in fact.... if the parcels are also not distinct, there is only one option:
one parcel with 2 kiwis (+ 3 banans) and the other 1 kiwi (+4 bananas)...
If you can, please try and use the:
total outcome - unfavorable outcome(s) approach
it is not good, in my opinion, to try "forcing" the use of a method to a certain question. it is usually a sign that you try to master, or understand one methodology, and treat it as a "one method for all".
it is never the case in math. there is no "one best method" or "one fits all" technique. there is a wide range of them, and each maybe applied to a different set of questions.
in fact, i would claim, that the different methods are relatively easy to grasp and use, whats difficult is choosing the best one for a given question.
to practice that - the one thing that you don't want is to force a certain method on the given question. what you need is a diverse set of questions, and a lot of patience in analyzing the questions.
not only to understand how the method worked for this question (what most people do when reading OEs) but rather find what in the question implied or invited the use of this method. what "hidden signals" are there that can help you go the short and easy path to the answer.... looking for these signs is the true studying of the GMAT math (my opinion only....)
