The maximum percentage error in the equivalent resistance of two parallel connected resistors of $100 \Omega$ and $900 \Omega$ with each having a maximum $5 \%$ error is ____________\%. (Round off to nearest integer value)

The operating region of the developed torque ( $T_{\mathrm{em}}$ ) and speed ( $\omega$ ) of an induction motor drive is given by the shaded region OQRE in the figure. The load torque $\left(T_L\right)$ characteristic is also shown. The motor drive moves from the initial operating point O to the final operating point S . Which one of the following trajectories will take the shortes time?
