Aman’s age is three times his son’s age. Ten years ago he was five times his son’s age. Find their present ages
Solution:
Let's form a linear equation for the given problem statement.
Let Aman’s son’s age be x years.
Therefore, Aman’s age will be 3x years.
Ten years ago, their age was (x - 10) years and (3x - 10) years respectively.
According to the question,10 years ago,
Aman’s age = 5 × Aman’s son’s age 10 years ago
3x - 10 = 5(x - 10)
3x - 10 = 5x - 50
2x = 40
x = 20 and 3x = 60
Therefore, Aman and his son's age are 60 and 20 years respectively.
