What is it?

When we compare the prices of two or more items, the item that costs a higher amount of money is considered 'more expensive'. It means you need to pay more rupees to buy it.

Simple Example

Quick Example

Imagine you want to buy a packet of biscuits. One packet costs 20 rupees, and another packet costs 35 rupees. The packet that costs 35 rupees is more expensive because 35 is a bigger number than 20.

Worked Example

Step-by-Step

Let's find out which is more expensive: a cricket bat for 750 rupees or a cricket ball for 120 rupees.

Step 1: Identify the prices of the items. Cricket bat price = 750 rupees. Cricket ball price = 120 rupees.
---Step 2: Compare the two prices. We need to see which number is larger.
---Step 3: Look at the hundreds place first. 750 has 7 hundreds, and 120 has 1 hundred.
---Step 4: Since 7 hundreds is greater than 1 hundred, 750 is greater than 120.
---Step 5: Therefore, the cricket bat is more expensive.

Answer: The cricket bat for 750 rupees is more expensive than the cricket ball for 120 rupees.

Why It Matters

Understanding what is more expensive helps you make smart choices with money, which is key in Finance and Economics. It's also used in Data Science to compare values and in everyday decisions like shopping. Knowing this helps you manage your budget wisely.

Common Mistakes

MISTAKE: Thinking a lower number means more expensive | CORRECTION: Remember, 'more expensive' always means the item with the HIGHER price or larger number.

MISTAKE: Comparing only the first digit of multi-digit numbers without considering place value | CORRECTION: Always compare numbers from the leftmost digit (highest place value) to the right. For example, 250 is less than 300, even though 250 has a 5 in the tens place and 300 has a 0.

MISTAKE: Getting confused when items have different units (e.g., comparing a price in rupees to a price in dollars directly) | CORRECTION: Ensure all prices are in the same currency unit (e.g., all in rupees) before comparing them.

Real World Connection

In the Real World

When you use apps like Flipkart or Amazon to shop, they often show you different versions of the same product at various prices. You need to compare these prices to decide which one is more expensive or if a deal is good. Even auto-rickshaw drivers calculate the fare, and you compare it to an Ola/Uber fare to see which ride is more expensive for a certain distance.
