Tổng nhóm 1 là:(29+1)x15:2=225(đơn vị)
Tổng nhóm 2 là:(30+2)x15:2=240(đơn vị)

Kết quả đúng nhất là 455 tôi ghi 465 vì trong biểu thức này:
1 + 3 + 5 +7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23 + 25 + 27 + 29 + 2 + 4 + 6 + 8 + 12 + 14 + 16 + 18 + 20 + 22 + 24 + 26 + 28 + 30 =???
ở quãng tôi bôi đậm bạn thiếu 10 thì mới bằng 465 nha
