    \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
