Question 54

What is the value of $$\frac{0.1 \div 0.2 \times 0.3 + 0.4 \times 0.5 \div 0.1}{0.1 \times 0.2 - 0.01}?$$

Solution

$$\frac{\frac{0.1}{0.2}\times\ 0.3+0.4\times\ \frac{0.5}{0.1}}{0.1\times\ 0.2-0.01}$$

$$\frac{0.5\times\ 0.3+0.4\times\ 5}{0.02-0.01}$$

$$\frac{0.15+0.4\times\ 5}{0.01}$$

$$\frac{0.15+2}{0.01}$$

$$\frac{2.15}{0.01}$$

$$215$$

Hence option D is correct answer
