Keep in mind that from a person’s name, we cannot judge the gender of that person. The name doesn’t always show the gender beyond a reasonable doubt.
Solved Examples:
Question 1: Pointing to a girl in the photograph, Ajay said, “Her mother’s brother is the only son of my mother’s father.” How is the girl’s mother related to Ajay ?
A) Mother
B) Sister
C) Aunt
D) Grandmother
E) None of these

Solution:
Only son of Ajay’s mother’s father — Ajay’s maternal uncle.
So, the girl’s maternal uncle is Ajay’s maternal uncle.
Thus, the girl’s mother is Ajay’s aunt.
Question 2:
1. A + B means A is the brother of B
2. A × B means A is the father of B
3. A ÷ B means A is the mother of B
Which of the following would mean “G is the son of H”?
A) H × I × G
B) H + G × I
C) H ÷ G ÷ I
D) H × G + I

Solution: Answer: Option D

We don’t know the gender of I. So. We will not put any symbol on its side.
Now that you have understood the topic well and solved the above examples, you are ready to take the test on relations.
