    240 people didn’t like any of the music type.

    Step-by-step explanation:

    • Step 1: Given total people who took the survey = 1000. Find the number of people who liked each type of music.

    Number of people who liked pop = 30% of 1000 = 30/100 × 1000 = 300

    Number of people who liked rock = 26% of 1000 = 26/100 × 1000 = 260

    Number of people who liked pop = 20% of 1000 = 20/100 × 1000 = 200

    • Step 2: Find the total number of people who didn’t like any of the music type.

    Number of people who didn’t like any of the music type = 1000 – (300 + 260 + 200)

          = 1000 – 760

          = 240

    Answer: answer is B, 240

    Step-by-step explanation:

    30% + 26% + 20% + x = 100%

    76% + x = 100%

    x = 100% – 76%

    x = 24%

    Therefore, 24% of 1000 does not like any of the top three music

    = 24/ 100 x 1000

    = 0.24 × 1000

    = 240
