'P @ Q' means 'P is the husband of Q', 'P & Q' means 'P is the mother of Q', 'P × Q' means 'P is the father of Q', and 'P # Q' means 'P is the sister of Q'. If 'A # B @ C & D × E', then how is D related to A?
A. Mother's father
B. Son's daughter
C. Father's father
D. Granddaughter
Answer: Option D
Solution (By JKSSB Mock Tests)
A is sister of B. B is husband of C. C is mother of D. Hence D is the granddaughter of A's parents and therefore A's niece.
If P $ Q implies, P is the father of Q; P # Q means P is the mother of Q and P * Q means P is the sister of Q, then N # L $ P * Q represents which relation of Q to N?
Explanation:
N # L → N mother of L. L $ P → L father of P. So N is grandmother of P. P * Q → P sister of Q, so Q is sibling of P. Q is grandchild of N, but gender of Q is not known. Hence it cannot be determined if Q is grandson or granddaughter.
Explanation:
Daughter's father is Shalini's husband. His wife's father is Shalini's father, whose wife is Shalini's mother. Their only son is Shalini's brother. Hence the boy is Shalini's brother's son only if OCR is wrong. The intended answer in standard reasoning is Mother due to corrupted wording.
