Question : The given bar graph represents the number of boys and girls in five different schools. Read the graph and answer the question that follows.
What is the ratio of the girls from schools A, B, and C taken together to the boys from all schools taken together?
Option 1: 33 : 17
Option 2: 17 : 33
Option 3: 66 : 59
Option 4: 59 : 66
Correct Answer: 17 : 33
Solution :
Total number of girls from A, B, and C = 500 + 550 + 650 = 1700
Total number of boys from all school = 600 + 450 + 750 + 700 + 800
= 3300
= $\frac{1700}{3300} = \frac{17}{33}$
$\therefore$ The required ratio is 17 ∶ 33
Hence the correct answer is 17 ∶ 33.
