OG Problem #107

Last year all refuse collected by Shelbyville city services was incinerated. This incineration generated a large quantity of residual ash. In order to reduce the amount of residual ash Shelbyville generates this year to half of last year's total, the city has revamped its collection program. This y...

This question represents the harder subclass of assumption questions: the ones where the assumption is not just a link between the premises and the conclusion, but rather a necessary step: the position is that you CANNOT reach the conlcusion WITHOUT assuming C. The question you need to ask yourself...

If 3 liters of water are added to Maria's bucket when it is half full of water, the amount of water in the bucket will increase by (1/3). Marcia's bucket can hold a maximum of how many liters of water? 18 liters of water I initially approached it using the following equation. What is my incorrect e...

@Adam I couldn't agree with you more! Very insightful analysis. The questions on the RC are not designed to test you on semantics but on your analytical ability. Probably the passages on the LSAT maybe more about semantics(that's what the lawyers are expected to :-D) but certainly not those you see...

Well, I'd say MGMAT's math books are about 100x better than any official guide books. Referring to your last statement... I'm just testing what others think about RC99 and not dismissing it all together (yet). Funny, it reminds me of a book titled: "Mom, get out of my life, but can you first dr...

Let's be carefully on what we consider "easy". To me, reading music is easy, but that's because I've been doing a lot of it. RC may be easy to you since you've been practicing on how to answer RC questions. It's all relative. The "reading" itself might have been easy since it's a...

RC99 Passage 25

Georges LeClerc (1707-1788) proposed a mechanism for calculating the age of the Earth using molten spheres of iron and measuring cooling times, after which he proposed that the Earth was at least 75,000 years old and perhaps as old as three million years. Some students may feel that we should not fo...

OA is D. Solution: To make the calculations easier, let's assume that there are 100 students in the lecture (100 is usually a good number for percent problems without concrete numbers). Of those 100 students, 30 are finance majors and 40 are female. Of the 70 non-finance majors, we know that 60 per...
