Student Average Grade Using Classes in Python

Machine Problem in Python

1. Create an app that computes students average solve using classes.

2. The user will input the following (Name, Math, Science and English Grade)

3. Create a Class called Students

4. Use the init function to collect the student information (Name, Math, Science and English Grade)

5. Create a function that will perform the computation of the average

6. Create a function that will display the result

SAMPLE OUTPUT:

Name: Jake R. Pomperada

Math: 90

Science: 90

English: 90

Average: 90 (Passed)

Simple Interest in AngularJS

Machine Problem

Write a program to ask the user to give principal amount, time, and rate to calculate the simple interest. Use the following formula below.

Formula:

SI = (P * T * R) / 100

Where:

P = principal amount

T = time

R = rate

SI = simple interest
