Study the given pie chart and answer the question that follows.
Break-up (degree-wise) of the number of students in five schools (A, B, C, D and E) in a city.
Total number of students = 5200
If the ratio of the number of boys to that of girls in school B is 7 : 6 and the ratio of the number of boys to that of girls in school is 4 : 5, then what is the ratio of the number of boys in B to that of girls in D?
Answer & explanation
Correct answer: option 1
Number of boys in school B = \(\frac{7}{13}\) × \(\frac{72}{360}\) × 5200
= 560
Number of girls in school D = \(\frac{5}{9}\) × \(\frac{64.8}{360}\) × 5200
= 520
Now , Number of boys in school B : Number of girls in school D
= 560 : 520
= 14 : 13
