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
