ Percentage of runs scored by running = (40 / 114) × 100

⇒ Percentage = (4000 / 114)

⇒ Percentage 35$\frac{5}{57}$

The percentage of his total score made by running between the wickets is 35$\frac{5}{57}$.

Given:

One-third of one-fourth of one-fifth of a number = 18.

Formula Used:

Let the number be x. Then, (1/3) × (1/4) × (1/5) × x = 18.

We need to find three-tenth (3/10) of that number.

Calculation:

⇒ (1/3) × (1/4) × (1/5) × x = 18

⇒ x / (3 × 4 × 5) = 18

⇒ x / 60 = 18

⇒ x = 18 × 60

⇒ x = 1080

Now, three-tenth of that number:

⇒ (3/10) × x = (3/10) × 1080

⇒ 3 × 108 = 324

The value of three-tenth of the number is 324.

Given:

Time taken by A to complete the work = 10 days

Time taken by B to complete the work = 12 days

Time taken by C to complete the work = 15 days

B is assisted by A and C alternately.

Formula Used:

Work done per day = 1 / Time taken

Total work = LCM of individual times

Work done in alternating days = Work of B + Work of (A or C)

Calculation:

⇒ LCM of 10, 12, and 15 = 60 (Total work)

⇒ Work done by A in 1 day = 60 / 10 = 6 units

⇒ Work done by B in 1 day = 60 / 12 = 5 units

⇒ Work done by C in 1 day = 60 / 15 = 4 units

On 1st day: B works with A.

⇒ Total work done in 1st day = 5 + 6 = 11 units

On 2nd day: B works with C.

⇒ Total work done in 2nd day = 5 + 4 = 9 units

Work done in 2 days = 11 + 9 = 20 units

Total work = 60 units

⇒ Total number of such 2-day cycles = 60 / 20 = 3 cycles

⇒ Total time = 3 × 2 = 6 days

Thus, B can complete the work in 6 days when assisted by A and C alternately.

The correct answer is 6 days.

Given:

Profit = 20%

Formula used:

Profit% = [(S.P. - C.P.) ÷ C.P.] × 100

Calculations:

Let the cost price = x

So, Selling price = x + 20% of x = 1.2x

If both C.P. and S.P. are decreased by ₹50, then new profit = 25%

New C.P. = x - 50

New S.P. = 1.2x - 50

⇒ (1.2x - 50) - (x - 50) = 25% of (x - 50)

⇒ 0.2x = 0.25(x - 50)

⇒ 0.2x = 0.25x - 12.5

⇒ 0.25x - 0.2x = 12.5

⇒ 0.05x = 12.5

⇒ x = 12.5 ÷ 0.05

⇒ x = 250

∴ The original cost price of the fan is ₹250.

Given:

4/5 ÷ 3/10 of 4/9 − 4/5 × 1$\frac{1}{9}$ ÷ 8/15 − 3/4 + 3/4 ÷ 1/2

Formula Used:

of = × , a/b ÷ c/d = a/b × d/c

Calculation:

⇒ 4/5 ÷ (3/10 × 4/9) = 4/5 ÷ 2/15 = 4/5 × 15/2 = 6

⇒ 4/5 × 10/9 = 8/9, ⇒ 8/9 ÷ 8/15 = 5/3

⇒ 3/4 ÷ 1/2 = 3/4 × 2/1 = 3/2

⇒ 6 − 5/3 − 3/4 + 3/2

⇒ 72/12 − 20/12 − 9/12 + 18/12

⇒ 61/12

∴ The correct answer is 61/12.

Given:

For a rectangular box:

Breadth = b

Height = h

Formula Used:

Product of the areas of the 3 adjacent faces meeting at a point = (length × breadth) × (breadth × height) × (length × height)

= (l × b × h)²

Calculation:

⇒ Product of the areas of the 3 adjacent faces = (l × b × h) × (l × b × h)

⇒ Product of the areas of the 3 adjacent faces = (l × b × h)²

The correct answer is (length × breadth × height)².

