'A @ B' means 'A is the father of B'. 'A $ B' means 'A is the wife of B'. 'A # B' means 'A is the daughter of B'. 'A * B' means 'A is the son of B'. How is U related to Y in 'U#V@W*X#Y'?

  • A.Daughter's son
  • B.Daughter's daughter
  • C.Daughter
  • D.Son

Answer: B

U is the daughter of X's daughter, so U is Y's daughter's daughter. The chain U # V @ W * X # Y reads: U is the daughter of V; V is the father of W; W is the son of X; X is the daughter of Y. V is W's father and X is W's parent, so X and V are the parents of W, and U is also V's daughter, which makes U a child of X and V. X is the daughter of Y. Hence U is the daughter of Y's daughter, which is the daughter's daughter. Daughter's son is wrong because U is female, and Daughter or Son would make U a direct child of Y, which the chain does not say.
