Option 3: 5%
Option 4: 10%
Correct Answer: 8%

Question : The ratio of the circumference and diameter of a circle is $22: 7$. If the circumference is $1\frac{4}{7}$ m, then the radius of the circle is:
Option 1: $\frac{1}{3}$ m
Option 2: $\frac{1}{2}$ m
Option 3: $\frac{1}{4}$ m
Option 4: $1$ m
Correct Answer: $\frac{1}{4}$ m
Solution : Given: The ratio of the circumference and diameter of a circle is 22 : 7. Its circumference is $1\frac{4}{7}$ m. Let the radius of the circle be $r$ m. So, diameter $=2r$ and its circumference is $2\pi r$. According to the question, $\frac{\text{Circumference}}{\text{Diameter}}=\frac{22}{7}$ ⇒

Question : If $\sin \theta-\cos \theta=0$, then what is the value of $\sin ^2 \theta+\tan ^2 \theta$ ?
Option 1: $\frac{1}{2}$
Option 2: $1$
Option 3: $\frac{4}{5}$
Option 4: $\frac{3}{2}$
Correct Answer: $\frac{3}{2}$
Solution : Given $\sin \theta-\cos \theta=0$ ⇒ $\sin\theta = \cos\theta$ ⇒ $\frac{\sin\theta}{\cos\theta} = 1$ ⇒ $\tan\theta = 1$ ⇒ $\theta = 45°$ And $\sin\theta = \frac{1}{\sqrt{2}}$ [value of $\sin\theta$ at 45° is $\frac{1}{\sqrt{2}}$] Now, $\sin ^2 \theta+\tan ^2 \theta=(\frac{1}{\sqrt2})^2+1^2$ ⇒ $\frac{1}{2}+1 = \frac{3}{2}$ Hence, the correct answer
