The total number of students in all colleges together is 60000 and the total number of girls is 24000. The student percentages are A 10, B 9, C 23, D 18, E 16 and F 24. The girl percentages are A 15, B 12, C 18, D 14, E 20 and F 21. Based on the data, answer the questions.
The ratio of the number of boys in College F to the number of boys in College D is
A31:39
B39:31 ✓ Correct
C39:37
D37:29
Correct answer: (B) 39:31 — The answer is 39 to 31.
Explanation
★The answer is 39 to 31.
★College F has 24 percent of 60000 students, which is 14400, and its girls are 5040, so its boys are 9360.
★College D has 10800 students and 3360 girls, so its boys are 7440.
★So the ratio is 9360 to 7440.
★Dividing both by 240 gives 39 to 31.
★So the ratio simplifies to 39 to 31.
★So the answer is 39 to 31.
