Thanks Walker ... I understood the explanation.

One question though..... For instance , in this question 28% liked coffee and tea. Does this mean that 28 % liked ONLY coffee and tea ?

I am assuming that since 28 % liked coffee and tea and some % (say x%) like all three things ( coffee, tea and smoke), then to get ONLY coffee and tea % we have to subtract x% from 28 % .Then to get ONLY coffee % , we have to subtract (28 - x) from 48 %.

I have solved couple of questions in which similar statements were given and I had to subtract in the way I mentioned to get the correct answer.

I think "like coffee and tea" doesn't mean only coffee and tee.

48% - coffee (28% - x%) - only coffee and tee (30% - x%) - only coffee and smoke x% - coffee, tea and smoke

only coffee = coffee - only coffee and tee - only coffee and smoke - coffee, tea and smoke

Hey...I got it now.

Thanks a lot Walker... Appreciate your help.

I am trying to finish quant since I have 2 weeks off from work. Will trouble you guys again if I have any doubts.

Please bare !!

Any advice on how to approach RC. To be honest, I am very weak in RC and whenever I try to start it, I either loose focus or something comes up to take me away from it. In my opinion, you just cannot rely on SC and CR. In order to get a decent verbal score, you must get your RC questions right.(not all, but a fair percentage so to speak).

I have read few RC posts on this forum in which writing notes of ONLY first paragraph and then taking key words from the rest of them is one of the strategy employed. Is this the way I should approach RC ?

There is a lot of thoughts about the best RC strategy. I've improved my RC success rate dramatically just by reading slowly with huge interest and solving SC faster to have enough time for RC.

From the V.Diagram I got To calculate ONLY coffee can I add coffe&tea and coffee&smoking substract coffee&tea&smoking and substract it from coffee total(960) ??? ONLY COFFEE 160 ONLY TEA 240 ONLY SMOKING 400
