the average age of cricket team of 11 players is the same as it was 3 years back because 3 of the players whose current average age of 33 years were replaced by 3 youngsters.the average age of the newcomers is how much.?

• 22 years
  
  Let the present total age of 11 players be 11x
  Their total age before 3 years=11x - (11*3) = 11x -33
  Let the 3 players of average age 33 are replaced by 3 new youngsters of average age of y years, then
  Present total age of 11 players = 11x-33 = 11x - 3*33 + 3*y
  => 3y=66 or y=22

• 8*x+3*30=8*(x+3)+3*y
  3*30=8*3+3*y
  y=22

  3 years before.
  Total Age of 11 player is = 11*33=363
  Present Age of players is (11-3)
  currently 8 old player =8*33+(8*3)=264+24=288
  Avg age of younger player is= 363-288=75
  75/3=25

• let , age of 11-3 =8 players age sum =x ,old players current age p,q,r .youngsters =a ,b ,c
  x+a+b+c/11 =x+p+q+r-(11*3)/11
  also
  p+q+r/3=33 =>p+q+r=99
  putting in one
  a+b+c=66
  a+b+c/3=22

  current_average_age = (p1 + p1 + p1 + ..... + p11) / 11 p1, p2, p3 are young players.
  
  old_average_age_before_three_year = (o1 + o2 + o3 + (p4-3) + (p5-3) +...+ (p11-3)) / 11 = ((o1 + o2 + o3 + p4 + .... + p11) - 24) / 11 o1, o2, o3 are old players which are now replaced by young players.
  
  both average ages are equal so we have
  
  (p1 + p2 + p3 + .... + p11) / 11 = ((33 + 33 + 33 + p4 + p5 + ... + p11) - 24) / 11
  On solving ..
  (p1 + p2 + p3) / 3 = 25
