Answer :

Sure! Let's determine the cost of one pen from a cart of 24 pens that costs a total of ₹2986.80. Here's the detailed step-by-step solution:

1. Understand the Total Cost and Quantity:
- We know that the total cost of 24 pens is ₹2986.80.
- We need to find out the cost of just one pen.

2. Setup the Problem:
- Let the cost of one pen be denoted by [tex]\( C \)[/tex].

3. Formulate the Division:
- Since the total cost is for 24 pens, we can divide the total cost by the number of pens to find the cost of one pen.
- This translates to: [tex]\( C = \frac{\text{Total Cost}}{\text{Number of Pens}} \)[/tex]

4. Plug in the Numbers:
- The total cost is ₹2986.80.
- The number of pens is 24.

Therefore,
[tex]\[ C = \frac{2986.80}{24} \][/tex]

5. Perform the Division:
- When we divide ₹2986.80 by 24, we get:
[tex]\[ C = 124.45 \][/tex]

6. Conclude the Solution:
- Hence, the cost of one pen is ₹124.45.

In summary, if a cart of 24 pens costs ₹2986.80, the cost of one pen is ₹124.45.
