How many beats will the clock make per day, if every half hour there is 1 beat, and every hour, according to the time.

There are 24 hours a day. This means that the number of “half-hour” beats is 24. Let’s count the number of hourly beats. A mechanical watch has 12 o’clock. That is, there are two circles in a day from 1 to 12 hours.

2 * (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12) = 2 * 13 * 6 = 13 * 12 = 156 hourly beats. This means that a total of 156 + 24 = 180 blows will be made for hours a day.

Answer: 180 beats per day will make the clock.
