In such a situation, it is very important to prepare the complex topics on a priority basis, as they require much practice and to practice, you require time. As it cannot be prepared in the last 5-6 days so this is the appropriate time to prepare such topics. Preparing well for this topic not only boosts your Quant score but also strengthens your performance in related topics like Profit &amp; Loss, Ratio, and Data Interpretation. In this blog, we are going to discuss the common types of questions asked from simple and compound interest with examples, along with some preparation tips.

These small improvements can save 10-15 seconds per question in the exam.\u00a0<\/li>\n\n\n\n<li>Before heading towards solving the questions, revise fundamental formulas and relationships between principal, rate, time, and amount. This will help you in applying the formula while solving questions.\u00a0<\/li>\n\n\n\n<li>Begin with simple formula-based problems before moving to multi-concept questions that mix SI, CI, and percentages.<strong> <\/strong>For example, instead of calculating CI year by year, use the formula directly or apply percentage increase logic. Also, always check the time unit (years, months, or days) before applying the formula.<\/li>\n\n\n\n<li>Include at least two Arithmetic sectional mocks per week. Review every mistake and note where you commit mistakes- is it conceptual, calculative, or careless? Also, while solving the compound interest questions, make sure you avoid rounding too early in compound interest questions, try to keep at least two decimal points until the final answer.<br><\/li>\n\n\n\n<li>Make a formula sheet with all interest-related formulas and short tricks. Regular revision helps retain them during the final week before the exam.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion&nbsp;<\/h2>\n\n\n\n<p>In this article, we have discussed the types of common questions asked, along with the PDF to solve.
