Given:

I. x² - 27x + 182 = 0

II. y² – 28y + 196 = 0

Calculation:

I. x² - 27x + 182 = 0

⇒ x² – 13x – 14x + 182 = 0

⇒ x(x – 13) – 14(x – 14)= 0

⇒ (x – 13)(x – 14) = 0

⇒ x = 13, 14

II. y² – 28y + 196 = 0

⇒ y² – 14y – 14y + 196 = 0

⇒ y(y – 14) – 14(y – 14) =0

⇒ (y – 14)(y – 14) = 0

⇒ y = 14, 14

When we compared the values of ‘x’ and ‘y’ in the table above, we found that there are TWO relations between X and Y i.e. < and =. So, a relation between x and y is “x ≤ y”.

∴ After comparison, for all the values of x and y the relation is “x ≤ y”.

Calculations:

From I,

6x² + (1/2) = (7/2)x

⇒ 12x² - 7x+ 1 = 0

⇒ 12x² - 4x - 3x + 1 = 0

⇒ 4x(3x - 1) - 1(3x - 1) = 0

⇒ (4x - 1)(3x - 1) = 0

Taking,

⇒ 3x - 1 = 0 or 4x - 1 = 0

⇒ x = 1/3 or x = 1/4

From II,

12y² + 2 = 10y

⇒ 12y² - 10y + 2 = 0

⇒ 12y² - 6y - 4y + 2 = 0

⇒ 6y(2y - 1) - 2(2y - 1) = 0

Taking,

⇒ 2y - 1 = 0 or 6y - 2 = 0

⇒ y = 1/2 or y = 1/3

Comparison between x and y (via Tabulation):

​∴ x ≤ y.

Calculation:

Let x be the total number of population

Total number of population = (21/100)x – (15/100)x = 2184

⇒ (6/100)x = 2184

⇒ x = (218400/6) = 36400

Let y be the total male population

Total male population = (24/100)y – (18/100)y = 936

⇒ (6/100)y = 936

⇒ y = (93600/6) = 15600

Total number of female population in town C and D = 3900 + 3328 = 7228

∴ The total number of female population in town C and D is 7228.

Calculation:

Let x be the total population

Total number of population = (21/100)x – (15/100)x = 2184

⇒ (6/100)x = 2184

⇒ x = (218400/6) = 36400

Let y be the male population

Total number of male population = (24/100)y – (18/100)y = 936

⇒ (6/100)y = 936

⇒ y = (93600/6) = 15600

As per the given table we can deduce that males in town C is the highest

∴ The town in which the number of male is the highest is C.

Calculation:

Let x be the total population

Total number of population = (21/100)x – (15/100)x = 2184

⇒ (6/100)x = 2184

⇒ x = (218400/6) = 36400

Let y be the male population

Total number of male population = (24/100)y – (18/100)y = 936

⇒ (6/100)y = 936

⇒ y = (93600/6) = 15600

The total number of female in all the six towns = 36400 – 15600 = 20800

⇒ Difference between number of females and males = 20800 – 15600 = 5200

⇒ Required difference = (5200/15600) × 100 = 33.33%

∴ Approximate percentage of the total number of females from all the six towns is 33.33% more than that of the males from all the six towns.

Given:

870, 855, 840, 825, 810, 800

Calculation:

The logic follows here is;

870 - 15 = 855

855 - 15 = 840

840 - 15 = 825

825 - 15 = 810

810 - 15 = 795 ≠ 800

There should be 795 instead of 800.

∴ 800 is the wrong term.

