Checking Statement I:

Akhil > Chetan > Ekta/Bina

But we don't know whether Dinesh or Chetan is the second tallest.

Hence data in statement I is not sufficient to answer the question.

Checking Statement II:

Akhil > Dinesh/Chetan> Dinesh/Chetan > Bina > Ekta

But we don't know whether either Dinesh or Chetan is the second tallest.

Hence data in statement II is not sufficient to answer the question.

Checking both statements I and II:

Akhil > Dinesh/Chetan> Dinesh/Chetan > Bina > Ekta

Still, we cannot determine the second tallest person.

Hence data in both statements I and II is not sufficient to answer the question.

Hence, Option D is correct.

International Yoga Day is celebrated on 21^st June every year.

Similarly;

Kargil Victory day is commemorated on 26^th July every year.

Common Explanation:
References:
Exactly two persons are sitting between P and Q.
Only one person is sitting between P and U.
Inferences:
From the above references, we get two different cases:

References:
S is sitting second to the right of R.
Inferences:
From the above reference, we get the following arrangements:

References:
T is not sitting beside S.
Inferences:
So, from this case 2 will be eliminated as T is not sitting beside S.
Hence, we get our final arrangement:

The family chart is as follows:

i) A is brother of B

The middle digit of first term becomes power to the next term.

The logic follows here is:

In fig 1:

12 = 6 ÷ 2 × 4

12 = 3 × 4 

12 = 12

In fig 2:

80 = 20 ÷ 2 × 8

80 = 10 × 8

80 = 80

Similarly,

63 = ? ÷ 2 × 21

63 / 21 = ? ÷ 2

3 = ? ÷ 2

? = 3 × 2

? = 6

Hence, the correct answer is "6".

Checking → statement I:

References:

Point A is 3km north of library.

Point C is 3km North of Point B.

Point D is 3km East of point C.

Inferences:

From the above references, we can conclude that instruction about college is missing in statement I.

So, we can’t determine the direction between library and college.

Thus, statement I alone is not sufficient to answer the question

Checking → Statement II:

References:

College is 7km North of point F.

Point D is 6km North of point E.

Library is 7km west of point E.

Point F is 4km East of point E.

Inferences:

From the above references, we can conclude the following.

We can conclude that library is to the South West direction with respect to college.

Thus, statement II alone is sufficient to answer the question.

Hence, option B is correct.

Given:

x + y + 1 = 0

Concept Used:

(a + b )³ = a³ + b³ + 3ab (a + b)

Calculations:

x + y + 1 = 0

⇒ x + y = -1

Cubing on both sides we get

(x + y)³ = ( -1 )³

⇒ x³ + y³ + 3xy( x + y ) = -1

⇒ x³ + y³ + 3xy ( -1) = -1

∵ x + y = -1

⇒ x³ + y³ - 3xy = -1

∴ required value = -1

There are four different types of calculation operators in excel: arithmetic, comparison, text concatenation, and reference.

To perform basic mathematical operations such as addition, subtraction, or multiplication-or to combine numbers-and produce numeric results the arithmetic operators are used.

When two values are compared by using comparison operators (=, <, >, …), the result is a logical value either TRUE or FALSE.

The ampersand (&) is used to join, or concatenate, one or more text strings to produce a single piece of text.

The reference operator (colon, comma, space) combine ranges of cells for calculations.

The correct answer is Malware.

Key Points

• Malware, short for malicious software, is a blanket term for viruses, worms, trojans and other harmful computer programs hackers use to wreak destruction and gain access to sensitive information.
• Malicious Software refers to any malicious program that causes harm to a computer system or network. Malicious Malware Software attacks a computer or network in the form of viruses, worms, trojans, spyware, adware or rootkits.
• There are a number of different ways of categorizing malware:
  • A Worm is a standalone piece of malicious software that reproduces itself and spreads from computer to computer.
  • A Virus is a piece of computer code that inserts itself within the code of another standalone program, then forces that program to take malicious action and spread itself.
  • A trojan is a program that cannot reproduce itself but masquerades as something the user wants and tricks them into activating it so it can do its damage and spread.

The correct answer is Auto Sum

Important Points

• The symbol "Ʃ" indicates the auto sum in MS Excel.
  • “Ʃ” is a Greek character called Sigma
  • Excel automatically enters a formula to sum the numbers while using the Auto sum.
  • The AutoSum button is available in the 'Home' tab on the excel ribbon.
  • It is also available in the 'Formulas' tab on the excel ribbon.

Key Points

• The Autosum Excel function can be accessed by typing ALT +  = sign in a spreadsheet, and it will automatically create a formula to sum all the numbers in a continuous range. It allows you to easily add up a series of numbers either vertically or horizontally without having to use the mouse or even the arrow keys on the keyboard.
• The Autosum Excel shortcut is very simple – just type two keys: ALT =
  • Step 1: Place the cursor below the column of numbers you want to sum (or to the left of the row of numbers you want to sum).
  • Step 2: hold down the Alt key and then press the equals = sign while still holding Alt.
  • Step 3: press Enter.

Additional Information

• The symbol ">=" indicates the 'Greater than or equal to' in MS Excel.
• The symbol "<=" indicates the 'Less than or equal to' in MS Excel.
• The symbol "<>" indicates 'Not equal to' in MS Excel.

• The print option is available under the file menu or the office button option available at the left top corner of the screen in a document. Alternatively, you can go to the document that you wish to print and right-click ( using your mouse) it.
• All: The whole document will be printed.
• Current Page: Only the page where the cursor is currently located will be printed.
• Selection: Only the text highlighted on the screen will be printed. The printed copy of this text may well be wrapped differently from what is on screen.
• Print Page Number(s): Only the pages you specify will be printed. Specify pages by typing one or more page numbers as they appear on the pages of your document. You may specify a range of characters by using a hyphen. You may also specify one or more sets of pages by using a comma. For example, to print pages ix, x, 15, 16, and 17, you might type ix-x,15-17
• Page Sequence Number(s): Only the pages you specify will be printed, but you must specify those pages as if your document starts at page 1 and continues with pages 2, 3, etc. In other words, you may have to ignore the page numbers displayed on each page and simply count pages in the document or look at the status line when the cursor is on each page you wish to specify. This option is useful when one or more page numbers are repeated (e.g. you have two pages that are labeled "1"). You may use the hyphen and comma characters as described above.

The correct option is (3) 10

Given formula:

=Min(10, 20, 30, 40, 50)

Calculation:

the least number among a group of values is returned.

Hence the min of the given excel formula = 10

Key Points

The syntax of it is as follows:

Number 1, Number 2, Number...

• The sequence of values from which you wish to get a minimum is number1, [number2],... Number 1 must be entered, however [number2] and the remaining items are optional.
• In a single function, 255 arguments are permitted. Numbers, cells, reference arrays, and ranges are all acceptable types of parameters. Arguments like logical values, text, and empty cells are, however, disregarded.

Additional Information

• The MIN function in Excel is a built-in function that locates the lowest value inside a range.
• Text-filled cells are ignored by the function. Only cells with numbers will function properly. In contrast to MIN, another function named MAX finds the largest value inside a range.

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.
