Explanation:

Given that SI in 2 years = Rs 400
⇒ SI for 1 year = Rs 400/2 = Rs 200
Hence CI for 1 year = Rs 200
Given compound interest for 2 years = Rs 410
Therefore CI for 2 years = CI for 1st year + CI for 2nd year
⇒ CI for 2nd year = Rs 410 – Rs 200 = Rs 210
That is interest on Rs 200 for 1 year = Rs 210 – Rs 200 = Rs 10

R = 5%

Hence, option 2 is the correct answer.
