BODMAS Table

Given equation : 84 * 6 * 25 * 13 * 3

Option 1) ÷, +, =, × by subsituting these value according to BODMAS table we get

84 ÷ 6 + 25 = 13 × 3

14 + 25 = 13 × 3

14 + 25 = 39

39 = 39(LHS = RHS)

Option 2) =, -, +, ×

84 = 6 - 25 + 13 × 3

84 = 6 - 25 + 39

84 = 45 - 25

84 ≠ 20(LHS ≠ RHS)

Option 3) +, ÷, =, ×

84 + 6 ÷ 25 = 13 × 3

84 + 0.24 = 13 × 3

84 + 0.24 = 39

84.24 ≠ 39(LHS ≠ RHS)

Option 4) -, -, =, +

84 - 6 - 25 = 13 + 3

84 - 6 - 25 = 16

84 - 31 = 16

53 ≠ 16(LHS ≠ RHS)

Hence, "÷, +, =, ×" is the correct answer.

The pattern followed here is:

Logic: @ Replace with + and # is replace with -

1) 13 @ 2 # 5 = 10

= 13 + 2 - 5

= 15 - 5 = 10

And,

2) 43 # 9 @ 16 = 50

= 43 - 9 + 16

= 59 - 9 = 50

Similarly,

3) 8 @ 6 # 3 = ?

= 8 + 6 - 3

= 14 - 3 = 11

Hence, the correct answer is "11".

The correct Answer Option 3: 3

Explanation:

• Planning or Cloud Readiness Assessment: This phase involves determining whether a business or system is ready to move to the cloud. It involves evaluating the existing infrastructure, applications, and data to see how they might be migrated. This phase often includes a cost-benefit analysis to evaluate whether moving to the cloud is financially advantageous.
• Migration or Implementation: This phase involves the actual process of moving data, applications, and other business elements to the cloud. It requires careful planning to minimize downtime and data loss. The process can range from rehosting (simply moving an application from on-site servers to cloud servers without modifications) to refactoring (rethinking and reworking the application to take advantage of cloud-native features).
• Management and Optimization: After the migration, the systems now in the cloud need to be managed. This includes ensuring that they are running smoothly, scaling resources up and down as necessary, and continually optimizing to reduce costs and improve performance.

The option that is not a key feature of internal memory is: No storage
Explanation: Internal memory, also known as main memory or primary storage, is a fundamental component of a computer system that provides fast, temporary storage and retrieval of data.Additional Information

• Fast access: Internal memory allows the processor to access data and instructions rapidly. This is crucial for the performance of the system because the speed of the processor is typically much higher than that of external storage devices.
• Limited storage capacity: While internal memory is faster, it's also much more expensive than external storage. As a result, it's generally limited in capacity. This is why we rely on external storage devices (like hard drives or SSDs) for storing large amounts of data over the long term.
• No storage: This option is incorrect. Internal memory does provide storage -- in fact, that's one of its primary functions. It's used for storing data and instructions that are being actively used or processed by the CPU.
• Temporary storage: The data in internal memory (like RAM) is temporary. When the power is turned off, any data in this memory is lost. This is why it's crucial to save important data to a more permanent form of storage, like a hard drive.

The correct option is (2)

Hard disk

Key Points

• Hard disc platters are separated into a number of concentric tracks. Each track has a number of sectors that can individually hold the same amount of data.
• The smallest physical storage unit on a disc is called a sector, and on most file systems, it has a fixed size of 512 bytes.
• Data is kept on hard drives in tiny, concentrically spaced bands. A drive head can read or write data on a track, which is a circular band or ring, while it is in one position. A 3.5-inch hard drive has a maximum track count of over a thousand. Each track's sectors are its sections.
• A track on a magnetic disc or optical disc is divided into sectors for computer disc storage. Hard disc drives (HDDs) and CD-ROMs and DVD-ROMs typically store 512 bytes and 2048 bytes of user-accessible data, respectively, in each sector.

Additional Information

• Random-access memory (RAM) that uses latching circuitry (flip-flops) to store each bit is known as static random-access memory (static RAM or SRAM).
• The data or program code required by a computer processor to function is often stored in dynamic random access memory (DRAM), a type of semiconductor memory.
• A storage device that uses magnetic tape as a medium for storing is called a magnetic tape drive. It makes use of a lengthy, thin plastic film strip with tapes that are thinly coated with magnetism.

Number of proton = 7
Number of proton + Number of neutron = 15
Number of neutron = 15 - 7 = 8

For ₈O¹⁶
Number of proton = 8
Number of proton + Number of neutron = 16
Number of neutron = 16 - 8 = 8

Thus, both have same number of neutrons, is the correct set of isotones.

Concept-

• Hepatitis is a liver disease that is caused due to viral infection. In this condition, there is swelling in the liver.
• There are five types of viruses in hepatitis, such as A, B, C, D, and E.
• There is a need to worry more about these five types because of them only epidemic-like condition is happening and the population of death is increasing.

Important Points

• Hepatitis A is a liver disease caused by the hepatitis A virus. People get affected by the virus when they are unhygienic and eventually come in contact with the food or water of an infected person.
• The disease is caused by exposure to contaminated water or food, improper sanitation and poor personal hygiene.
• Unlike in the case of hepatitis B and C, hepatitis A infection does not lead to chronic liver disease and is rarely fatal. However, it can cause debilitating symptoms and fulminant hepatitis, which is fatal.

Additional Information

• Its root cause is due to hepatitis A, hepatitis B, or hepatitis C virus.
• Sometimes the body's immune cells detect that liver cells are being damaged.
• Alcohol is metabolized directly by the liver, due to which it also circulates in other parts of the body. Therefore, there is a risk of hepatitis by consuming excessive amounts of alcohol.

The correct answer is conservation of linear momentum.

Key Points

• The Jet engine works on the phenomenon of Conservation of Linear Momentum.
  • It produces a large volume of gases through the combustion of fuel, which is allowed to escape in a backward direction through a jet.
  • The backward rushing gas gains large momentum because of high velocity.
  • It thus imparts an equal and opposite momentum to the jet engine.
  • The jet engine, thus, moves forward at high speed.

Additional Information

• Momentum: Momentum is the product of the mass and the velocity of an object or particle. It is a vector quantity.
  • The standard unit of momentum magnitude is the kilogram-meter per second (kg·m/s).
    • P = m v
    • Where P = momentum, m = mass of the body, and v = velocity of the body.
• Conservation of Linear Momentum: Conservation of Linear Momentum states that a body in motion retains its total momentum (product of mass and vector velocity) unless an external force is applied to it.
