Brown 1, Red 2. Yellow 10^4, Gold +-5%.
The maximum value means + 5%.
12*10*10*10 * 10 = 120000,
120000*5/100 = 6000.
120000+6000 = 126000ohm.

Because of 5% tolerance(last colour GOLD), this resistance may vary 5% of 120 000.
Minimum resistance value = 120 k - (120k * 0.05) = 114 k ohms.
Maximum resistance value = 120 k + (120k * 0.05) = 126 k ohms.

Minimum resistance value = 120000-6000 = 11400.
Maximum resistance value = 120000+6000 = 126000.

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.

Answer A is right.

Question asking for "The maximum resistance value for a brown, red, yellow, gold".

So,
Brown 1.
Red 2.
Yellow 4.
Gold ±5%.

Hence, 120000 x 5/100,
= 6000.

Now for maximum value,
So, 120000+6000,
= 126000.

Right answer A.

=> brown = 1
=> red = 2
=> yellow = 10^4
=> resistance = 120000
=> tolerance 5%

Max resistance = 120000 + 12000 x 0.05 = 126000.

Brown = 1.

Red = 2.

Yellow = 10^4.

12 x 10000 = 12000.

Ol = + or - 5 tolerance.

12000 x .05 = 6000.

12000+6000 = 126000.

Ans: A.

Why gold tolerance is 5%?

Still I have a doubt. I don't understand how to resistance where three color codes are present with tolerance.

Please clear my doubt.
