  • A. 370 : 429
  • B. 429 : 799
  • C. 799 : 429
  • D. 429 : 370
Correct Answer: Option D - From the given bar graph Total number of students in school A = 640 + 800 + 500 + 700 + 900 + 750 = 4,290 Total number of students in school B = 550 + 820 + 600 + 750 + 500 + 480 = 3,700 Hence, the ratio of the average number of students in school A and B = 4290/6 : 3700/6 Hence A : B = 429 : 370
D. From the given bar graph Total number of students in school A = 640 + 800 + 500 + 700 + 900 + 750 = 4,290 Total number of students in school B = 550 + 820 + 600 + 750 + 500 + 480 = 3,700 Hence, the ratio of the average number of students in school A and B = 4290/6 : 3700/6 Hence A : B = 429 : 370

Explanations:

From the given bar graph Total number of students in school A = 640 + 800 + 500 + 700 + 900 + 750 = 4,290 Total number of students in school B = 550 + 820 + 600 + 750 + 500 + 480 = 3,700 Hence, the ratio of the average number of students in school A and B = 4290/6 : 3700/6 Hence A : B = 429 : 370
