A clock chimes 5 times in 4 seconds. How many times will it chime in 10 seconds?

11 times. It chimes at zero and then once every second for 10 seconds.

Why this works

This riddle plays with the timing of the clock's chimes. When the clock chimes 5 times, it actually chimes at the start (0 seconds) and then continues to chime at each second interval (1, 2, 3, 4 seconds). So, from 0 to 4 seconds, there are 5 chimes. If we extend this to 10 seconds, we find it chimes at 0 seconds and then once for each of the next 9 seconds, totaling 11 chimes (1 at 0 seconds + 10 more). This clever twist reveals that counting the initial chime is essential to reaching the correct total!

Common Wrong Answers

“10 times”

This guess assumes the clock chimes once every second for the full 10 seconds, not accounting for the initial chime at zero.

“12 times”

This guess incorrectly adds an extra chime, assuming the clock chimes continuously without considering the actual timing of the chimes.

“5 times”

This guess assumes the clock only chimes at the end of the 10 seconds, ignoring the initial chime at zero.
