It's to find out if you can recognize obvious errors in an electronic circuit.

Loop 1 -
Loop 2 -
Loop 3 -
Loop 4 -
Rearranging a few things gives
But since components in parallel have the same voltage and the resistance is the same everywhere then we can assume
Thus the resistance in each leg is
And total resistance is given by
