List of top Physics Questions on Combination of Resistors - Series and Parallel asked in JEECUP

Two resistances combine in series order to provide 50 ohms resultant resistance, and when they combine in parallel order, they provide 8 ohms resultant resistance. Then the value of each resistance is:
In the following figure, the equivalent resistance between ‘A’ and ‘B’ will be
