The printed price of pen = 5

After discount of 10%, price of pen = 5 - 0.5 = 4.5

Profit earned after selling at discounted price = 12.5%

12.5% profit = 1.125 x Price which shopkeeper purchased or Cost Price

1.125 CP = 4.5

CP = 4.5 / 1.125

CP = 4

So, No. of pens sold will be 1800/4

= 450

Marked Price = Rs 5


Find the price after discount:

Discount = 10% of 5 = Rs 0.50

Price after discount = 5 - 0.5 = Rs 4.50


Find the profit:

Profit = 12.5%

Selling Price = 100 + 12.5 = 112.5%

Selling Price = Rs 4.50

112.5% = 4.50

1% = 4.5 ÷ 112.5 = Rs 0.04

12.5% = 0.04 x 12.5 = Rs 0.50


Find the number of pens bought:

Number of pens = 1800 ÷ 0.50 = 3600


Answer:3600 pens were sold
