Definition

What is it?

Problem-solving is finding a way to fix a difficulty or challenge. It's like finding the right key for a lock when something isn't working as it should. It involves understanding the problem and then figuring out the best solution.

Simple Example

Quick Example

Imagine you have 20 rupees, and you want to buy a packet of biscuits that costs 12 rupees. The problem is, how much change will you get back? You solve this by subtracting the biscuit price from your money: 20 - 12 = 8 rupees. So, you will get 8 rupees change.

Worked Example

Step-by-Step

PROBLEM: Your mobile phone has 100 MB of data left. You want to watch a short video that uses 30 MB and then send a few photos that use 20 MB. Do you have enough data for both?
--- STEP 1: Understand what you need to find out. You need to know if 100 MB is enough for 30 MB + 20 MB.
--- STEP 2: Calculate the total data needed. Data for video = 30 MB. Data for photos = 20 MB. Total data needed = 30 MB + 20 MB = 50 MB.
--- STEP 3: Compare total data needed with available data. You have 100 MB. You need 50 MB.
--- STEP 4: Decide if you have enough. Since 100 MB is more than 50 MB, you have enough data.
ANSWER: Yes, you have enough data for both.

Why It Matters

Problem-solving helps you make smart decisions every day, from managing your pocket money to planning your studies. It's a key skill for scientists who invent new things, engineers who build bridges, and even doctors who diagnose illnesses. Being a good problem-solver can help you succeed in any career you choose!

Common Mistakes

MISTAKE: Not fully understanding the problem before trying to solve it. | CORRECTION: Always read the problem carefully, maybe twice, and identify what information is given and what you need to find out.

MISTAKE: Jumping directly to an answer without showing the steps. | CORRECTION: Break down the problem into smaller, easier steps. Write down each step, even if it seems simple, to avoid errors.

MISTAKE: Giving up if the first attempt at a solution doesn't work. | CORRECTION: Problem-solving often requires trying different approaches. If one way doesn't work, think about why it failed and try another method.

Practice Questions

Try It Yourself

QUESTION: A cricket team scored 185 runs in the first innings and 210 runs in the second innings. What is their total score? | ANSWER: 185 + 210 = 395 runs

QUESTION: You have 500 rupees. You bought a book for 180 rupees and a pen for 25 rupees. How much money do you have left? | ANSWER: Money spent = 180 + 25 = 205 rupees. Money left = 500 - 205 = 295 rupees.

QUESTION: An auto-rickshaw charges 15 rupees for the first kilometer and 8 rupees for every additional kilometer. If you travel 5 kilometers, how much will the fare be? | ANSWER: Cost for first km = 15 rupees. Additional kilometers = 5 - 1 = 4 km. Cost for additional km = 4 * 8 = 32 rupees. Total fare = 15 + 32 = 47 rupees.

MCQ

Quick Quiz

Which of these is NOT a good step in problem-solving?

Understanding the problem clearly

Thinking about different ways to solve it

Giving up if the first idea doesn't work

Checking your answer at the end

The Correct Answer Is:

Giving up is not a good step; a good problem-solver tries different solutions. Understanding, brainstorming, and checking are all crucial steps in finding a solution.

Real World Connection

In the Real World

Think about how delivery apps like Swiggy or Zomato work. When you order food, the app has to solve a problem: how to get your food from the restaurant to your home as fast as possible. It uses problem-solving logic to figure out the best route for the delivery person, considering traffic, distance, and other orders.
