. There are 2 friends Peter and Paul. Peter age is twice as old as Paul when peter was as old as Paul is now. Sum of the present ages of Peter and Paul is 35.What is the present age of Peter?

• let pauls age be 'a' and peters be 'e'
  e+a=35 (given)
  e=35-a ------eq1
  when peter was as old as paul that is when peter's age was 'a'
  pauls age was a-(e-a) =2a-e
  now peters age is e=2(2a-e)
  e=4a-2e
  3e=4a
  3(35-a)=4a
  105-3a=4a
  a=15
  hence e=20

• heat and trial
  peter age = 21
  21+14=35
  peter at the age of 14 = paul age is 7
  above condition is true

• LET PETER AGE IS X.PAL AGE=35-X
  AGE DIFFERENCE=X-9(X-35)=2X-35
  WHEN PETER WAS AT 35-X THEN PAUL AGE=35-X-(2X-35)=35-3X
  A.T.Q
  (35-3X)*2=X
  X=20
