NOw
let the price of the book be 'x' i.e written price on the book
Price for which a friend bought the book is 25% discount so cost price is #(x-25/100x)#=#(75/100x)# is the cost price of the book.
Now the book is again sold at x price,
PROFIT for the book is the amount remained
HENCE,
Profit=selling price-cost price =#(x-75/100x)#=25/100x
Hence 25% of the the original price written on the book
