Question : The bar graph represents the number of boys and girls in five schools. Study the graph and answer the question that follows.
What is the ratio of girls and boys from all the schools?
Option 1: 59 : 61
Option 2: 66 : 59
Option 3: 59 : 66
Option 4: 61 : 59
Correct Answer: 59 : 66
Solution :
According to the question
Total Boys = 600 + 450 + 750 + 700 + 800 = 3300
Total Girls
= 500 + 550 + 650 + 600 + 650 = 2950
Required ratio = $\frac{\text{total number of girls in all schools}}{\text{total number of boys in all schools}}$
= $\frac{2950}{3300}$ = $\frac{59}{66}$
Hence, the correct answer is 59 : 66.
