Solution

The correct option is A 150
Time taken to play the music for the first time $= \frac{1}{2} minute = 30 seconds (∵ 1 minute = 60 seconds)$

$∴$ Time taken to play the music $5$ times in a row $= 5 \times 30 = 150 seconds$

Therefore, it will take $150$ seconds to play the music $5$ times in row.
