                                                Bài giải:

         Coi tiền vốn của siêu thị là 100 phần trăm thì tiền lãi của siêu thị là 8 phần trăm Tiền bán sản phẩm là:

100+8=108 phần trăm

Giá niêm yết ban đầu (trước khi giảm): 108:(100−10)×100=120 trăm) 

Nếu không giảm thì cửa hàng được lãi: 120−100=20 (phần trăm

                                      

                                              Bài gải

số học sinh giỏi lớp 5b là

           2:1/4 = 8 em 

số học sinh khá của lớp 5 b là

          12 : 1/2 = 24 em 

lớp đó có số học sinh là

            24 + 8 = 32 em 

                      đáp số : a, 32 em 

                                   b, 8 em

Tổng số học sinh của lớp 5B là:

          8 : 25 x 100 = 32 (học sinh)

                       Đáp số: 32 học sinh
