Last week... CR week

Whole of last week was dedicated to ..err... office. :) As per plan, i was supposed to finish CR basics.

What i learnt
1. Read the passage carefully word by word since every word is important.
2. Read the question before reading the passage. This would give you an idea what to expect.

Areas of improvement

1. Some of the CR questions i didnot understand at all. So, i chose the wrong answer.
2. I go wrong especially when the question involve words like EXCEPT and LEAST i.e they provide a twist at the last word. I don't read this word inspite the word being in caps. So, a strengthen or weakening questions, it would be like which among the five, strengthen the argument the LEAST. I see the word strengthen and off i go.
3. When i choose a wrong answer for a question, in all probability the next answer will also be wrong. This clearly proves that i have high concentration for few minutes and low concentration for few minutes. Need to work on concentration more before it is too late.

A Teaser (atleast for me)
An empty metal box weighs 10 percent of its total weight when filled with varnish. If the weight of a partly filled box is one-half that of a completely filled box, what fraction of the box is filled?
The calculation for this problem is very easy but i didn't understand what this question is all about. I would have understood the question had they rephrased the question better. Something like........
