A table showing the age-wise distribution of the number of people who responded to a survey about their favorite style of dance.
Percentage of x from y = 100x/y
The total number of respondents below 30 years age, who chose Dandiya = 7 + 8 =15
The total number of respondents till the age of 30 years = 34 + 36 = 70
The percentage of the total respondents below 30 years who chose Dandiya as their favorite dance = 15(100)/70 = 21.43%
