Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 5 : 6.
Total students in school A = 680
Total boys in school A = 680 × 9/17 = 6120/17 = 360
Total students in school E = 900
Total girls in school B = 900 × 12/25 = 10800/25 = 432
Thus, the required ratio = Total boys in school A : Total girls in school B = 360 : 432 = 5 : 6
