In the circuit below 1% tolerance resistors were selected so voltages at TP1 thru TP4 were  within 1% of 8.0, 4.0, 2.0, and 1.0 volt respectively. Troubleshoot faulty circuit 1 thru 4 and determine out of tolerance resistor for each circuit.

       Vs = 12.0 Vdc Rs = .2 ohm maximum      
R1 = 40 , R2 = 20, R3 =10, and R4 = 10 ohm + or - 1%
