Option 1: 75°
Option 2: 45°
Option 3: 60°
Option 4: 90°

Question : The value of $3\frac{1}{2} - [2\frac{1}{4}+ 1\frac{1}{4} - \frac{1}{2}(1\frac{1}{2}-\frac{1}{3} -\frac{1}{6})]$ is:
Option 1: $\frac{1}{2}$
Option 2: $2\frac{1}{2}$
Option 3: $3\frac{1}{2}$
Option 4: $9\frac{1}{2}$
Correct Answer: $\frac{1}{2}$
Solution : $3\frac{1}{2} - [2\frac{1}{4}+ 1\frac{1}{4} -\frac{1}{2}(1\frac{1}{2}-\frac{1}{3} -\frac{1}{6})]$ $=3\frac{1}{2} -[2\frac{1}{4}+ 1\frac{1}{4} - \frac{1}{2}(\frac{3}{2}-\frac{1}{2})]$ $=3\frac{1}{2} -[2\frac{1}{4}+ 1\frac{1}{4} - \frac{1}{2}\times 1]$ $=3\frac{1}{2} -[\frac{9}{4}+\frac{5}{4} - \frac{1}{2}]$ $=3\frac{1}{2} -[\frac{14}{4} - \frac{1}{2}]$ $=3\frac{1}{2} -[\frac{12}{4}]$ $=\frac{7}{2} -3$ $=\frac{1}{2}$ Hence, the correct answer is $\frac{1}{2}$.
Question : A light wave is incident over a plane surface with velocity x. After reflection, the velocity becomes:
Option 1: x/2
Option 2: x
