उत्तर

Selling Price of a Pen = 13.20

Discount = 12%

`"Marked Price" = "Selling Price"xx(100/(100-d))`

 `= 13.20xx(100/(100-12))`

`=1320/100xx100/88`

Marked Price = ₹ 15

New Discount = 5%

`"Selling Price" = "Marked Price"xx((100-d)/100)`

`= 15xx((100-5)/100)`

`=15xx95/100`

`=3xx19/4`

New Selling Price = ₹ 14.25
