Question

Present age of father is 3 more than 3 times his sons age. After 10 years father will be 10 more than twice his son's age.Find their present ages

Answer 1

son is 17 and father is 54

Answer 2

let age of son be x
present age of father =3+3x
after 10 years age of son=10+x
And age of father =10+2(10+x)
age of father is also equal to 3+10+3x
3+3x+10=10+2(10+x)
13+3x=10+20+2x
13+3x=30+2x
x=30-13=17years
age of son at present =17
age of father at present =3+(3×17)
=3+51=54 years
