140 students owned iPhones; of these 50 also owned cars; 140 - 50 = 90

90 students own only an iphone

60 owned cars; of these 50 also own a car; 60-50 = 10; 10 students own ONLY a car

The number of student who own either a car or an iphone, but not both is 90 + 10 = 100

The number of students who do not own either a car or an iphone is 200 - 50 - 10 - 90 = 50 students
