Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 27.36%.
Given that
The total number of people who choose their favourite style of dancing of all age group = 28 + 32 + 46 = 106
The total sample indicated that Rock is their favourite style of music = 9 + 7 + 13 = 29
Hence, the required percentage = (29/106) × 100 = 27.36%
