A. Grandfather
B. Grandmother
C. Grandfather or Grandmother
D. Father
Answer: Option C
Solution (By JKExamLibrary)
S and T are siblings, and P is their parent. Q's mother is the sister of P, and both are children of M. Therefore, M is the grandparent of P's children (S and T). Since the gender of M is not defined, M can be either Grandfather or Grandmother.
Pointing to a photograph, a woman says, 'This man's son's sister is my mother-in-law.' How is the woman's husband related to the man in the photograph?
Explanation:
The man's son's sister is the man's daughter. This daughter is the woman's mother-in-law. The woman's husband is the son of this mother-in-law. Therefore, the woman's husband is the grandson of the man in the photograph.
Explanation:
A is son of C → C is mother of A (since C is sister of Q, C female). C and Q are sisters. Z is mother of Q, so Z is mother of C and Q. P is son of Z, so P is brother of C. Hence P is maternal uncle of A.
'P @ Q' means 'P is the sister of Q' 'P & Q' means 'P is the mother of Q' 'P # Q' means 'P is the husband of Q' If 'A # B & C @ D # E' then how is E related to B?
Explanation:
A # B → A husband of B. B & C → B mother of C. So C is daughter of A and B. C @ D → C sister of D, so D is son of A and B. D # E → D husband of E. Hence E is wife of D (son of B), so E is daughter-in-law of B.
