What Does Class 9 Maths Chapter 2 Linear Polynomials Exercise 2.2 Cover?

This exercise has two parts. First you find the value of a polynomial by putting a given number in place of the variable. Then you meet word problems on ages, coins, and lengths. In each one you name the unknown with a letter, write the other quantities in terms of it, and form a linear equation. Solving that equation gives the answer. This is the heart of Linear Polynomials.

Linear Polynomials Exercise 2.2 Question Breakdown

The exercise has seven questions. The first two ask for values, and the rest are word problems.

Sample Solved Question from Exercise 2.2

Here is Question 3, solved step by step, so you can see how words become an equation.

Question: The present age of Salil's mother is three times Salil's present age. After 5 years, their ages will add up to 70 years. Find their present ages.

Step 1. Let Salil's present age be x years. Then his mother's age is 3x years.

Step 2. After 5 years, Salil is x + 5 and his mother is 3x + 5.

Step 3. Their future ages add up to 70, so (x + 5) + (3x + 5) = 70.

Step 4. Simplify to 4x + 10 = 70, so 4x = 60 and x = 15.

Final answer. Salil is 15 years old and his mother is 45 years old.

How to Use These Linear Polynomials Exercise 2.2 Solutions

Read the word problem twice, then try to form the equation on your own. Open the Collegedunia solution only to check your setup and final answer.

• Write a "let x be..." line for every word problem before you calculate.
• Always verify your answer by putting it back into the story.
• Practise these before your Class 9 annual exam to gain speed and accuracy.
