                                                    530 000 : 100 * 80 = 424 000 ( đồng )

b, Tỉ số phần trăm giá tiền ban đầu và giá tiền sau khi giảm là :

                                                530 000 : 424 000 * 100% = 125 %

                                                                                   Đáp số : a,424 000 đồng
