Understanding the Problem
To solve the problem, we need to analyze the earnings and losses from selling pens and pencils. The shopkeeper's financial transactions can be summarized as follows:
- Profit on Selling Pens: The shopkeeper earns a profit of ₹1 for each pen sold.
- Loss on Selling Pencils: The shopkeeper incurs a loss of 40 paise (or ₹0.40) for each pencil sold.
Calculating Total Earnings from Pens
- The shopkeeper sold 45 pens in total.
- Total profit from selling pens = Number of pens sold × Profit per pen
  • Total profit from pens = 45 pens × ₹1 = ₹45


Calculating Total Losses from Pencils
- The shopkeeper incurred a total loss of ₹5 during that month.
- Let the number of pencils sold be represented as "x".
- Total loss from selling pencils = Number of pencils sold × Loss per pencil
  • Total loss from pencils = x × ₹0.40


Setting Up the Equation
The shopkeeper’s overall profit and loss can be expressed in the following equation:
  • Total Profit from Pens - Total Loss from Pencils = Total Loss incurred
  • ₹45 - (x × ₹0.40) = -₹5


Simplifying the Equation
Now, we can solve for “x”:
  • ₹45 - (x × ₹0.40) = -₹5
  • ₹45 + ₹5 = x × ₹0.40
  • ₹50 = x × ₹0.40
  • x = ₹50 / ₹0.40
  • x = 125


Conclusion
The shopkeeper sold 125 pencils during that time period.
