These questions are asked every year in the exam in multiple formats, like puzzles or coded blood relations. These questions test your ability to interpret and analyse family relationships based on given statements.

All the female members of the family are represented with a \u2018\u2013\u2019 sign with their name.<\/p>\n\n\n\n<p>2. All the male members of the family are represented a \u2018+\u2019 sign with their name.<\/p>\n\n\n\n<p>3. The relation between two members of the family is shown by connecting a line.<\/p>\n\n\n\n<p>5. All the family members of the same generation are represented together. Ex: brothers, Sisters, cousins, wife, husband, etc.<\/p>\n\n\n\n<p>6. All the family members of the next generation are represented below in the family tree. Ex: grandparents are represented above the parents, who are represented above their child and so on.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"731\" height=\"457\" src=\"https:\/\/www.practicemock.com\/blog\/wp-content\/uploads\/2025\/07\/image-46.png\" alt=\"\" class=\"wp-image-162118\"\/><\/figure>\n\n\n\n<p><strong>Observation:<\/strong><strong><\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A is husband of B.<\/li>\n\n\n\n<li>D is the daughter of A.<\/li>\n\n\n\n<li>C is the brother of D<\/li>\n\n\n\n<li>G is wife of E.<\/li>\n\n\n\n<li>C is the brother-in-law of E.<\/li>\n\n\n\n<li>D is sister-in-law of J.<\/li>\n\n\n\n<li>E is father of H.<\/li>\n\n\n\n<li>D is mother of H.<\/li>\n\n\n\n<li>H is grandson of F.<\/li>\n\n\n\n<li>I is granddaughter of F.<\/li>\n\n\n\n<li>F is paternal grandfather of H<\/li>\n\n\n\n<li>G is paternal grandmother of H.<\/li>\n\n\n\n<li>A is maternal grandfather of H.<\/li>\n\n\n\n<li>B is maternal grandmother of H.<\/li>\n<\/ul>\n\n\n\n<p><strong>Below is a family tree table based on the above diagram that you can refer to:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Person<\/th><th>Relation<\/th><th>Related To<\/th><th>Additional Info<\/th><\/tr><\/thead><tbody><tr><td>A<\/td><td>Husband<\/td><td>B<\/td><td>A is male<\/td><\/tr><tr><td>B<\/td><td>Wife<\/td><td>A<\/td><td>B is female<\/td><\/tr><tr><td>D<\/td><td>Daughter<\/td><td>A &amp; B<\/td><td>D is female<\/td><\/tr><tr><td>C<\/td><td>Brother<\/td><td>D<\/td><td>C is male<\/td><\/tr><tr><td>C<\/td><td>Brother-in-law<\/td><td>E<\/td><td>C&#8217;s sister (D) is E&#8217;s wife<\/td><\/tr><tr><td>G<\/td><td>Wife<\/td><td>E<\/td><td>G is female<\/td><\/tr><tr><td>D<\/td><td>Sister-in-law<\/td><td>J<\/td><td>D is married to J&#8217;s brother<\/td><\/tr><tr><td>E<\/td><td>Father<\/td><td>H<\/td><td>E is male<\/td><\/tr><tr><td>D<\/td><td>Mother<\/td><td>H<\/td><td>D is female<\/td><\/tr><tr><td>H<\/td><td>Grandson<\/td><td>F<\/td><td>H is male<\/td><\/tr><tr><td>I<\/td><td>Granddaughter<\/td><td>F<\/td><td>I is female<\/td><\/tr><tr><td>F<\/td><td>Paternal Grandfather<\/td><td>H<\/td><td>F is E\u2019s father<\/td><\/tr><tr><td>G<\/td><td>Paternal Grandmother<\/td><td>H<\/td><td>G is E\u2019s wife<\/td><\/tr><tr><td>A<\/td><td>Maternal Grandfather<\/td><td>H<\/td><td>A is D\u2019s father<\/td><\/tr><tr><td>B<\/td><td>Maternal Grandmother<\/td><td>H<\/td><td>B is D\u2019s mother<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Example of Coded and Direct Blood Relation Questions With Solution<\/h2>\n\n\n\n<p>Below, we have provided an example of coded blood relation and direct blood relation questions with an explanation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Example 1: (Direct)<\/h3>\n\n\n\n<p><strong>Q:<\/strong> Pointing to a woman, Ravi said, &#8220;She is the daughter of the only son of my father.&#8221;<br><strong>A:<\/strong> The woman is Ravi\u2019s <strong>daughter<\/strong>.<\/p>\n\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\u201cOnly son of my father\u201d \u2192 Ravi himself<\/li>\n\n\n\n<li>\u201cShe is the daughter of Ravi\u201d \u2192 So she is Ravi\u2019s daughter.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Example 2: (Coded)<\/h3>\n\n\n\n<p><strong>Q:<\/strong> If A + B means A is the father of B, A &#8211; B means A is the sister of B, A * B means A is the mother of B, and A \u00f7 B means A is the brother of B, then what does <strong>P * Q + R<\/strong> mean?<\/p>\n\n\n\n<p><strong>A:<\/strong> P is the mother of Q, Q is the father of R \u2192 So, <strong>P is the grandmother of R<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Tips to Speed up Solving Blood Relation Questions<\/h2>\n\n\n\n<p>Follow the tips provided below to solve the blood relation questions quickly:<\/p>\n\n\n\n<p><strong>Tip 1:<\/strong> <strong>Step-by-step analysis<\/strong> \u2013 Don\u2019t jump to conclusions.<br><strong>Tip 2:<\/strong> <strong>Draw diagrams\/family trees<\/strong> \u2013 Especially helpful in puzzles.<br><strong>Tip 3: Identify gender<\/strong> from clues.<br><strong>Tip 4: Practice coded patterns<\/strong> for speed.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Disclaimer:<\/strong> This blog provides practice blood relation questions for RRB PO preparation.

Over the years, I've been a dedicated government job aspirant, having attempted various competitive exams conducted by the Government of India, including SSC JE, RRB JE, Banking &amp; Insurance exams, UPSC CDS, UPSC CSE and GPSC. This journey has provided me with deep insights into the examination patterns and preparation strategies. Currently, I channel this experience into my role as a passionate content writer at PracticeMock, where I strive to deliver accurate and relevant information to candidates preparing for Banking exams, guiding them effectively on their preparation journey.","url":"https:\/\/www.practicemock.com\/blog\/author\/sandhya\/"},{"@type":"Question","@id":"https:\/\/www.practicemock.com\/blog\/rrb-po-blood-relations-questions\/#faq-question-1753100843340","position":1,"url":"https:\/\/www.practicemock.com\/blog\/rrb-po-blood-relations-questions\/#faq-question-1753100843340","name":"Q1.
