Answer 1

$\huge\underbrace\mathcal\red{Answer}$

i) let the people surveyed = x

Classical music = 10% of x

10% of x. = 20

10 × x / 100 = 20

x. = 2000/10

x = 200

ii) light

iii) Total CD's 1000

Light = 40% of 1000

= 40 × 1000 / 100

= 400

Folk = 30% of 1000 = 300

Semi Classical. = 200

Classical. = 100
