Is the reason rounding up to 161 is not possible because (2.5) x (161) > 401?

With regards to Grouping Problems in the Extra Problem Types Chapter, the book says: "For some problems, may want to think about the most or least evenly distributed arrangement of the items. That is, assign to groups as evenly (or unevenly) as possible to create extreme cases." Can you pr...

Chapter 7: Extra Problem Types (79 / 100 online version) "The guests at a football banquet consumed a total of 401 pounds of food. If no individual guest consumed more than 2.5 pounds of food, what is the minimum number of guests that could have attended the banquet" No answer choices prov...

Can you please explain how you would solve this problem using the RTD chart. When I see rates problem, I try to use the same approach (RTD chart) and couldn't figure out how to apply it to this problem. Thanks.

Ron,

Thank you for your responses. They were very helpful. And to answer your question regarding the book, no problem / example was offered as an illustration.

In the first post, GayaneP973 asked if the statement: "If a Data Sufficiency question asks for the relative value of two pieces of a ratio, ANY statement that gives the relative value of ANY two pieces of the ratio will be sufficient." applied to the problem This question comes from the FD...

The Algebra Strategy guide in Chapter 8 states that one should not make assumptions about sufficiency based on the number of variables and equations in the problem. As discussed in the chapter this is not safe because of combo and mismatch situations, but I was wondering if there is a time (or scena...

Tim,

After reading your previous post, I am still unsure of what your intuition was for choosing 160 versus 161. Can you explain further? Was my reasoning that "161 is not possible because (2.5) x (161) > 401" and therefore does not adhere to the constraints not sound?

Thanks.

Is the conclusion of the argument: "So, even if bacteria did arrive on Earth from Mars, they must have died out."

Whats wrong with answer choice B?

Thanks.

Why is "it" not an issue in the sentence? Is "making it" a special construction that does not require "it" to have an antecedent? Thanks

Stacey, is the list you posted on October 24th, 2013 still current? If not, can you please post an updated list? Thank you!

In the original question posted, is the use of ",which" correct in answer choice A? I thought that the ",which" modifier is referring to moisture, and thus, it should be touching "moisture". Also, can you list the exceptions for which a noun modifier does NOT have to to...

Ron,

Thank you for your response! So is the ",which" the only notable modifier type that we should evaluate strictly to see if it is touching the noun it's modifying? Or are there other notable modifiers that we should pay special attention to as well for this rule?

Thanks!

Thanks Ron!
