Question : If $3\left(\cot ^2 \theta-\cos ^2 \theta\right)=1-\sin ^2 \theta, 0^{\circ}<\theta<90^{\circ}$, then $\theta$ is equal to:
Option 1: $30^{\circ}$
Option 2: $60^{\circ}$
Option 3: $45^{\circ}$
Option 4: $15^{\circ}$
Correct Answer: $60^{\circ}$
Solution : Given: $3\left(\cot ^2 \theta-\cos ^2 \theta\right)=1-\sin ^2 \theta$ ⇒ $3\left(\cot ^2 \theta-\cos ^2 \theta\right)=\cos ^2 \theta$ ⇒ $3\cot ^2 \theta = 4\cos ^2 \theta$ ⇒ $\frac{3\cos^2\theta}{\sin^2 \theta} = 4\cos ^2 \theta$ ⇒ $\sin^2 \theta = \frac{3}{4}$ ⇒ $\sin \theta = \frac{\sqrt3}{2}$ ⇒ $\theta = 60^{\circ}$
Question : Pipes A, B, and C can fill a tank in 15, 30 and 40 hours, respectively. Pipes A, B, and C are opened at 6 a.m., 8 a.m., and 10 a.m. on the same day. When will the tank be full?
