Wrong answer.
Answer is according to resistor color code.
B B R O Y Great Britain Very Good Wife.
It shows black, brown, red, orange, yellow, green, blue, violet, grey, and white in 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 respectively.
That's why resistance is 120000.
And tolerance of gold is 5%.
So it become 120000+6000 = 126000.

First two colors are digits: Brown-1 & red -2.
Third color yellow is multiplier: Yellow -10000.
Last color is tolerance: Gold- 5%.
(12*10000)+/_(5% of 120000) = 126000 (max).
Third color yellow is multiplier: Yellow -10000.
Last color is tolerance: Gold- 5%.
(12*10000)+/_(5% of 120000) = 126000 (max).

I need a separate resistance value and how calculate the correct answer?

Answer is right were we have to add max resistance i.e. 120000+5% = 126000 ohms.

@Dalmar is Right.
Why we adding 6000?
Because they asking the maximum resistance value. So we should add the tolerance of gold for 120000(120000*.05 = 6000).
If they ask minimum value we need to subtract 6000 from 120000.

The right answer is 120000 Ohms + 6000 Ohms = 126000.
120000*.05 = 6000 the tolerance of gold.
120000*.05 = 6000 the tolerance of gold.

I got answers 120000, by not adding +_ 5%. By adding 5% the answer is 126000.

Brown - 1.
Red - 2.
Yellow - 4.
Brown red yellow,
12*10^4=120000.
Tolerance 5%.
Tolerance 5*(120000/100)=6000.
So 120000+6000=126000.
Answer is 126000.
Red - 2.
Yellow - 4.
Brown red yellow,
12*10^4=120000.
Tolerance 5%.
Tolerance 5*(120000/100)=6000.
So 120000+6000=126000.
Answer is 126000.

Answer is 126000.
Because,
Brown-1.
Red-2.
Yellow-4.
Gold-tolerance of 5%.
120000 + 5% = 126000.
Because,
Brown-1.
Red-2.
Yellow-4.
Gold-tolerance of 5%.
120000 + 5% = 126000.
