एक क्रिकेटर का गेंदबाजी औसत 12.4 है। अंतिम मैच में 26 रन देकर 5 विकेट लेने के बाद उसका गेंदबाजी औसत 0.2 अंक सुधरकर 12.2 हो गया। अंतिम मैच से पहले उसने कितने विकेट लिए थे?
Detailed Solution & Logic
175
Solution
पुराना गेंदबाजी औसत = 12.4
नया गेंदबाजी औसत = 12.2
अंतिम मैच में = 5 विकेट, 26 रन
मान लेते हैं कि पहले $x$ विकेट लिए थे।
पहले कुल रन = $12.4x$
अंतिम मैच के बाद:
$12.4x + 26 = 12.2(x+5)$
$12.4x + 26 = 12.2x + 61$
$0.2x = 35$
$x = 175$
सही उत्तर: 175
