Question : The value of $\frac{0.325 \times 0.325+0.175 \times 0.175+25 \times 0.00455}{5 \times 0.0065 \times 3.25-7 \times 0.175 \times 0.025}-\frac{0.5}{1.5}$ is:
Option 1: –3
Option 2: 3
Option 3: –1
Option 4: 0
Correct Answer: 3
Solution : $\frac{0.325 \times 0.325+0.175 \times 0.175+25 \times 0.00455}{5 \times 0.0065 \times 3.25-7 \times 0.175 \times 0.025}-\frac{0.5}{1.5}$ $=\frac{0.325^2+0.175^2+2 \times 0.325 \times0.175}{0.325^2-0.175^2}-\frac{0.5}{1.5}$ $=\frac{(0.325+0.175)^2}{(0.325+0.175)(0.325-0.175)}-\frac{0.5}{1.5}$ $=\frac{(0.325+0.175)}{(0.325-0.175)}-\frac{0.5}{1.5}$ $=\frac{(0.5)}{(0.15)}-\frac{0.5}{1.5}$ $=\frac{10}{3}-\frac{1}{3}$ $=3$ Hence, the correct answer is 3.
