If a clock tower strikes once at one o'clock,twice at two o'clock,thrice at three o'clock,then how many times does the clock strike altogether in 24 hours?

Answer 1

Assuming a 24-hour clock and chime, that would be

24/2 (2+23)

If it starts over again with one chime at 1:00, then the sum is

2*12/2(2+11)

Answer 2

the answer is 156
