Hiệu cân nặng giữa John và Sarah là:
67,5 - 26,5 = 41 (pound)
Nếu cân ngặn của cả John và Sarah cùng bớt đi x pound thì Sarah nặng bằng 1/3 John. Hiệu số phần bằng nhau là:
3 - 1 = 2 (phần)
Mà khi bớt đi ở cả hai số cùng 1 giá trị thì hiệu của chúng vẫn bằng nhau do đó 2 phần ứng với 41 pound. Vậy 1 phần ứng với:
41 : 2 = 20,5 (pound)
Vậy giá trị của x là:
26,5 - 20,5 = 6 (pound)
