Definition

What is it?

Routine problems are everyday situations that have a clear goal and a known way to solve them. You usually follow a set of steps or rules that you've learned before to find the answer. They are like puzzles you've seen many times.

Simple Example

Quick Example

Imagine your school bus is always late by 10 minutes. This is a routine problem because you know the usual time it should arrive, and you know it will be 10 minutes later. You can easily figure out the new arrival time by adding 10 minutes to the original time.

Worked Example

Step-by-Step

PROBLEM: Your mother sends you to the shop to buy 3 packets of biscuits. Each packet costs ₹25. How much money do you need to give the shopkeeper?
---1. Understand the goal: You need to find the total cost of 3 biscuit packets.
---2. Identify known information: One packet costs ₹25. You need 3 packets.
---3. Choose the right operation: Since you're buying multiple items of the same price, you need to multiply.
---4. Perform the calculation: 3 packets * ₹25/packet = ₹75.
---5. State the answer clearly: You need ₹75 to give the shopkeeper.

Why It Matters

Understanding routine problems helps you think clearly and solve everyday challenges, just like how scientists solve experiments or journalists gather facts. This skill is crucial for careers in data science, where you analyze information, or in law, where you apply rules to cases. It teaches you to break down big problems into smaller, manageable steps.

Common Mistakes

MISTAKE: Getting confused and using the wrong operation (like adding instead of multiplying). | CORRECTION: Always read the problem carefully to understand if you need to combine, separate, or find groups, which tells you whether to add, subtract, multiply, or divide.

MISTAKE: Not writing down the steps or showing your work. | CORRECTION: Always write down each step. This helps you track your thinking, find mistakes, and makes it easier for others (like your teacher) to understand your solution.

MISTAKE: Rushing and making calculation errors. | CORRECTION: After solving, always double-check your calculations. For example, if you multiplied, you can try dividing to see if you get back to the original numbers.

MCQ

Quick Quiz

Which of these is a 'routine problem'?

Figuring out how to build a flying car.

Calculating how many pages you need to read to finish a 100-page book in 4 days if you read the same number each day.

Deciding what to name a new type of animal discovered in the Amazon forest.

Inventing a new type of mobile phone that never needs charging.

The Correct Answer Is:

Option B is a routine problem because it has a clear goal (finish the book) and a known method (division) to solve it. The other options are complex, open-ended problems that don't have a simple, known solution.

Real World Connection

In the Real World

When you use a UPI app like PhonePe or Google Pay to send money, the app calculates the total amount and transaction fees, which is a routine problem. Similarly, when a delivery person for Swiggy or Zomato calculates the shortest route between multiple stops, they're solving a series of routine problems using algorithms.
