mk nhanh nhất nha tk mk trước

Sau khi bán 14 quả cam thì số cam có là :

                68 - 14 = 54 (quả)

Lúc sau số quýt có là:

                54 x 3 = 162 (quả)

Lúc đầu số quýt có là :

                162 + 26 = 188 (quả)

Lúc đầu số cam và quýt là :

                188 + 68 = 256 (quả)

                           Đáp số : 256 quả

cam có 68 quả còn quýt thì là 188 quả nhé
