Statements:
A. Rupali is older than Pankaj.
B. Sonali is older than Rupali.
C. Tinu is youngest among all.
Choose the correct answer from the options given below to answer the above question:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → B only
The question already gives two facts: Sonali is older than Pankaj, and Rupali is older than Tinu. So the oldest is either Sonali or Rupali; a statement is enough only if it settles which of these two is older.
B. Sonali is older than Rupali. Enough on its own. Then Sonali > Rupali > Tinu, and Sonali > Pankaj, so Sonali is the oldest.
A. Rupali is older than Pankaj. Not enough. Both Sonali and Rupali are then older than Pankaj, but which of the two is older is still not known.
C. Tinu is youngest among all. Not enough. It says who is youngest, not whether Sonali or Rupali is the oldest.
Since B alone answers the question, A is not needed with it.
