Henry purchased 3 items during a sale. He received a 20 percent discount of the regular price of the most
expensive item and a 10 percent discount off the regular price of the other 2 items. Was the total amount of
the 3 discounts greater than 15 percent of the sum of regular prices of the 3 items?
(1) The regular price of the most expensive item was $50, and the regular price of the next most expensive
item was $20.
(2) The regular price of the least expensive item was $15

Well the popular answer is A, and some threads in btg state that the explanation. I have only one question.

How can the "other 2 items" be same as "next most expensive" item?
