Introduction to Coded Blood Relation Reasoning Questions for Bank Exams
Coded blood relation reasoning questions are a challenging and integral part of the reasoning ability section in bank exams, such as IBPS PO, SBI PO, RBI Assistant, IBPS Clerk, and other competitive banking tests. These questions require candidates to decode familial relationships represented by symbols or codes (e.g., + for father, – for mother), testing logical deduction, pattern recognition, and analytical skills.
Frequently appearing in both preliminary and mains phases, coded blood relation problems range from simple single-expression questions to complex puzzles involving multiple relationships or additional constraints. Typically contributing 3-5 questions in prelims and 5-8 in mains, mastering these questions can significantly enhance your reasoning score, which often carries 35-50 marks.
This article provides 30 coded blood relation reasoning questions, meticulously designed to mirror the difficulty and format of bank exams. The questions cover single expressions, multiple expressions, and puzzle-based scenarios, with multiple-choice options to simulate exam conditions. Answers and detailed explanations are provided in a hidden section at the end to support self-assessment and learning. Practice these questions to hone your decoding skills, improve accuracy, and excel in your bank exam preparation!
