The equivalent resistance between the points A and B is:

 

$\begin {array} {1 1} (A)\;32.5\Omega & \quad (B)\;22.5\Omega \\ (C)\;2.5\Omega & \quad (D)\;42.5\Omega \end {array}$

 

Can you answer this question?

Labeling the intermediate points as X and Y and on using nodal analysis
one gets a very simple picture of the circuit as shown
Clearly, the eq. resistance is $22.5 \: ohms$
Ans : (B)
