Which indicates a 20% tolerance in resistor color codes?

Explanation:
Resistor tolerance is shown by the last color band on a four-band code, and the presence or absence of that band communicates how much the resistance can vary from its stated value. When there is no tolerance band at all, the resistor is assumed to have a tolerance of ±20%. In contrast, a gold band indicates ±5% tolerance, a silver band ±10%, and a brown band ±1%. So, the absence of a tolerance band is what signals the 20% tolerance described in the question.
