survey.
plz help ..​

Answer 1

Total people in survey = 10000

Number of people who like folk song only = 3000

Explanation:

0% like none, thus 90% like atleast anyone of them.

Let the total number of people in survey be x.

90x/100 = 70x/100 + 60x/100 - 4000

40x/100 = 4000

x = 400000/40

x = 10000

Total number if people who like folk songs = 70*10000/100

= 7000

Number of people who like folk song only = 7000 - 4000

= 3000
