The questions based on blood relations are important part of Logical Reasoning section of Common Admission Test (CAT).
While our previous article on Logical Reasoning covered the concept of Seating Arrangements sets, this article brings out tips on solving questions based on Blood Relations.
Strategy to solve: Questions based on Blood Relations are, although a little complex, they can be solved faster, if one has the understanding of Family Tree. The irony of the present modern world is that we have to devise various ways and means to solve them whereas, solutions to such questions are on the tips of illiterate old aged people. However, the basic strategy to solve such questions is to know the various relations among family members. Spread out the understanding and follow the relations to at least three four generations like Great Grand parents and children, Aunts, uncles, cousins. Don’t be afraid even when the simple relation is described in a circuitous manner, just place the layers of relationship above or below each of them. This will help you to form the family tree in an easy manner.
Types of Questions- Try to remember good old childhood days when we spent our summer vacation with the grandparents or the hot summer noons and cool nights, where the process of exchange of riddles based on various hypothetical situations with Blood Relations continued which gave the small brain a good storming but made us understand the logical coherence of relations. Alas! It happens no more and we remain glued to the electronic media, social sites, thus losing out on the obvious knowledge of blood relationships and family tree. Now, we have to study the pattern and system to follow such problems. Such questions could come in singles or in sets. They may be statement based or puzzle based
1) Statement Based questions – They are usually presented with a single question
1. A is the father of B, but B is not the Son of A –Ans. Very simple – answer is daughter.
2. Radhe and Sunita were going on foot from one village to another on a summer afternoon. Sunita felt thirsty and wished to have some water to quench her thirst. Radhe found out a well with sweet water and asked Sunita to accompany him to the well. The other ladies who were drawing water from the well gave water and some eatables to Sunita. One of them asked Sunita the relationship between her and Radhe to which Sunita replied that Radhe’s mother-in-law and her mother-in-law were mother and daughter. What could be the relationship between Radhe and Sunita.
i) Father and daughter ii) Husband and wife iii) Father in law and Daughter in Law
iv) Brother in law and sister in law
Answer – iii) Father in Law and Daughter in law. Eliminate the first option as it indicates mothers not mother in law; second option can’t be true; ivth option again does not establish any blood relation. Although easy to solve – yet difficult to solve unless you follow the – Family tree of relations.
