Ground-level ozone is formed when nitrogen oxides (NOx) and volatile organic compounds (VOCs) react in sunlight. Among human-made sources, vehicle emissions are the largest contributor, as they release significant amounts of NOx and VOCs from fuel combustion.

While industrial emissions and biomass burning also contribute, transportation sources—especially cars, trucks, and buses—are the dominant cause in urban areas. Natural sources (like wildfires or vegetation) play a role but are not the primary driver of ozone pollution in most cases.

 

South Africa is one of the main producers of manganese in the world. Its manganese reserves are found in regions such as the Cape Province, including Krugersdorp and Postmasburg. Manganese is a vital resource used in various industries, including steel production and battery manufacturing.

81% of 600 – x = 40% of 300
486 – x = 120
x = 366
Hence, Option C is correct.

The ratio of 1.5 m to 10 cm is:

• To compare lengths, we should convert both lengths to the same unit. Let's convert 1.5 m to cm (since 1 m = 100 cm).
• 1.5m=1.5 x 100 cm =150 cm
• 1.5m=1.5x100cm =150cm.
• Now we have 150 cm to 10 cm. The ratio is 150:10
• To simplify, divide both by their greatest common divisor, which is 10.
• 
• So, the ratio is 15 : 1, which corresponds to option (d).

Let the numerator = x and denominator = y

y + 3 = 2y ⇒ y = 3

x +1= 3 ⇒ x = 2

∴ xy = 2 × 3 = 6

Using Rule 1 :
1st number × 2nd number = L.C. M. × H.C.F,
We have,
First number × second number = LCM × HCF

–12, –6, 0, 6,…
Let a(1) = -12, a(2) = -6, a(3) = 0, a(4) = 6
First relational d,
a(2) – a(1) = -6 – (-12) = 6
Second relational d,
a(3) – a(2) = 0 – (-6) = 6
Third relational d,
a(4) – a(3) = 6 – (0) = 6
all the d are equals to each other, hence
d = 6.

Hence, Option B is correct.

Checking Statement I:

Using the above references, we get the following arrangement:

Kamal > Rohit > Priya/Johny > Suresh > Tinku

Clearly Kamal is the oldest among all.

Hence data in statement I is sufficient to answer the question.

Checking Statement II:

Using the above references, we get the following arrangement

Kamal > Priya > Suresh > Johny > Tinku > Rohit

Clearly Kamal is the oldest among all.

Hence data in statement II is sufficient to answer the question.

Here, the data in either Statement I or II alone is sufficient to answer the question.

Hence, Option C is correct.

As President is the nominal head of a country, similarly Governer is the nominal head of a State.

These are all the languages of computer.

From the common explanation, we get Rahul > 87, so only 90 is greater than 87.

Hence, Option C is correct.

References:

Tarun scored more marks than Priyam but less than Rahul.

Sagar neither scored 3rd highest nor scored lowest marks.

Priyam scored more marks than Anurag.

Sagar scored less than Tarun, who scored 87 marks.

Inferences:

From the above references, we get the following arrangements

Rahul > Tarun (87) > Priyam > Sagar > Anurag

As the young one of a 'cat' is 'kitten' in the same way the young one of 'woman' is 'baby'.

The hardware options given are:
A: Magnetic tape
B: Printer
C: VDU terminal
D: Assembler
To determine which option is not a hardware, we need to understand the definition of hardware. Hardware refers to the physical components of a computer system or any electronic device. It includes devices that can be seen and touched.
Explanation:
To determine the correct answer, we can analyze each option:
A: Magnetic tape - This is a physical storage medium used to store data.
B: Printer - This is a hardware device that produces hard copies of documents or images.
C: VDU terminal - VDU stands for Video Display Unit. It is a hardware device that displays visual output from a computer.
D: Assembler - Assembler is not a hardware device. It is a software program used to convert assembly language into machine code.
Conclusion:
Based on the analysis, the option that is not a hardware device is D: Assembler. Assembler is a software program, not a physical component of a computer system.

FTP can be run on the following operating systems:
- Unix: FTP can be run on Unix operating systems. Unix is a family of multitasking, multiuser computer operating systems that are widely used for servers and workstations.
- Linux: FTP can be run on Linux operating systems. Linux is an open-source operating system that is based on the Unix operating system.
- Dos/Windows: FTP can be run on Dos/Windows operating systems. DOS (Disk Operating System) is an operating system that was popular in the early days of personal computers, while Windows is a widely used operating system developed by Microsoft.
Therefore, the correct answer is option B: Linux, as FTP can be run on Linux operating systems. However, it is important to note that FTP can also be run on Unix and Dos/Windows operating systems, so option D is also correct.
Overall, FTP is a versatile protocol that can be run on various operating systems, allowing users to transfer files between computers over a network.

Explanation:
In real-time operating systems (RTOS), the response time is very critical. Here is a detailed explanation:
Real-time Operating System (RTOS):
- An operating system designed for systems that require precise and predictable response times.
- It is used in applications such as industrial control systems, aerospace systems, medical devices, etc.
Response Time:
- The time it takes for a system to respond to a request or event.
- In real-time operating systems, the response time needs to be very fast and predictable.
Importance of Response Time:
- In certain applications, such as control systems or critical medical devices, even a small delay in response time can have serious consequences.
- Real-time operating systems are designed to ensure that the response time is as fast and predictable as possible.
Comparison with other Operating Systems:
- Multitasking Operating System: In multitasking operating systems, response time is important, but not as critical as in real-time operating systems. These operating systems prioritize multiple tasks and allocate resources accordingly.
- Batch Operating System: In batch operating systems, response time is not critical as the system processes a batch of tasks without any user interaction.
- Online Operating System: In online operating systems, response time is important, but not as critical as in real-time operating systems. These operating systems prioritize online user interactions but may not guarantee precise response times.
Conclusion:
- In real-time operating systems, the response time is very critical due to the nature of applications that require precise and predictable response times.
- Real-time operating systems are designed to prioritize and optimize response times to ensure fast and predictable system behavior.
