A group of D, P, W, Y and M are travelling together. W is travelling with his daughters D and P. M is travelling with his grandmother Y. D is the mother of M. How is Y related to P?
A. Grandmother
B. Sister
C. Daughter
D. Mother
Answer: Option D
Solution (By JKSSB Mock Tests)
D and P are daughters of W. Since Y is M's grandmother and D is M's mother, Y is D's mother. Therefore, Y is also P's mother.
If 'M = N' means 'M is the father of N', 'M # N' means 'M is the son of N's sister', 'M × 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.
Explanation:
A brother of C → A male. B father of C → B father of A and C. D wife of A → D is A's wife. E daughter of D → E is daughter of A and D. A is son of B, so E is granddaughter of B, i.e., son's daughter.
Explanation:
The only child of Reena's grandfather is Reena's parent (father or mother). The only son of Reena's parent is Reena's brother. Thus, Reena is the sister of the boy.
