Answer:
b) 15
Step-by-step explanation:
Given that,
Total people = 100
% of people prefer vanilla = 25%
Number of people prefer vanilla out of 100 = 25% of 100
=> 25/100 * 100 = 25
% of people prefer swirl = 35%
Number of people prefer swirl out of 100 = 35% of 100
=> 35/100 * 100 = 35
% of people prefer chocolate = 40%
Number of people prefer chocolate out of 100 = 40% of 100
=> 40/100 * 100 = 40
The number of more people preferring chocolate over vanilla = 40 - 25
=> 15 so option b is correct
