1) Hook: The Mango Party Story 🥭🎉

Raju and his friends had a mango party! 🍋 There were 5 friends, and they picked these many mangoes:

• Raju: 8 mangoes
• Priya: 10 mangoes
• Vikram: 7 mangoes
• Neha: 5 mangoes
• Arjun: 10 mangoes

Now, Raju wants to know: How many mangoes did each friend pick on average? 🤔

2) Core Concepts: What is Average?

Average means the middle value or fair share when we share something equally.

To find the average, we:

1. Add all the numbers together.
2. Divide the total by how many numbers there are.

Let's find the average mangoes picked by Raju and his friends:

There are 5 friends, so we divide total mangoes by 5:

Average = Total mangoes ÷ Number of friends = 40 ÷ 5 = 8

So, each friend picked 8 mangoes on average! 🥳