Given:

Ram lent Rs.2.7 lakh amount to Pawan and Pooja

Lent money to Pawan and Pooja in ratio of 5 : 4

Pooja payback its amount after 3 years at 10% annual compound interest

Pawan payback its amount after 3 year at 15% annual compound interest

Concept:

A = P × (1 + R/100)^T

A = Final amount

P = Initial amount

R = Rate of interest

T = Time

Calculation:

Lent money to Pawan and Pooja in ratio of 5 : 4

Lent by Pawan = (5/9) × 270000

⇒ Rs.1,50,000

Lent by Pooja = (4/9) × 270000

⇒ Rs.1,20,000

Pawan payback to Ram = 150000 × (1 + 10/100)³

⇒ 150000 × (11/10) × (11/10) × (11/10)

⇒ Rs.1,99,650

Pooja payback to Ram = 120000 × (1 + 15/100)³

⇒ 120000 × (23/20)³

⇒ 120000 × (23/20) × (23/20) × (23/20)

⇒ Rs.1,82,505

Pawan payback to Ram – Pooja payback to Ram = 199650 – 182505

⇒ Rs.17,145

∴ At the end of time duration the amount received by Ram from Pawan was Rs.17145 more than that received from Pooja.

Persons: Azim, Bindu, Chaitra, Delphin, Eza, Fath, and Gayl

Dresses: Jean, Shirt, Kurta, Skirt, Saree, Salwar and Dhoti

Number of dresses: The number of dresses bought by each of them are in the consecutive multiples of 3. The total number of dresses bought by all people cannot exceed 85.

So, 3, 6, 9, 12, 15, 18 and 21 are the number of dresses bought by them.

1. Either Eza or Gayl bought 12 Skirts.

2. Delphin bought a number of Jeans, which is higher than only Fath.

3. So Fath bought 3 dresses and Delphin bought 6 jeans.

4. The number of Sarees bought is twice the number of Shirts bought.

5. Saree is bought for the second highest number. So, number of Saree is 18 and Shirt is 9.

6. Gayl bought twice the number of dresses of Delphin. So, Case 1 is invalid.

6. Chaithra bought the highest number of dresses but neither bought Saree nor Salwar.

So, the number is 21 and the dress left for it is Kurta.

7. Either Shirt or Dhoti is bought for the lowest number.

As Shirt is already 9, so the number of Dhoti bought is 3.

8. The number of Sarees bought is twice the number of Shirts bought, which is not bought by Azim.

So, he bought 15 salwar.

9. Neither Azim nor Bindu bought 18 dresses.

10. Saree is bought for the second highest number. So, number of Saree is 18 and Shirt is 9.

The final arrangement is,

The correct option is (1)

INT

Concept:-

The sum() function calculates the sum of a set of values. MYSQL supports the SQL standard integer types INTEGER (or INT) and SMALLINT. INT in MYSQL is an integer data type, which is a whole number. It allows numbers to be written without fractional parts.

SUM(column), returns the sum of the values for the specified column.

For example, MySQL > SELECT SUM(price) FROM INVENTORY; Output is 4608733.00

Key Points

• Use SQL's SUM method if you need to add a set of numbers to your table. If there are no rows in the result set, NULL is returned. One of the categories of aggregate functions, it.
• Multiple Row Functions is another name for aggregate functions. These functions operate on an entire collection of records and give a single value for each column of the records they affect.
• The string data types are CHAR, VARCHAR, BINARY, VARBINARY, BLOB, TEXT, ENUM, and SET.

c) GROUP BY is used to group the result set by one or more columns.

The GROUP BY clause groups rows based on the values in one or more columns and, typically, is used in combination with aggregate functions to return a single result row for each group.

Additional InformationWHERE clause is used to filter the result set of a SELECT, UPDATE, DELETE statement. It is used to specify a condition that rows have to meet in order to be selected or affected.

ORDER BY is used to sort the result set in a specific order. It is used to sort the result set by one or more columns in ascending or descending order.

The FROM clause is used to specify the table or tables from which to retrieve the data and it is usually one of the first clauses in a SELECT statement.

Statement (a): Overloading a function gives the capability to an existing operator to operate on other data types.

This statement is incorrect. Operator overloading is a type of polymorphism in which an operator is overloaded to give a different meaning or user defined meaning. It allows to change the way an operator can work. It gives the capability to an existing operator to operate on other data types.

