Question 1056383
.
A man sold a book by mistake at 120% of the marked price instead of discounting the marked price by 20%. 
If he sold the book for P14.40, what was the price for which he should have sold the book?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Let x = marked price of the book.


Then 1.2x = P14.40, according to the condition, which gives 


x = {{{14.40/1.2}}} = P12.00.


Then 0.8*12.00 = P9.60 is the price for which he should have sold the book.


<U>Answer</U>.  P9.60.
