Question 1 (5 points):
a. Analyze the importance of information technology tools in
administrative activities. Give an illustrative example.
Over the years, our Party and State have always determined that information
technology development is one of the solutions to modernize the administration and is
an important tool in the implementation of administrative reform. With the desire to
create fairness, transparency and efficiency, the application of information technology
in administrative reform has also been identified as an important driving force for
socio-economic development, reducing inconveniences for the public. people and
businesses, especially in the context of the industrial revolution 4.0.
Advantages
The computerization of the activities of state administrative agencies is both a
means and a pressure for administrative reform. Through IT application activities, the
administrative apparatus is easier to link together in performing tasks, the Government
also through it to run the state apparatus quickly, efficientlyand accurately; better
control all activities of public authorities in the face of complex fluctuations of the
market economy in the period of integration and development.
Defect
However, it is the transparency in control and supervision that information
technology application activities bring that more or less put pressure on administrative
agencies because of all the stagnation and congestion of the public apparatus. It's easy
to see when something goes wrong. Thus, administrative reform and information
technology ultimately share the same purpose, which is to improve the quality and
efficiency of work, and to improve the transparency and reliability of management
information. . Information technology application and administrative reform activities
have a close organic relationship, interact, cannot be separated and need to be carried
out at the same time.
2. 2
For example: For example, the national public service portal with the address
'https://dichvucong.gov.vn/' has applied the information technology industry in
completing complicated procedures that individuals, Businesses do not need to be
directly able to do it. Since the application has tens of millions of procedures to be
completed and handled ... .With such a utility website, it helps to improve
professionalism in handling cumbersome and troublesome administrative procedures
and waste of time.
b. What is function in excel? Explain the diffirences among SUM, SUMIF
and SUMIFS function. Take the illustrative examples to clarify.
A function is a predefined formula that performs calculations using specific
values, called arguments, in a particular order or structure. Functions can be used to
perform simple or complex calculations.
Function syntax
The following example of the ROUND function that rounds a number in cell
A10 illustrates the syntax of a function.
1. Structure. The structure of a function begins with an equal sign (=), followed
by the function name, an opening parenthesis, the arguments to the function are
separated by commas, and a closing parenthesis.
2. Function name. For a list of available functions, click a cell and press
SHIFT+F3.
3. Arguments. Arguments can be numbers, text, logical values like TRUE or
FALSE, arrays, error values like #N/A, or cell references. The argument that you
3. 3
specify must generate a valid value for that argument. Arguments can also be
constants, formulas, or other functions.
4. Argument tool tip. A tool tip with syntax and arguments appears as you type
the function. For example, type =ROUND( and the tooltip appears.The tooltipappears
only for built-in functions.
1. SUM function
The SUM function sums multiple individual cells, sums within a range, or even
multiple ranges in one go.
Function syntax: =SUM(number1,[number2],…)
Inside:
number1: equired argument, is the first number you want to add.
number2-255: optional argument, is the 2nd to 255thnumber you want to add.
For example, to calculate the total amount of goods in the data table of the figure
below, we have the following formula:
=SUM(F2:F10)
2. SUMIF function
The SUMIF function sums based on a condition.
4. 4
Function syntax: =SUMIF(range; criteria;[sum_range])
Inside:
Range: Is the selectedrange containing the condition cells
Criteria: Is the condition to execute this function
Sum_range: Area to be summed
For example, to calculate the total cost of red items, we have the following
formula:
=SUMIF(B2:B10;B3;F2:F10)
3. SUMIFS function
The SUMIFS function sums based on multiple conditions, unlike the SUMIF
function above, which can only sum based on 1 condition. You can also use this
function with only one condition.
Function syntax: =SUMIFS(sum_range, criteria_range1, criteria1,
[criteria_range2, criteria2], ...)
5. 5
Inside:
Sum_range: required argument, is the range to sum.
Criteria_range1: required argument, is the range containing the 1st condition
cells.
Criteria: required argument, is the 1st condition.
Criteria_range2…: optional argument, is the range containing the 2nd condition
cells onwards.
Criteria…: optional argument, is the 2nd condition onwards.
For example, to calculate the total cost of red items and have unit prices less than
5,000,000, we have the following formula:
=SUMIFS(F2:F10;B2:B10;B3;D2:D10;”<5000000″)
Compare functions
Functions Condition
SUM Unconditioned
SUMIF A condition
SUMIFS Multiple combination conditions

Question 2 (5 points):
a. Calculate the Revenue, Tax for each order and Net income.
Recipe :
Revenue = Unit Price * Quantity = C2 *D2 (Same with the rest)
Tax = Revenue * 2% = E2*F2 (Same with the rest)
Net income = Revenue – Tax = E2 - F2 (Same with the rest)
Total Quantity = SUM(D2:D10)
Total Revenus = SUM(E2:E10)
Total Tax = SUM(F2:F10)
Total Net income = SUM(G2:G10)
b. Calculate the total net income of products which has 10260 in Order ID.
7. 7
The total net income of products with 10260 in order ID is : 1711.3
Recipe : =SUMIF($A$2:$A$10,A4,$G$2:$G$10)
c. Calculate the Net income when Unit prices of those product increase by
5%, their Quantities decrease by 3%.
The unit price of those products increased by 5%, Their quantity decreased by
3%.
The net income when the Unit Price of those products increases by 5%, Their
Quantity decreases by 3% is : 2494.32687
Recipe : =SUM(G3:G11)
