Now, The amount after 2nd year will become the principal amount for the 3rd year

$\therefore$ Principal amount, P = Rs 8,820

Compound rate of interest, R = 5% p.a.

Time period, n' = 1 year

$\therefore Interest \:for\: the \:3rd \:year =\frac{8820\times1\times5}{100} = Rs.\ 441$

Therefore, the interest for the 3rd year is Rs 441.
