CAT 2003 | Question: 2-86
A car is being driven, in a straight line and at a uniform speed, towards the base of a vertical tower. The top of the tower is observed from the car and, in the process, it takes $10$ minutes for the angle of elevation to change from $45^{\circ}$ to $60^{\circ}$. After how much more time ... ? $5(\sqrt{3} + 1)$ $6(\sqrt{3} + \sqrt{2})$ $7(\sqrt{3} - 1)$ $8(\sqrt{3} - 2)$

CAT 2003 | Question: 1-135
A vertical tower $\text{OP}$ stands at the centre $\text{O}$ of a square $\text{ABCD}.$ Let $h$ and $b$ denote the lengths $\text{OP}$ and $\text{AB}$ respectively. Suppose $\measuredangle \text{APB} = 60^{\circ}$. Then the relationship between $h$ and $b$ can be expressed as $2b^2 = h^2$ $2h^2 = b^2$ $3b^2 = 2h^2$ $3h^2 = 2b^2$
