A wire of length ' $\displaystyle l$ ' and resistance $\displaystyle 100 \Omega$ is divided into $\displaystyle 10$ equal parts. The first $\displaystyle 5$ parts are connected in series while the next $\displaystyle 5$ parts are connected in parallel. The two combinations are again connected in series. The resistance of this final combination is:
