Question Discussion & Solution

Given ten digit number is 6438123953

First half of the digits are : 64381

These are rearranged in descending order, so it becomes, 86431

Second half of the digits are : 23953

These are rearranged in ascending order, so it becomes, 23359

The new number is 8643123359

Comparing the new number with the given number

We see that, 4 digits position (highlighted) remains unchanged

Hence ‘4’ is the correct answer.

Statement 1 say The price of Jiosimcard(J) is more than Airtelsim card(A).

It means J > A

Now Statement 2 say The price of Airtelsimcard(A) is less than idea sim card(I).

T means I > A

From both statement we can say that the price of Airtelsim card is less from both the sim card

Explanation:

• Parenchyma, Sclerenchyma, and Collenchyma are the Simple Permanent Plant tissues.
• Xylem and Phloem are the Complex Permanent Plant tissue.
• Sclerenchyma: supporting tissue in higher plants.
• Parenchyma: makes up most of the cells within leaves, flowers, and fruits.
• Collenchyma: provides support, structure, tensile strength, and flexibility which helps the plant to bend.
• Xylem:
  • It is plant tissue that transports food water and other dissolved minerals from roots to other parts of the plant.
• Phloem:
  • The main function of the phloem is to transport food materials from the leaf to other parts of the plant.

A keyboard is for putting information including letters, words, and numbers into the computer. A keyboard's primary function is to act as an input device. Using a keyboard, a person can type a document, use keystroke shortcuts, access menus, play games and perform a variety of other tasks.

Key Points

• A modifier key is a key on a computer's keyboard that's only used in conjunction with another key.
• Modifier keys are often used with other keys to perform computer keyboard shortcuts and other commands.
• For example, in many text editor programs pressing the Ctrl+A selects all text.

Additional Information

• The function keys or F keys are lined across the top of the keyboard and labeled F1 through F12. These keys act as shortcuts, performing certain functions, like saving files, printing data, or refreshing a page.
  • For example, the F1 key is often used as the default help key in many programs. The F5 key is used in an Internet browser to refresh or reload a web page. The function of these keys can differ by the operating system and by a software program.
• A special key or media key, or multimedia key is a keyboard key that performs a special function not included with the traditional 104-key keyboard.
  • For example, the picture shows a Logitech keyboard.
• An ergonomic keyboard is a keyboard designed for comfort, ease of use, and reduced strain on the user.
  • Such keyboards may include features like concave or tapered keys, keys that are well-spaced, or keys that separate and angle out from a central pivot point.

Therefore, based on the above information The keys of a keyboard, which are used to modify the input of other keys, are called modifier keys.

Concept:

​Simple Pendulum:

• A simple pendulum consists of a small metallic ball or a piece of stone suspended from a rigid stand by a thread.
  The metallic ball is called Bob.
• A pendulum swings from one extreme position to another and comes back to the same position, this completes one oscillation. 
• One oscillation can also be defined as the pendulum starting from the mean position, going to one extreme, and coming back to the same mean position. 
• The time duration to compete for one oscillation is called time period and the is reciprocal of time period is frequency. 
• Frequency: The number of oscillations per unit time is called frequency. 

\(frequncy =\frac{Oscillation}{Time}\)

Calculation:

Given that : Frequency = 2 hz and time = 16 sec.

In a sec pendulum completes 2 oscillations per second.

⇒ Oscillations = Frequency × time

⇒ Oscillations = 2×16

⇒ Oscillations = 32

Additional Information

The time period of a simple pendulum depends upon on the length of the string and acceleration due to gravity.

\(T = 2 \pi \sqrt{\frac{l}{g}}\)

l is length, g is acceleration due to gravity.
