A ship’s bell is struck every half hour, starting with one bell at 0030, two bells (meaning the bell is struck twice) at 0100, three bells at 0130 until the cycle is complete with eight bells at 0400.
The cycle then starts again with one bell at 0430, two bells at 0500 and so on.
What is the total number of times the bell is struck between 0015 on one day and 0015 on the following day?
