Question : The given bar graph shows the number of students of two schools over 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?
Option 1: 429 : 799
Option 2: 429 : 370
Option 3: 799 : 429
Option 4: 370 : 429
Correct Answer: 429 : 370
Solution : According to the question, Average number of students in A $=\frac{640 + 800 + 500 + 700 + 900 + 750}{6}=\frac{4290}{6}$ Average number of students in B $=\frac{550 + 820 + 600 + 750 + 500 + 480}{6}=\frac{3700}{6}$ ⇒ Required ratio = $\frac{\frac{4290}{6} }{\frac{3700}{6}}$ = $\frac{429}{370}$ Hence, the correct answer is 429 : 370.
