Fresh potatoes generally cost about $2 for a 10-pound bag, [#permalink] ### Show Tags 09 Apr 2010, 22:59 2 This post was BOOKMARKED 00:00 Difficulty: (N/A) Question Stats: 79% (02:40) correct 21% (01:06) wrong based on 135 sessions ### HideShow timer Statistics Fresh potatoes generally cost about$2 for a 10-pound bag, whereas dehydrated instant potatoes cost, on average, about $3 per pound. It can be concluded that some consumers will pay 15 times as much for convenience, since sales of this convenience food continue to rise Which of the following, if true, indicates that there is a major flaw in the argument above? (A) Fresh potatoes bought in convenient 2-pound bags are about$1 a bag, or 2 ½ times more expensive than fresh potatoes bought in 10-pound bags.
(B) Since fresh potatoes are 80 percent water, one pound of dehydrated potatoes is the equivalent of 5 pounds of fresh potatoes
(C) Peeled potatoes in cans are also more expensive than the less convenient fresh potatoes
(D) Retail prices of dehydrated potatoes have declined by 20 percent since 1960 to the current level of about $3 a pound. (E) As a consequence of labor and processing costs, all convenience foods cost more than the basic foods from which they are derived.

Evidence : Fresh potatoes generally cost about$2 for a 10-pound bag, whereas dehydrated instant potatoes cost, on average, about $3 per pound. Conclusion : It can be concluded that some consumers will pay 15 times as much for convenience, since sales of this convenience food continue to rise Inorder to weaken the conclusion, we need to find a statement which states that "Some factor, other than convenience is the reason for consumers to pay 15 times more for dehydrated instant potatoes ." (A) Fresh potatoes bought in convenient 2-pound bags are about$1 a bag, or 2 ½ times more expensive than fresh potatoes bought in 10-pound bags. - It just compares fresh potatoes in convenient 2-pound bags and 10-pound bags !
(B) Since fresh potatoes are 80 percent water, one pound of dehydrated potatoes is the equivalent of 5 pounds of fresh potatoes - It mentions a factor other than convenience... hence it weakens the conclusion
(C) Peeled potatoes in cans are also more expensive than the less convenient fresh potatoes - irrelevant(D) Retail prices of dehydrated potatoes have declined by 20 percent since 1960 to the current level of about $3 a pound. - This will kind of strengthen the argument ! (E) As a consequence of labor and processing costs, all convenience foods cost more than the basic foods from which they are derived. - irrelevant _________________ "Success is going from failure to failure without a loss of enthusiam." - Winston Churchill As vs Like - Check this link : http://www.grammar-quizzes.com/like-as.html.

This means that Prices came down from Rs 3.75 to Rs 3 (20% decline) which implies that people were paying around 18 times and now paying 15 times. This is not much of a difference to affect the buying behaviour of customers. Hence D cannot be the correct option
Thanks,

can someone help me on solving this question via the negation technique?
I got the answer right, but without the negation technique

As mentioned in my reply to your previous post, negation technique is recommended to be used ONLY with assumption questions.
