Question

a man is 30 years older than his son. in 12 years the man will be 3 times as old as his son find their present age

Answer 1

let the present age of son be x years

present age of father will be x + 30 years

After 12 years;

son's age = x + 12

father's age = x + 30 +12 = x + 42

A/q ;

x + 42 = 3 ( x + 12 )

or, x + 42 = 3x + 36

or, 2x = 42 - 36 = 6

so, x = 6/2 = 3 years


So, son's present age = 3 years

father's present age = 3 + 30 = 33 years
