A carbon resistor has three strips of red colour on its surface and a gold strip at one end of it. What is the value of this resistance?

Answer

The given resistor has three strips of red color on it's surface and a golden strip at one end.
Using the color code of resistor we get,
Required resistance, R= 22 x 102 ± 5% Ω. 
Golden has 5 % tolerance.
