When correct is incorrect
BBC Bitesize is a series of purportedly educational learning materials and quizzes for children. Or is it? Educational, that is.
This question arose in The most educational Abba quiz in the world - ever. Read it carefully.
Specifically, What was Sweden's winning margin over Italy as a percentage?
Since the winning margin is that of Sweden over Italy, the actual calculation is the six point difference in terms of Italy's score, not Sweden's:
(24 - 18) ÷ 18 × 100 = 33.3%
Therefore, Abba's six-point margin meant they had a 33.3% lead over Cinquetti, not 25%. Note that this answer, which is correct in terms of how the question is worded, is not even one of the options. (rolleyes)
Cinquetti's score was 25% behind Abba's.
