Answers
Step-by-step explanation:
Given that,
The present age of son is half the present age of his father.
Let the present age of the father be 2x.
Therefore present age of the son = 2x/2 = x years
ATQ,
10 years ago, father's age was thrice as old as his son.
➡ 3(x - 10) = 2x - 10
➡ 3x - 30 = 2x - 10
➡ 3x - 2x = -10 + 30
➡ x = 20
Hence their present ages are :-
Father's present age = 2x = 40 years
His son's present age = x = 20 years
