Step-by-step explanation: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

Now,

☞ 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
