Hi,
I'm really bad when it comes to Data Sufficiency word problems that involve % (increase, decrease, ratio) as well as those have to do with arithmetic mean. I'm talking about the problems I found in Kaplan Advanced book and OG 11 DS problems towards the end, so I believe they are medium-hard to hard problems. Nevertheless, I want to improve my performance on them, what should I do besides besides practicing more of those problems? If the only way is practicing, is there a technique or systematic way of approaching those types of problems so I can be more efficient and effective?
p.s. I hate those problems by nature because they are so long, wordy and pack with bunch of different #'s and relationships/ratios among different variables.
Thanks a lot!
