Step-by-step explanation:
Let Raju age be x, then, Raju'S father age will be 2x.
According to the question,
After 10 year their age will be x + 10 and 2x + 10 respectively.
then,
x + 10 + 2x + 10 = 80.
3x + 20 = 80
3x = 80 - 20 = 60
x = 60 / 3
x = 20 years
hence, the present age of raju is 20 years
and his father age is just 2x = 2*x = 2*20 = 40 years. (* = multiply).

[/tex]
[tex]Age(Raju′sFather)=(2x+10)years
[/tex]
According to the question :
★ After 10 years the sum of their ages would be 80 years.
So,
[tex]\implies(x + 10) +( 2x10) = 80 \\ \implies3x + 20 = 80 \\ \implies3x = 80 - 20 \\ \implies3x = 60 [/tex]
