A calculator costs ₹ 145. How many calculators can be purchased for ₹...
Understanding the Problem
To determine how many calculators can be bought with ₹ 1,234 after purchasing a book, we need to first account for the cost of the book.
Calculating Total Cost
1. Cost of the Book:
- ₹ 74
2. Remaining Money after Buying the Book:
- Total Money = ₹ 1,234
- Money left after buying the book = Total Money - Cost of the Book
- Money left = ₹ 1,234 - ₹ 74 = ₹ 1,160
Calculating the Number of Calculators
1. Cost of One Calculator:
- ₹ 145
2. Calculating the Number of Calculators:
- Number of calculators = Money left / Cost of one calculator
- Number of calculators = ₹ 1,160 / ₹ 145
3. Performing the Division:
- Dividing ₹ 1,160 by ₹ 145 gives approximately 8.0. Since we can only purchase whole calculators, we take the whole number.
Conclusion
- Thus, the maximum number of calculators that can be purchased after buying the book is 8.
Final Answer
- The correct option is B) 8.
This step-by-step breakdown shows how to efficiently use the budget to buy calculators while considering the purchase of a book.
