The given bar graph shows the number of students of two schools over a period of six years.
In the bar graph, what is the ratio of the average of the total students from school A to the average of the total students from school B?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 429 : 370
Total number of students from school A = 640 + 800 + 500 + 700 + 900 + 750 = 4290
Total number of students from school B = 550 + 820 + 600 + 750 + 500 + 480 = 3700
Ratio of average of total students from school A to school B = (4290/6) : (3700/6) = 4290 : 3700 = 429 : 370
