But, with the right tricks, you can save time and solve them faster.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1. Learn Basic Formulas First<\/strong><\/h3>\n\n\n\n<p>Understanding formulas is the base of solving these questions. Without this, shortcuts won\u2019t help.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Simple Interest = (P \u00d7 R \u00d7 T)\/100<\/li>\n\n\n\n<li>Compound Interest = A \u2013 P<\/li>\n\n\n\n<li>A = P(1 + R\/100)^T<\/li>\n\n\n\n<li>Know P = Principal, R = Rate, T = Time<\/li>\n\n\n\n<li>Learn when to use which formula<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. Convert Percentages Smartly<\/strong><\/h3>\n\n\n\n<p>Interest questions involve lots of percentages. So, get comfortable converting them.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>10% = 10\/100 = 1\/10<\/li>\n\n\n\n<li>5% = 1\/20, 12.5% = 1\/8<\/li>\n\n\n\n<li>Use fraction form to speed up<\/li>\n\n\n\n<li>Know recurring percentages used in exams<\/li>\n\n\n\n<li>Practice converting decimals to fractions<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. Break Time Periods<\/strong><\/h3>\n\n\n\n<p>When interest is calculated half-yearly or quarterly, split time properly.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1 year = 2 half-years<\/li>\n\n\n\n<li>1 year = 4 quarters<\/li>\n\n\n\n<li>Adjust rate per period<\/li>\n\n\n\n<li>Use updated time and rate in formulas<\/li>\n\n\n\n<li>Avoid confusion with total time<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4. Use Short Tricks for CI<\/strong><\/h3>\n\n\n\n<p>For small values and short time, tricks work better than formulas.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>CI for 2 years = SI + (SI \u00d7 R)\/100<\/li>\n\n\n\n<li>Use percentage method for faster CI<\/li>\n\n\n\n<li>Try difference between CI and SI<\/li>\n\n\n\n<li>Break compound rate into parts<\/li>\n\n\n\n<li>Try ratio-based questions<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>5. Practice Mental Calculation<\/strong><\/h3>\n\n\n\n<p>To save time in exams, reduce pen-paper use.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Multiply in steps mentally<\/li>\n\n\n\n<li>Round off for quicker estimates<\/li>\n\n\n\n<li>Skip long divisions<\/li>\n\n\n\n<li>Practice tables and squares<\/li>\n\n\n\n<li>Keep paper clean for rough work<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Important Sample Questions on Simple &amp; Compound Interest<\/strong><\/h2>\n\n\n\n<p><strong>Question 1:<\/strong>&nbsp;Anand invested a certain amount of sum for five years in a scheme offering a compound interest of 20% p.a. compounded annually for first 2 years and simple interest of 15% p.a. on the accumulated sum for rest of the time.
