Answer:
c) 20 is the correct answer.
The overall resistance acquired is equivalent to 20 since the resulting resistance generated from the resistors that are connected in series is connected with 40 in parallel.
When two resistors of 25 and 15 ohms are connected in series and then connected in parallel with a resistor of 40 ohms, the combined effective resistance is: a) 0.1 Ω b) 10 Ω c) 20 Ω d) 40 Ω
