A dealer offers a cash discount of 16% and still makes a profit of 25% when he further allows 60 articles to be sold at the cost price of 50 articles to a particular sticky bargainer. How much percent above the cost price were his articles listed?	Choose the correct choice from the following options.
A) 50 %
B) 60 %
C) 70 %
D) 75 %
E) 78 + ( 4 / 7 ) %

Rationale: "given cash discount - 16 % profit - 25 % items sold - 60 price sold at = list price of 50 assume list price = $ 10 total invoice = $ 500 - 16 % cash discount = $ 420 let cost price of 60 items be x so total cost = 60 * x given the shopkeeper had a profit of 25 % 60 * x * 125 / 100 = 420 or x = $ 7 * 4 / 5 = $ 28 / 5 which means his products were listed at $ 10 which is a 78 + ( 4 / 7 ) % markup over $ 28 / 5 answer e"
Answer: E
