An unknown resistance 
is connected in series with a resistance of 10
. This combination is connected to one gap of meter bridge while a resistance 
is connected in the other gap. The balance point is at 50 cm, Now, when the 10
resistance is removed the balance point shifts 40cm. The value of 
(in ohm) is
