Statement :1
The fashion show lasted 90 minutes.: no info about coats
Not sufficient
Statement:-2
Ratio of number of model to no of different coats = 1/7
M/C= 1* / 7*
Given M=9
So if x=1 then Coats =63
Sufficient:
B

Given: 9 models participated in a certain fashion show featuring coats
Target question: How many different coats did they model?
Statement 1: The fashion show lasted 90 minutes.
The statement provides new information about the number of coach that were modeled.
Since we cannot answer the target question with certainty, statement 1 is NOT SUFFICIENT
Statement 2: The ratio of the number of models who participated in the show to the number of different coats modeled was 1 to 7
Let x = total number of different coats modeled
We can write: number of models : number of different coats modeled = 1 : 7
Substitute values to get: 9 : x = 1 : 7
In other words: 9/x = 1/7
Solve to get: x = 63
The answer to the target question is 63 different coats were modeled
Since we can answer the target question with certainty, statement 2 is SUFFICIENT
Answer: B
Cheers,
Brent
