Some sample questions from the solved practice paper are given below
Question: Give the equations of two lines passing through (2, 14). Calculate how many more such lines are there also give reason?
Solution:
The equations of lines are, y = 7x and x + y = 16. When we put x = 2 and y = 14, it satisfies both the equation.
There are infinitely many lines possible as there are infinitely many linear equations, which are satisfied by the coordinates of the point (2, 14).
Question: A cylinder is 3 m height and the circumference of its base is 22 m. Calculate its curved surface area.
Solution:
Here, height of cylinder = 3 m and circumference = 22 m.
Curved surface area = Circumference of the base × Height = 22 × 3= 66 m^{2}.
Question: The value of π upto 50 decimal places are: 3.14, 15, 92, 65, 35, 89, 79, 32, 38, 46, 26, 43, 38, 32, 79, 50, 28, 84, 19, 71, 69, 39, 93, 75, 10.
