The average age of a cricket team of eleven is 22 years. The average age gets increased by 1 year, when the coach age is also included, What is the age of the coach?

Options
1) 34
2) 23
3) 30
4) 40

• Average age of the team=22
  means, (p1+p2+...P11)/11 = 22
  then sum of ages will be, (p1+p2+...p11) = 22*11 = 242.
  
  now age increased by 1 when including coach's age then
  The average will be ,
  
  (p1+p2+....p11+c1)/12 = 23.
  
  now the sum of their ages including the coach will be, ( p1+p2+...p11+c1) = 23*12 = 276.
  
  now sum of ages of players = 242
  sum of ages including the coach = 276
  
  coach age = 276-242 = 34

• 1) 34 years
  
  If age of coach be 'x' years, then new average=(11*22 +x )/(11+1) =(22+1)
  x=12*23 - 11*22 = 34

• Ans. 1) 34 years
  
  total age of 11 players. = 11x22=242.
  
  let "x" is the age of coach then the avg age :
  (22+1)= [(242+x)/12]
  => (23x12)=242+x
  => 276=242+x
  => x= 276-242= 34

• ans: 34
  After adding the coach age the average is 23 and 1 year is added in the age of each player.
  therefore coach age is 23+11=34

• avg of 11=22 and let sum of age be x
  hence, x=11*22=242
  coach age is added then,
  (x+y)/12=23
  =>(242+y)/12=23
  hence y=34 // solving above equation for y
