the number of wickets taken by him till his last match is ?

please give me easy way out​

Answer 1

Answer:

The bowling average indicates the number of runs given by a bowler to take a wicket. Let the bowler of 12.4 bowling average has taken x wickets before his last match. So, number of runs conceded by him are 12.4x.

Number of runs conceded including present match are 12.4x+26 and total wickets taken are x+5 and the new bowling average is 12.4−0.4=12. To find x, NumberofwicketstakenNumberofrunsconceded=Bowlingaverage

or,x+512.4x+26=12

or,x=85

Therefore number of wickets taken by him his last match is 85
