Question

Two unknown resistances X and Y are connected to left and right gaps of a meter bridge and the balancing point is obtained at 80 cm from left. When a 10 capital omega resistance is connected to parallel to X, the balancing point is 50 cm from left The values of X and Y respectively are

  1. 40 capital omega comma 9 capital omega    
  2. 30 capital omega comma 7.5 capital omega    
  3. 20 capital omega comma 6 capital omega    
  4. 10 capital omega comma 3 capital omega    

The correct answer is: 30 capital omega comma 7.5 capital omega
