'P @ Q' means 'P is the sister of Q' 'P & Q' means 'P is the father of Q' 'P # Q' means 'P is the brother of Q' If ' A @ B # C & D @ E, then how is D related to A?
A. sister's daughter
B. Daughter
C. brother's daughter
D. brother's son
Answer: Option C
Solution (By JKSSB Mock Tests)
A @ B → A sister of B. B # C → B brother of C (C male). C & D → C father of D. D @ E → D sister of E (D female). So A, B, C are siblings; A is sister of C. D is daughter of C, thus D is A's brother's daughter.
'A + B' means 'A is the father of B' 'A – B' means 'A is the mother of B' 'A × B' means 'A is the husband of B' 'A ÷ B' means 'A is the sister of B' If C ÷ M – S – K + T × Q, then which of the following statements is not correct?
Explanation:
C ÷ M → C sister of M. M – S → M mother of S. S – K → S mother of K. K + T → K father of T. T × Q → T husband of Q. K is father-in-law of Q (true). S is mother of K, so S is not father of T's father. Hence B is incorrect. C: S is daughter of C's sister M (true). D: M is mother of S, who is mother of K, so M is mother of K's mother (true).
