Solution:

From the given circuit, we find that is ineffective as it is a balanced wheatstone bridge.
Since both the upper resistances are in a series combination, therefore their equivalent resistance .
Similarly both the lower resistances are in a series combination, therefore their equivalent resistance .
Now we see that both the resistance are in a parallel combination.
Therefore equivalent resistance between
and
