Top 5 Videos on Simple Interest and Compound Interest: Maths for SSC Preparation by PW

Simple Interest and Compound Interest can become confusing when questions involve changing rates, different time periods, mixed investments or comparisons between SI and CI. You may know the formulas but still make mistakes while calculating the principal, rate, time or final amount. Choosing the right method under exam time limits can also be difficult.

PW videos on SI and CI help you work through these concepts with examples, percentage-based methods, shortcuts and question practice. You can start with the basics, revise both topics together and practise different question patterns to improve your calculation speed and accuracy.

Video 1: Master SI and CI with Complete One-Shot Revision and Mixed Questions

This one-shot video covers Simple Interest and Compound Interest from the basics. You revise principal, rate, time, amount, percentage-based reasoning, direct relationships and compound growth. The video also includes the tree method, powers and roots for different time periods, and mixed SI and CI questions. It moves from basic concepts to faster solving methods, helping you connect different question types in one revision session. 

Watch it when you need to revise the complete topic, strengthen your understanding and prepare for chapter-based tests or SSC Maths mock exams.

Video 2: Build Strong Simple Interest Basics with Percentage-Based Solving Methods

This video focuses on Simple Interest and explains how principal, rate, time, interest and amount are connected through percentage calculations. You practise converting months into years, finding missing values and solving questions using formula-based and alternative methods. 

The video also includes examples, timed questions, polls and mental calculation prompts. If you find direct SI questions difficult or make mistakes while applying the formula, this class can help you strengthen your basics, improve calculation accuracy and prepare for more advanced SI and CI problems.

Video 3: Practise Top SI and CI Questions with Shortcuts and Timed Solving

This question-practice class covers changing rates and time periods, principal comparisons, combined investments, total and average rates, and compound interest over multiple years. You also practise ratio, percentage and mental calculation methods as the questions become more challenging. Timed options and step-by-step solutions help you understand how to approach different problem patterns. 

Watch this video after learning the basic concepts to improve your question selection, reduce calculation time and prepare for SSC CHSL Maths practice. You can also revise the SSC CGL Maths SI and CI concepts and questions.

Video 4: Connect SI and CI Concepts Through Mixed Questions and Faster Methods

This video combines Simple Interest and Compound Interest through concept revision and practice examples. You cover percentage and ratio methods, successive changes, effective rates, powers and time relationships, the tree method, golden ratio, and differences between SI and CI. Questions follow the concepts to help you understand how each method works in different situations. 

Choose this video when you have studied both topics separately and want to connect them through mixed practice. It can help you recognise question patterns, select suitable methods and prepare for the Quantitative Aptitude section. For additional topic-wise revision, refer to SSC CGL Maths notes and practice resources.

Video 5: Improve Simple Interest Accuracy with Focused Question Practice

This video focuses on Simple Interest through direct examples and percentage-based calculations. You practise finding interest, rate, time, principal and amount, comparing investments, identifying when money reaches a particular multiple, and analysing changes in rate, time or principal. Written solutions, polls, mental shortcuts and quick checks help you follow each calculation. 

Use this video after revising the basic formulas to improve your accuracy and speed in direct SI questions. You can combine the video with a regular SSC Maths preparation strategy to build a consistent practice routine.

These five PW videos help you prepare Simple Interest and Compound Interest through concept revision, percentage-based calculations, shortcuts and mixed question practice. Start with the one-shot video if you need to revise both topics, then use the focused lessons to strengthen your basics and solve exam-level questions. Practise regularly and assess your progress through the PW SSC test series. This combination can help you identify calculation errors, improve question-solving speed and approach SSC Maths questions with greater confidence.
