Correct option is C

Given: ​

​$$\left( \frac{1}{10} \div \frac{16}{100} \right)\ \text{ of }\ \frac{3.2}{0.4} + 120 \div 4\ \text{of}\ 3 \times 10$$ 

Concept Used: ​

Solution: ​

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