Question

Is father's age is three times as old as his son after 15 years the father's age will be two times as old as his son find the present age of the father?

Answer 1

father's age is three times as old as his son,

x  =  3 y 

after 15 years the father's age will be two times as old as his son 

x + 15  = 2( y + 15) 
x  - 2y  =   15 
3y - 2y  =  15 -----> y =15 ,  x  = 45

father age: 45,, son age: 15
