1. Body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. The Table below shows how healthy you are with respect to your BMI.

The Formula That we use For BMI is :

$$bmi = weight(kgs)/height(cms)^2*10000$$

Take Weight and height from the user and Calculate BMI.​

Solution

First we will take weight and height from user with the help of user input.

weight = int(input('Enter your weight : '))

height = int(input('Enter your height : '))

Then we will calculate BMI , Now say if we want only two decimal values , we can use round() Function.

bmi = round(weight / height ** 2 * 10000)

print('Your BMI is',bmi)

4. Take Principle, Rate, and Time From User and Calculate Simple Interest.

Formula For Simple Interest is:

$$Simple Interest = Principle * Rate * Time / 100$$

Solution

principle = int(input('Enter the amount : '))

rate = int(input('Rate : '))

time = int(input('Time : '))

simple_interest = principle * rate * time / 100

print('Simple Interest is',simple_interest)

5. Your task is to take name and age and location from user and print the following message :

Hello Everyone , I am xyz and i am xyz years old and i live in xyz.

Solution

name = input('Enter your name : ')

age = input('What is your age ? ')

location = input('Where do you live ? ')

print('Hello Everyone , I am' ,name, 'and i am', age, 'years old and i live in', location,'.')

6. Suppose there are many N numbers of people in the Army. We need to distribute them in G groups. Take the number of people from users and the Number of Groups and tell how many are left without Group.

Solution

n = int(input('Number of Army People : '))

g = int(input('How many groups do we need ? '))

rest = n%g

print('Remaining People :',rest)

7.Take Temperature in Fahrenheit and convert it into Celsius.

Formula: C = 5/9 * ( F - 32 )

Solution

# Ask user for temperature in Fahrenheit
fahrenheit = float(input("Enter temperature in Fahrenheit: "))

# Convert to Celsius
celsius = (fahrenheit - 32) * 5/9

# Print result
print(fahrenheit,' degrees Fahrenheit is equal to',celsius,'degrees Celsius.")

1. Take two variables from user value and power and print the solution value raised to power. Such as value = 3 and power = 2 then solution is 9

Solution

value = int(input('Enter the Number : '))
power = int(input('Enter the power : '))

solution = value ** power
print('Solution is', solution)

1. Tom had y amount in his bank and jeff withdrew x amount where x is always less than y. Print the remaining balance in Tom's account. Take x and y from the user.

Solution

y = int(input("Enter Tom's account balance : "))
x = int(input('Enter withdrawal amount : '))

balance = y - x
print('Remaining balance :', balance)

1. Take the base and height of a triangle from the user and calculate the area of the triangle. area=(base * height)*1/2

Solution

base=int(input('Enter the base of the triangle:'))
height=int(input('Enter the height of the triangle:'))
area=(base*height)*1/2
print('Area of the triangle is',area)

1. Take 5 numbers from the user and calculate average of those numbers.

(average=sum of data/number of data)

Solution

num1=int(input('Enter first number:'))
num2=int(input('Enter first number:'))
num3=int(input('Enter first number:'))
num4=int(input('Enter first number:'))
num5=int(input('Enter first number:'))

average=(num1+num2+num3+num4+num5)/5
print('Average of the numbers',average)

1. Take the sides of a triangle and check whether it follows Pythagoras' theorem. sq. of base + sq. of height=sq. of hypotenuse

Solution

base=int(input('Enter base of the triangle:'))
height=int(input('Enter height of the triangle:'))
hypotnuse=int(input('Enter hypotnuse of the triangle:'))
result=base**2 + height **2
print('pythagoras theorem:',result==hypotnuse**2)

1. Take the length and breadth of a rectangle and find the perimeter of the rectangle perimeter= 2 * (length + breadth)

Solution

length=int(input('Enter length of the rectangle:'))
breadth=int(input('Enter breadth of the rectangle:'))

perimeter= 2* (length + breadth)
print('Perimeter of the rectangle with sides', length,'and',breadth,' will be', perimeter)

1. Take the side of a cube in cm and calculate the volume of the cube. volume= side * side * side

Solution

side=int(input('Enter side of a cube:')
volume= side ** 3

print('Volume of the cube:',volume,'cubic cm')

1. Take the length, breadth, and height of a cuboid in cm and calculate the volume of the cuboid. volume= length * breadth * height
