Distribution (degree wise) of students in five schools A, B, C, D and E
Total number of students (boys and girls) in 5 schools = 5400
Question 77
What is the ratio of the total number of boys in schools B and D to the total number of girls in schools A and C?
Solution
Number of Students in School A = 44/360 * 5400 = 660.
Girls in School A = 660 - 220 = 440.
Number of Students in School C = 960.
Girls in School C = 960 - 440 = 520.
Total girls in Schools A and C = 440 +Â 520 = 960.
Total Boys in Schools B and D = 830 +Â 450 = 1280.
Required Ratio = 1280 : 960 = 4 : 3.
