Five years ago, the average age of P and Q was 25. The average age of P, Q and R today is 25. Age of R after 5 years will be

• Present age of P,QandR =3*25=75
  five years ago,total age of P and Q=2*25=50
  Present age of P and Q=50+10=60
  R's present age=75-60=15
  age of R after 5 year will be 20 years

• Let present ages be P, Q, R resp.
  5 years ago
  (P-5+Q-5)/2=25
  so P+Q=40
  Now (P+Q+R)/3=25
  P+Q+R=75
  or 40+R=75
  R=35
  After 5 years R's age will be 40 years.

• the average of p+q is 25 so p+q becomes 50 and five years ago so present p+q is 60
  p+q+r is 75 by solving r is 15 now age of R after 5 years will be 20
