From the data we are given that:
People who bought CD = 290
People who bought CD alone = 290 – 220 = 70
Therefore the number of people who download music alone is:
People who download music alone = 410 – 220 – 70 = 120
Therefore the total number of people who download music is:
People who download music = 120 + 220 = 340
Answer:
340 people
