vout = v1 * (r2/r1+r2).
= 24 * (10k/15k),
= 16v.
= 24 * (10k/15k),
= 16v.

What is the use of key=a 50% ?
If this means 50% max of the potentiometer, then the max resistance is 50 ohms. Thus using a voltage divider,
Vout max = 24* 5k/5k + 5k = 12 volts [which is wrong].
Is the key=a 50% a typo? Using the whole value of the potentiometer,
Vout max = 24 *10k/ 5k + 10k = 16 volts.
