## 256. Math Puzzle $9 / 86$

In a quartz clock, the quartz crystal oscillates 32768 times in one second.

How much would a clock gain in a day if its quartz oscillated 32769 times, i.e., one more time per second?
$$
\frac{\text { Error }}{\text { Reference Value }}=\frac{1}{32768}=\frac{x}{1 \text{ T}}=\frac{x}{24 \cdot 3600 \text{ s}}
$$

$x=\frac{86400 \text{ s}}{32768}=2.64$ seconds

If the quartz oscillates one more time in a second, the clock will gain 2.64 seconds per day.
