20.

The maximum resistance value for a brown, red, yellow, gold resistor is

A.	126,000 Ω
B.	126,600 Ω
C.	114,000 Ω
D.	132,000 Ω

Answer: Option A

21.

The minimum resistance value for a blue, gray, red, silver resistor is

A.	612 Ω
B.	6,120 Ω
C.	6,800 Ω
D.	6,460 Ω

Answer: Option B

Explanation:

Because of 10% tolerance(last color silver), this resistance may vary 10% of 6800.

Minimum resistance value = 6800 - 680 = 6120

Maximum resistance value = 6800 + 680 = 7480
