Question : The value of $\frac{40+\frac{3}{4} \text { of } 32}{37+\frac{3}{4} \text { of }(34-6)}$ is:
Option 1: $1 \frac{3}{29}$
Option 2: $-1 \frac{3}{29}$
Option 3: $1 \frac{9}{29}$
Option 4: $2 \frac{3}{29}$
Correct Answer: $1 \frac{3}{29}$
Solution : Given: $\frac{40+\frac{3}{4} \text { of } 32}{37+\frac{3}{4} \text { of }(34-6)}$ = $\frac{40+24}{37+\frac{3}{4} \text { of }(28)}$ = $\frac{64}{37+21}$ = $\frac{64}{58}$ = $\frac{32}{29}$ = $1\frac{3}{29}$ Hence, the correct answer is $1\frac{3}{29}$.
Question : The least number of five digits, which has 123 as a factor, is:
Option 1: 10037

Question : If $0 \leq \theta \leq 90^{\circ}$, and $\sin \left(2 \theta+50^{\circ}\right)=\cos \left(4 \theta+16^{\circ}\right)$, then what is the value of $\theta$ (in degrees)?
Option 1: $10^{\circ}$
Option 2: $8^{\circ}$
Option 3: $4^{\circ}$
Option 4: $12^{\circ}$
Correct Answer: $4^{\circ}$
Solution : Given, $\sin \left(2 \theta+50°\right)=\cos \left(4 \theta+16°\right)$ We know, $\sin(90°-\theta)=\cos\theta$ So, $\sin \left(2 \theta+50°\right)=\sin(90°-(4 \theta+16°)$ ⇒ $2\theta+50°=90°-4\theta-16°$ ⇒ $2\theta+4\theta=90°-16°-50°$ ⇒ $6\theta=24°$ $\therefore\theta=4°$ Hence, the correct answer is $4°$.
