A cricketer whose bowling average is 12.4 runs per wicket, takes 5 wickets for 26 runs and there by decreases his average by 0.4. Find out the number of wickets taken by him till the last match?
Correct Answer: 85
Explanation:
Let x be the number of wickets taken till the last match
According to the question,
(12.4 x + 26) = 12(x + 5)
⇒ 12.4 x + 26 = 12x + 60
⇒ 0.4 x = 34
∴ x = 34/0.4 = 85
