Official Explanation
Solution: A – With this percent change problem, note that the current “total” can be set to 100 because a pie chart must add up to 100%. Doubling Italy adds 2.3 to that total and halving Germany subtracts 1.4, netting out a .9 increase. And since we started with 100, this represents an approximately 1% increase.
Solution: B – Here, divide the 25.3 percent by the 120 countries there – using relative math, that’s about 1/5 of one percent for each country. And the United States makes up about 43 percent. And since 1/5 out of 43 is approximately 1 out of 200, that means that the answer is 0.5%.
A. increase by 1%
B. 0.5

Hey Sajjad1994, could you share the official explanation for the second question.
I would love to know the calculations as I just guessed the answer and it turned out to be right.
