BEG

x = 5

if x = 10:
    print("Hi")
else:
    print("Bye")

II.
BEG

x = 5

if x == 5:
    print("Hi")
else
    print("Bye")

III.
BEG

x = 5

if x != 10:
    print("Hi")
else:
    print("Bye")

IV.
BEG

x = 5

if x =< 10:
    print("Hi")
else:
    print("Bye")

V.
BEG

x = 5

if x > 10:
    
else:
    print("Bye")

VI.
BEG
```
x = 5

if x + 2 > 10:
    print("Hi")
```

VII.
BEG

x = 5

if x > 10:
print("Hi")    
else:
    print("Bye")

What will be the output for the programs given above?

You have to predict the output yourself without running/executing the code.

Hi
Bye

Expected Output:

// case 1
Enter withdrawal amount: 750   // user input
A transaction fee will not be applied.

// case 2
Enter withdrawal amount: 2650   // user input
A transaction fee will be applied.

Q6.
BEG

At the airport cargo counter, packages are checked based on their size. Instead of actual weight, they use a volumetric weight formula to decide if the package is too heavy to ship. Write a program that ask the user to enter the length, breadth, and height of the package in cm, then calculate the volumetric weight in kg and finally tells if the package is accepted for shipping or not.

The formula is: Volumetric Weight = (Length x Breadth x Height) / 5000
If the package’s volumetric weight is more than 20 kg then it’s considered too heavy for air shipping.

Expected Output:

// case 1
Enter the length of the package (in cm): 40   // user input
Enter the breadth of the package (in cm): 30   // user input
Enter the height of the package (in cm): 20   // user input

Volumetric weight: 4.8 kg  
Package accepted for shipping.

// case 2
Enter the length of the package (in cm): 100   // user input
Enter the breadth of the package (in cm): 80   // user input
Enter the height of the package (in cm): 50   // user input

Volumetric weight: 80.0 kg  
Package too heavy for air shipping!

At the college library, books can be borrowed and returned by students. To manage everything efficiently, they need a system to check students’ borrowing history and pending dues. Write a program that,

Asks the user if they have borrowed any book or not.
If they haven’t borrowed any book, they are immediately allowed to borrow a new one.
If they have borrowed a book, the system then asks how many days it has been since they borrowed it.
- If the number of days is 14 or less, they are allowed to borrow another book.
- If the number of days is more than 14, they are told the number of overdue days and asked to pay a fine of rs.1 per day before they can borrow a new book.

Write a program for this.

Expected Output:

// case 1
Did you borrow any book previously? (yes/no): no   // user input
You can borrow a new book. No pending returns.

// case 2
Did you borrow any book previously? (yes/no): yes   // user input
How many days ago did you borrow the book?: 10   // user input
Book returned within allowed time. You can borrow a new book.

// case 3
Did you borrow any book previously? (yes/no): yes   // user input
How many days ago did you borrow the book?: 20   // user input
Your book return is overdue. You have a pending fine of rs.6.
Please clear the fine before borrowing a new book.

At a city’s traffic control system, drivers are monitored for speed violations. The city has a strict speed policy - if a driver stays within the speed limit, they can continue without any fine. However, if they exceed the limit, fines are imposed depending on how much they overspeed.

Write a program that asks the driver for their current speed and informs them if they are safe or what fine they need to pay.

If the speed is 60 km/h or below, no fine is issued.
If the speed is between 61 and 80 km/h, a fine of rs.500 is issued.
If the speed is above 80 km/h, a fine of rs.1000 is issued.

Expected Output:

// case 1
Enter your current speed (in km/h): 75   // user input
You have exceeded the speed limit. A fine of rs.500 is applicable.

// case 2
Enter your current speed (in km/h): 95   // user input
You have exceeded the speed limit. A fine of rs.1000 is applicable.

At the city’s electricity board, household electricity bills are calculated based on the number of units consumed in a month. The board follows a slab system where different rates apply based on consumption levels.

Write a program that asks the user to enter the total number of electricity units consumed for the month, then calculates and displays the final bill amount according to the following rules:

For the first 100 units, the charge is rs.3 per unit.
For the next 100 units (units 101 to 200), the charge is rs.4 per unit.
For any units beyond 200, the charge is rs.5 per unit.

Expected Output:

// case 1
Enter total electricity units consumed: 150   // user input
Electricity Bill: rs.500

// First 100 units: 100 x rs.3 = rs.300, Next 50 units: 50 x rs.4 = rs.200
// Total = rs.300 + rs.200 = rs.500

// case 2
Enter total electricity units consumed: 250   // user input
Electricity Bill: rs.950

// First 100 units: 100 x rs.3 = rs.300, Next 100 units: 100 x rs.4 = rs.400
// Remaining 50 units: 50 x rs.5 = rs.250
// Total = rs.300 + rs.400 + rs.250 = rs.950
