The given histogram shows average percentage score of boys and girls in an examination during the years 2014 – 2018.
What is the ratio of the absolute difference in percentage scores of boys and girls in 2014 as compared to the absolute difference in their percentage scores in 2018?
Given:
Histogram shows average percentage score of boys and girls in an examination during the years 2014 – 2018.
Solution:
In 2014:
Boys' score = 65
Girls' score = 60
Absolute difference = 65 − 60 = 5
In 2018:
Boys' score = 60
Girls' score = 80
Absolute difference = 80 − 60=20
The ratio of the absolute differences is:
Ratio: =
The ratio is 1:4.
Thus, correct answer is (a) 1: 4
