The value of two resistors are

{R_1} = (6 \pm 0.3)k\,\Omega

and

{R_2} = (10 \pm 0.2)k\,\Omega.

The percentage error in the equivalent resistance when they are connected in parallel is

View answer and explanation

Correct option: C

0.10125

Option C (0.10125) is correct because it accurately calculates the percentage error in the equivalent resistance when the resistors are connected in parallel.
