Explanation | व्याख्या |
Option (a) is correct Let his average score before playing the 17th match (ie till 16th match) was x As we know, Average = (Runs Scored )/(matches/Innings) So, x = (Runs )/16 ⇒ Runs = 16x After 17th match his runs wil be = 16x + 98 So new average = (16x+98 )/17 = x + 2.5 16x + 98 = 17x + 42.5 x = 55.5 विकल्प (a) सही है। बता दें कि 17वां मैच (यानी 16वां मैच) खेलने से पहले उनका औसत स्कोर x था जैसा कि हम जानते हैं, औसत = (Runs Scored )/(matches/Innings) तो, x = (Runs )/16 ⇒ Runs = 16x 17वें मैच के बाद उसके रन = 16x + 98 होंगे तो नया औसत = (16x+98 )/17 = x + 2.5 16x + 98 = 17x + 42.5 x = 55.5 |
