Unlike Math, you don&#8217;t need long calculations. Unlike GK, you don&#8217;t need to memorize dates. Still, most candidates fail to score good marks in this section because they don&#8217;t prepare the most scoring topics. One of the most popular topics in Reasoning is Coding-Decoding.<\/p>\n\n\n\n<p>At first glance, seeing a question like <em>&#8220;If DELHI is coded as CCIDD, how is BOMBAY coded?&#8221;<\/em> might look like a secret spy message. But don&#8217;t worry. You don&#8217;t need to be James Bond to solve this.<\/p>\n\n\n\n<p><strong>Here is the secret:<\/strong> Coding-Decoding is just a game of patterns. The examiner simply shifts letters forward or backward (like A becomes B, or A becomes Z). Once you understand the rule, you can solve these questions in 10-15 seconds. To help you master this topic, we have collected the most repeated Coding-Decoding questions from previous Railway exams. We have compiled them into a free PDF that you can download from this blog.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-16018d1d wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link has-white-color has-vivid-cyan-blue-background-color has-text-color has-background has-link-color wp-element-button\" href=\"https:\/\/www.practicemock.com\/railway-rrb-ntpc-test-series\/?next=https%3A%2F%2Fs1.practicemock.com%2Fexams%2F%3Fc%3Dssctopiclr%26i%3Dssc&amp;ref=14954\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Attempt Free Coding-Decoding Tests for RRB NTPC Exam<\/strong><\/a><\/div>\n<\/div>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why is Coding-Decoding Important for RRB NTPC?<\/h2>\n\n\n\n<p>In both CBT-1 and CBT-2, this topic is a goldmine for marks.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>High Weightage:<\/strong> You can expect <strong>3 to 5 questions<\/strong> in every shift.

class=\"wp-block-heading\">How to Prepare for Coding-Decoding Easily?<\/h2>\n\n\n\n<p>Here, we have provided some tips and tricks to solve coding-decoding questions easily in the exam.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Learn EJOTY:<\/strong> This is the best trick. Remember <strong>E-J-O-T-Y<\/strong> corresponds to <strong>5-10-15-20-25<\/strong>. If you need to find &#8216;T&#8217;, you know it&#8217;s 20 instantly. If you need &#8216;S&#8217;, it&#8217;s just before T, so 19.<\/li>\n\n\n\n<li><strong>Write A to Z:<\/strong> As soon as you get your rough sheet in the exam hall, write A to M in one line and N to Z right below it (backwards). This helps you find <strong>Opposite Pairs<\/strong> (like A-Z, B-Y, C-X) instantly.<\/li>\n\n\n\n<li><strong>Check the First and Last:<\/strong> Don&#8217;t solve the whole word. Check the code for the first and last letter. Usually, you can find the correct option just by that.<\/li>\n\n\n\n<li><strong>Practice Daily:<\/strong> Solving 10 questions a day keeps the logic fresh.
