I'm sorry but it is just so fully beyond me how it is even humanely possible to do well in the Quantitative reasoning section of the UCAT. I am bewildered at those who can read, comprehend, calculate and answer a question in as little as 30 SECONDS!!!
Anyway, that wasn't the point of this post, I do have an actual question about quantitative reasoning. I just did a test and I can't understand why I got this question wrong:
"In a population, 8% can taste
neither PTC nor sodium benzoate,
74% can taste PTC and 60% can
taste sodium benzoate. What
percentage can taste exactly one
of these two chemicals?"
My answer (which mind you required MORE than just 30 seconds to even understand the question) was 42% but the answer is 50%! like how??!!
The solution says to do this calculation required: 74 − x + 60 − x + 8 + x
= 100, x = 42, 32 + 1
their solution clearly states that x=42 but I have no idea what that (32+1) part is for, like hello UCAT mind being a little more clearer with your solutions?!! DAMN! is it 50% or 42% can someone please help me understand why I am wrong and why the solution says (x=42, 32 + 1) ???
Thank you so much!
and also, would really appreciate it if anyone can tell me how they are coping with the QR section, is it just me or does anyone else hate this section. I'm starting to think it's just me and everyone else doing this test is just somehow super fast mathematicians.
