He bought boxes _____ the rate of fifty rupees a piece.

• A. by
• B. at

Answer 1

The correct option is B at

A preposition is a word which comes before a noun or a pronoun and establishes a relationship between the elements of a clause or words. Option B)at is correct as it indicates an amount. The other options are wrong as by, with, and on indicate usage, inclusion, and a surface respectively. These uses don't fit in the given question. The correct answer is B)at.
