Answer 2

Step-by-step explanation:

Given

$si = 440 \\ p = 1000 \\ n = 5 \\ \\ as \: we \: all \: know \: formula \\ \\ si = \frac{p \times n \times r}{100} \\ \\ 440 = \frac{1000 \times 5 \times r}{100} \\ \\ 440 \times 100 = 5000 \times r \\ 44000 = 5000 \times r \\ \\ \frac{44000}{5000} = r \\ \\ r = 8.8\%$
