customers rating negative ; 30+45-x ; 75-x
x = both
#1
The number of customers who did not rate either product or service "Negative" was 40.
total 100 so 100-40 ; 60 is both
75-60 ; 15 sufficient
#2
The number of customers who rated both product and service "Positive" was 30.insufficient
IMO A

Let the number of customers who rated both the company's product and its service negatively be x

30 + 45 - x = 75 - x = Number of customers who rated either product or service "Negative"

(1) The number of customers who did not rate either product or service "Negative" was 40.
75 - x = 100 - 40 = 60
x = 15
SUFFICIENT

(2) The number of customers who rated both product and service "Positive" was 30.
NOT SUFFICIENT

IMO A
