<result>E</result>
a bookseller sells his books at a 20 % markup in price. if he sells a book for $ 24.00, how much did he pay for it?
subtract(24, multiply(divide(20, const_100), 24))
let the cost price of book = x selling price of book = 24 $ markup % = 20 ( 120 / 100 ) x = 24 = > x = 20 answer e
