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 Question and Statements?
Statement-1, Statement-2 and Statement-3 are sufficient to answer the Question.
Statement-1, Statement-3 and Statement-4 are sufficient to answer the Question.
All four statements together are sufficient to answer the Question.
All four statements are not sufficient to answer the Question.
Solution
From all four statements: A and B are married; D is father of C; E is D's son; A and C are sisters. Since A and C are sisters and D is C's father, D is also A's father. E (D's son) is therefore A's brother. A is married to B, so E is the brother-in-law of B. All four statements together are needed and sufficient.
