Consider the following including the Question and the Statements: There are 5 members A, B, C, D, E in a family. Question: What is the relation of E to B? Statement- 1: A and B are a married couple. Statement- 2: D is the father of C. Statement- 3: E is D's son. Statement- 4: A and C are sisters. Which one of the following is correct in respect of the above Questions and Statements?
- AStatement-1, Statement-2 and Statement-3 are sufficient to answer the Question
- BStatement-1, Statement-3 and Statement-4 are sufficient to answer the Question
- CAll four statement together are sufficient to answer the QuestionCorrect
- DAll four statements are not sufficient to answer the Question.
Explanation
To determine the relation of E to B, we need to connect them through the family tree using all four statements:
From Statement 1, we know A and B are a married couple. From Statement 4, we know A and C are sisters. This implies A is female and B is her husband (male). From Statement 2, we know D is the father of C. Since A and C are sisters, D must also be the father of A. From Statement 3, we know E is the son of D. This makes E the brother of A and C.
By combining all four statements, we establish that E is the brother of A, and since A is married to B, E is the brother in law of B.
If any statement is missing, the link is broken. For example, without Statement 4, we cannot link D and E to the couple A and B. Without Statement 1, we do not know how B relates to the siblings. Therefore, all four statements together are sufficient to answer the question.
