What is it?

The 'value of a collection of items' means finding the total worth or amount when you put several things together. It's about adding up the individual values of each item to get one final number for the whole group.

Simple Example

Quick Example

Imagine you have a small collection of snacks. You have a packet of biscuits worth ₹10, a small juice box worth ₹15, and a chocolate bar worth ₹20. The value of your snack collection is the total cost if you buy all of them together: ₹10 + ₹15 + ₹20 = ₹45.

Worked Example

Step-by-Step

Let's find the total value of items a vendor sells at a local market.

Step 1: Identify the items and their individual prices.
- Item 1: 1 kg Apples = ₹120
- Item 2: 1 kg Grapes = ₹80
- Item 3: 1 kg Bananas = ₹60

---

Step 2: Write down the value of each item.
- Apples: ₹120
- Grapes: ₹80
- Bananas: ₹60

---

Step 3: Add the values of all the items together.
Total Value = Value of Apples + Value of Grapes + Value of Bananas
Total Value = ₹120 + ₹80 + ₹60

---

Step 4: Perform the addition.
₹120 + ₹80 = ₹200
₹200 + ₹60 = ₹260

---

Answer: The total value of the vendor's collection of fruits is ₹260.
