Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 59.6
The total number of students who passed from school S in 2014 and 2017 = 273 + 247 = 520
The total number of students who appeared from school T in 2015, 2016 and 2017 = 970
90% of 970 = 873.
Required % = (520)/873 × 100 = 59.6%
