The correct answer is Parasailing.

Key Points

• Parasailing is NOT covered under the National Air Sports Policy 2022.
• The National Air Sports Policy 2022 is a policy document that outlines the guidelines and regulations for air sports activities in India.
• Parasailing is not considered an air sports activity as it involves being towed by a boat while attached to a parachute, rather than flying in an aircraft.

Additional Information

• Aerobatics, Gliding, and Ballooning are all covered under the National Air Sports Policy 2022.
• Aerobatics is a type of aerial performance that involves complex and precise maneuvers in an aircraft.
• Gliding is a type of air sports activity that involves flying in a glider, which is an unpowered aircraft.
• Ballooning is a type of air sports activity that involves flying in a hot air balloon.

Given: Seven persons N, O, P, Q, R, S, and T are sitting in a row facing North.

1. Exactly two people are sitting to the right of T who is sitting to the immediate right of Q. 

2) Only three persons are sitting between P and T. 

3) N is sitting at one end. 

4) P is sitting somewhere to the left of N.

5) O is to the immediate right of P and immediate left of R.

And, S will sit on the remaining place.

So, 'Q' is sitting in the middle.

Hence, the correct answer is "Option 3".

According to the given Venn diagram:

The shaded area shows the "total number of graduated skilled workers are NOT contractual".

So, the total number of graduated skilled workers are NOT contractual = 27.

Hence, the correct answer is "Option 2".

The logic followed here is:

'AFPQV' is written as 'CITVB',

‘DLNPG' is written as 'FORUM’

Similarly, for 'LNAGK'

So, 'LNAGK' will be written as 'NQELQ'.

Hence, the correct answer is "Option 3".

Shortcut Trick

Side of one cube = ³√216 = 6 cm.

When 5 cubes are joined, Length (L) = 5 × 6 = 30 cm, Breadth (B) = 6 cm, Height (H) = 6 cm.

Lateral Surface Area = 2 × (L + B) × H

⇒ 2 × (30 + 6) × 6 = 2 × 36 × 6 = 432 cm².

∴ The correct answer is 432 cm².

Alternate Method

Given:

Volume of one cube = 216 cm³

Number of cubes = 5

Formula Used:

Volume of cube = a³

Lateral Surface Area (LSA) of cuboid = 2h(l + b)

Calculations:

⇒ a³ = 216

⇒ a = √³(216) = 6 cm

⇒ New length (l) = 5 × a = 5 × 6 = 30 cm

⇒ Breadth (b) = 6 cm and Height (h) = 6 cm

⇒ LSA = 2 × 6 × (30 + 6)

⇒ LSA = 12 × 36

⇒ LSA = 432 cm²

∴ The correct answer is 432 cm².

Additional Information

Total Surface Area of Cuboid

It includes the top and bottom faces: TSA = 2(lb + bh + hl).

Lateral Surface Area vs Total Surface Area

Lateral area excludes top and bottom bases. For a cube, LSA = 4a² and TSA = 6a².

Diagonal of Cuboid

The longest rod that can be placed inside is given by √(l² + b² + h²).

The correct answer is Sphygmomanometer.

Key Points

• Sphygmomanometer is used to measure blood pressure.
• Sphygmomanometer consists of an inflatable cuff to collapse and then release the artery under the cuff in a controlled manner, and a mercury or aneroid manometer to measure the pressure.
• Blood pressure is measured in millimeters of mercury (mmHg) and is expressed as two numbers: systolic pressure (the higher number) and diastolic pressure (the lower number).

Additional Information

• Spectrophotometer is an instrument used to measure the amount of light absorbed by a substance at different wavelengths.
• It is commonly used in chemistry and biology to analyze the properties of substances.
• Urinometer is an instrument used to measure the specific gravity of urine, which is a measure of the concentration of dissolved substances in urine.
• Haemoglobin meter is an instrument used to measure the amount of haemoglobin in blood.
• It is an important parameter in the diagnosis and monitoring of anaemia and other blood disorders.

Given:

Mr. Amardeep started his drive from his office and drove for 8 km towards the south.

Then he took a left turn and drove for 15 km to reach city centre.

Then he turned 90° in the anti-clockwise direction and drove for 8 km to reach the city palace.

From the city palace, he took a left turn and drove for 8 km to reach his home.

So, Amardeep's office is at the 'North-west' direction from the City centre,

And his Office is in the 'West' direction from his Home.

Hence, the correct answer is "Option 4".

Calculation

The sum of the marks scored by A in Mathematics and B in Hindi = 90 + 80 = 170

The sum of the marks scored by C in Science and D in English = 76 + 64 = 140

The ratio = 170: 140 = 17: 14

The answer is 17: 14

The correct answer is Collecting non-timber forest produce.

Key Points

• Non-timber forest produce (NTFP) refers to goods and services that are obtained from forests other than timber.
• These include fruits, nuts, honey, medicinal plants, and other resources that can be harvested sustainably without damaging the forest ecosystem.
• Collecting NTFP can provide livelihoods for local communities and reduce their dependence on unsustainable activities such as logging and poaching.
• This can help to conserve forests and wildlife in the long term.
• Unlike other activities such as building roads and dams, collecting NTFP does not require major infrastructure development that can have negative impacts on the environment and local communities.

Additional Information

• Using forests as a source of raw material for industries can lead to overexploitation of forest resources and contribute to climate change through emissions from processing and transportation of wood products.
• Converting forests to plantations, especially monoculture plantations, can have negative impacts on biodiversity, soil fertility, water availability, and local livelihoods.
• Agroforestry and mixed-species plantations can be more sustainable alternatives.
• Building roads and dams in forested areas can fragment habitats, facilitate illegal activities such as hunting and logging, and displace local communities.
• Proper environmental impact assessments and community consultations are necessary to minimize these impacts.

Calculation

⇒ 23 × 32 × 7 = 8 × 9 × 7

= 504

The answer is 504.
