Show answer & explanation
Correct answer: D
To find the ratio of the number of students who appeared in School A to those who appeared in School B, we need to extract the values from the bar graph.
Step-by-Step Analysis
Extract Data for School A: Look at the "Appeared" bar (the dotted bar) for School A. The height of this bar aligns with the 3000 mark on the Y-axis.
Extract Data for School B: Look at the "Appeared" bar (the dotted bar) for School B. The height of this bar aligns with the 2250 mark on the Y-axis.
Calculate the Ratio:
Ratio = (Appeared in School A) / (Appeared in School B)
Ratio = 3000 / 2250
To simplify, divide both by their greatest common divisor, which is 750:
3000 / 750 = 4
2250 / 750 = 3
The ratio is 4:3.
