Mathematics is one such subject in which students can score full marks by following the right preparatrion technique and intensive practice. You cannot learn Maths by just memorizing a set of formulae given in the book. So, it’s very important to solve practice papers, guess papers and sample papers.

CBSE Class 9 Mathematics Solved Practice Paper: Set-III, has been specially prepared by the subject experts after the brief analysis of previous year question papers and the latest examination format. Practicing this paper will definitely help to fine tune your preparations for the board exam 2018.

Some significant features of this paper are:

• Covers the whole syllabus of CBSE class 9 Mathematics.
• Follows the latest examination pattern .
• Each question has been provided with an apt and easy solution.
• Questions have been asked from only those topics which are important from exam point of view.

Practicing this paper will help the students in understanding the depth with which a topic should be studied in order to prepare in a more effective way to score a meritorious position.

CBSE Class 9 Mathematics Solved Practice Paper : Set-I

Structure of this paper is as below:

• The question paper consists of 30 questions divided into four sections A, B, C and D.
• Section A contains 6 questions carrying 1 mark each.
• Section B contains 6 questions carrying 2 marks each.
• Section C contains 10 questions carrying 3 marks each.
• Section D contains 8 questions carrying 4 marks each.
• Total Marks: 80
• Maximum Time: 3 hours

Some sample questions and their solutions from the CBSE Class 9 Mathematics Solved Practice Paper are given below:

Q. If xa/b =1, then find the value of ‘a’.

Sol.

xa/b =1

⟹          xa/b =x0                 [As x0 =  1]

⟹          a/b =0

⟹          a =0

Q. If (1, −2) is a solution of the equation 2xy = p, then find the value of p.

Sol.

2x y = p

Putting x = 1, y = −2, in above equation, we get:

2(1) – (−2) = p

⟹          p = 4

Q. If two opposite angles of a parallelogram are (63 − 3x)° and (4x − 7)°. Find all the angles of the parallelogram.

Sol.

In a parallelogram, the opposite angles are equal.

∴          (63 − 3x)° = (4x − 7)°

⟹       4x + 3x = 63 +7

⟹       7x = 70

⟹       x = 10

(63 − 3x)° = 33°

(4x − 7)° = 33°

Now, sum of all interior angles of a parallelogram = 360°

∴ Sum of the other two opposite angles = 360° - (33° + 33°) = 360° − 66° = 294°

∴ Each of the other two opposite angles = 294/2 = 147°

Hence the four angles of a parallelogram are 33°, 147°, 33°, 147°.
