Hello, I'm having trouble understanding why the answer to this question is C.Hungary, perhaps I am understanding the question wrong, could you please explain the rationale?
Q 3.2.2: What was the country with the highest relative increase between 2007 and 2008?
Answer choices:
A. Poland / B. Czech Republic / C. Hungary / D. Bulgaria / E. Cannot answer
I thought the answer was B.Czech Republic because from 2007 to 2008, the increase in percentage point was the largest (10.7 - 8.7 = 2.0%).
Hello Joo,
Please notice that when you talk about "relative increase" you have to divide the delta (new value - old value) by the original value.
For example, in the case of the Czech Republic:
( 2008UR - 2007UR ) / 2007UR = (10.7% - 8.7%) / 8.7% = 23%
Anyway you are right, the correct answer is B because for Hungary you have:
(11% - 9.7%) / 9.7% = 13%
Hope it helps,
Luca
Hi,
I confirm it's an error, but it's crucial that you fix this formula well explained by Luca for your case resolutions.
Best,

For sure, I understand the error in my working and marked a star on it. Thank you Antonello :)
Hello!
You are falling into a classical trap -don´t worry, it´s super normal, particularly when you look at the graph!
If we were taking only about growth, the winner would be clearly Czech Rep -it can be easily seen in the pic, it´s the one whose slope is steepest-.
However, the trick is that they are asking for RELATIVE increase, so you have to divide the delta (new value - old value) by the original value.
Hope it helps!
Cheers,
Clara

Thank you, it helped a lot :) Now I am certain there is an error in the answers page in the mock test.
Thank you for the clear explanation! :)
