Answer 1

Step-by-step explanation:

Given krishna, whose bowling average before his last match was 9.4 runs per wicket, takes five wickets for 19 runs in his last match, thereby decreasing his present average by 0.4 runs per wicket. How many wickets did he take before the last match?

• We need to find the total number of wickets.
• So let the number of wickets till the last match was x
• So bowling average is 9.4 runs per wicket = 9.4 x
• Also he has given 19 runs more
• So we have 9.4 x + 19 when 5 wickets were taken
• So we get 9.4 x + 19 / x + 5 = 9.4 – 0.4 (since 0.4 runs is decreased)
•            9.4 x + 19 = 9x + 45
•           9.4 x – 9 x = 26
•               0.4 x = 26
•              Or x = 26 / 0.4
•               Or x = 65
• Therefore total number of wickets taken by the bowler is 65
