Pointing to a lady, Juhi said, 'She is the daughter of the only son of my grandfather.' How is Juhi related to that lady?
A. Aunt
B. Sister
C. Daughter
D. Mother
Answer: Option B
Solution (By JKSSB Mock Tests)
Juhi's grandfather's only son is Juhi's father. The lady is the daughter of Juhi's father. Therefore, the lady is Juhi's sister, and Juhi is her sister.
Explanation:
Since the man has no brother or sister, 'my father's son' must be the man himself. The statement simplifies to: 'that man's father is myself'. Therefore, the photograph is of his son.
If 'M = N' means 'M is the father of N', 'M # N' means 'M is the son of N's sister', 'M Ă— N' means 'M is the son of N's husband', 'M & N' means 'M is sister of N', 'M $ N' means 'M is wife of N', 'M @ N' means 'M is the brother of N', then how is A related to C in the following expression? A # L = K & P @ C = B
Explanation:
A # L → A is son of L's sister, so A's mother is L's sister. L = K → L is father of K. K & P → K sister of P. P @ C → P brother of C. So K, P, C are siblings, all children of L. Thus L is father of C. A's mother is L's sister, making A and C cousins.
