Solving Notebook Cost Calculation
This problem involves finding the quantity of notebooks that can be purchased based on a given price rate.
Calculate Cost Per Notebook
First, determine the cost of a single notebook using the information provided:
- 15 notebooks cost ₹240.
- Cost per notebook = Total Cost / Number of notebooks
- Using LaTeX: Cost per notebook = $\frac{₹240}{15}$
- Calculation: Cost per notebook = ₹16
Calculate Number of Notebooks for ₹992
Next, use the cost per notebook to find out how many can be bought with ₹992:
- Total amount available = ₹992.
- Cost per notebook = ₹16.
- Number of notebooks = Total Amount / Cost per notebook
- Using LaTeX: Number of notebooks = $\frac{₹992}{₹16}$
- Calculation: Number of notebooks = 62
Therefore, 62 notebooks can be bought with ₹992.
