The following table shows the number of employees working in five different colleges A to E, along with the ratio of Males to Females (M:F) among them. Based on the data in the table, answer the questions that follow.
College A: 3040 employees, ratio 13:6.
College B: 3360 employees, ratio 4:3.
College C: 2920 employees, ratio 9:11.
College D: 2760 employees, ratio 10:13.
College E: 2840 employees, ratio 13:7.
What is the ratio of the number of boys of school C who scored between 90-95% marks to the number of boys who scored 95% and above marks in the same school?
A5 : 9
B10 : 17 ✓ Correct
C10 : 13
D12 : 17
Correct answer: (B) 10 : 17 — The required ratio for school C is 10 to 17.
Explanation
★The required ratio for school C is 10 to 17.
★Boys of C scoring 90-95% are 10 percent of 10000 times 3 over 8.
★This gives 1000 times 3, that is 3000 over 8 as the raw value.
★Boys of C scoring 95% and above are 17 percent of 6000 times 5 over 8.
★Comparing the two expressions and cancelling common factors gives 10 to 17.
★So the ratio of 90-95% boys to 95%-and-above boys in school C is 10 to 17.
