-Let's assume there are 100 cars. We have the following deductions:
1) 80 are German, 20 are non German
2) 40 are higher than 100k, 60 are lower than 100k
3) 35 are higher than 100k and are German
-From (2) and (3)=> 5 are higher than 100k and are non-German (4)
-From (1) and (4)=>15 are lower than 100k and are non German.
-The question asks  "what percent of cars priced under 100k are not German" =>The numerator is   15   and the denominator is   60  
=>The percentage=  \frac{15}{60}=25% 
 The answer is D

Given: In a certain car dealership, 80 percent of all cars are German, and 40 percent of all cars are priced at $100,000 or more. 
Asked: If 35 percent of cars are priced at $100,000 or more and are German, what percent of cars priced under $100,000 are not German?

German  Not German  Total  
  Priced at $100,000 or more  35%  40%-35%=5%  40%  
  Priced under $100,000  80%-35%=45%  60%-45%=15%  60%  
  Total  80%  20%  100%

The percent of cars priced under $100,000 are not German = 15%/60% * 100% = 25%

IMO D

solve using 2x2 matrix
let total cars be 100

Let's use the double matrix method here. We know that 80% of all cars are German, and 40% of all cars are priced at $100,000 or more. For simplicity, let's assume that the total number of cars is 100 Now, as per the given statement, we can draw this table. (I was not aware that I could create neat tables in the answer until today. So I tried that here.

) The matrix: Total cars = 100 German Cars Non German Cars Total $100k or more 35 ? 40 Less than $100k ? ? ? Total 80 ? 100 Now let's complete the matrix: Total cars = 100 German Cars Non German Cars Total $100k or more 35 5 40 less than $100k 45 15 60 Total 80 20 100 We are asked to find the percentage of cars priced under $100,000 that are not German. There are 60 cars priced under $100,000 in total (in bold), 15 of which are not German. So, the percentage of cars priced under $100,000 that are not German is (15/60) x 100% = 25%. I will go with D.

We have: 11.jpg Assuming total cars as 100, we have: 80 are German, so 20 are non-German 40 are priced at $100,000 or more, so 60 are priced less than $100,000 35 are German and priced at $100,000 or more So 40 - 35 = 5 are non-German and priced at $100,000 or more Also 80 - 35 = 45 are German and and priced at less than $100,000 And 60 - 45 = 15 are non-German and and priced at less than $100,000 Number of cars priced less than $100,000 = 60 Number of non-German cars among these 60 = 15 Required percent = 15/60 * 100 = 25% Answer D
