What is the maximum balance that may be held in a small account opened without any officially valid document?

The correct answer is C, rupees fifty thousand. A small account is opened for a person who has no officially valid document, on the strength of a self-attested photograph and a signature or thumb impression made before a bank officer. Because identification is weak, the account carries three limits: the balance at any time may not exceed fifty thousand rupees, the total credits in a financial year may not exceed one lakh rupees, and withdrawals and transfers together may not exceed ten thousand rupees in a month.

Option A, ten thousand rupees, is the monthly withdrawal ceiling and not the balance limit. Option B is not a limit in the rules. Option D, one lakh rupees, is the annual credit ceiling. The three figures belong together, so the safe way to answer is to remember them as a set: fifty thousand balance, one lakh a year, ten thousand a month, valid for twelve months in the first instance.
