Solve:

$ \left(\frac{1}{10} \div \frac{16}{100}\right)\text{ of } \frac{3.2}{0.4} + 120 \div 4 \text{ of } 3 \times 10 $
$ \frac{1}{10} \div \frac{16}{100} = \frac{1}{10}\times\frac{100}{16} = \frac{10}{16} = \frac{5}{8} $
$ \frac{3.2}{0.4} = 8 $
$ \frac{5}{8} \text{ of } 8 = 5 $
4 of 3 = 12
$ 120 \div 12 \times 10 = 10 \times 10 = 100 $
Total = 5 + 100 = 105
Answer: 105
