Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 25 : 21.
The total number of students who appeared from school Q in 2017 and from school S in 2018 = 350 + 400 = 750.
The total number of students who passed from school R in 2018 and school T in 2014 = 405 + 225 = 630.
Required ratio = 750 : 630 = 25 : 21.
