Question

Vishnu told Radha,'Your mother is the daughter of my grandmother.' How are Vishnu and Radha related?

• A. Cousins
• B. Uncle-Niece
• C. Father-Daughter
• D. Grandfather-Granddaughter

Hint:

The daughter of a grandmother is your mother or aunt. Her child is your sibling or cousin.

Answer 1

The Correct Option is A

Step 1: Concept
We can draw a small family tree in words. The top person is the grandmother. Her children sit on the next line, and their children sit on the line below.

Step 2: Build the tree
Vishnu's grandmother is G. Her children include Vishnu's parent P and another daughter D. D is Radha's mother.
So Radha (child of D) and Vishnu (child of P) both sit on the third line of the tree.

Step 3: Read the relation
Two people on the same line whose parents are brother and sister, or two sisters, are cousins. So Vishnu and Radha are cousins.

Step 4: Why not the other options
Uncle-Niece and Father-Daughter would put the two people on different lines. Grandfather-Granddaughter would put them two lines apart. None of these fits, because both are grandchildren of G.

Final Answer:
They are cousins, option 1. \[ \boxed{\text{Cousins}} \]
