Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 29.37%
The number of students who participated in the GK Olympiad = 182 + 200 + 120 + 130 +183
= 815
The number of students who participated in the Science Olympiad = 100 +100 + 150 + 200 + 80 = 630
The required % = [(815 - 630)/630] × 100 = 29.37%
