The following bar chart shows the number of students playing various games on a given day. Study the bar chart carefully and answer the question that follows.
The average number of students playing rugby, hockey, badminton, and squash is what percentage of the average number of students playing tennis and football?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 54.55%
The average number of students playing rugby, hockey, badminton, and squash
= (30 + 60 + 20 + 10)/4 = 120/4 = 30
The average number of students playing tennis and football = (30 + 80)/2 = 55
Hence, the required % = [30/55] × 100 = 54.55%
