Step-by-step explanation:
Let,
the age of father is x and two sons age is y .
After 5 years
father age = (x + 5)
sum of the age of his children = ( y+ 10)
from the given information, we have
x = 3y ..... (1)
and then x+5 = 2(y+10)
x - 2y = 15........(2)
from the (1) and (2)
3y - 2y =15 = y= 15
x = 3y
therefore, x = 45
father age is 45.
