QTY A = K/J which basically could be any Number greater than 1
QTY B = K+10/J+10 which remains a number > 1. However it will become a smaller fraction. For instance (4/3) > (14/13).
Therefore A must be the answer.

Explanation

Plug in numbers and use the rate formula—amount = rate × time—to check the quantities. If j = 1 and k = 2, then Quantity A is 2 minutes and Quantity B is \(\frac{20}{11}\) minutes.

Quantity A is greater, so eliminate choices (B) and (C). Any acceptable set of values gives the same outcome; select choice A.
