Question
The average score of a bowler in a series of matches is
28. His average increases by 2 when he takes 60 wickets in the next match. Find the total number of wickets taken before that match.Solution
Let the number of matches before be 'P'.
Wickets before = 28P
(28P + 60) / (P + 1) = 30
=> 28P + 60 = 30P + 30
=> 2P = 30 => P = 15
Total wickets = 28 × 15 = 420
