(First color code * 10 + Second color code) * 10^(Third color code) +/- (gold[5%] / silver[10%] / no color[20%]).

Red ---- Red ---- Orange ---- gold.
2 ---- 2 ---- 3 zeros ---- 5% tolerance.
So,
22000 +-5%.
Ans= 22000.

The answer is A.
22000 +-5%.
Ans= 22000.
22000 +-5%.
Ans= 22000.

red =2
red =2
0range =10^3
gold =10%
so value=22,000 ± 10%
red =2
0range =10^3
gold =10%
so value=22,000 ± 10%
