Ananya and Krishna can speak and follow English Bulbul can write and speak Hindi as Archana does Archana talks with Ananya also in Bengali. Krishna cannot Bengali, Bulbul talks with Ananya in Hindi. Who can speak and follow English, Hindi and Bengali ?

Work through the statements one by one. Ananya and Krishna both speak and follow English, so English is settled for Ananya. Bulbul speaks with Ananya in Hindi, so Ananya follows Hindi. Archana talks with Ananya in Bengali, so Ananya speaks and follows Bengali too. Ananya is the only person who fits all three.

Why the others fail:

• Krishna is explicitly stated to be unable to speak Bengali, so he is out at once.
• Bulbul speaks and writes Hindi, but nothing says Bulbul knows Bengali or English.
• Archana is linked to Hindi and Bengali, but the statements never say she can speak or follow English.

Core concept: this is a linear-reasoning puzzle in which you must use only the facts given and avoid assuming anything beyond them. The same discipline helps in Mains answers, where unsupported inference costs marks.

Trap: aspirants assume Archana must know English because she is connected to other languages, or they read "talks with" as one-sided knowledge. A conversation requires both parties to understand the language, so each "talks with" statement proves the knowledge of both people involved.
