Hint: In the color coding of a carbon resistor every color signifies a fixed value. The first band depicts the 1st value and second color depicts the second value. And the third band represents the power of extent.

The given carbon resistor has three bands brown, black and green. Brown represents value 1, black represents value 0 and green represents 4. So according to their order the value of the carbon resistor should be around $$9 \times {10^5}\Omega - 11 \times {10^5}\Omega$$. These color coding is used to identify the value of carbon resistor easily. Generally carbon resistors have 4 to 5 bands. Where the last band represents the tolerance of the resistor.
