Nope. That's not right! I came to the same conclusion in my first attempt.truplayer256 wrote:If the population of the turtles at Bugle Bay ten years ago was 50,000, then the population of the turtles at Bugle Bay to this very day would be 50,000*3.5 or 175,000. We are told that 2 years ago, the population of the turtles at Bugle Bay was 100,000. In order to find the percent increase of the population of turtles at Bugle Bay over the last 2 years, we do the following:
(175,000-100,000)/100,000*100=75% A.
250% of 50,000 = 125,000 Nowkanha81 wrote:Over the last 10 years ago the turtle population of Bugle Bay has increased 250%. If 10 years ago, there were 50,000 turtles, and 2 years ago there were 100,000 turtles, by what percent did the Bugle Bay turtle population increase over the last 2 years?
A) 75%
B) 66%
C) 50%
D) 33%
E) 25%
The questions says a 250% increase.250% of 50,000 = 125,000 Now
125,000-100,000 (2 years ago) = 25,000 / 100,000 = 25% (E)
OOPS then the answer is A. The OA must be wrong.truplayer256 wrote:The questions says a 250% increase.250% of 50,000 = 125,000 Now
125,000-100,000 (2 years ago) = 25,000 / 100,000 = 25% (E)
Yupe. The OA is not what you think it is. I will post the answer soon..Waiting for others to respondtruplayer256 wrote:I don't know any other way to approach the question then. Are you sure there isn't a mistake in the OA?
Here's the OE solution.blackarrow wrote:I am also getting A
75%
Unless their is some wierd trick involved, The question appears pretty straightforward!
"Increased 250%" definitely means "increased by 250%". The explanation and official answer are just wrong.ssmiles08 wrote:I guess what they mean when they say Bugle Bay has increased 250% is the total increase and not increased by 250%
I hate tricky wordings like these :!:
If we accept the "official" explanation for this question, then an "increase" of 50% would actually mean a decrease to 50% - that certainly doesn't make sense.Over the last 10 years ago the turtle population of Bugle Bay has increased 50%.
What's the source? Please post the source for all of your questions, so we know if the question is reliable - a lot of questions available for free are worth exactly what you paid for them - nothing.Over the last 10 years ago the turtle population of Bugle Bay has increased to 250% of what it was 10 years ago.

To illustrate, let's change 250% to 50%, so our question now reads:If we accept the "official" explanation for this question, then an "increase" of 50% would actually mean a decrease to 50% - that certainly doesn't make sense.Over the last 10 years ago the turtle population of Bugle Bay has increased 50%.
In order for the explanation to be correct, the question would have to read:

Please post the source for all of your questions, so we know if the question is reliable - a lot of questions available for free are worth exactly what you paid for them - nothing.Over the last 10 years ago the turtle population of Bugle Bay has increased to 250% of what it was 10 years ago.

Unless their is some wierd trick involved, The question appears pretty straightforward!
Let N0: original size of pop.
N2: size of population 2 years ago
N10: size of population 10 years ago
Given:
N0 / N10 = 250/100 = 2.5
N10 = 50,000
N2 = 100,000
N0 = 2.5 * N10 = 2.5 * 50,000 = 125, 000
N0 / N2 = 125,000/100,000 = 1.25
Therefore, increase in population is 25%
