Answer:
Father's age=50 years
Son's age=25 years
Step-by-step explanation:
Given:-
Let the father's age be x and son's age be y.
x=2y
x+y=75
Since x=2y, substitute 2y in place of x.
Now:-
2y+y=75
3y=75
y=75/3
y=25
Son's age=25 years
Father's age will be 75-25=50 years
Hope it helps you!

Let the age of his son be y years
Hence,
x+y=75 —(1)
y=75-x —(2)
The difference between their ages:
y-x= (75-x)-x = 75–2x —(3)
According to the second statement,
When the son’s age = y,
(75-x) + (75–2x)+y = 125
150 - 3x + y = 125
3x-y = 25 —(4)
Adding (1) and (4), we get
4x = 100
Hence, x=25 years
y = 75–25 = 50 years
Present age of son = 25 years
Present age of father = 50 years
