Why is there a math question in my Verbal section?

by wishkaro » Tue Jun 09, 2009 1:37 am
Inference question based on numbers

In 2008, Gotsland used three-times as much energy from non-renewable sources as renewable sources. Gotsland's proposed ten-year energy plan would result in the country using as much renewable as non-renewable energy by 2018, while using a larger amount of energy than in 2008.
Which of the following must happen for Gotsland's plan to work?


A. By 2018, Gotsland will more than triple its use of energy sources.
B. Gotsland will have to make a political effort to have a more sustainable energy economy.
C. By 2018, Gotsland will have to decrease its reliance on non-renewable energy sources.
D. By 2018, Gotsland will more than triple its use of renewable energy sources over 2008 levels.
E. New technologies must be developed to make the cost of renewable resources more competitive with renewables.


Note: Some inference questions (like the above) use basic number line analysis or proportions. This is just testing your ability to use numbers in the context of critical reasoning.

IMO D. The question is a good one. With a little logic we can arrive at the right answer. Thanks for posting this question.

I don't get why its D. Suppose we use the following numbers in 2008. Total energy = 100 -> Energy from NR = 75, Energy from R = 25.

No suppose in 2018 the the total energy goes to 120 -> then NR = 60 and R = 60 --> A and D are out then.

B and E are out of scope. So we are left with C.

Am I way off in interpreting the question?

Interesting MGMAT(?) Q

i did it this way

initially i tht its C but now i feel D is best among the rest

ABE are completely OUT


check this

2008--> X ----------3X------------4X

2018--> Y-----------Y-------------2Y

Given that 2Y>4X
hence Y>2X

Now, Y could be 2X,3X,4X....even 2.1X

above 3X there is no issue

as D is saying

D. By 2018, Gotsland will more than triple its use of renewable energy sources over 2008 levels.

Explanation: In questions like these where they start throwing around numbers and you scratch your head…"didn't I already do the quant section?". It might help to use a little Plug In.

In a quant math problem we would translate words to numbers, so let's do that here. In 2008, Gotsland used three-times as much energy from non-renewable sources as renewable sources. Well, we can substitute 50 megawatts of renewable energy and 150 megawatts of non-renewable for what we have in 2008 (total of 200 megawatts).

Looking at the next statement Gotsland's proposed ten-year energy plan would result in the country using as much renewable as non-renewable energy by 2018, while using a larger amount of energy than in 2008. Well, this means that in 2018 they will be using more than 200 megawatts AND renewables will be at least 150 (what the current non-renewables are). So it needs to triple its use of renewables.

Now that we have our facts laid out we can review the answer choices.

1. Gotsland does not need to triple its energy sources (just renewables).
2. Isn't relevant.
3. Gotsland doesn't need to decrease its use of non-renewables. It is mathematically possible for it to increase the total usage of total energy. In this scenario, non-renewables remains at 150 and renewables increases to 150 as well.
4. Yes, Gotsland MUST at least triple its use of non-renewables (to be at least 150 megawatts).
5. This may be the case, but there is nothing in the question to make this point.
