SECTION B: Structured Questions
[65 Marks)
• Answer all the questions in the provided booklet.
• The section consists of 8 questions.
1. Convert the following nested IF statement to a combined IF statement (Unnest the
following nested IF statement). [4 Marks)
IF (final Mark>= 50} THEN
IF(examMark >= 40) THEN
DISPLAY"Pass."
ENDIF
ENDIF
2. Write a pseudocode that will assist a car dealership company to determine the selling
price of a vehicle based on the brand. The program should accept the brand and price of a
vehicle from a user and calculate the selling price of that vehicle. If the user enters a
brand other than Audi, BMW or Mercedez Benz, the program should display "Invalid
brand". The program should then display the brand and the selling price of the vehicle to
the screen. The selling price is calculated by subtracting the discount from the price of the
vehicle.
Your pseudocode must satisfy all the rules below.
• If the brand is an Audi, the discount is 5%.
• If the brand is a BIVIW,the discount is 6%.
• If the brand is a Mercedez Benz, the discount is 7%.
a. Identify the inputs and outputs in the problem above. [4 Marks)
b. Write a complete pseudocode for the problem above. [10 Marks)

3. Covert the following pseudocode into a flowchart. [6 Marks)
Start
count= 10
WHILE (count<= 20)
DISPLAYcount
count = count + 1
ENDWHILE
End
4. Convert the following Case Structure to a Linear IF Statement pseudocode. [9 Marks]
Start
Prompt user for response
Get response
CASEOF (response) {
1: X = X + y
2: X = x-y
3: X = X * y
4: x = x / y
default: Display "No output."
ENDCASE
End

5. Convert the following pseudocode into a flowchart. [9 Marks]
Start
PROMPT user for credit score
GET creditScore
IF (creditScore > 700) THEN
interestRate = creditScore + (creditScore * 0.15)
ELSEIF (creditScore >= 600) THEN
interestRate = creditScore + (creditScore * 0.20)
ELSE
interestRate = creditScore + (creditScore * 0.25)
ENDIF
ENDIF
DISPLAYinterestRate
End
6. Write a pseudocode to assist a librarian in categorizing books based on their publication
years. The program should prompt the librarian for the publication year of a book. Then,
it should categorize the book into one of the following age categories: "Classic",
"Modern", or "Contemporary". Use the variable currentYear to represent the current
year when the librarian is categorizing the book. (8 Marks]
The criteria for categorisation are as follows:
Classic:Books published more than 50 years ago.
Modern: Books published between 20 and 50 years ago (20 and 50 years inclusive).
