Arithmetic
To calculate the arithmetic mean, you can add up all the values and divide them by the number of items.for the calculation you need the value of sales everyday add them and then divide it by 7 if sunday is included in it or the working days of the week in which sales are done.
Generally average or arithmetic mean Is based on all the observations which is easy and simple to comprehend and calculation

Question:
Select the most appropriate option to fill in the blank number 5.
Option 1: alert
Option 2: fit
Option 3: ready
Option 4: fixed
Correct Answer: ready
Solution : The correct choice is the third option.
In the context of the passage, the word ready fits best to describe the state Swaminathan needs to achieve for school, as it means to be prepared or organised for a particular purpose or action.

Select the most appropriate option to fill in the blank number 3.
Option 1: disputes
Option 2: puzzles
Option 3: debates
Option 4: conditions
Correct Answer: puzzles
Solution : The correct choice is the second option.
In the context of the passage, the word "puzzles" fits best to describe the five tasks in profit and loss under arithmetic. The term puzzle implies a sense of complexity or difficulty, which aligns with the nature of the tasks in the arithmetic section.
Select the most appropriate option to fill in the blank number 2.
Option 1: guess
Option 2: recollect
Option 3: imagine
Option 4: estimate
Correct Answer: recollect
In the context of the passage, the word recollect fits best. Swaminathan is sitting on his stool and shutting his eyes to recall or remember (recollect) what work he had for the day. The word implies the act of bringing information or memories back into one's mind.
Question : Which type of function does the analytical engine perform?
Option 1: Control functions
Option 2: Logical functions
Option 3: Relational functions
Option 4: Arithmetic functions
Correct Answer: Arithmetic functions
Solution : The correct option is Arithmetic functions.
The analytical engine intends to function for any mathematical action expressed in a finite number of steps. It includes both simple operations like addition, subtraction, multiplication, and division as well as more complex ones like algebra, calculus, and trigonometry.
Question : What is the full form of ALU?
Option 1: Alternative Logic Unit
Option 2: Arithmetic Logic Unit
Option 3: Arithmetic Least Unit
Option 4: Arithmetic Local Unit
Correct Answer: Arithmetic Logic Unit
Solution : The correct answer is the Arithmetic Logic Unit.
The ALU (Arithmetic Logic Unit) is a key component of a computer's central processing unit (CPU), performing arithmetic (addition, subtraction, multiplication, and division) and logical (comparisons and bitwise operations) operations on data.
Question : C. P. U. consists of ____.
Option 1: Arithmetic and Logical Unit and Register
Option 2: Arithmetic and Logical unit, Register and Control unit
Option 3: System Unit and Memory
Option 4: Hard disk and Control unit
Correct Answer: Arithmetic and Logical unit, Register and Control unit
Solution : The correct answer is Arithmetic and Logical Unit, Register and Control unit.
The CPU, or Central Processing Unit, serves as the computer's brain. It comprises three essential components: The ALU (Arithmetic and Logic Unit), Register, and Control Unit. The Control Unit is tasked with receiving input from peripheral devices and the processing system in handling the data. The ALU is responsible for executing all logical operations, thereby processing the data. Meanwhile, the Register stores data in the memory for future retrieval.
Question : Which component is mainly responsible for doing calculations on the computer?
Option 1: Random access memory
Option 2: Control unit
Option 3: Arithmetic logic unit
Option 4: Hard disk
Correct Answer: Arithmetic logic unit
Solution : The correct answer is the Arithmetic logic unit.
The Arithmetic Logic Unit (ALU) is a crucial computer element primarily tasked with performing arithmetic and logical computations. As an integral part of the Central Processing Unit (CPU), the ALU takes charge of various operations, including addition, subtraction, multiplication, division, and other logical processes. Its pivotal role lies in the execution of program instructions and the manipulation of data within the computer system.
Question : Arithmetic and Logic Unit
I. perform Arithmetic operations
II. Store Data
III. Perform comparisons
IV Communicate with input devices
Which of the following is true?
Option 1: I only
Option 2: III only
Option 3: I and II
Option 4: I and III
Correct Answer: I and III
Solution : The correct option is I and III.
The claim that the Arithmetic and Logic Unit (ALU) performs arithmetic operations, stores data, performs comparisons, and communicates with input devices is correct. The arithmetic and logical operations on the information stored in the computer's memory are carried out by the ALU.
