Correct Answer: 31.52
Solution :
$\frac{33}{5}×\frac{33}{5}\div2×3\frac{3}{5}×\frac{2}{5}+\frac{2}{5}×\frac{2}{5}$
= $\frac{33}{5}×\frac{33}{10}×\frac{18}{5}×\frac{2}{5}+\frac{2}{5}×\frac{2}{5}$
= $\frac{19602}{625}+\frac{4}{25}$
= $\frac{19602+100}{625}$
= $\frac{19702}{625}$
= 31.52
Hence, the correct answer is 31.52.
