The value of 1 - 3 ÷ 6\, of 2 + ( 4 ÷ 4\, of 1/4 ) ÷ 8 + ( 4 × 8 ÷ 1/4 ) × 1/8\, is:

Answer: Option A

$$\begin{array}{rl}& 1-3÷6\text{of }2+\left(4÷4\text{of }\frac{1}{4}\right)÷8+\left(4\times 8÷\frac{1}{4}\right)\times \frac{1}{8}\\ & =1-\frac{3}{12}+\left(\frac{4}{1}\right)\times \frac{1}{8}+\frac{4\times 8\times 4}{8}\\ & =1-\frac{1}{4}+\frac{1}{2}+16\\ & =\frac{69}{4}\end{array}$$
