What Does Class 9 Maths Chapter 2 Linear Polynomials Exercise 2.3 Cover?

This exercise takes everyday stories about savings, reading, and shapes, and turns them into linear expressions. A linear pattern is one where the same amount is added or removed at each step. You find the start value and the constant change, then write the rule as start value plus the change times n. Reading these two numbers off a story is the key skill of Linear Polynomials here. Once you have the rule, you can find the value at any step without listing every term one by one.

Linear Polynomials Exercise 2.3 Question Breakdown

The exercise has five questions, each built around a real-life situation.

QuestionWhat it asks
Question 1Savings that grow by a fixed amount each month; write the n-th month expression.
Question 2A rally that loses a fixed number of members each hour.
Question 3Area of a rectangle when the length is fixed and the width varies.
Question 4Volume of a box with given length and breadth.
Question 5Pages left when Sarita reads a fixed number each day.

Sample Solved Question from Exercise 2.3

Here is Question 1, solved step by step, so you can see how a savings story becomes an expression.

Question: A student has 500 in her savings account. She gets 150 every month. Find a linear expression for the amount she will have in the n-th month.

Step 1. The start value is 500, the money already in the account.

Step 2. After 1 month she adds 150, giving 500 + 150 = 650.

Step 3. After 2 months she has 500 + 2(150) = 800, so the fixed monthly change is 150.

Step 4. After n months she has added 150n, so the rule is 500 + 150n.

Final answer. The amount in the n-th month is 500 + 150n rupees.

Quick Tip: Read the two numbers straight off the story. The start value is the constant term, and the fixed change each step is the number that multiplies n.

How to Use These Linear Polynomials Exercise 2.3 Solutions

For each story, list the first two or three values before you guess the rule. Then open the Collegedunia solution to confirm your expression matches.

  • Find the start value and the constant change separately.
  • Test your rule by putting n = 1 and n = 2.
  • Revise these patterns before your Class 9 annual exam.

Linear Polynomials Exercise 2.3 NCERT Solutions FAQs

Ques. How many questions are there in Class 9 Maths Exercise 2.3?

Ans. Exercise 2.3 has 5 questions. Each asks you to write a linear expression from a real-life story. Collegedunia solves all of them.

Ques. What is a linear pattern in Exercise 2.3?

Ans. A linear pattern adds or removes the same fixed amount at each step. The rule is start value plus the fixed change times n.

Ques. How do I write the n-th term expression?

Ans. Find the start value and the constant change. If 500 starts and 150 is added each month, the rule is 500 + 150n.

Ques. Can I download the Exercise 2.3 solutions PDF?

Ans. Yes. The Linear Polynomials Exercise 2.3 solutions PDF is free on this page, so you can revise offline before your Class 9 exam.
