=+1. General-purpose resistors are color-coded with a sequence of four rings that identify the nominal value of the resistance (in ohms) and the plus and minus tolerance (expressed as a percentage of the nominal)

to be expected in the actual resistance. For example, bands (in order) of green, blue, brown, and gold denote a resistor with a nominal value of 560 ohms and a tolerance of 65%. What are the specification limits

(in ohms) for the process that produces such resistors?
