Question : Directions: Study the bar diagram and answer the questions. The percentage fall in the value from 2000 to 2001 is:
Option 1: 25%
Option 2: 50%
Option 3: 76%

Question : If the diagonals of a rhombus are 16 cm and 30 cm. What is the perimeter (in cm) of the rhombus?
Option 1: 32 cm
Option 2: 64 cm
Option 3: 34 cm
Option 4: 68 cm
Correct Answer: 68 cm
Solution : The diagonals of a rhombus are 16 cm and 30 cm. We know diagonals perpendicularly bisect each other in a rhombus. Side of a rhombus = $\sqrt{(\frac{\text{Diagonal_1}}{2})^2 + (\frac { \text{Diagonal_2}}{2})^2}$ ⇒ Side of rhombus = $\sqrt{(\frac{16}{2})^{2}+ (\frac{30}{2})^{2}}$ ⇒ Side = $\sqrt{82+152} = \sqrt{289}
Question : Let C be a circle with centre O and radius 5 cm. Let PQ be a tangent to the circle and A be the point of tangency. Let B be a point on PQ such that the length of AB is 12 cm. If the line joining O and B intersects the circle at R, find the length of BR (in cm).
Option 1: 2
Option 2: 13
Option 3: 6
Correct Answer: 8
Solution : Given: Radius = 5 cm OA = 12 cm We know that the angle between a tangent to a circle and the radius through the point of contact is always a right angle. From figure, OA = OR = 5 cm (radius) By applying Pythagoras
