- $10$
- $30$
- $20$
- $40$
Show answer and solution
Correct answer: C. $20$
|tea ∪ coffee| = 60 + 50 − 30 = 80. Neither = 100 − 80 = 20.
A says: 'B is my father's only daughter.' Who is B to A?
- A's mother is the reference
- A's sister is the reference person
- A's grandmother by marriage
- A's first cousin from her father side
Show answer and solution
Correct answer: B. A's sister is the reference person
'My father's only daughter' = the speaker (if A is a girl) or A's sister (if A is a boy).
B is the speaker's sister, or A herself if A is female.
