Answer:
Son's age = 24 years
Man's age = 48 years
Step-by-step explanation:
Let's take the age of son as x
Man's age = 2x
Twelve years ago,
Son's age= x-12
Man's age= 2x-12
Man is three times as old as his son so,
[tex] \frac{2x - 12}{x - 12 } = \frac{3}{1} [/tex]
Solving for x,
2x-12(1) = x-12(3)
2x-12 = 3x-36
2x-3x = -36+12
-x = - 24
x = 24
So if we substitute the values we get,
Son's age = 24 years
Man's age = 48 years
Hope you understand :)
Step-by-step explanation:
[tex] \underline{ \underline{ \text{Solution}}} : [/tex]
Let the present age of father be ' x ' years and that of the son be ' y ' years. From the first condition ,
- x = 2y ••••••• equation ( i )
From the second condition ,
- x - 12 = 3 ( y - 12 ) ••••• equation ( ii )
Substituting the value of x from equation ( i ) in equation ( ii ) :
[tex] \sf{2y - 12 = 3(y - 12)}[/tex]
Solve for y ( age of the son ) :
⟿ [tex] \sf{2y - 12 = 3y - 36}[/tex]
⟿ [tex] \sf{2y - 3y = - 36 + 12}[/tex]
⟿ [tex] \sf{ - y = - 24}[/tex]
⟿ [tex] \sf{y = 24}[/tex]
Now , Substituting the value of y in equation ( i ) , we get :
[tex] \sf{x = 2 \times 24}[/tex]
⟿ [tex] \sf{x = 48}[/tex]
So, the present age of the father is 48 years and that of the son is 24 years.
Hope I helped ! ツ
