The average the number of students playing rugby, hockey, badminton and squash is what percentage of the average number of students playing tennis and football?
Answer & explanation
Correct answer: option 1
Average the number of students playing rugby, hockey, badminton and squash
= \(\frac{30 + 60 + 20 + 10}{4}\)
= \(\frac{ 120 }{4}\)
= 30
Average number of students playing tennis and football
= \(\frac{ 20 + 80}{2}\)
= 50
Required percentage = \(\frac{30}{50}\) × 100
= 60%
