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
