A batsman, in his 12th innings, makes a score of 63 runs and thereby increases his average score by 2. The average of his score after 12th innings is

• a = {11*(a-2)+63}/12
  multiply both sides by 12
  12a = 11(a-2) + 63
  12a = 11a - 22 + 63
  12a - 11a = 41
  a = 41 his average after 12th innings

• x+2=(11x+63)/12
  x=39

• Let 11th innings average score is X,
  and after 12th Average Score will be X + 2,
  (11X + 63) / 12 = X + 2,
  X = 39.
  and X + 2 = 41.
  
  Anser would be 41
