Option 1: 455
Option 2: 465
Option 3: 565
Option 4: 568
Correct Answer: 568
Solution : Given: 124, 235, 346, 457, ?
In the given series, add 111 to the previous number to obtain the next number. 124 + 111 = 235; 235 + 111 = 346; 346 + 111 = 457; 457 + 111 = 568

Question : If $\sin A+\sin ^2 A=1$, then the value of $\cos ^4 A+\cos ^6 A$ is:
Option 1: $\cos A$
Option 2: $\sin A$
Option 3: 1
Option 4: 0
Correct Answer: $\sin A$
Solution : Given: $\sin A+\sin ^2 A=1$ ⇒ $\sin A=1-\sin ^2 A$ ⇒ $\sin A=\cos ^2 A$ ⇒ $\sin^2 A=\cos ^4 A$ Now, $\cos ^4 A+\cos ^6 A$ = $\cos^2 A(\cos ^2 A+\cos ^4 A)$ Putting the values, we get: = $\sin A(\sin A+\sin^2 A)$ Since,

Question : The area of the sector of a circle of radius 12 cm is $32 \pi \;\mathrm{cm}^2$. Find the length of the corresponding arc of the sector.
Option 1: $\frac{16}{3} \pi$ cm
Option 2: $\frac{13}{3} \pi$ cm
Option 3: $\frac{10}{3} \pi$ cm
Option 4: $\frac{8}{3} \pi$ cm
Correct Answer: $\frac{16}{3} \pi$ cm
Solution : Given: The radius of the circle is 12 cm. The area of the sector of a circle is $32\pi$ cm2. Area of the sector = $\pi r^2× \frac{\theta}{360^{\circ}}$ ⇒ $32\pi=\pi ×12^2×\frac{\theta}{360^{\circ}}$ ⇒ $\frac{\theta}{360}=\frac{32}{144}$ ⇒ $\frac{\theta}{360}=\frac{2}{9}$ Length of the arc = $2\pi
