Q. No.2: A batsman makes a score of 87 runs in the 17th inning and thus increases his average by 3 . Find his average after 17th inning.

A. 39

B. 38

C. 38.5

D. 39.

• ans is 39,first consider avg of 16 matches =y
  then sum of 1st 16 matches =16y
  avg of 17 matches (16y+87)/17=y+3
  solve for ,y= 36,hence acc to the questn avg aftr 17th innings will be 36+3=39

• ans 39. x/16=y
  x+87/17=y+3
  solve these two eqtns y=36 x=576 so after 17 innings y+3 i.e 36+3=39

• up to 16th innings his average is X.
  so total score till then is 16X.
  new score is 16X+87=Y
  new average Y/17=X+3
  By solving the two Eqs, we get
  X=36
  Y=39
  answer is 39

• 576/17=39 total runs =87*16-17*48

• (x+3)17=16x+87
  ==> x= 36
  but we need x+3 = 36 + 3 =39
