the null point shifts by 10cm. The resistance that should be connected in parallel with (R1 + 10)Ω such that the null point shifts back to its initial position is?

In the experimental set up of metre bridge shown in the figure, the null point is obtained at a distance of 40cm from A. If a 10Ω resistor is connected in series with R1, the null point shifts by 10cm. The resistance that should be connected in parallel with (R1 + 10)Ω such that the null point shifts back to its initial position is?
