The correct answer is cognitive dissonance.
Cognitive dissonance (CD) refers to a state or situation in which a person experiences feelings of discomfort that results from holding two contradictory thoughts, attitudes or beliefs. An instance of cognitive dissonance is the feeling a long-term smoker experiences when he reads an article about an increasing number of deaths due to lung cancer which is heavily caused by smoking.
Ratio:
3 boys / 5 girls
total = 8 people
5 girls / 8 people
Proportion:
5 girls / 8 people = x girls / 40 people
8x = 200
x = 25 girls
40 - 25 = 15 boys
25 - 15 = 10 more girls than boys
There are 10 more girls than boys in the class.
Hope this helps!! :)
