RE: My son is half of my age & was 1/3rd of my age 10 yrs back. What is my present age?
 
lets sons age be S and fathers age be F

TODAY SONS AGE IS HALF OF FATHERS AGE

  WE HAVE  S= 1/2 F

10 YEARS AGO IT WAS 1/3RD OF FATHERS AGE

S-10 =1/3(F-10)

SUBSTITUTING ,F =2S IN THE ABOVE EQN WE GET

S AS 20

THATS IS THE SONS PRESENT AGE AND THEREFORE FATHERS PRESENT AGE WILL BE 2S  I.E  2*20 = 40 YR

FATHERS PRESENT AGE IS 40
