Seven people of a family P1, P2, P3, P4, P5, P6 & P7 go on a picnic in a sports utility vehicle. P4 is the sister of P7, P2 is the mother of P6’s wife. P6 is the son-in-law of P3. P5 and P7 are the grandsons of P3. Two people in that group of 7 are fathers; two are brothers; and two are mothers; and one is a sister. What is the relationship between P1 and P4?
Explanation
To determine the relationship between P1 and P4 based on the data in image_809b02.png, we analyze the family structure:
Generation 1: P3 is the head of the family. Since P6 is the son-in-law of P3 and P5/P7 are grandsons of P3, we can establish the hierarchy.
Family Links:
P2 is the mother of P6's wife.
P6 is the son-in-law of P3, which implies P3 is the parent of P6's wife.
Since P4 is the sister of P7 and they are grandchildren of P3, they belong to the third generation.
Identifying P1: With P2 identified as the mother of the wife and P3 as a parent, P1 represents the remaining parent/member who fits the role of mother to P4.
Given the family roles defined (2 fathers, 2 mothers, 2 brothers, 1 sister), the logical deduction for the relationship between P1 and P4 is Mother - Daughter.
Correct Answer: Option 1
