R=200\; \Omega

Initially colour was Red and significant figure of red band is 2.

Now we replace Red with green.

& for green colour it is 5.

So replace 2 with 5 in R value.

So R_{new}=500\; \Omega


Option 1)

300\; \Omega

Option 2)

100\; \Omega

Option 3)

400\; \Omega

 

Option 4)

500\; \Omega
