Question

Hey guyz if anybody could explain me above numerical plzzz

Answer 1

Here, there are both parallel and series resistors, so we have to combine everything.
First, series,here,Ab,Bd,bc and DC are in series connection.
First combine the series R2 and R3.
Then it will become parallel to BD.
Then find the parallel resistance.
After that the found resistance R and Ab and BD are in series

Answer 2

which 1 or 2 tell me
