Question : The value of $\frac{5-[2+3(2-2 \times 2+5)-5] \div 5}{4 \times 4 \div 4 \text { of }(4+4 \div 4 \text { of } 4)}$ is:
Option 1: $3 \frac{3}{16}$
Option 2: $4 \frac{3}{80}$
Option 3: $\frac{2}{5}$
Option 4: $7 \frac{3}{5}$
Correct Answer: $4 \frac{3}{80}$
Solution :
$\frac{5-[2+3(2-2 \times 2+5)-5] \div 5}{4 \times 4 \div 4 \text { of }(4+4 \div 4 \text { of } 4)}$
$=\frac{5-[2+3(2-2 \times 2+5)-5] \div 5}{4 \times 4 \div 4 \times(4+4 \div 4 \times4)}$
$=\frac{5-[2+3(3)-5] \div 5}{4 \times 4 \div 4 \times(4+\frac{4}{16})}$
$=\frac{5-[2+9-5] \div 5}{4 \times 4 \times\frac{1}{17}}$
$=\frac{5-\frac{6}{5}}{\frac{16}{17}}$
$=\frac{\frac{19}{5}}{\frac{16}{17}}$
$=\frac{19}{5}\times\frac{17}{16}$
$=\frac{323}{80}$
$=4\frac{3}{80}$
Hence, the correct answer is $4\frac{3}{80}$.
