nam is 12 years old. his father is 52 years old. how many years ago his father's age five times his age?
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:.....
In 8 years, his father will be 5 years older than him .
