Question

a man is 26 years older than his son . after 10 years he will be three times old as his son . find thier present age

Answer 1

let the age of son be x
then , age of man = x+26

age of son after 10 yrs = x+10
age of man after 10 yrs = x+26+10=> x+36

according to question ,
x+36 = 3(x+10)
x+36 = 3x+30
6 = 2x
x = 6/2 = 3 yrs

age of son = x = 3 yrs
age of man = x+26 = 26+3 = 29 yrs
hope this helps

Answer 2

Let his son age be x,
x + 26 + 10 = 3(x +10)
        x + 36 = 3x + 30
              2x = 6
                x = 6/2
                x = 3
Hence, the boy's present age is 3 
             His father's age = 26 + x = 26 + 3 = 29