Statement (b): Inheritance in object-oriented programming provides support to reusability.

This statement is correct. When a class acquires the properties of another class, this is known as inheritance. The class which acquire the properties and method is known as derived class and other one is parent or base class. Inheritance another name for reusability.

Statement (c): When object of a derived class is defined, first the constructor of derived class is executed then constructor of a base class is executed.

This statement is incorrect Constructor is a special member function of class that is automatically executed or called when objects of that class will be created. As when object of derived class is defined, automatically derived class constructor and base class constructor will execute inside them.

Statement (d): Overloading is a type of polymorphism.

This statement is correct. Operator is a type of polymorphism in which an operator is overloaded to give a different meaning or user defined meaning. It allows to change the way an operator can work.

The correct answer is Cybersecurity.

Key Points

• Cryptography is a specialized area of Cybersecurity.
• Cryptography is also defined as the study of secure communications techniques that allow only the sender and intended recipient of a message to view its contents.
• It covers the obfuscation of information in images using techniques such as microdots or merging.
• It is used to protect written documents.
• The main purpose of cryptography appears to be making content and images undecipherable, the true goal of cryptography in an information technology context is to ensure the confidentiality and integrity of any information technology system.

• Queue is data structure which is First in First Out (FIFO) or Last in Last Out (LILO) which means the element which is inserted first comes out first form the queue or the elements inserted last comes out last from the queue
• Stack is data structure which is Last in First Out (LIFO) or First in Last Out (FILO) which means the element which is popped last from stack is pushed first in stack, or element which is pushed first in stack is popped last from stack

The correct answer is option 3.

Key Points

• A firewall is a security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
• It acts as a barrier between an untrusted network (like the internet) and a trusted network (like a company's internal network) to prevent unauthorized access to the trusted network.
• Firewalls can be either hardware or software-based and are an essential component of network security.

Additional Information

• Hub: It is a network device that connects multiple devices in a network, but it does not provide any security features.
• Router: It is a network device that directs traffic between networks, but it has limited security features compared to a firewall.
• Bridge: It is a network device that connects two network segments, but it also does not provide any security features.

Concept:

If there are two relations A and B with m and n number of tuples respectively. Then maximum number of tuples in their natural join will be m*n. Maximum tuples will be when one attribute will contain all same values as the other relation having same attribute.

Explanation:

Given: two relations R and S having tuples 3 and 2 respectively.

So, their natural join will contain maximum of 3 * 2= 6 tuples.

Example:

Consider table R (a, b) as ;

Relation S(a, c) as :

Here, the natural join of R and S will be :

So, it contains total of 6 tuples.

Concept:

Big data is a field that treats ways to analyse, systematically extract information from, or otherwise deal with data sets that are too large or complex to be dealt with by traditional data-processing application software.

Explanation:

Big Data can be defined using the famous 3 Vs - Volume, Velocity and Variety.

VOLUME:

Volume refers to the amount of data generated through websites, portals and online applications.

VELOCITY:

With Velocity we refer to the speed with which data are being generated.

VARIETY

Variety in Big Data refers to all the structured and unstructured data that has the possibility of getting generated either by humans or by machines.

The most added data are unstructured -texts, tweets, pictures & videos.

The correct answer is option 4.

Concept:

The given data,

preorder = ABCDEF

In order = BADCFE

The binary tree for the traversal is,

Post order for the above tree is,

BDFECA

Hence the correct answer is BDFECA.

Layer 2 Ethernet Frame Format:

Cyclic Redundancy codes is an error detection mechanism used in the data link layer. It is based on binary division. Cyclic redundancy check bits are appended to the end of data unit so that the resulting data unit becomes exactly divisible by a second, predetermined binary number. At the destination, the incoming data unit is divided by the same number. If at this step there is no remainder, the data unit is assumed to be correct and is therefore accepted. A remainder indicates that the data unit has been damaged in transit and therefore rejected.
