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? Correct Answer 429 ∶ 370

Calculation:

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

∴ The required ratio is 429 : 370