Given:

Principal (P) = Rs. 8,000

Time (T) = 6 years

Rate of interest (R) = 12 paise per rupee per month

Formula Used:

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

Calculation:

Rate per annum = 12 × 12 = 144% (since 12 paise per rupee per month means 12% per year)

⇒ SI = (8000 × 144 × 6) / 100

⇒ SI = 8000 × 864 / 100

⇒ SI = Rs. 5760

The simple interest is Rs. 5760.

Given:

Radha scored 20% of marks and failed by 10 marks.

Seeta scored 30% of marks, which is 20 marks more than the pass mark.

Formula Used:

Total Marks = 100 × (Difference between percentage scores) / (Difference between marks)

Calculation:

Radha's marks = 20% of total marks = 0.2 × Total Marks.

Seeta's marks = 30% of total marks = 0.3 × Total Marks.

Pass marks = Radha's marks + 10 = Seeta's marks - 20.

⇒ 0.2 × Total Marks + 10 = 0.3 × Total Marks - 20.

⇒ 0.3 × Total Marks - 0.2 × Total Marks = 30.

⇒ 0.1 × Total Marks = 30.

⇒ Total Marks = 30 / 0.1.

⇒ Total Marks = 300.

The total marks of the examination are 300.

Given:

Principal (P) = 18000

Rate (R) = 10% per annum = 10/2 = 5% per half year

Formula Used:

Amount = P × (1 + R/100)ⁿ

Calculation:

⇒ Amount = 18000 × (1 + 5/100)³

⇒ 18000 × (1.05)³

⇒ 18000 × 1.157625

⇒ 20837.25

Total Amount = Rs. 20,837.25

Given:

Final Sale Price = 19844

First discount = 12% ⇒ Remaining price = 88% = 0.88

Second discount = 18% ⇒ Remaining price = 82% = 0.82

Formula Used:

Sale Price = Marked Price × 0.88 × 0.82

Calculation:

⇒ 19844 = MP × 0.88 × 0.82

⇒ 19844 = MP × 0.7216

⇒ MP = 19844 ÷ 0.7216

⇒ MP = 27500

Marked Price = ₹ 27,500

Given:

Numbers: 397, 435, 5420

Calculation:

⇒ Numbers after subtracting remainders:

397 - 6 = 391

435 - 10 = 425

5420 - 14 = 5406

⇒ Find HCF of 391, 425, and 5406:

Find the prime factorization:

391 = 17 × 23

425 = 5² × 17

5406 = 2 × 3 × 17 × 53

Common factor is 17.

⇒ HCF = 17

The greatest number that will divide 397, 435, and 5420 leaving remainders 6, 10, and 14 respectively is 17.

Given:

When folded into two equal halves, the perimeter of each part is:

1. 36 cm when folded along one set of sides.
2. 45 cm when folded along the other set of sides.

Formula Used:

Perimeter of a rectangle = 2 × (length + breadth).

Area of a rectangle = length × breadth.

Calculation:

Original sheet dimensions = a and b

Fold along side a: New dimensions = a/2 and b

Perimeter = 36 cm

⇒ 2(b + a/2) = 36

Fold along side b: New dimensions = a and b/2

Perimeter = 45 cm

⇒ 2(a + b/2) = 45

⇒ b + a/2 = 18

⇒ a + b/2 = 22.5

⇒ b = 18 − a/2

⇒ a + (18 − a/2)/2 = 22.5

⇒ a + 9 − a/4 = 22.5

⇒ 3a/4 = 13.5

⇒ a = 18

⇒ b = 18 − 9 = 9

Area = a × b = 18 × 9 = 162 cm²

∴ The correct answer is 162 cm²

Given:

Average age of grandparents = 69 years.

Average age of parents = 39 years.

Average age of grandchildren = 9 years.

Number of grandparents = 2.

Number of parents = 2.

Number of grandchildren = 2.

Formula Used:

Average age of the family = Total age of all family members / Total number of family members

Calculation:

⇒ Total age of grandparents = 69 × 2 = 138

⇒ Total age of parents = 39 × 2 = 78

⇒ Total age of grandchildren = 9 × 2 = 18

⇒ Total age of all family members = 138 + 78 + 18 = 234

⇒ Total number of family members = 2 + 2 + 2 = 6

⇒ Average age of the family = 234 / 6

⇒ Average age = 39 years

The average age of the family is 39 years.
