hiệu của tuổi mẹ và tuổi con sẽ không thay đổi theo thời gian nên 4 năm trước mẹ cũng hơn con 30 tuổi
coi số tuổi của mẹ 4 năm trước là 7 phần thì tuổi con 4 năm trước là 1 phần
hiệu số phần bằng nhau là
7-1=6(phần)
tuổi mẹ 4 năm trước là
30:6x7=35 (tuổi)
tuổi mẹ hiện nay là
35+4=39 (tuổi)
tuổi con hiện nay là:
39-30 = 9 (tuổi)
đáp số : tuổi mẹ :39 tuổi
tuổi con :9
