A certain book cost 12 more in hardcover than in softcover If the softcover price is two thirds of the hardocver price how much does the book cost in hardcover?

Price of book in soft cover = x

Price of book in hard cover= x+12

Since it is again given that the price in soft cover is 2/3 of hard cover,

x =2/3(x+12)

On solving

x=8

Hence,

price of book in hard cover is x+12

8+12=20
