▶Given Deta is ◀

time for 12 neckless = 2 hours

so easily we can find :

$\bold\green{\boxed{1\:hours=6\:neckless}}$

and then

1/2 hours or 30 minutes = 3 neckless.

so time for 1 neckless = 30/3 = 10 minutes.

thus

time for 1 neckless = 10min
so for 9 neckless = 9 × 10 = 90 minutes.

or 1.30 hours
