Simple interest Level - 1
The Simple Interest Level 1 Assessment is a foundational, speed-focused module consisting of 50 questions. Designed to build core quantitative aptitude, this test evaluates a candidate's ability to swiftly apply basic financial formulas, understand principal-amount relationships, and calculate interest over varying time periods without the use of a calculator.

Normal practice, or a Simulated test
The same questions, either way. Normal practice teaches; the simulated test tells you where you stand.
Normal
UntimedEvery question on one page, loading as you scroll. Choose an option and see straight away whether it was right.
- No timer. Nothing to start and nothing to submit. Stop whenever you like.
- Answered as you choose. Tap an option and it is marked at once, with the correct answer shown.
- Solutions in place. The explanation, and the video where one has been added, sit under the question.
- Open to guests. Normal practice needs no sign-in.
Simulated
Timed CBTThe computer-based test format: one clock, a question palette, and a score the moment you submit.
- A clock that does not pause. 75 minutes from the moment you begin, and the paper is submitted for you when it reaches zero.
- Question palette. Answered, not answered and marked for review, section by section, as the real interface has it.
- Full screen, proctored. The test takes over the screen; leaving it three times submits the paper.
- Answers hidden until you submit. The key, the explanations and your score all arrive together at the end.
About this test
This specific 50-question module, often featured in comprehensive quantitative aptitude test series like Padhai Vadhai, is the perfect starting point for mastering commercial mathematics. It strips away the complexities of compound interest to focus purely on linear growth, testing both accuracy and calculation speed.
Exam Structure & Target:
Total Questions: 50.
Ideal Time Limit: 40–45 minutes, testing the candidate's ability to solve each question in under a minute.
Core Focus: Direct application of fundamental concepts rather than complex, multi-step word problems.
Syllabus & Core Question Types:
Direct Formula Application: The bulk of the exam requires rapid mental math using the core formula: SI = (P * R * T) / 100, where P is Principal, R is Rate of Interest, and T is Time.
Finding the Unknown Variable: Questions where the Simple Interest is given, and the candidate must manipulate the formula to find the Rate: R = (100 * SI) / (P * T) or Time: T = (100 * SI) / (P * R).
Amount Calculations: Understanding the relationship between Principal and Amount: Amount = Principal + SI.
Multiples and Times: Classic "sitter" questions such as finding the rate of interest if a sum of money doubles itself in 'x' years, or triples itself in 'y' years.
Fractional Time Periods: Calculating interest when the time is given in months or days (e.g., finding the SI for 73 days or 8 months) to test basic unit conversion skills.
Exam Pattern & Strategy:
Difficulty Level: Easy.
Scoring: +1 for correct answers, -0.25 for incorrect answers.
Strategy: Since the concepts are straightforward, the real test is avoiding silly calculation errors and managing time. Candidates are encouraged to use fraction equivalents for percentages (e.g., using 1/8 instead of 12.5%) to drastically cut down calculation time
