The below table shows the ratio of girls and boys in the given five schools.
What is the ratio of the number of boys in school C to the number of girls in school E?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 3 : 4
Calculations:
Let the number of total students be 100x
Number of students in school C = 24% of 100x = 24x
Number of students in school E = 15% of 100x = 15x
Number of boys in school C = 24x × 3/8 = 9x
Number of girls in school E = 15x × 4/5 = 12x
Required ratio = 9x : 12x = 3 : 4
