Answer:
(i) 200 people
(ii) Light music
(iii) 400 Light music CDs,300 Folk music CDs,200 Semi-classical music CDs
Step-by-step explanation:
(i)Let the total number of people be 'x'.
10% of x = 20
10/100 * x = 20
x/10 = 20
x = 200
(ii)Light music as 40% of people like it where as rest of the music are liked by less percent of people.
(iii)No. of light music CDs = percent of people who like this * 1000
= 40% of 1000
= 40/100 * 1000
= 400 CDs
No. of folk music CDs = percent of people who like this * 1000
= 30% of 1000
= 30/100 * 1000
= 300 CDs
No. of semi-classical music CDs = percent of people who like this * 1000
= 20% of 1000
= 20/100 * 1000
= 200 CDs
No. of classical music CDs = percent of people who like this * 1000
= 10% of 1000
= 10/100 * 1000
= 100 CDs
Hope it helps.
