Answer: a) 20Ω b) 12Ω c) 6Ω d) 10Ω

Explanation:

In (a), the 40Ω and 60Ω resistors are in series, and their resultant is 100Ω. This resistor is in parallel with the 25Ω resistor. Thus, equivalent resistance is 20Ω.

In (b), the two 8Ω resistors are in parallel with each other and produce an equivalent reistance of 4Ω. This equivalent resistance is in series with the other two 4Ω resistors, thus equivalent resistance between A and B is 12Ω.

In (c), the two 5Ω resistors are in series and have a total resistance of 10Ω. Similarly, the two 20Ω resistors produce a resistance of 40Ω. These two equivalent resistances(of 10Ω and 40Ω) are in parallel with the 24Ω resistor. Therefore, the equivalent resistance between A and B is 6Ω.

If you have understood this far, I hope I can leave (d) as an exercise for you ;) Anyways, comment if you need more clarification or explicit calculations.
