The difference in ages of father and Nam is :
52 - 12 = 40 ( ages )
Since the age difference does not change over time, when the age of the father is 5 times the age of Nam, the age difference of the father and Nam is still 40 years old.
We have a diagram when the father's age is 5 times the age of Nam
Nam's age : |----------|
Father's age : |----------|----------|----------|----------|----------|
age difference is 40
Nam's age when his father's age is 5 times his age is:
40 : ( 5 - 1 ) x 1 = 10 ( ages)
Father's age is 5 times more than Nam's age in previous years is :
12 - 10 = 2 ( years ago )
answer:......
Dịch :
Hiệu số tuổi của 2 bố con hiện nay là :
52 - 12 = 40 ( tuổi )
Vì hiệu số tuổi không thay đổi theo thời gian nên khi tuổi bố gấp tuổi Nam 5 lần thì hiệu số tuổi của 2 bố con vẫn là 40 tuổi
Ta có sơ đồ khi tuổi bố gấp 5 lần tuổi Nam :
Tuổi Nam : |----------|
Tuổi bố : |----------|-----------|-----------|-----------|----------|
Hiệu số tuổi là 40 tuổi
Tuổi Nam khi đó là :
40 : ( 5 - 1 ) x 1 = 10 ( tuổi )
Tuổi bố gấp 5 lần tuổi Nam cách đây số năm là :
12 - 10 = 2 ( năm trước )
Đáp số:.....
