Option 3: 3
Option 4: 1
Correct Answer: 0
Solution : To find the remainder of $8^{8} + 6$ when divided by 7, When 88 is divided by 7, the remainder = $\frac{8^8}{7}→R=1^8=1$ (where R is the remainder) ⇒ $8^{8} + 6→R(1+6)→R(7)$ When 7 is divided by 7, there is no remainder. Hence, the remainder

Question : What is $\tan \frac{\theta}{2}$?
Option 1: $\frac{\cos \theta}{1-\sin \theta}$
Option 2: $\frac{\sin \theta}{1-\cos \theta}$
Option 3: $\frac{\cos \theta}{1-\cos \theta}$
Option 4: $\frac{\sin \theta}{1+\cos \theta}$
Correct Answer: $\frac{\sin \theta}{1+\cos \theta}$
Solution : Given: $\tan\frac{\theta}{2}$ = $\frac{\sin\frac{\theta}{2}}{\cos\frac{\theta}{2}}$ = $\frac{2\sin\frac{\theta}{2}\cos\frac{\theta}{2}}{2\cos^2\frac{\theta}{2}}$ = $\frac{2\sin\frac{\theta}{2}\cos\frac{\theta}{2}}{2\cos^2\frac{\theta}{2}-1 + 1 }$ = $\frac{\sin\theta}{\cos\theta + 1}$ Hence, the correct answer is $\frac{\sin \theta}{\cos\theta + 1}$.

Correct Answer: 8 years
Solution : Simple interest = 9870 – 5250 = Rs. 4620 Rate = 11% Principal = Rs. 5250 Let the time be $t$ years. Simple interest = $\frac{\text{Principal × Rate × Time}}{100}$ ⇒ $4620 = \frac{5250 × 11× t}{100}$ ⇒ $420 = \frac{210t}{4}$ ⇒ $t =
