Answer 1

Given :-

• Profit on selling a Notebook = Rs.5
• Loss on selling a old pen = Rs.1
• In a Particular Month , Total profit was = Rs.185
• Total pen sold = 75

To Find :-

• Total Number of Notebooks Sold ?

Solution :-

Let us Assume That, Total Notebooks Sold were x.

Than,

→ Profit on selling a Notebook = Rs.5

→ Profit on selling x Notebook = x * 5 = Rs.5x

And,

→ Loss on selling a old pen = Rs.1

→ Loss on selling 75 old pen = 1 * 75 = Rs.75 .

So,

→ Total Profit = Profit on Selling x Notebook - Loss on Selling 75 old pen

→ 5x - 75 = 185

→ 5x = 185 + 75

→ 5x = 260

→ x = 52 . (Ans.)

Hence, The shopkeeper Sold 52 Notebook in that particular Month.
