Question : Two pillars A and B of the same height are on opposite sides of a road which is 40 m wide. The angles of elevation of the tops of the pillars A and B are $30^{\circ}$ and $45^{\circ}$, respectively, at a point on the road between the pillars. What is the distance (in m ) of the point from the foot of pillar A?
Option 1: $40(\sqrt{3}-1)$
Option 2: $20(2-\sqrt{3})$
Option 3: $20(3-\sqrt{3})$
Option 4: $39 \sqrt{3}$
Correct Answer: $20(3-\sqrt{3})$
Solution : In $\triangle ROS$, $\tan45^\circ = \frac{h}{OS}$ ⇒ $1= \frac{h}{OS}$ $OS = h$ Thus, $QO = (40 - h)$ Now, In $\triangle POQ$, $\tan30^\circ = \frac{h}{40 - h}$ ⇒ $\frac{1}{\sqrt 3} = \frac{h}{(40 - h)}$ ⇒ $40 - h = \sqrt 3 h$ ⇒ $h (\sqrt

Option 2: 10%
Option 3: 5.75%
Option 4: 5%
Correct Answer: 10.25%
Solution : The area of a circle with $r$ as the radius $=\pi r^2$ The radius is increased by $5\%$, the new radius becomes $1.05r$. The new area of the circle $=\pi (1.05r)^2 = 1.1025 \pi r^2$ The increase in the area $=1.1025 \pi r^2 - \pi
