30 : ( 7 - 2 ) x 2 = 12 ( tuổi )

Sau số năm nữa thì 2 lầ tuổi cha bằng 7 lần tuổi con là:

Tổng các số trong 3 dòng lần lượt là 352; 463 ; 541

=> Tổng các số trong 9 ô vuông bằng 352 + 463 + 541 = 1356

Nếu tính theo các ô trong 3 cột ta có tổng các số trong 9 ô vuông cũng bằng 335 + 687 + 234 = 1256 khác 1356

Nên Không thể viết được 9 số vào 9 ô vuông theo yêu cầu

vì có 9 số nên tất cả các số trong bảng phải là số âm hết vì  số số hạng lẻ thì nhân với nhâu ko thể dương 

nên tất cả các số phải là số âm mới đúng
