Trung bình cộng của hai số chẵn bằng 624. Tìm 2 số đó biết giữa chúng có 2 số chẵn khác.
Mình cũng muốn các bạn tham gia www.duolingo.com Ai có nick rồi thì nói với mình nick nhé ~
Lê Phương Anh
Tổng 2 số chẵn là :
624 x 2 = 1248
Vì giữa 2 số có 35 số chẵn khác nên hiệu giữa 2 số chẵn đó là :
2 x ﴾ 35 + 2 ‐ 1 ﴿ = 72
Số bé là :
﴾ 1248 ‐ 72 ﴿ : 2 = 588
Số lớn là :
1248 ‐ 588 = 660
