Accepted Answer

From the following circuit diagram, ${{{R_1}} \over {{R_3}}} = {{{R_2}} \over {{R_4}}}$, so the given Wheatstone bridge is balanced.
Hence, there is no current in the wire of 10 $\Omega$ resistance.
As,
Now, if the 10 $\Omega$ wire is replaced with 15 $\Omega$ wire, the bridge still remains balanced. Hence, current drawn from battery will be 10A.
