Looking at the portrait of a man, Lucky (male) said, "This person is the only child of my paternal grandmother’s daughter." Whose portrait was Lucky looking at?
Step-by-step Solution:
“Paternal grandmother’s daughter” = Lucky’s father’s mother’s daughter ⇒ Lucky’s paternal aunt (not his mother).
The man is the only child of Lucky’s paternal aunt ⇒ her son.
The son of one’s aunt is one’s cousin.
Final Answer: His cousin.
