    Post DATA Sufficiency

    One of the issues with Data Sufficiency questions that i have always faced is that you need background knowledge of the topic....and you are not even sure whether you have it or not......unlike other types of questions where you are able to decide what area it is from.

    Further, i have always found Data Sufficiency to be trickier than other types of questions.....what say?

    DS questions are generally too tough or too easy.

    I left both the questions in CAT 2008, as if felt it would require some efforts, and there were easier questions available.

    So if you feel that the question is too tough, leave it.

    One other trick many people use, is they start with statement B. What that does is, if the question can be answered By 2 alone, you will get it. Generally while doing DS, we tend to mix up what is there in statement A and statement B and hence generally choose option 4, which says can be solved by using both.

    DS is very tricky

    Post DATA Sufficiency

    i think it is more easier than any other type although it require basic knowledge of all the thing but that too its just simple fact .We does not pay attention on such types of question although they are easier than any question and also scoreing so we have to concentrate on it foe scoring well.

    DS q's are definitely tricky coz sometimes they are easier than what we think...it'll be easier 2 tackle them if we take them easy.

    it has to be E...using A you dont know naything about the cost of family size box so you cannot tell its cost per ounce..may be bokk had a printing mistake because the answer has to be E

    AJ.
    answer will be option c..
    in 1st statement nothing is said about price

    in 2nd statement nothing is said about weight

    so options a and b got rejected
    now use both the options..
    you can solve the qs by taking any value for weight and price...let weight be x and price be y or you can also take any numerical value for weight and price to solve the problem in which you feel comfortable...so by using both statements we can answer the question....
    hope that helped..

    In data sufficiency ques, u dont have to calculate the value...and moreover the ques just asks about the box which has more price per ounce, nt the exact price.

    whatever value you will take you will alwayz get price per ounce of cocoa for box A less than B and that is what is asked in question..
