Answer:
The present ages of son and father is 6 and 30 respectively.
Explanation :-
Given :
Father's age = Five times his son's age
After 6 years, The age of father will be thrice of his son's age.
To find :
The present ages of father and son.
Solution :
Let the present age of son be x
Therefore, the present age of father be 5x
After 6 years,
Age of son = (x + 6) years
Age of father = (5x + 6) years
According to question,
=> (5x + 6) = 3(x + 6)
=> 5x + 6 = 3x + 18
=> 5x - 3x = 18 - 6
=> 2x = 12
=> x = 12/2
=> x = 6
Hence, the value of x is 6
Now,
The age of son is (x) = 6 years
And the age of father (5x) => 5 × 6 = 30 years
