RBI Tests Blood Relations<\/h2>\n\n\n\n
Blood Relations questions in RBI exams test logical reasoning and analytical ability. PracticeMock provides a wide range of RBI-level Blood Relation questions based on actual exam patterns. These include direct, coded, and puzzle-based problems like: “Pointing to a girl, Raj said, ‘She is the daughter of the only sister of my father.’ How is the girl related to Raj?”<\/em> Such questions demand a clear understanding of family hierarchies and relationship chains. Practicing regularly with these mock tests improves speed and accuracy. Detailed solutions and tricks provided by PracticeMock help candidates master even the most complex relation-based problems effectively.<\/p>\n\n\n\n <\/p>\n\n\n\n Before we dive into the sample questions, let\u2019s take a look at the best tips to master Blood Relations questions:<\/p>\n\n\n\n Don\u2019t try to solve these questions in your head. It\u2019s easy to get lost. Use symbols or letters to represent family members and link them logically. <\/p>\n\n\n\n Here are some tips:<\/p>\n\n\n\n Many questions hinge on gender-specific roles like brother, sister, aunt, etc. To answer such questions, never assume gender and find keywords. <\/p>\n\n\n\n Here’s how to do it:<\/p>\n\n\n\n Sometimes, it\u2019s easier to start from the end of the statement. So, try solving it backwards if the forward way seems confusing.<\/p>\n\n\n\n Let\u2019s break it down:<\/p>\n\n\n\n Blood Relations questions come in multiple formats. Hence, you need to practice all common types to increase confidence and accuracy.<\/p>\n\n\n\n Use this simple process:<\/p>\n\n\n\n Speed matters a lot in the RBI Grade B exam. So, cultivate a habit of solving each question in under 1 minute.<\/p>\n\n\n\n Here\u2019s the way to go about it:<\/p>\n\n\n\n Now that you’ve understood the concept and tricks to solve blood relation questions, you must refer to the sample questions below and start practising. You must practice at least 50 questions to get a good understanding of this topic and to get a smooth flow when solving the questions. It’s imperative that when solving blood relations questions, you will make some mistakes. To avoid this situation, we are providing you with a list of ‘mistakes to avoid’. Knowing and avoiding these mistakes will definitely save you a lot of time, effort and marks. Have a look:<\/p>\n\n\n\n Sometimes a question has a narrator who describes their situation: “The sister of my father’s uncle…”. In this kind of situation, always assume the narrator as yourself and proceed with solving the question. If you go by the narrator’s perspective, it may take some time to draw the family-tree whereas when you assume yourself the narrator, you can visualize your own family, check the relations and answer the question in less time.<\/p>\n\n\n\n Who is Golu? Male or female? What about Lucky or Kiran? These names can create confusion in an aspirant’s mind, as they may be biased towards some names being male or female. Never assume any gender because of names and keep all the options open.<\/p>\n\n\n\n If the info ‘only son’ is provided it means that parents don’t have any other son but they may have a number of daughters. Keep this in mind.<\/p>\n\n\n\n In a complex question, you may get confused about maternal and parental relationships. The best policy in this case is to draw a family tree where you have clearly branched out the relatives of both sides.<\/p>\n\n\n\n You need to pay special attention to keywords such as ‘only’, ‘not’, ‘either’ and ‘neither’. Usage of these words carry a lot of weightage and even a little bit of misinterpreation can change the answer of the question.<\/p>\n\n\n\n Directions [1-2]:<\/strong> Answer the questions based on the information given below:<\/p>\n\n\n\n In a certain language,<\/p>\n\n\n\n ‘A $ B’ means ‘B is wife to A’,<\/p>\n\n\n\n ‘A # B’ means ‘A is daughter of B’,<\/p>\n\n\n\n ‘A @ B’ means ‘B is son of A’,<\/p>\n\n\n\n ‘A % B’ means ‘A is mother of B’,<\/p>\n\n\n\n ‘A & B’ means ‘B is sister of A’,<\/p>\n\n\n\n ‘A \u00a9 B’ means ‘A is husband of B’.<\/p>\n\n\n\n Question 1:<\/strong> If “P $ Q & R # S \u00a9 T & U @ O \u00a9 L % N” is definitely true, then how is R related to N’s father’s mother?<\/p>\n\n\n\n A) Aunt<\/p>\n\n\n\n B) Mother-in-law<\/p>\n\n\n\n C) Niece<\/p>\n\n\n\n D) Daughter-in-law<\/p>\n\n\n\n E) Cannot be determined<\/p>\n\n\n\n Solution:<\/strong><\/p>\n\n\n\n Given code: P $ Q & R # S \u00a9 T & U @ O \u00a9 L % N<\/p>\n\n\n\n After decoding the code, we get<\/p>\n\n\n\n P is husband of Q, who is sister of R.
