• Total age of 5 players = 22*11 = 242
  Total age of 5 players and 1 coach = 23*12 = 276
  so the age of coach =( Total age of 5 players and 1 coach ) - (Total age of 5 players) = 34 yrs

• Since (a+b+c+d+e+f+g+h+i+j+k)/11=22
  So (a+b+c+d+e+f+g+h+i+j+k=22*11) ==242
  Now if it added Coach age then it become......
  (a+b+c+d+e+f+g+h+i+j+k+l)=12*23 ===276
  so-- 276-242=34 that is coach age...Ans

• Age of the coach is = Average age + 12(increase in the age)
  =22+12*1=22=12
  =34
• 10 years agoHelpfull: Yes(0) No(0)
• total age = 11 * 22
  = 242
  if coach age is included, then total age = 12 * 23 =276
  hence age of the coach = 276 - 242
  = 32 years

• total age of hockey players in team is 242 (11*22)
  avg age became 23 when coach age is added (22+1)
  coach age is=(23*12)-(22*11)=34 years.

• simply we can do this short cut by 22+12
  where 22 is initial , later increased by 1 including teacher so 12*1=12
  therfore 34

• when there were 11 player then avg age was 22 age so total age of 11 player 11*22=242 ,now 12 player 11 +1 coach included now avg become 23 years so total become 276 finally coach age is 34 years.

• since age is increased by 1, i.e avegare age is 23
  1 has to be added to all 11 players
  and new age that is added should also be 23
  therefore total new age is 11*1+23=34

• Sol ans: 34
  formuala of people joining a group:
  A1=22, n=11
  A1*n + coach of age = (A1+1) * (n + 1)
  22*11 + c = 12*23
  c= 34

• let coach age x
  so : 22 *11 + x = 23 * 112
  x = 276-242=34
  x = 34
