Question

If Golu is son of Molu, Molu and Polu are sisters, Pillu is Polu's mother, Gannu is son of Pillu, which of the following statements is definitely true?

• A. Golu and Gannu are cousins
• B. Golu's nephew is Gannu
• C. Golu's maternal uncle is Gannu
• D. None of the option is correct

Answer 1

The Correct Option is C

To solve the problem, we must analyze the family relationships described:

• Golu is the son of Molu.
• Molu and Polu are sisters. This implies that they share the same mother.
• Pillu is the mother of Polu. This means Pillu is also the mother of Molu. Therefore, Pillu is the grandmother of Golu.
• Gannu is the son of Pillu, making Gannu the brother of both Molu and Polu, since Pillu is their mother.

Now let's evaluate the statements:

• Golu and Gannu are cousins: This is not possible because Golu is the nephew of Gannu.
• Golu's nephew is Gannu: This is incorrect because Golu is younger than Gannu, and Gannu is Golu's uncle.
• Golu's maternal uncle is Gannu: This is correct because Gannu, being the brother of Molu (Golu's mother), is indeed Golu's maternal uncle.
• None of the option is correct: This is incorrect because the third option is true.

Hence, the statement that is definitely true is:

Golu's maternal uncle is Gannu.

Answer 2

This problem is easiest to solve by assigning each person to a generation level, since the relationships given are all about parents, children and siblings.

Pillu is the mother of Polu, and Polu and Molu are sisters, so Pillu is also the mother of Molu; that makes Pillu one generation above both Molu and Polu. Golu is the son of Molu, so Golu sits one generation below Molu, that is, two generations below Pillu. Gannu is the son of Pillu, which places Gannu in the same generation as Molu and Polu, one generation above Golu, and makes Gannu the brother of Molu and Polu.

1. Option A (Golu and Gannu are cousins): Cousins belong to the same generation, but Golu is one generation below Gannu, so this is incorrect.
2. Option B (Golu's nephew is Gannu): A nephew is younger and in the generation below oneself; Gannu is older and one generation above Golu, so this relation is reversed and incorrect.
3. Option C (Golu's maternal uncle is Gannu): Gannu is Molu's brother, and Molu is Golu's mother, so Gannu is exactly Golu's maternal uncle, making this correct.
4. Option D (None of the option is correct): Since option C holds true, this option is incorrect.

Since Gannu is the brother of Golu's mother Molu, Gannu is Golu's maternal uncle.

the correct answer is Option C: Golu's maternal uncle is Gannu.
